    South Australia emergency services live audio and pagers

    This is something which could be useful going into fire season here in South Australia. It is a feed from the SA government trunk radio network.

    I will see if there are more feeds like this that also include the regional and remote area trunks. This sounds like the Adelaide CBD feed.

    Hear the GRN live here:

    I thought this was cool. It may come in handy for Ham Radio.

    D-Star IC2820 VK5 ICF – updated

    I recently downloaded the IC2820 V19a channel mapping for the ICOM 2820 from IC2820_VK5RWN_C_V19a.icf.

    After uploading the file to the radio I discovered that many of the simplex channels I previously used on my IC2820 were now gone (not surprising). Lucky I copied the original radio config to a new .icf file before I uploaded the new one.

    One frustrating thing I did discovered with the 2820 cloning software is that the EXPORT function appears to only export the stations heard by the radio to CSV and no the full radio configuration. A full copy of the config can only be stored in the native .icf file format, which is full of numbers (looks like memory contents). So manually editing the config file was out of the question.



    For those who have played with the software (CS-2820), you may have noticed that you can only spawn one instance. So copying the frequencies from my old config to the new config (the above link plus my original mapping) was not going to be as easy as I thought i.e export both and combine in notepad or excel.

    I discovered that it is possible to highlight and copy multiple lines in the channel map (only in the application copy buffer, not in the windows clipboard – can’t copy it to excel or notepad). Once you have copied the lines you want from the original config select ‘File – Open’ from the menu and open the new config (in my case the above file – renamed). If the application has not been closed it is possible to place the cursor where you want to add the channels from the old config and select paste (control v) and the copied rows will then be placed into the new config.

    I originally based my simplex frequencies (2m and 70cm) on the AREG frequencies in the modified ham Motorola Syntrx radios located on the AREG website.

    VK5 – 2M Syntrx Frequency Plan – Issued 22/11/2005
    VK5 – 70cm Syntrx Frequency Plan – Issued 22/11/2005

    The new updated file containing the new D-Star mapping, supplemented by my slightly modified AREG simplex channels can be located here.


    Here is a screen print.

    CS-2820 copy screen print

    CS-2820 copy screen print

    This is the .icf file converted to a .xls (csv to xls – from excel). The conversion can be done with CHIRP.

    The Freq and channel file: 2820h

    I hope this information helps someone.

    How To Hijack Fast Food Drive-Thru Frequencies

    This is an article I found on the Phone Losers site I thought I would copy here so I can give it a go at some stage.

    How To Hijack Fast Food Drive-Thru Frequencies

    A few years back, some friends and I were messing around with a Taco Bell’s drive-thru frequencies. RijilV and isotek showed me how easy it was to hijack the frequencies of just about any fast food restaurant with a very simple mod to a ham radio. The radios they used were Yaesu VX-5 and VX-7 models. We had a few weeks of occasional fun, sitting a few parking lots away and saying all kinds of horrible things to potential fast food customers. For the most part, I didn’t record any of it. But you can find a few clips of our fast food hijinks if you scroll down on the PLA Sound Clips Archive page.

    Finally we decided to capture a bit of our FCC violations on video. But instead of capturing actual customers being harassed by us as they placed an order, I drove through the Taco Bell drive-thru myself with a video camera sitting on the dashboard. As I attempted to place my order, RijilV informed me of some crazy new Taco Bell policies and a manager immediately rushed out to explain to me that I wasn’t actually talking to an employee. Here is that video:

    After spending several years on Google Video and YouTube, it’s been watched approximately 20,000 times. And of those 20,000 people who have viewed it, approximately all of them have emailed me and asked me what kind of radio we used and how can they use a radio to do the same thing. So in the spirit of April 1st and in order to quell the number of emails sent to me and posts on the PLA Forums asking the same thing, I’ve decided to write this tutorial to help those people out.

    But I’m not going to explain how to modify a Yaesu VX5 or a Yaesu VX7. A simple Google search will show you how to modify these ham radios. The problem with these mods is that, even though they’re fairly simple, you have to buy the radios which could cost you anywhere from $200 – $400. Then, after removing a couple solder points, you have to learn how to use it, you have to look up fast food frequency lists, you have to understand the difference between the transmit frequencies and the receive frequencies and you have to scroll through PL tones using trial and error to find the correct one.

    Or how about we do this a different way. A way that uses a couple items that you might already have in your home. You can easily modify most old CB radios in a way that will allow them to transmit directly to drive-thru frequencies. You won’t have to scroll through hundreds of possible drive-thru frequencies, because a CB radio’s channels line up in exactly the same way as most drive-thru’s channels, only at a higher frequency. How do you get your CB radio to run at a higher frequency? A simple replacement of the crystal inside, with a 6.5536 MHz crystal. This triples the megahertz that are broadcast on and there is no learning required. You just take the modified CB radio to a fast food restaurant and start broadcasting to the customers.

    “But RBCP, I don’t have a 6.5536 MHz crystal lying around my house,” you might be whining at this point. But this isn’t true. Just about any house has several 6.5536 MHz crystals in them if you know where to look. This just happens to be the exact same crystal that you can find in electric heaters, hair dryers, electric stoves, curling irons, electric hot water heaters, irons, and toasters. These crystals are in just about any item that has heated coils and are used to control the frequency of the heating elements so that they don’t burn your house down.

    So for this modification you need…

    • 1 CB radio. It has to be a 40 channel CB radio with a digital display, which includes just about any CB radio manufactured after the mid 1980’s. The old 23 channel CBs from the 1970’s will not work. It can even be a walkie talkie CB radio. If you don’t have one, you can find one at Goodwill or a yard sale for probably less than $10.
    • 1 toaster. (Or other item with heating elements inside.) A toaster is the most ideal to use, because it’s almost guaranteed to have the crystal inside of it. It’s more common to find curling irons and hair dryers that don’t. Again, it should be a toaster manufactured within the past 20 years or so. Before that they didn’t have crystal requirements for toaster manufacturers. (And incidentally, there were a lot more electrical house fires back then.) Goodwill will probably have a toaster for less than $10.
    • 1 soldering iron and solder. Don’t worry if you don’t have soldering experience. It’s actually pretty easy. Click here for a soldering tutorial. You can purchase a soldering iron at Radio Shack or Sears for about $10.
    • A few screwdrivers

    Even if you have to buy all these materials, you’re only out $30. That’s a lot better than the $300 you might end up spending on a Yaesu radio. And some of you might already have all these items so you don’t have to pay anything. Ask a friend or a relative if they’ve got an old toaster or CB radio lying around that they don’t need.

    First you’ll want to take apart your toaster. This isn’t too hard. Just flip it upside down and start removing the screws. You’ll probably need to pull off the plastic lever and knobs before you remove the top of the toaster. Once you have the top off, you’ll see a green or brown circuit board inside.

    Flip the circuit board down and you’ll see all the components on the other side, including the 6.5536 MHz crystal. The crystal is silver and will have 6.5 stamped on the side of it. In the picture below, I’ve used an arrow to show you where it’s located.

    The crystal is likely in a different spot in other toasters, but it’s hard to mistake for any other electronic component. The crystal will have some form of 6.5 stamped on the side of it. In my toaster, it showed 6.55-12. While the official frequency needed is 6.5536 MHz, anything within 1.6 megahertz will work. So don’t worry if your crystal just says 6.5 or 6.50 – it’s all the same for our purposes.

    It’s kind of hard to see what I’m doing in the picture above, but I’m heating up the leads on the crystal from underneath with my soldering iron to melt the solder, and I’m pulling on the crystal from above with a pair of needle nose pliers. It only takes a few seconds to get the crystal out of the toaster.

    Now that the crystal is out of your toaster, throw your toaster away! Do not attempt to use it once the crystal is removed. Remember, the crystal is in there for safety and using your toaster without the crystal could burn your toast and/or start a kitchen fire. It’s likely your toaster won’t even turn on with the missing crystal, but please don’t even try. Just throw it away.

    As I mentioned before, just about any brand and model of CB radio will work, as long as it has the digital display on it. Which means, just about any CB radio manufactured after the mid 1980’s. These are the kinds of CB radios whose frequencies are controlled by a single crystal inside of them. For my mod, I used a Radio Shack TRC-207 walkie talkie CB radio, which is pictured above. I prefer using a walkie talkie CB radio because it doesn’t requiring sticking a huge CB antenna on the roof of my car which might be noticed if a fast food employee starts looking around the parking lot for the culprits.

    Taking apart your CB radio is just as easy as taking apart the toaster. Remove the screws and pop it open. You may or may not have to lift up the circuit board inside to find the crystal inside. In my particular model, the crystal actually plugged into a socket so I didn’t need to even desolder the old crystal. I just pulled it out with my fingers and then plugged in the new 6.55 MHz crystal. I don’t know how common this is, because in other CB radios that I’ve modified the crystal was soldered to the circuit board, just like in the toaster.

    Put your CB back together and test it to make sure it’s working. You’re finished! Obviously, you won’t be able to talk on normal CB channels anymore since your CB is transmitting and receiving at a much higher frequency now. But who cares, CB channels are lame anyway. Let’s hop in the car and drive to our nearest fast food establishment to test it out.

    Sit near the drive-thru and wait for a customer to pull up. While the customer is talking to the drive-thru speaker, start flipping through your channels until you hear them talking. I’ve found that most drive thrus end up being somewhere in the 16 – 25 channel range. I’ve never found one above channel 30 and only a few on channels 1 through 15. It all depends on how their drive-thru is set up and what frequencies they’re using. Anyway, push down your talk button and start talking to the customer.

    The cool thing about using a CB radio to transmit on drive-thru frequencies is that a CB is designed to work for several miles. The headsets that those fast food people wear are only designed to work for about 100 feet. So you can easily overpower the employees, even if you’re several parking lots away. In fact, you may be inadvertently screwing with several other drive-thrus in town without even knowing it. This is more likely when you’re using the kind of CB radio that’s supposed to be installed in a car. Those usually run on 5 watts and can cover an entire city. This is another reason I like to use my walkie talkie. It’s lucky if it will work for even a mile, so I’m only harassing one restaurant at a time.

    If you found this tutorial useful, you might also enjoy the video I’ve made on the same subject. It includes much of the same information in this tutorial, but also includes actual footage of us messing with a drive-thru with this CB mod. Enjoy!

    Amateur Radio and Radhaz

    Something I have been very wary about for some year had begun to be better understood over the last few years.

    I remember a doctor from an Adelaide hospital who presented at an IEEE meeting saying “on the record there hasn’t been enough research performed to prove that electromagnetic radiation causes cancer, but off the record I have seen enough cases where I am convinces it does”.

    This simple statement and other examples provided during the presentation really drove home that we must be wary and respectful when using an existing near electromagnetic emitting devices.

    This article came from the local South Australia Amature Radio Experimentes Group Website – Thanks for allthe great work. See link

    General Background Information

    The question of Radhaz has to be considered when you are constructing an Amateur Radio station that will operate near members of the general public as well as your self.

    The responsibility for ensuring that the operation of an Amateur Radio transmitting station is operating with in the ARPANSA and ACMA guidelines is souly the responsibility of the amateur radio operator in control of the radio transmitter.

    As the standard for Radiation Protection Standard for Maximum Exposure Levels to Radiofrequency Fields – 3 kHz to 300 GHz changes from time to time. The information on this web site will become out of date. AREG accepts no responsibility for the information presented on this page, the relative orginsations should be consolted for the latest up to date information.

    For complete appraisal of your situation, you should consult one of the many orginsations that are NATA certified.

    As of March 1st 2003, the Australian Communications & Media Authority (ACMA) introduced new limits for human exposure to electromagnetic radiation (EMR) covering all mobile transmitters such as remote controlled toys, walkie-talkies and hand held two-way radios as well as radio communications installations such as broadcast towers and amateur radio stations.

    Under the new regulations, mandatory limits are set by the Australian Radiation Protection and Nuclear Safety Agency (ARPANSA) and people who hold a licence for a radiocommunications facility will have to comply, and in certain cases, hold records demonstrating compliance with the limits.

    For a complete details on the ARPANSA standard, please refer to the link below and the ARPANSA web site.


    The RPS No:3 Standard is known as, Radiation Protection Standard for Maximum Exposure Levels to Radiofrequency Fields — 3 kHz to 300 GHz (2002).

    This Standard specifies limits of human exposure to radiofrequency (RF) fields in the frequency range 3 kHz to 300 GHz, to prevent adverse health effects. These limits are defined in terms of basic restrictions for exposure of all or a part of the human body. Relevant derived reference levels are also provided as a practical means of showing compliance with the basic restrictions. In particular, this Standard specifies the following:

    (a) Basic restrictions for occupational exposure with corresponding derived reference levels as a function of frequency.

    (b) Basic restrictions for general public exposure, with corresponding derived reference levels as a function of frequency.

    (c) Equipment and usage parameters in order to assist in the determination of compliance with this Standard.
    The limits specified in this Standard are intended to be used as a basis for planning work procedures, designing protective facilities, the assessment of the efficacy of protective measures and practices, and guidance on health surveillance

    IDEAS page is all about putting up design and other general ideas. These may include part circuits or drawings of things that we have thought other people may be interested in. In general don’t expect a complete package, as this page is only meant to give you some ideas on what we have done. So you can further your own experimentation.

    ISO 14443 contactless card

    An international standard for proximity or contactless smart card communication

    ISO 14443 contactless card

    ISO 14443 is an international standard which describes how contactless cards and terminals should work to ensure industry-wide compatibility, for example in identity, security, payment, mass-transit and access control applications.

    ISO standards are developed by the ISO, the International Organization for Standardization. Technical committees comprising experts from the industrial, technical and business sectors develop the standards to increase levels of quality, reliability and interoperability on a global scale.

    Gemplus has always had a strong involvement in ISO definition of the chip card standards, and has been represented in the development of this international standard. The ISO 14443 is divided into 4 separate parts outlining physical characteristics, radio frequency power and signal interface, initialization and anti-collision and transmission protocol.

    Gemplus has developed a wide range of contactless payment solutions based on the ISO 14443 international standard. The speed and convenience of contactless technology has created a significant demand for this sort of solution in environments such as fast food restaurants, gas stations, public transport services, banks and many others.

    Bluetooth is a new technology that utilises radio frequency waves as a way to communicate wirelessly between digital devices. It sets up personal area networks that incorporate all of a persons digital devices into one system for both convergence and convenience.

    Wireless- History

    Many people put the invention of [wireless] radio down to Guglielmo Marconi, who in 1895 sent the first radio telegraph transmission across the English Channel. Only twelve years later radio began being used in the public sphere. [Mathias, p.2] Up until then however, many wireless pioneers conducted trials across lakes where the antenna used to transmit the signal was longer than the distance across the lake. [Brodsky, p. 3] After its introduction the main use of wireless radio was for military communications where its first use was for the Boer War. [Flichy, p. 103] The invention of broadcast radio ensured the feasibility of wireless technologies. [Morrow, p. 2] By the 1920s, radio had become a well-recognised mass medium. [Flichy, p. 111] From the 1980s until now, wireless communications have been through several stages, from 1G (analogue signal), 2G (digital signal) and 3G (always on, faster data rate). [Lightman and Rojas, p. 3] The history of Bluetooth is a much more recent one, with the first Bluetooth-enabled products coming into existence in 2000. Named after Harald Blatand the first, king of Denmark around twelve hundred years ago, who joined the Danish and Norwegian kingdoms, Bluetooth technology is founded on this same unifying principle of being able to unite the computer and telecommunication industr[ies]. [Ganguli, p. 5] In 1994 the Ericsson Company began looking into the idea of replacing cables connecting accessories to mobile phones and computers with wireless links, and this became the main inspiration behind Bluetooth. [Morrow, p. 10]

    Wireless- Technologies

    Bluetooth is not the only wireless technology currently being developed and utilised. Other wireless technologies, including 802.11b, otherwise known as Wi-Fi, Infrared Data Association (IrDA), Ultra- Wideband Radio (UWB), and Home RF are being applied to similar technologies that Bluetooth use with mixed results. 802.11 is the most well known technology, excluding Bluetooth, and uses the same radio frequency, meaning that they are not compatible as they cause interference with each other. 802.11 is being implemented into universities in the US, Japan and China, as well as food and beverage shops where they are being used to identify students and customers. Even airports have taken up the 802.11 technology, with airports all over America, and three of Americas most prominent airlines promoting the use of it. [Lightman and Rojas, p. 202-3] Infrared Data Association is extremely inferior to that of Bluetooth. Its limitations include only being able to communicate point-to-point, needing a line of sight, and it has a speed of fifty- six kilobytes per second, whereas Bluetooth is one megabyte per second. [Ganguli, p. 17] The Ultra- Wideband Radio is superior to that of Bluetooth in that it can transmit at greater lengths (up to 70 metres), with only half of the power that Bluetooth uses. [Ganguli, p.17] HomeRF is a technology that is not very well known. It is used for data and voice communication and targeted for the residential market segment and does not serve enterprise- class WLANs, public access systems or fixed wireless Internet access. [Ganguli, p.17-18]

    Bluetooth- Technical Introduction

    Bluetooth is a short- range radio device that replaces cables with low power radio waves to connect electronic devices, whether they are portable or fixed. The Bluetooth device also uses frequency hopping to ensure a secure, quality link, and it uses ad hoc networks, meaning that it connects peer-to-peer. It can be operated worldwide and without a network because it uses the unlicensed Industrial- Scientific Medical (ISM) band for transmission that varies with a change in location. [Ganguli, p. 25-6] The Bluetooth user has the choice of point-to-point or point-to-multipoint links whereby communication can be held between two devices, or up to eight. [Ganguli, p. 96] When devices are communicating with each other they are known as piconets, and each device is designated as a master unit or slave unit, usually depending on who initiates the connection. However, both devices have the potential to be either a master or a slave. [Swaminatha and Elden, p. 49]

    Bluetooth- Advantages

    There are many advantages to using Bluetooth wireless technologies including the use of a radio frequency, the inexpensive cost of the device, replacing tedious cable connections, the low power use and implemented security measures. The use of an unlicensed radio frequency ensures that users do not need to gain a license in order to use it. Unlike Infrared which needs to have a line of sight in order to work, Bluetooth radio waves are omnidirectional and do not need a clear path. The device itself is relatively cheap and easy to use, one can be bought for around ten American dollars, and this price is currently decreasing. Compare this to the expensive cost of implementing hundreds of cables and wires into an office and there is no competition. Of course, this is the main reason for the take -up in Bluetooth -enabled devices; it does away with cables. Another of Bluetooths advantages is its low power use, ensuring that battery operated devices such as mobile phones and personal digital assistants wont have their battery life drained with the use of it. This low power consumption also guarantees minimal interruption from other radio operated and wireless devices that operate at a higher power. Bluetooth has several enabled security measures that ensures a level of privacy and security, including frequency hopping, whereby the device changes radio frequency sixteen hundred times per second. Also within the security tools are encryption and authentification mechanisms that guarantee little interference by unauthorised hackers. [Ganguli, p. 330] One of the best advantages of Bluetooth devices, especially the hands free device that connects to a mobile phone, is that it removes radiation from the brain region. [Tsang, p.1]

    Bluetooth- Applications

    The applications that are in development or current use for the Bluetooth technology include such areas as automotive, medical, industrial equipment, output equipment, digital -still cameras, computers, and communications systems. [Lightman and Rojas, p. 201] Bluetooth is an ad hoc network user, and therefore it may be used for social networking, i.e. people can meet and share files or link their Bluetooth devices together to play games or other such activities. [Smyth, p. 70] Using Bluetooth, a mobile phone can become a three- way phone, where at home it connects to a landline for cheaper calls, on the move it acts as a mobile phone and when it comes in contact with another Bluetooth-enabled phone it acts as a walkie- talkie. This walkie- talkie option allows for free interaction and communication, as Bluetooth is not connected to any telecommunications network. [Gupta, p.1] Bluetooth also allows automatic synchronization of your desktop, mobile computer, notebook and your mobile phone for the user to have all of their data managed as one. [Gupta, p.1]

    Bluetooth- Security Issues

    Bluetooth has several threats which range in level of risk and how widespread the action is. These threats have the ability to provide criminals with sensitive information on both corporate and personal levels. The only way to avoid such threats is for manufacturers, distributors, and consumers to be provided with more information on how they are committed, current attack activity and how to combat them. This information can be used on a technical level for manufacturers, it can be used by distributors at retail levels to teach consumers the risks and it can be used directly by consumers to be aware of the threats. The outcome of such research will allow end users of Bluetooth products to have an upper hand in this wireless warfare. Bluetooth security is in early stages with regards to both the attackers, their techniques and consumers understanding of these attacks. Some research has been conducted into what the attackers are doing and how they do it. Adam Laurie of A.L Digital Ltd is leading the research race in Bluetooth security and is often linked to academic resources. Laurie’s research has uncovered the following capabilities of Bluetooth attacks:

    • Confidential data such as the entire phone book, calender and the phone’s IMEI.
    • Complete memory contents of some mobile phones can be accessed by a previously trusted (“paired”) device that has since been removed from the trusted list.
    • Access can be gained to the AT command set of the device, giving full access to the higher level commands and channels, such as data, voice and messaging.

    Attacks on Bluetooth devices at this stage are relatively new to consumers, and therefore are not widely seen as a real threat. Attacks such as the Bluejack attack are probably more recognised by consumers due to its perceived humorous and novelty nature as well as the ease to Bluejack someone. Users who allow their phone to be Bluejacked open the door to more serious attacks, such as the Backdoor attack which have a low level of awareness amongst consumers as attackers can attach to the device with out the users knowledge. Corporations are starting to understand the risks Bluetooth devices pose, Michael Ciarochi (in Brewin 2004) stated that ‘Bluetooth radios were included in laptop PCs that were being configured by an IT Engineer. It raises the possibility of opening a wireless back door into data stored on the PCs. Such a security weakness would be extremely attractive to hackers. Although Bluetooth invites hackers to such attacks; Bluetooth Venders are playing down the risks, Brewin (2004) said that ‘Bluetooth advocates last week dismissed growing security fears about the short-range wireless technology, saying any flaws are limited to a few mobile-phone models. They also detailed steps that users can take to secure Bluetooth devices’. There are many methods of Bluetooth attacks, the Snarf, the Backdoor, Bluebug, Bluejack and Warnibbling attack are the only recognised attacks at this early stage. Below are explanations of such attacks.

    The SNARF attack

    It is possible for attackers to connect to the device without alerting the user, once in the system sensitive data can be retrieved, such as the phone book, business cards, images, messages and voice messages.

    Local Copy: BlueSnarf_CeBIT2004.pdf

    The BACKDOOR attack

    The backdoor attack is a higher concern for Bluetooth users; it allows attackers to establishing a trust relationship through the “pairing” mechanism, but ensuring that the user can not see the target’s register of paired devices. In doing this attackers have access to all the data on the device, as well as access to use the modem or internet; WAP and GPRS gateways may be accessed without the owner’s knowledge or consent.

    The BLUEBUG attack

    This attack gives access to the AT command set, in other words it allows the attacker to make premium priced phone calls, allows the use of SMS, or connection the internet. Attackers can not only use the device for such fraudulent exercises it also allows identity theft to impersonate the user.


    Dibble (2004) explained that ‘Just as SMS was spawned, there’s a new craze that’s spreading across parts of Europe. Reportedly, it’s more prominent in the UK, but popular elsewhere too’. Bluejacking allows attackers to send messages to strangers in public via Bluetooth. When the phones ‘pair’ the attacked can write a message to the user. Although it may seem harmless at first, there is a downside. Once connected the attacker may then have access to any data on the users Bluetooth device, which has obvious concerns. Powell (2004: 22) explained that ‘Users can refuse any incoming message or data, so Bluejackers change their username to a short barb or compliment to beat you to the punch. For example, you might receive something along the lines of “Incoming message from: Dude, you’ve been Bluejacked.” Or, “Incoming message from: ROI is overrated.” Bluejacking is regarded as a smaller threat to Bluetooth as users being attacked are aware they have been Bluejacked. This does not mean however that they are aware that sensitive information is being accessed and used in a malicious manner.


    Warnibbling is a hacking technique using Redfang, or similar software that allows hackers to reveal corporate or personal sensitive information. Redfang allows hackers to find Bluetooth devices in the area, once found, the software takes you through the process of accessing any data that is stored on that device. Redfang also allows non-discoverable devices to be found. Whitehouse explains when testing Redfang ‘One of the first obstacles we had to overcome was the discovery of non-discoverable devices (it was surprising to see the number of devices that dont by default implement this security measure)’.

    Future of Bluetooth

    Further information, and somewhat speculation is required for consumers and Bluetooth stakeholders on the future of Bluetooth. Such information will provide a clearer understanding of why security of Bluetooth must be improved. Luo and Lee (2004) provide a short term prediction of where Bluetooth is heading, Europe and Asian countries already offer electronic newspapers, subway tickets, and car parking fees via wireless devices. Collins (2003) says that Bluetooth devices ‘appear to be more secure than 802.11 wireless LANs. However, this situation may not last, as the Bluetooth technology becomes more widespread and attracts greater interest from the hacking community’.
