In January 2005, a mobile malware worm known as Lasco surfaced. The worm began targeting mobile phones using Symbian OS ” rel=”nofollow”> Series 60 platform) using Bluetooth enabled devices to replicate itself and spread to other devices. The worm is self-installing and begins once the mobile user approves the transfer of the file from another device. Once installed, the worm begins looking for other Bluetooth enabled devices to infect. Additionally, the worm infects other .SIS files on the device, allowing replication to another device through the use of removable media . The worm can render the mobile device unstable.

In April 2005, Cambridge University security researchers published results of their actual implementation of passive attacks against the PIN-based pairing between commercial Bluetooth devices. They confirmed that attacks are practicably fast, and the Bluetooth symmetric key establishment method is vulnerable. To rectify this vulnerability, they designed an implementation that showed that stronger, asymmetric key establishment is feasible for certain classes of devices, such as mobile phones.

In August 2005, police in Cambridgeshire, England, issued warnings about thieves using Bluetooth enabled phones to track other devices left in cars. Police are advising users to ensure that any mobile networking connections are de-activated if laptops and other devices are left in this way.

How Do Wifi Signal Boosters Work

Keep in mind that the WiFi signal booster needs to be connected to a cellular modem for it to work. The kits come with four main components: the outside antenna, the amplifier/repeater, a pole mount, and cable.

  • The outside antenna will be mounted on the pole mount and it will capture the existing cellular signal outside.
  • The existing outside signal is converted and sent to the amplifier/repeater. The amplifier is used to boost the signal that is being received from the outside antenna.
  • The boosted signal is passed on to the modem which releases the radio waves into the area you need it for faster and better internet speeds.
  • Putting It All Together

    Keeping the scenario above, lets say you want to send a photo via email to your friend, how does the process work?

    Once your computer has established Wi-Fi connection from communication between your broadband modem, router and computer you can sign on to your email account, attach the photo you want to share, and hit send.

    Then through a combination of TCP/IP and 802.11 networking specifications, your data will be broken into tiny packets of binary code . These tiny packets are sent like Morse code via radio waves.

    Because there are so many radio waves flowing through the air, Wi-Fi is transmitted at two different frequencies based on packet size to minimize interference:

    Securing Your Wireless Network

    Security is always important with a wireless network, it’s even more important because your network’s signal could be broadcast outside your home. If you don’t help secure your network, people with PCs nearby could access info stored on your network PCs and use your Internet connection.

    To help make your network more secure:

    Change the default user name and password. This helps protect your router. Most router manufacturers have a default user name and password on the router and a default network name . Someone could use this info to access your router without you knowing it. To help avoid that, change the default user name and password for your router. See the documentation for your device for instructions.

    Set up a security key for your network. Wireless networks have a network security key to help protect them from unauthorized access. We recommend using Wi-Fi Protected Access 2 security if your router supports it. See the documentation for your router for more detailed info, including what type of security is supported and how to set it up.

    Some routers support Wi-Fi Protected Setup . If your router supports WPS and its connected to the network, follow these steps to set up a network security key:

  • Do one of the following, depending on which version of Windows is running on your PC:

  • In Windows 7 or Windows 8.1, select Start, start typing Network and Sharing Center, and then choose it in the list.

  • Select Set up a new connection or network.

  • Beyond Computers And Routers

    Is Wifi Direct Supported On My Windows 10 Pc

    WiFi Direct is supported on Windows 10 IoT Core devices through the use of a WiFi Direct enabled USB WiFi adapter. To make sure that WiFi Direct is enabled two things need to happen:

  • The hardware of the USB WiFi adapter has to support WiFi Direct, and
  • The corresponding driver of the USB WiFi adapter needs to support WiFi Direct.
  • WiFi Direct offers a service for WiFi device-to-device connection that doesnt require a Wireless Access Point to set up the connection.

    WiFi Direct on Windows 10 lets users experience the same WiFi connectivity that many other devices are using. With it, you can connect your computer to the TV, or use it for internet connectivity with much better security. In fact, WiFi Direct lets you connect to any other device with your PC much better and easier than even Bluetooth.

    What Are The Benefits Of Wifi Calling

    WiFi calling allows you to call or text from any location with a WiFi connection. This can be a major benefit especially if you are in an area that a cellular network doesnt reach. So, what are the advantages of WiFi calling?

    • Improves voice quality in areas where network coverage is weak
    • Incurs no additional charges WiFi calls inside the U.S. and to the U.S. are typically included in your monthly voice plan
    • Requires no add-on services and special plans calls may count toward your minutes unless your plan is unlimited
    • Needs no separate applications the feature is built into most devices
    • Uses your existing phone number no additional logins are necessary
    • Extends battery life the constant search for cellular networks can drain your smartphones battery

    In addition, WiFi calling doesnt require a lot of bandwidth. Typically, a voice call uses approximately 1 MB per minute and a video call uses between 6-8 MB per minute. For all of these reasons, it could make sense to take advantage of solid WiFi coverage when its available.

    What Are The Advantages Of Wi

    One key advantage of having Wi-Fi enabled devices is that they will allow you to connect to other Local Area Networks when you are out and about, as well as to your home network. Whilst many phones will allow connection to the internet through the phone signal, this can be patchy, and sometimes costly depending on your phone tariff.

    When travelling abroad outside Europe, for example, the ability to use a local LAN for free can be preferable to paying roaming charges for internet connection via a phone network though of course some networks such as Three let you use your mobile data in many destinations at no extra cost.

    Many cafes and shops have established their own WLANS which are often free to use you may need to enter a password when you first try to connect, but this password is usually simple and displayed widely around the premises. You may not get as fast a connection as you get at home, as many people may be sharing the connection simultaneously, but the service should be good enough for general browsing.

    What Is A Wireless Usb Adapter Used For

    Bluetooth vs WiFi – What’s the difference?

    A wireless USB adapter connects a computer without wireless hardware to a wireless network by transmitting either a Wi-Fi or Bluetooth signal. Installing the adapter requires plugging it into a USB port on a computer and installing drivers and other software if necessary. Once the adapter is installed, a wireless connection can be established.

    Unlike broadband and satellite USB modems, which require special SIM cards and dedicated service providers, wireless USB adapters can connect computers to wireless networks without additional tools or service expenses. Those with older computers that do not have wireless cards can purchase a card for a relatively low price. Doing so is much less expensive and more convenient that buying an internal adapter, and these cards are just as efficient when it comes to accessing free Internet services offered at public libraries, coffee shops and more.

    Installing USB wireless adapters has gotten easier because the Windows and Apple operating systems now include driver software from many equipment manufacturers that recognize a wide range of USB adapters. Microsoft also provides its own generic drivers, so if a branded driver is not listed for a certain computer during the installation process, Microsofts driver software can probably support it.

    Influence On Developing Countries

    Over half the world does not have access to the internet, prominently rural areas in developing nations. Technology that has been implemented in more developed nations is often costly and low energy efficient. This has led to developing nations using more low-tech networks, frequently implementing renewable power sources that can solely be maintained through solar power, creating a network that is resistant to disruptions such as power outages. For instance, in 2007 a 450 km network between Cabo Pantoja and Iquitos in Peru was erected in which all equipment is powered only by solar panels. These long-range Wi-Fi networks have two main uses: offer internet access to populations in isolated villages, and to provide healthcare to isolated communities. In the case of the aforementioned example, it connects the central hospital in Iquitos to 15 medical outposts which are intended for remote diagnosis.
