Wireless Security Protocols - Prevention of unauthorized access or damage to computers using wireless security. Take a school for example. Schools use Sophos software that monitors the computers usage and it also blocks any unwanted viruses that could potentially harm the computers. It has protocols like WEP, which is short for Wired Equivalent Privacy. This provides the same level of security as wired networks. There is also WPA, which stands for Wi-Fi Protected Access and this was introduced as an interim security enhancement whilst they were working on something else. Last but not least, there is WPA 2, which is basically Wi-Fi Protected Access Version 2. This is used by U.S Government for them to be able to encrypt information.

With Bluetooth, there are quite a few protocols that Bluetooth has and some of them I will happily explain. There is the Link Management Protocol that controls the link between two devices and handling matters like link establishment. There is also the Bluetooth Network Encapsulation Protocol (BNEP). This protocol is used by Personal Area Networks (PAN).

802.11802.11 - Applies to wireless LAN's and can use transmissions over small lengths. This uses a specific Ethernet Protocol and does happen to use CSMA/CA, which stands for Carner Sense Multiple Access with Collision Avoidance. This CSMA/CA is used to create a path for sharing. Previous models of 802.11 would have a phase shift key (PSK) but now it has a complementary code keying (CCK).

GSM/UMTS - UMTS stands for Universal Mobile Telecommunications System and this is based on a GSM standard. Here are some protocols that belong to the UMTS family. AMR, which is known as Adaptive Multi-Rate. This is basically a speech decoder that works for devices that have 3G (Third Generation) in them. The BCC is known as the Broadcast Call Control, which can be used by a video group voice chat or as some like to call it, a video conference. The BMC is the Broadcast Multicast Control, this can store Cell Broadcast Messages and can schedule BMC messages.
