Wireless Protocols

Wireless Protocols As with all data transmission technologies, protocol management information is transmitted between stations. This protocol is only an agreed upon standard and is used by all parties to allow various devices to communicate with each other. Wireless protocols can be discussed separately or in the OSI protocol suite. For clarity, we intend to limit our discussion to wireless network implementation. Wireless protocols are usually located in the first and second layers of the OSI model, the application layer and the presentation layer.

As the use of low-power wireless protocols continues to increase, you can imagine wireless devices such as wireless keyboards, powerpoint presenters, mobile phone headsets, health monitoring sensors, and so on all over the place. However, due to the overlap of physical frequencies, the unevenness of these devices results in increased interference and congestion between the network and the network. Cognitive radio and multi-frequency MAC are some of the methods developed for parallel communication using multiple frequencies. SAS provides a versatile solution: Adaptive spectrum management middleware for wireless sensor networks that easily integrates with existing single frequency

Wireless APs are not secure regardless of whether encryption is used or not. Protocols such as wireless encryption protocols contain known vulnerabilities that are vulnerable to attack frameworks such as Aircrack. More powerful protocols such as Wireless Protect Access (WPA) and WPA 2 are still vulnerable to dictionary attacks unless strong keys are used. Solution: It is recommended that you use RADIUS and WPA2 Enterprise, and APs that can perform authentication and security measures. It is necessary to change frequently using passwords with mixed strong passwords. Normally, wireless APs are connected for convenience, so it is not usually necessary to connect to the working environment.

The basic security profile of WiFi is Wireless Equivalent Privacy (WEP) protocol based on RC4 stream cipher. The WEP protocol proved to be unsafe. Instead, the WiFi Alliance defines Wireless Protected Access (WPA). The next version like WPA 2 uses AES instead of RC 4 and strong authentication protocol EAP - TLS. Bluetooth technology is based on the IEEE 802.15.1 standard for short-range wireless communication between fixed devices and mobile devices in PANs based on low cost transceiver microchips within each device. You can also share a crowded spectrum with other technologies in the 2.4 GHz band. Supports 3 Mbps data rate and 24 Mbps v 3.0

Wikipedia was accessed from mobile phones via Wapedia service as early as 2004 through Wireless Application Protocol (WAP). In June 2007, Wikipedia launched the official website for wireless devices, en.mobile.wikipedia.org. In 2009, a new mobile service was officially launched at en.m.wikipedia.org to accommodate more advanced mobile devices such as iPhone, Android based device, WebOS based device etc. Several other methods of mobile access to Wikipedia are also appearing. Many devices and applications optimize or enhance the display of Wikipedia content for mobile devices, but some devices and applications use Wikipedia metadata such as geographic information (see Wikipedia: Metadata) etc. Other functions are also included.
