37.705 is a protocol, or set of standards, designed for wireless local-area networks (WLANs) based on the IEEE 802.11 standard. It is an amendment to IEEE Standard 802.11b-1999 with a throughput of up to 54Mbps. It was ratified as IEEE Standard 802.11g-2003. This protocol is widely used for wireless internet access in commercial, residential, and public hotspot applications, as well as for data communications over short distances. The significant improvements from the older 802.11b standard are higher rates of data transfer and a larger area of coverage with fewer antennas, enabling a higher population density of users.

The main application fields of 37.705 are high-speed communications over distances of up to 100 meters, both indoors and outdoors, as well as in urban, suburban, and rural areas. It is well suited for applications such as Voice over Internet Protocol (VoIP), streaming media, video conferencing, and file sharing, and can support large scale video surveillance networks. It is popular in home and office networks and is often used in public hotspots.

The working principle of 37.705 is based on the “carrier sense multiple access/collision avoidance” (CSMA/CA) approach. This means that when a device wants to send a packet of data, it senses the wireless medium to determine if it’s available, and if it is, it transmits a request for access. All other devices then stop transmitting and wait for a response from the intended recipient. If the recipient grants access, the data is transmitted. This process involves the exchange of control frames, which protect against collisions and interference from other wireless networks in the area.

37.705 also uses multiple operating channels so that more than one device can access the network at any given time. The protocol includes a medium access control (MAC) layer that allows for efficient data transmission between the wireless nodes and the devices. The MAC layer also ensures that the packet data is received in a timely manner and that no data is lost due to collisions.

In addition, the protocol utilizes an adaptive modulation scheme that can dynamically change the characteristics of the signal according to the conditions of the radio medium. This allows for reliable data transmission at the highest possible data rates in any given environment. Finally, the protocol supports authentication, encryption, and other security measures to ensure the privacy of transmitted data.

37.705 is a powerful and reliable wireless networking protocol that is widely used for a variety of applications. Its combination of performance, range, reliability, and scalability make it an ideal choice for both outdoor and indoor wireless networks.
