What is a communications technology aimed at providing high speed wireless data over metropolitan area networks?

 

A Metropolitan Area Network (MAN) is an extensive computer network that covers a city or a large university campus. Its purpose is to provide a long-term link to the internet.

A MAN typically consists of several LANs connected to form a network. The backbone of this extensive network is made up of an optical fiber setup.

Communication Technologies with high-speed Networks in metropolitan areas:

Several technologies are commonly used to create a Metropolitan Area Network (MAN). These include FDDI (fiber distributed data interface), ATM (Asynchronous Transfer Mode), and SMDS (switched multi-megabit data service).

ATM is the most widely used of these technologies. It is a digital data transfer technology developed in 1980 to improve the transportation of real-time data over a single network. ATM works like a cell relay system, where data is divided into fixed, equal-sized packets and transmitted over time.

The primary purpose of ATM was to provide precise audio and video results during video conferencing. However, its attributes have made it the basis for wide-area data networking.

ATM combines the characteristics of circuit switching and packet switching, which allows it to transfer real-time data. FDDI is a standard for data transfer over a LAN that can be extended to approximately 200km.

It uses optical fiber as its basic infrastructure and can support the data transmission of many thousands of users, making it a suitable technology for a MAN. SMDS is a technology that transfers data through a connectionless service, stores data in the header, and reaches its destination independently through any network.

SMDS also forms small data packets, similar to ATMs, but allows the transmission of data over large geographical areas in the form of datagrams, which are data packets of an unreliable data service provider. MAN links can now be established using infrared and microwave signals

Conclusion

A high-speed wireless data network is a communications technology that provides high-speed wireless data over metropolitan area networks. It uses several technologies, including microwave frequencies and radio waves, to provide wireless communications services.
