Radio networks and wireless broadband attract us with the lack of wires and the speed of deployment. But, although most solutions based on 802.11 standards are good for deploying a network in a small office, they are not convenient for transmitting data over long distances and do not allow you to work (over long distances) in the absence of direct visibility. In addition, most of these solutions have serious security problems (if you use only the built-in encryption). Accordingly, such systems are poorly suited for service operators of wireless data transmission systems.
Currently, an increasing number of users are using wireless broadband access when connecting to the INTERNET / Intranet network. Given the convenience of wireless communications and the rapid development of the 802.11 protocol, interest in modern equipment that provides high-quality and fast wireless data exchange is growing significantly.
wireless broadband features:
Broadband companies own has all the necessary certificates and is widely used by both operators and public services, including public security organs.
The metal case allows you to have broadband wireless devices, combined with pre-tested radio components, various accessories and multifunctional software of our own design, allows you to build reliable wireless networks of varying complexity in almost all regions of our country, including regions of the far north with the most unpredictable weather conditions.
WORK PRINCIPLES of wireless broadband:
The principle of wireless broadband operation is via the base station radio channel (BS), it is possible to organize data transmission for several subscriber stations (AS) simultaneously. Moreover, the topology of such a network is called “point – many points”.
It is doable to restrain access to the BS to only one monitor. This topology is called point-to-point. To raise the range of the BS, repeaters are used. To cut out the electromagnetic rate of neer BS on each other, use spatial-frequency.
