Wireless local loop

from Wikipedia, the free encyclopedia

The wireless local loop technology ( WLL ) is used where the telephone connection via a subscriber line (local loop) is not feasible or too expensive, e.g. B. in sparsely populated rural areas. New network operators who do not have a copper access network are also using this technology.

There are two different procedures:

The WLL technology requires licensing of the radio frequencies used. WLL is used as a technology for broadband services (comparable to DSL and cable television), although from a technical point of view it can also be used exclusively for telephony. In combination with an alternative, terrestrial backup line, WLL is ideal for a particularly fail-safe connection to the Internet. Under the name WiMAX several were IEEE - standards for wireless local loop radio networks together.

As alternatives to fixed wireless connection of subscribers with rather low traffic volume also are GSM - mobile voice connections and data transmission on 3G mobile radio standards such as UMTS and HSDPA -based connections with cellular gateways as a stationary network termination possible.
