corDECT Wireless Access System

Following the conceptual model, the corDECT Wireless Access System uses a similar architecture to provide telephone and Internet service to a subscriber, as shown The subscriber premises equipment, Wallset IP (WS-IP)

could also incorporate switching maintenance functions when required. Further, is possible to co-locate lnternet servers with Ea AC.

The subscriber premises equipment, Wallset IP (WS-IP) or Wallset (WS), bias a wireiess Connection through a Compact Base Station CBS) to an Access Switch, called a DECT Interface Unit (DIU). The air interface is compliant c) the DECT standard specified by ETSI. The )IU switches the voice traffic to the telephone I network using the V5.2 protocol to connect to in exchange. The DIU also switches the Internet built-in Remote Access Switch(which then routes the traffic to the Int network. The Ras has an Ethernet into which is connected to the Internet using suitable routing device.

The CBS is normally connected to the DIU three twisted-pair wires, which carry sign well as power from the DIU to the Alternatively, it can be connected to through a Base Station Distributor (BSD BSD is remote unit connected to the DIU a standard E1 interface ( on radio, fibre, A BSD can sup to four CBS’s.

The long range communication, a WS is can also be connected to the CBS using hop DECT wireless link, one between V WS and a Relay Base Station (RBS) and between the RBS and CBS, The wireless range supported be WS 0 Ip or WS and the CBS or RBS is

line-of-Sight (LOS)'conditions. The range supported between a CBS and RBS is 25 km in LOS conditions. 

A typical system consists of one DIU with one or two RAS units, up to 20 CBS'S, and up to a 1 000 WS-IP's or WS's. The BSD and RBS units are used as required by the deployment scenario.
