In 1997 over 31% of all wireless local loop systems used DECT technology. Details of wireless local loop deployments of DECT WLL systems may be found elsewhere on this website - see Global DECT - and in the DECT Forum article on this topic.

A good article on CTM may be found in the March 1998 DECT Forum Newsletter

KY-DWLL DECT WLL system.
This system comprises 4 elements - Radio Control Module (RCM), Radio Port Controller (RPC), Radio Port (RP) and Radio Terminal (RT). The Radio Control Module is the heart of the system. It controls all of sub-modules. The Radio Port Controller is for DIC interface card used to control the Radio Ports. The Radio Ports may be used is indoor and outdoors. Radio terminals provide the telephone function.

System capacity
This system can provide Max 4 RPC modules, with each RPC module providing 15 U interface as 4 DIC interface cards. Therefore, each DIC interface card has 4 U interfaces. The maximum capacity is 2880 Radio Terminal Users.

DECTxs system - private wallset, public and private systems based on the corDECT technology developed by IIT Chennai.

In an urban deployment of DECTxs, subscribers can be served using microcellular architecture(cell size 300 to 1000 metres). For high density business centres, multiple Base Stations can be stacked together.

In the case of suburban areas, medium sized cells (1km - 3.5kms) can be used. As suburban areas are prone to the growth of subscribers in either a planned or an unplanned manner, such requirements can be easily dealt with by adding Base Stations on a as and when required basis, as the system does not require any frequency planning.

Remote Semi - Urban/Rural Coverage
For remote semi-urban and rural areas where the existing demand does not call for an independent BSC, Base Stations can be located remotely using an El interface links. Moreover, with the extended range Wall Sets, the DECTxs coverage may be extended to 8-10 kms from the BS location.

Thin Route, Distributed Rural Coverage
Where the operator is required to provide between 25 to 100 lines for spot coverage in remote clusters or townships, DECTxs provides the most cost-effective solution. In this case Base Stations can be located at every 20-50 kms using an El drop insert backbone. DECTxs optimises the immediate exposure to the operator

Key features of DECTxs
Affordability, low up-front investment
Very fast & easy deployment
Adaptability to very high & low subscriber densities
Toll quality 32 kbps ADPCM voice
Enhanced privacy/Data, fax, payphone support
Modular & adjustable system architecture
No frequency planning required
Futurability - ISDN, Video-conferencing etc.
Spectrum sharing using DCS to allow a multi-operator, multiple BSC environment in the same 20 MHz band
Centralised NMS
