Introduction
corDECT is an advanced, field proven, Wireless Access System developed by Midas Communication Technologies and the Indian Institute of Technology, Madras, in association with Analog Devices Inc., USA
corDECT provides a complete wireless access solution for new and expanding telecommunication networks with seamless integration of both voice and Internet services.
The Technology
Based on the Digital Enhanced Cordless Telecommunication (DECT) Standard
Based on a micro cellular architecture
corDECT micro cell could be as small as 250-meters.
SUB-SYSTEMS OF CorDECT
Wallset IP
Wallset with Internet Port (WS-IP) provides voice connectivity to the subscriber using a RJ-11 interface.WS-IP can support simultaneous voice and 35 kbps Internet connections.
Multiwallset IP
The Multiwallset with Internet Port (MWS-IP) is a MWS with four telephones and an additional Ethernet interface to provide dial-up Internet connectivity.
Multiple PC’s can be connected to the port and provide a shared 35/70 kbps Internet connection
Compact Base Station
The CBS is a small, pole-mounted or wall-mounted electronic unit that provides 12 simultaneous speech channels.
It provides interface between DIU and subscriber terminal.
Each line can carry four speech channels and one channel of 16kbps signaling
DECT Interface Unit
Authentication is the process by which a corDECT subscriber terminal is positively verified as belonging to a legal subscriber of a particular DIU.
Authentication involves an Authentication Key which is never transmitted on air. The keys are maintained securely in the system and are inaccessible to anyone.
Subscription
Subscription is the process by which a subscriber is added/deleted from the system and the features the subscriber desires to have are enabled.
It is also the process by which the system formally transfers the identity, such as subscriber number, to the Wallset.
Advantages
Eliminates the physical connections between telephone exchanges and subscribers
Has a simple technology structure, easier to implement, supports large number of subscribers
Costs less than traditional Wireless Structure used by Mobile Operators
Conclusion
The corDECT wireless local loop system offers relatively low cost and rapid installation of telecom services in areas with even high subscriber density environments.
Good Market in developing Countries like India, Russia, China etc.
Good for highly dense urban areas.
