A review of TEC standard No.G/WLL-01/02 October '97 for digital wireless local loop system

Abstract

The uptrend in the use of digital wireless communication system is well justified taking into account its inherent advantages. The Telecommunication Engineering Centre (TEC) has brought out a standard No.G/WLL-01/02 October 1997 on Digital Wireless Local Loop (WLL) system to provide two way communication for Department of Telecommunication (DoT) Customer Access Network. This standard lists the complete requirements the WLL system has to qualify. Electromagnetic compatibility (EMC) is one of the requirements. This paper presents a critical review of the EMC aspects of this standard. It describes the various electromagnetic disturbance phenomenon the WLL system is likely to encounter in the working environment. It suggests the other appropriate tests that need to be considered for inclusion in this standard.
