INTRODUCTION

WLL is a system that connects subscribers to - the local telephone station wirelessly.

.

The telephone must support fax and modem communications .

Ability to provide atleast medium rate Internet access is a must. The traffic supported should be reasonably high. Ability to support a large number of subscribers in an urban area . Cost of providing this wireless access should be less than that required for wired telephone.

Wireless in Local Loop (WiLL) is meant to serve subscribers at homes or offices.

The telephone provided must be atleast as good as wired phone. Its voice quality must be high

HISTORY

• Till around mid 80s' in India, a local loop or an Access Network (AN) used to consist of a pair of copper wires connecting the subscribers at home or office to the nearest exchange.

• The local loop length in urban areas would be typically as large as 6 to 8 kms and the copper gauge used was 0.5 mm to 0.6 mm.

• The loop was designed to carry 4 kHz voice and was difficult to maintain, with almost 85% of all faults found in the local loop.

• Above all, it was expensive, difficult, and time-consuming to deploy. With the rising cost of copper and cost of digging increasing every year, if one had continued with such an approach, the per line local loop cost itself would have been Rs.40,000 to Rs.50,000 and would have amounted to over 85% of the total cost of putting a telecom network.

A WLL (Wireless Local Loop) is a radio access system for users to access PSTN (Public Switched Telephone N/w).It is a substitute for conventional wired access. The GSM-WLL system makes use of GSM technologies to achieve WLL.A GSM-WLL system is composed of GSM system equipment and GSM wireless terminals.

Global System for Mobile Communications, GSM is a digital cellular communications system.

GSM is designed to provide a comprehensive range of services and features to the users not available on analogue cellular network.

GSM

CDMA

Code Division Multiple Access (CDMA) is a multiple access technology where the users are separated by unique codes, which means that all users can use the same frequency and transmit at the same time.

WLL shall facilitate cordless telephony for residential as well as commercial complexes where people are highly mobile. It is also used in remote areas where it is uneconomical to lay cables and for rapid development of telephone services. The technology employed shall depend upon various radio access techniques, like CDMA.

WLL SETUP

SITUATIONS MADE FOR WLL

• Environments where 3rd line is degraded might be cheaper to go wireless• Where it’s impossible to lay copper (3rd world, small islands)• Business parks, industrial areas• Speedy deployment, stop gap application till wireline is in 90-120 days for activation
