INTRODUCTION
WLL is a system that connects subscribers
to - the local telephone station wirelessly.
.
 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
 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.
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.
GSM
 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.
 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.
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
