In-Building Solution • • What is an In-Building Solution & Why is it required ? It is a process, where in we radiate adequate Mobile signals of one particular Network operator in that entire building. In places like basement floors, higher floors of some high rise Buildings, Airports, Corporate offices, Hotels & Shopping malls we tend to get signals from different cell sites around the building, so subscriber mobile ping-pong from one cell site to another resulting in high CALL-DROPS & High BER ( Rx Quality ) . | 12 13 2005 1 In-Building Solution What is an In-Building Solution Why is it required It is a process where in we radiate adequate Mobile signals of one particular Network operator in that entire building. In places like basement floors higher floors of some high rise Buildings Airports Corporate offices Hotels Shopping malls we tend to get signals from different cell sites around the building so subscriber mobile ping-pong from one cell site to another resulting in high CALL-DROPS High BER Rx Quality In some case when the subscriber base increases the Network operator has difficulty in planning new BTS. So instead of deploying a Macro Site the operator uses a Micro BTS where in the signal from Micro BTS will be distributed through out the building using Co-axial cables and distributed antenna system. By doing so we will have uniform signal been radiated all through out the building providing an error free Network connection to all their valuable subscribers present in that building. In the basement floors there will be absolutely no mobile signals present so this problem also can be solved using a distributed antenna system in that floor. Network Problems inside Buildings High Call Drops - Above 4th or 5th floors Due to Multi cell Hand over High Bit Error Rate - Due to Multipath propagation Water refraction Interference from other cell sites of same operator or other operators No network Coverage - Basements Ground Floors etc. Penetration loss UD t I Subscriber base increases - If deployment of new BTS sites are not possible P II J j Al 12 13 2005 2 Topics 1.
