Network acceptance In building Planning: |
|
Indoor coverage is a
major differentiator in the competitive
environment. Dedicated In-building Coverage
solutions require careful planning to ensure
adequate coverage and also to ensure that the
traffic is carried through the dedicated
solution. Even in the case of repeaters, proper
gain settings are required to ensure optimum
performance and to avoid Oscillations. The work
involves: |
| |
Walktest to
understand the propagation environment
Planning for RF distribution network
Selection of suitable locations for installation
of Antennas
Cable route survey and measurements
Documentation for submission to Building
authorities
Post installation acceptance testing for
verification of coverage
Recommendation on BSS parameters for desired
Handover behavior |
|
