Cellular system planning is either coverage of capacity driven.
Initially, an operator attempts to cover the service area as good as possible
with only a limited number of base stations. His main concern is that
the signal-to-noise ratio is sufficient at each location.
The link budget is a kind of "balance sheet" to select
the system parameters
Interference is not yet limiting the system performance.
In a latter phase when more subscribers are using the system,
the operator typically attempts to improve capacity by adding more base stations. The grid of base stations becomes denser and signal-to-noise ratio
is no longer limiting the performance. Co-channel and adjacent channel interference become more of concern.
GSM link budget calculator
This page allows you to calculate the link budget for a the uplink in a GSM (or GSM-like) network.
Pathloss is computed using the Egli model.
Default system parameter are similar to the GSM specs, however, we choose
a handheld used indoor with a cell radius of 30 km. Typically, GSM
only covers handheld indoor subscriber that are quite close to the base station.
