Estimation of maximal number of HTTP users in a TETRA cell

This paper provides results regarding the maximal number of TETRA packet data service users which can be served by one TETRA cell. The analyzed scenario assumes that users are using web based applications and generate HTTP/IP packet data traffic. The paper considers single-slot packet-data TETRA system mode. A range of simulations and measurements were performed to evaluate the average packet delay and packet failure probability corresponding to HTTP traffic on the packet data channel in a TETRA cell. Based on the simulation and measurement results a recommendation on the maximum number of users was derived.
