In the article, we mainly probe into various kinds of factors influencing the network coverage and adjust various kinds of wireless network parameter ,in odder to reach the best cover results .

Non-cooperative power control in wireless data networks;

This paper mainly studies channel assignment in wireless data network.

This paper presents a relative proportional fair scheduling scheme for wireless data networks, which not only adjusts system throughput by changing the scheduling parameters to guarantee system performance, but also guarantees fairness among different users and meets different QoS requirements for different users.

Analysing the influence of network parameters on the results predicted by modular algorithm;

Analysing the influence of network parameters on the forecast results of ANN;

Analysing the influence of network parameterson the forec ast results of ANN;

This method can also be used in predicting an- other GSM radio network parameter.

Practice prove that adjusting network parameter about handover can fleetly solves some difficult problems in network,and has obvious positive effect for network burthen and interferential electric level,and relax the congestion of call at cell area.
