Wireless Access Network GSM network optimization

structures. to compete in the market, network optimization becomes more important. I. Scope of Network Optimization Network optimization is a high-level maintenance task. It uses new technologies and optimization tools to rationally adjust network parameters and network resources to improve network quality. Indoor distribution, frequency hopping, concentric circles, DTX, and power control can be used to reduce interference, increase network capacity,

On the Necessity of wireless communication network optimization

Invisible wireless networks are quietly laid around us, bringing more convenience to our lives. The mobile phones that everyone can't leave are also transmitted through wireless networks. As a result, more mobile phone users are under increasing network pressure. Therefore, it is particularly important to optimize the wireless communication network. Wireless communication network optimization is the key to improving network service quality and an important way to enhance network competitiveness.
