Contrast Analysis of Mine-used Technologies of TD-SCDMA and WiFi

A brief introduction of technologies of TD-SCDMA and WiFi was given. Combined with demand of coal industry applications, performances of technologies of TD-SCDMA and WiFi were compared and analyzed from aspects of wireless link budget, voice quality, system capacity, switch quality, power control and applicability of the technologies in coal mine. And the results showed that TD-SCDMA technology was more suitable for mine communication system.
