Networks — Wi-Fi coverage area — Grand Poitiers Business data

The data represents the theoretical coverage area of the wifi service. It is stated that this is not the result of a radio study but an empirical test: there is no question of a level of coverage and it is possible that the service is accessible outside the theoretical coverage area and some shadow areas remain within it.本数据集表征WiFi服务的理论覆盖范围。需说明，该数据并非源自无线电勘测，而是基于经验测试所得：覆盖等级并无明确界定，服务有可能在理论覆盖范围之外仍可被访问，且理论覆盖范围内亦存在部分阴影盲区。
