Wi-Fi quality & coverage

How good is call quality on Wi-Fi?
Call quality is better on Wi-Fi than 3G Networks. 3G Networks top out at less than 500 kbps (kilobits per second) and thus can’t compare with Wi-Fi technology that blazes at speeds of up to 54 mbps (megabits per second).

What about Wi-Fi coverage?
Wi-Fi signals are short range coverage frequencies. In high density populations most restaurants, hospitals, airports, hotels, schools, colleges, universities, stores and shopping centers all have free Wi-Fi Hotspots. The advantage is low cost GLOBAL MOBILITY without roaming charges.
