Broadband data service

Both 3G and WiFi support broadband data service, although as noted earlier, the data rate offered by WiFi (11Mbps) is substantially higher than the couple of 100 Kbps expected from 3G services. Although future generations of wireless mobile technology will support higher speeds, this will also be the case for WLANs, and neither will be likely to compete with wireline15 speeds (except over quite short distances).

The key is that both will offer sufficient bandwidth to support a comparable array of services, including real-time voice, data, and streaming media, that are not currently easily supported over narrowband wireline services. (Of course, the quality of these services will be quite different as will be discussed further below.) In this sense,16 both will support "broadband" where we define this as "faster than what we had before."

Both services will also support "always on" connectivity which is another very important aspect of broadband service. Indeed, some analysts believe this is even more important than the raw throughput supported.
