The narrowband antennas do not use satellites. To deliver wireless broadband Internet, a combination of technology platforms are used, from fixed wireless for the first mile connection to fiber rings that connect hub site buildings, to long-haul fiber that connects cities. Wireless broadband connections and other fixed-wireless connections deliver data rates from T1 to 155 Mbps. These wireless connections serve the same function as a wireline, interconnecting private networks, bypassing a local exchange carrier, or connecting to the Internet. When a user sends data, data packets stream to an antenna.
Data going from the backbone to the customer is received at the hub.
The hub sorts the packets and distributes them as transmissions aimed at the rooftop antennas on surrounding buildings. From support of a SOHO to advanced video teleconferencing, there are many potential uses for DSL and other broadband applications. Although DSL and other broadband technologies offer greater data access rates at a relatively low cost per user, drawbacks to broadband access also exist. The system is not portable and is difficult to install. Broadband is not ubiquitous and may be expensive for small numbers of users.
