Editing Wireless network (section)

=== Wireless WAN ===
[[Wireless wide area network]]s are wireless networks that typically cover large areas, such as between neighboring towns and cities, or city and suburb. These networks can be used to connect branch offices of business or as a public Internet access system. The wireless connections between access points are usually [[Point-to-point (telecommunications)|point to point]] [[Microwave transmission|microwave links]] using [[parabolic dish]]es on the 2.4&nbsp;GHz and 5.8&nbsp;GHz band, rather than [[omnidirectional antenna]]s used with smaller networks. A typical system contains base station gateways, access points and wireless bridging relays. Other configurations are mesh systems where each access point acts as a relay also. When combined with renewable energy systems such as photovoltaic solar panels or wind systems they can be stand-alone systems.
