Definition: WISP


(Wireless ISP) An Internet service provider (ISP) that transmits wireless. Using Wi-Fi or other radio frequencies licensed by the government, WISPs provide "last mile" connectivity directly to homes and businesses.

Mobile Wireless
Carriers such as AT&T and Verizon are technically "mobile WISPs;" however, they are generally called "cellular carriers" or "mobile carriers."

Fixed Wireless
In contrast, "fixed wireless WISPs" mount antennas on tall buildings with line of sight to their customers or to other antennas that relay the signals around obstacles. WISPs became popular in rural and outlying areas, because they were the only high-speed Internet connection available; however, they are also deployed in urban areas and compete with the major ISPs.

A Backup Option
Companies use WISPs for regular Internet access as well as for backup in case their wired connection fails. See WiMAX, ISP, fixed wireless, Clearwire, WISPr and 802.11.
