A wireless Internet service provider (WISP) is an Internet service provider with a network based on wireless networking. Technology may include commonplace Wi-Fi wireless mesh networking, or proprietary equipment designed to operate over open 900 MHz, 2.4 GHz, 4.9, 5, 24, and 60 GHz bands or licensed frequencies in the UHF band (including the MMDS frequency band), LMDS, and other bands from 6Ghz to 80Ghz.

In the US, the Federal Communications Commission (FCC) released Report and Order, FCC 05-56 in 2005 that revised the FCC’s rules to open the 3650 MHz band for terrestrial wireless broadband operations.[1] On November 14, 2007 the Commission released Public Notice (DA 07-4605) in which the Wireless Telecommunications Bureau announced the start date for licensing and registration process for the 3650-3700 MHz band.[2]

As of July 2015, there are over 1,280 fixed wireless broadband providers operating in the US covering 51% of the US population.[3][4]

History

Initially, WISPs were only found in rural areas not covered by cable or DSL.[5] The first WISP in the world was LARIAT, a non-profit rural telecommunications cooperative founded in 1992 in Laramie, Wyoming. LARIAT originally used WaveLAN equipment, manufactured by the NCR Corporation, which operated on the 900 MHz unlicensed radio band. LARIAT was taken private in 2003 and continues to exist as a for-profit wireless ISP.

Another early WISP was a company called Internet Office Parks in Johannesburg, South Africa that was founded by Roy Pater, Brett Airey and Attila Barath in January 1996 when they realized the South African Telco, Telkom could not keep up with the demand for dedicated Internet links for business use. Using what was one of the first wireless LAN products available for wireless barcode scanning in stores, called Aironet (now owned by Cisco), they worked out if they ran a dedicated Telco link into the highest building in a business area or CBD they could wirelessly "cable" up all the other buildings back to this main point and would only require one link from the Telco to connect up hundreds of businesses at the same time. In turn each "satellite" building was wired up with Ethernet so each business connected into the Ethernet LAN could instantly get Internet access. Due to the immaturity of wireless technology, security issues and being forced constantly by Telkom SA (Then the government Telco in South Africa) to cease its service, the company closed its doors in Jan 1999.

In 2009, a company called Cosmos Wireless founded by William Demetriou, set up their own network in the Republic of Cyprus, after realizing that no one could get internet if they lived in rural areas. During the following years, Cosmos Wireless' founder realized that even people who lived in towns and commercial areas also wanted this service. The company grew to a point where Cosmos Wireless is now able to cover the whole island, making Cosmos Wireless the first WISP to cover an entire country.

There were 879 Wi-Fi based WISPs in the Czech Republic as of May 2008,[6][7] making it the country with most Wi-Fi access points in the whole EU.[8][9] The providing of wireless Internet has a big potential of lowering the "digital gap" or "Internet gap" in the developing countries. Geekcorps actively help in Africa with among others wireless network building. An example of a typical WISP system is such as the one deployed by Gaiacom Wireless Networks which is based on Wi-Fi standards. The One Laptop per Child project strongly relies on good Internet connectivity, which can most likely be provided in rural areas only with satellite or wireless network Internet access.

Overview

WISPs often offer additional services like location-based content, Virtual Private Networking and Voice over IP. Isolated municipal ISPs and larger statewide initiatives alike are tightly focused on wireless networking.

WISPs have a large market share in rural environments where cable and digital subscriber lines are not available; further, with technology available, they can meet or beat speeds of legacy cable and telephone systems.[10] In urban environments, Gigabit Wireless links are common and provide levels of bandwidth previously only available through expensive fiber optic connections.[11]

Typically, the way that a WISP operates is to order a fiber circuit to the center of the area they wish to serve. From there, the WISP will start building backhauls (gigabit wireless or fiber) to elevated points in the region, such as a radio towers, tall buildings, grain silos, or water tower. Those locations will have access points to provide service to individual customers or to provide backhauls to other towers where they have more equipment. The WISP may also use gigabit wireless links to connect a PoP (Point of Presence) to several towers, reducing the need to pay for fiber circuits to the tower. For fixed wireless connections, a small dish or antenna is mounted to the roof of the customer's building and aligned to the WISP's nearest antenna site. When operating over the tightly limited range of the heavily populated 2.4 GHz band, as nearly all 802.11-based WiFi providers do, it is not uncommon to also see access points mounted on light posts and customer buildings.[12]

Since it is difficult for a single service provider to build an infrastructure that offers global access to its subscribers, roaming between service providers is encouraged by the Wi-Fi Alliance with the protocol WISPr, a set of recommendations approved by the alliance which facilitate inter-network and inter-operator roaming of Wi-Fi users. Modern wireless services have comparable latency to other terrestrial broadband networks.
