A Wireless ISP (WISP) provides internet access to customers using wireless technology, typically leveraging radio frequencies. Unlike traditional broadband providers that use cables (like fiber-optic, DSL, or coaxial), WISPs transmit internet data wirelessly over the air.

Here’s an overview of Wireless ISPs (WISPs):

How They Work:

  • Base Stations: WISPs set up base stations, often on towers or tall structures, which are connected to the internet. These stations transmit wireless signals over a specific area.
  • Customer Premises Equipment (CPE): Customers install equipment, often an antenna or a small dish, at their location to receive the wireless signal and connect to the internet.


  • Flexibility: WISPs can serve areas where it’s challenging or expensive to lay traditional cabling, like rural areas, hilly terrains, or islands.
  • Quick Deployment: Without the need for extensive cabling, WISPs can often deploy services more quickly than wired providers.
  • Competitive Speeds: Modern WISPs can offer speeds competitive with some wired broadband solutions, especially in areas where only slower wired technologies are available.


  • Line of Sight: Many WISP technologies require a direct line of sight between the customer’s antenna and the base station. Obstructions like buildings or trees can hinder connectivity.
  • Interference: Wireless signals can be affected by interference from other devices, weather conditions, or other radio frequency users.
  • Speed Variability: While many WISPs offer decent speeds, they might not match the top-tier speeds of fiber-optic broadband. Also, speeds can vary based on the number of users, interference, or distance from the base station.


  • WISPs might use various wireless technologies, including Wi-Fi, fixed wireless, LTE, or even licensed or unlicensed radio frequencies.
  • Emerging technologies, like 5G, could further enhance the capabilities and reach of WISPs.

Prominent WISPs:

  • The landscape of WISPs varies greatly by region. In the U.S., there are many local and regional WISPs serving specific areas, especially rural or underserved regions.
  • Larger telecom companies may also have WISP branches or services, especially for areas where their wired infrastructure doesn’t reach.


  • With the global push for better connectivity everywhere and advancements in wireless technology, WISPs have the potential to play a pivotal role in bridging the digital divide.
  • As technologies like 5G become more widespread, the distinction between traditional mobile carriers and WISPs might blur, with both offering competitive wireless broadband solutions.

In summary, Wireless ISPs provide a crucial service, especially in regions where traditional wired solutions are impractical or too expensive. With technological advancements, WISPs are poised to expand their reach and enhance their service offerings.
