WISP stands for Wireless Internet Service Provider. It's a technology that allows the delivery of high-speed internet access to customers using wireless communication links. WISP networks typically use radio frequencies to transmit data from a central location, often a tower or base station, to a receiver located at the customer's premises. This technology is particularly useful in areas where traditional wired internet infrastructure like cable or fiber optics is not available or economically feasible.

Here's a more detailed technical explanation of how WISP technology works:

  1. Base Station or Access Point: At the core of a WISP network is the base station or access point. This station is equipped with high-gain antennas and networking hardware. It's connected to the internet backbone, usually through a wired connection like fiber optic cables, and serves as the central hub for transmitting and receiving data.
  2. Wireless Transmission: The base station communicates with customer premises equipment (CPE) or receivers using radio frequencies. It utilizes directional antennas to create wireless links with CPE devices installed at the customer's location. These antennas are often mounted on towers, rooftops, or other elevated positions to achieve better line-of-sight communication.
  3. Frequency Bands: WISPs use various frequency bands, such as 2.4 GHz, 5 GHz, and sometimes higher frequencies in the millimeter-wave range, depending on regulatory permissions and available spectrum. Higher frequency bands often provide faster data speeds but have shorter ranges and may face more interference from environmental factors.
  4. Point-to-Point and Point-to-Multipoint Links: WISP networks can deploy two main types of wireless links:
    • Point-to-Point (PtP): These links establish a direct connection between the base station and a specific CPE. They are used for longer-distance connections between two fixed points.
    • Point-to-Multipoint (PtMP): PtMP links allow the base station to communicate with multiple CPE devices simultaneously. This is commonly used to serve multiple customers within a specific coverage area.
  5. CPE Equipment: Customers receive internet connectivity via CPE devices installed at their premises. These devices consist of an outdoor antenna or receiver that communicates with the WISP's base station. The received signal is then transmitted to a router or modem inside the customer's home or business, providing internet access to their devices via Wi-Fi or Ethernet.
  6. Network Management and Control: WISP networks are managed centrally from the base station. Network administrators monitor and control the network's performance, allocate bandwidth, manage connections, and troubleshoot issues remotely using specialized management software and tools.
  7. Obstacles and Interference: WISP performance can be affected by various factors such as weather conditions, physical obstacles (like buildings or trees blocking the signal path), and interference from other wireless devices operating in the same frequency range.
