Introduction to WISP Technology
Wireless Internet Service Providers (WISPs) represent a innovative approach to delivering internet connectivity, particularly in areas where traditional wired infrastructure is impractical or cost-prohibitive. Unlike conventional Internet Service Providers (ISPs) that rely on physical cables, WISPs leverage wireless networking technology to bridge the digital divide.
WISPs operate by transmitting internet signals through the air, using fixed wireless communication methods. This technology allows them to provide high-speed internet access to rural, underserved, or geographically challenging areas where laying fiber optic cables or copper lines would be logistically difficult or economically unfeasible.
The Core Principles of WISP Operations
At the heart of WISP operations lies a network of strategically placed wireless towers or base stations. These structures serve as the central hubs for signal transmission, broadcasting internet connectivity across a wide area. The base stations are typically mounted on tall structures such as dedicated communication towers, existing cellular towers, water towers, or even tall buildings to maximize coverage area.
WISPs employ point-to-multipoint communication, where a single base station can serve multiple end-users. This efficient model allows for broad coverage with minimal infrastructure. The system relies on line-of-sight or near-line-of-sight technology, meaning that obstructions between the base station and the customer's receiver can impact service quality.
Frequency Bands and Signal Transmission
WISPs operate on a variety of frequency bands, each with its own characteristics and regulatory considerations. These can be broadly categorized into licensed and unlicensed spectrum:
  • Licensed bands (e.g., 3.5 GHz CBRS) offer more reliable and interference-free operation but require regulatory approval and often come at a higher cost.
  • Unlicensed bands (e.g., 2.4 GHz, 5 GHz, 6 GHz) are freely available for use but may face more interference from other devices operating in the same spectrum.
The choice of frequency band impacts factors such as range, capacity, and susceptibility to interference. Higher frequency bands generally offer greater bandwidth but are more susceptible to atmospheric interference and have shorter range.
