A Wireless Internet Service Provider (WISP) is a telecommunications company that provides Internet access to customers using wireless communication technologies. Unlike traditional wired Internet Service Providers (ISPs) that rely on cable or DSL connections, WISPs use radio frequency (RF) or microwave frequencies to transmit and receive data wirelessly. Here's a technical breakdown of the key aspects of a Wireless ISP:

1. Wireless Transmission Technologies:

  • Point-to-Point (PtP) Links: Establishing direct wireless links between two fixed points using directional antennas. This is often used for backhaul connections between towers.
  • Point-to-Multipoint (PtMP) Networks: Broadcasting signals from a central hub (base station or access point) to multiple customer premises using omnidirectional or sector antennas.

2. Frequency Bands:

  • Licensed and Unlicensed Bands: WISPs may operate in licensed frequency bands acquired through regulatory authorities or unlicensed bands, such as those available in the 2.4 GHz and 5 GHz ranges.
  • Microwave and Millimeter-Wave Bands: Some WISPs use higher frequency bands for increased data rates and capacity.

3. Wireless Networking Standards:

  • Wi-Fi Standards (IEEE 802.11): WISPs often use Wi-Fi technology for customer premises equipment (CPE) to provide the last-mile connectivity. Common standards include 802.11n, 802.11ac, and the latest 802.11ax (Wi-Fi 6).
  • Wireless Broadband (WiBB) Standards: Proprietary or industry-specific standards designed for wireless broadband applications.

4. Last-Mile Connectivity:

  • Customer Premises Equipment (CPE): WISPs deploy CPE devices at customer locations, typically in the form of outdoor units with antennas. These devices establish a wireless connection with the WISP's base station.
  • Antenna Configurations: WISPs use various antenna types, such as directional antennas for longer-range connections or sector antennas for serving multiple customers within a specific area.

5. Base Stations and Access Points:

  • Base Stations: Central points in the WISP network that connect to the broader Internet infrastructure. Base stations often use high-capacity backhaul links to provide connectivity to the Internet.
  • Access Points: Devices that serve as hubs for connecting multiple CPEs in a PtMP configuration.

6. Backhaul Connections:

  • High-Capacity Links: WISPs establish high-capacity links between towers or base stations to connect their network to the broader Internet backbone.
  • Microwave Links: In some cases, point-to-point microwave links are used for backhaul connections.

7. Network Topology:

  • Mesh Networks: Some WISPs deploy mesh network topologies where nodes in the network are interconnected, allowing for redundancy and self-healing capabilities.
  • Tree Topologies: In PtMP configurations, a tree-like topology may be used with a central access point serving multiple CPEs.

8. Wireless Security Measures:

  • Encryption Protocols: WISPs implement encryption protocols, such as WPA2 or WPA3, to secure the wireless communication between CPEs and the base station.
  • Authentication Mechanisms: Ensuring that only authorized CPEs can connect to the WISP network.

9. Quality of Service (QoS) Implementation:

  • Traffic Prioritization: Prioritizing certain types of traffic to ensure a consistent quality of service for applications like video streaming or VoIP.

10. Spectrum Management:

  • Channel Planning: Optimizing the allocation of frequency channels to minimize interference and maximize network performance.
  • Frequency Reuse: Efficiently using the available spectrum by reusing frequencies in different geographic areas.

11. Regulatory Compliance:

  • Spectrum Licensing: Obtaining licenses from regulatory authorities for the use of specific frequency bands.
  • Compliance with Standards: Adhering to industry standards and regulations for wireless communication.

12. Capacity Planning and Network Optimization:

  • Load Balancing: Distributing traffic across multiple access points to optimize network performance.
  • Spectrum Analysis: Monitoring the wireless spectrum to identify and mitigate interference.

13. Scalability:

  • Adding Capacity: WISPs can scale their networks by adding more base stations, access points, or upgrading backhaul connections to accommodate increasing user demand.

14. Weather and Environmental Considerations:

  • Fading and Signal Propagation: Understanding the impact of weather conditions on signal propagation, including rain fade or atmospheric absorption.
  • Antenna Alignment: Ensuring precise alignment of antennas, especially in PtP links, to maintain signal integrity.

15. Emerging Technologies:

  • 5G Integration: Some WISPs explore integrating 5G technologies to enhance network performance and support new use cases.

Summary:

Wireless ISPs play a crucial role in providing broadband Internet access to areas where traditional wired infrastructure may be challenging or economically unfeasible. By leveraging wireless transmission technologies and strategically deploying base stations and CPEs, WISPs can create reliable and scalable networks to deliver Internet connectivity to homes, businesses, and remote locations.
