Here's a technical breakdown of Fixed Wireless Access:

  1. Wireless Transmission:
    • Frequency Bands: Fixed Wireless Access systems operate in various frequency bands, including licensed and unlicensed spectrum. Licensed bands offer more reliable and interference-free communication but require regulatory approval.
    • Antennas: Directional antennas are often used to establish a point-to-point or point-to-multipoint connection. These antennas focus the signal in a specific direction, improving the efficiency and reliability of the communication.
  2. Access Points:
    • Base Stations: FWA networks typically have fixed base stations that are strategically located to cover a specific geographic area. These base stations connect to the core network and facilitate communication with customer premises equipment (CPE) on the user end.
    • Backhaul Connection: The backhaul connection links the FWA base stations to the internet or a core network. It is a critical component that ensures high-speed data transfer between the FWA network and the broader internet infrastructure.
  3. Customer Premises Equipment (CPE):
    • Antennas and Modems: Subscribers have a CPE installed at their premises, which includes an outdoor antenna to receive the wireless signal and a modem to convert the signal into usable data for devices within the home or business.
    • Installation: Proper installation of the outdoor antenna is crucial to achieving optimal signal strength and reliability. Line-of-sight considerations are essential for effective FWA deployment.
  4. Network Architecture:
    • Last-Mile Connectivity: FWA serves as a last-mile solution, providing the final connection from the service provider's infrastructure to the end-user's location.
    • Scalability: FWA networks can be designed to scale easily by adding additional base stations or upgrading existing equipment to support more users and higher data rates.
  5. Advantages and Challenges:
    • Advantages: FWA is often chosen for its relatively quick deployment, especially in areas where laying cables is impractical or expensive. It can offer high-speed internet access in both urban and rural environments.
    • Challenges: FWA performance can be affected by environmental factors such as weather conditions, and the available spectrum may limit the achievable data rates. Interference from other wireless devices is also a consideration.
