fixed wireless access broadband

Fixed Wireless Access (FWA) broadband is a type of wireless communication that provides high-speed internet access to fixed locations, such as homes or businesses. It differs from mobile wireless services, which are designed for users on the move. FWA uses radio signals to establish a wireless connection between a customer's location and a base station, which is typically connected to a wired network infrastructure.

Here's a technical breakdown of how Fixed Wireless Access broadband works:

  1. Base Station (Access Point):
    • The FWA network begins with a base station or access point. This station is typically a tall tower or antenna located in a central location. It serves as the central hub for connecting multiple customer locations to the internet.
  2. Customer Premises Equipment (CPE):
    • At the customer's location, there is a device known as the Customer Premises Equipment (CPE). The CPE is usually a small outdoor antenna or radio transceiver installed on the roof or wall of the building. This device is responsible for establishing a wireless connection with the base station.
  3. Line-of-Sight (LOS) and Non-Line-of-Sight (NLOS):
    • The effectiveness of Fixed Wireless Access often depends on having a clear Line-of-Sight (LOS) between the base station and the customer's CPE. LOS means there are no physical obstacles, like buildings or hills, blocking the direct path between the two points. In some cases, FWA can also work in Non-Line-of-Sight (NLOS) scenarios, where obstacles are present, but the signal can still be reflected or refracted to establish a connection.
  4. Frequency Bands:
    • FWA systems operate in various frequency bands, including both licensed and unlicensed bands. The choice of frequency bands affects the range, data rates, and penetration capabilities of the wireless signal. Higher frequency bands typically offer higher data rates but may have shorter ranges and lower penetration through obstacles.
  5. Modulation and Coding:
    • The wireless signals are modulated and encoded to transmit data efficiently over the air. Different modulation and coding schemes are used based on factors like signal strength, interference, and available bandwidth. Advanced modulation techniques can increase the data transfer rates but may require a stronger and more reliable signal.
  6. Backhaul Connection:
    • The base station is connected to the internet through a backhaul connection. This connection is typically a high-capacity fiber optic link that provides the necessary bandwidth to support multiple simultaneous connections from various customer locations.
  7. Network Infrastructure:
    • The base station is part of a larger network infrastructure that includes routers, switches, and other networking equipment. These devices manage the flow of data between the fixed wireless network and the broader internet.
  8. Security Measures:
    • Security protocols, such as encryption, are implemented to protect the data transmitted over the wireless connection. This is crucial to ensure the privacy and integrity of customer information.

Fixed Wireless Access broadband offers an alternative to traditional wired broadband technologies, particularly in areas where deploying fiber-optic or cable infrastructure is challenging or cost-prohibitive. It provides a flexible and scalable solution for delivering high-speed internet access to homes and businesses.
