Fixed Wireless Access (FWA):

Fixed Wireless Access (FWA) is a method for providing wireless connectivity between two fixed points, such as buildings or houses. Instead of using physical cables (like fiber-optic cables or copper wires), FWA relies on radio signals to transmit data between the point of origin and the endpoint.

Technical Aspects of FWA:

  1. Radio Frequency (RF) Spectrum: FWA systems operate within specific radio frequency bands. These bands can be licensed (where operators need permission to use them) or unlicensed (available for public use).
  2. Transceivers: At both ends of the FWA link, there are transceivers. These devices have the capability to both transmit and receive signals. They modulate data into radio waves for transmission and demodulate incoming signals back into data.
  3. Antennas: Antennas play a crucial role in FWA. They capture radio signals from the air and transmit them to the destination. The design and type of antenna can influence the range, capacity, and reliability of the FWA system.
  4. Line-of-Sight (LOS): For FWA to be effective, there's typically a need for a clear line of sight between the transmitting and receiving antennas. Obstructions like buildings, trees, or terrain can degrade or entirely block the signal.

Fiber Optic Technology:

Fiber-optic technology uses light signals to transmit data over thin strands of glass or plastic fibers. Here's a breakdown of its technical aspects:

  1. Core and Cladding: A fiber-optic cable consists of a core (where light travels) and a cladding (a layer that reflects the light back into the core, ensuring it stays within the fiber). The core is made of high-quality silica glass or plastic.
  2. Light Sources: Typically, lasers or light-emitting diodes (LEDs) are used as light sources in fiber-optic systems. They produce light signals that are injected into the fiber for transmission.
  3. Data Transmission: When data is transmitted, it's converted into light pulses. These pulses travel down the fiber without significant loss over long distances. At the receiving end, the light pulses are converted back into electrical signals and then into usable data.
  4. Bandwidth and Speed: One of the significant advantages of fiber-optic technology is its high bandwidth capacity. It can handle vast amounts of data at incredible speeds, making it ideal for applications like high-speed internet, video streaming, and telecommunication.

FWA and Fiber:

In some scenarios, FWA can be used as a last-mile solution to provide connectivity to areas where laying fiber-optic cables might be challenging or expensive. For instance:

  1. Cost-Effective Solutions: Instead of deploying fiber-optic infrastructure to every household or business, operators might use FWA to provide the last-mile connection. This approach can reduce the overall deployment costs.
  2. Complementary Technologies: FWA and fiber can work together to create hybrid networks. Fiber can serve as the backbone or main infrastructure, while FWA can provide connectivity to specific areas or locations.
  3. Speed and Capacity: While fiber offers higher speeds and bandwidth compared to FWA, in scenarios where laying fiber is impractical or not feasible, FWA can offer a viable alternative.
