Fixed Wireless Access (FWA) Network:
Fixed Wireless Access (FWA) is a broadband service that provides high-speed internet access using wireless communication, typically over radio frequencies. Here's a technical breakdown:
- Base Station (BS):
- In a fixed wireless network, there are base stations strategically placed to cover a specific geographic area.
- These base stations are equipped with antennas and networking equipment.
- Subscriber Unit (SU) or Customer Premises Equipment (CPE):
- Customers have a subscriber unit or CPE installed at their premises. This device communicates wirelessly with the base station.
- The CPE is usually a modem-like device that can receive and transmit signals over the wireless network.
- Frequency Bands:
- FWA networks operate in various frequency bands, including licensed and unlicensed bands. The choice of frequency bands depends on factors like regulatory approval, available spectrum, and the desired coverage.
- Modulation and Encoding:
- FWA networks use advanced modulation and encoding techniques to transmit data over the air efficiently.
- Higher-order modulation schemes and error correction coding are employed to maximize data throughput and improve reliability.
- Antenna Technology:
- Both base stations and subscriber units use directional or omnidirectional antennas, depending on the specific deployment scenario.
- Smart antenna technologies may be used to enhance signal quality and mitigate interference.
- Backhaul Connection:
- The base station needs to be connected to the internet backbone. This is often done using wired connections like fiber optics or point-to-point wireless links.
- Network Management:
- FWA networks require robust network management systems to monitor and optimize performance.
- Quality of Service (QoS) mechanisms are implemented to ensure that different types of traffic receive appropriate priority.
- Security:
- Security measures, including encryption and authentication, are crucial to protect data transmitted over the wireless links.
- Scalability and Capacity:
- FWA networks need to be scalable to accommodate growing numbers of subscribers.
- Capacity planning involves optimizing the network for increased data demands.
- Regulatory Considerations:
- Compliance with regulatory requirements is essential. This includes adherence to spectrum allocations and emission limits set by regulatory authorities.
