FWA (fixed wireless access)

Last updated on 

Fixed Wireless Access (FWA) is a method of providing internet connectivity to users using radio waves rather than a traditional wired connection. FWA technology can be deployed in both rural and urban areas and can offer a fast and reliable internet connection to homes, businesses, and other locations that may not have access to traditional broadband services.

In this article, we will provide an overview of FWA technology, including how it works, its benefits and limitations, and some examples of FWA deployments.

How does FWA work?

FWA technology uses radio waves to transmit data between a user's location and a nearby base station. The base station is typically connected to a wired network such as a fiber-optic or copper cable, which provides access to the internet.

When a user requests data, such as a web page or a video stream, the request is sent wirelessly from the user's location to the nearest base station. The base station then retrieves the data from the internet and sends it wirelessly back to the user. This process is known as the "last mile" connection, as it is the final leg of the data transfer from the internet to the user's location.

FWA technology uses various frequencies of radio waves to transmit data. Lower frequency waves can travel longer distances and penetrate buildings and other obstacles more easily, but they have lower data transfer rates. Higher frequency waves have higher data transfer rates but cannot travel as far and are more easily blocked by obstacles.

To provide FWA service, a network operator must deploy a network of base stations that are strategically located to cover the desired service area. Each base station can typically serve multiple users within a certain radius, depending on the frequency of the radio waves being used and the terrain and other obstacles in the area.

Benefits of FWA

FWA technology offers several benefits over traditional wired broadband connections. Some of the key advantages of FWA include:

  1. Accessibility: FWA can provide high-speed internet access to users in areas where traditional wired broadband services are not available. This is particularly important in rural and remote areas where laying fiber-optic or copper cable can be expensive or impractical.
  2. Affordability: FWA technology can be more cost-effective than traditional wired broadband services, both in terms of initial installation costs and ongoing maintenance and upgrades.
  3. Flexibility: FWA technology can be deployed quickly and easily, making it an attractive option for temporary or mobile deployments such as at events or in disaster relief scenarios.
  4. Reliability: FWA technology can be more resilient than traditional wired broadband services in areas prone to natural disasters or other disruptions, as it does not rely on physical cables that can be damaged or destroyed.
  5. High-speed: FWA can provide high-speed internet access, with some deployments offering speeds of up to 1 Gbps.

Limitations of FWA

Despite its many benefits, FWA technology also has some limitations. Some of the key limitations of FWA include:

  1. Line of sight: FWA technology relies on a clear line of sight between the user's location and the base station. Obstacles such as buildings, trees, and hills can block or weaken the signal, limiting the coverage area and reducing the data transfer rate.
  2. Interference: FWA technology can be subject to interference from other wireless devices and networks operating in the same frequency range.
  3. Capacity: FWA technology may have limited capacity, particularly in densely populated areas where many users are accessing the network simultaneously.
  4. Security: FWA technology may be more vulnerable to security threats such as hacking and eavesdropping than traditional wired broadband services.
  5. Upgrades: FWA technology may require frequent upgrades to keep pace with advances in wireless technology and changing user demands.

Examples of FWA Deployments

FWA technology is used in a variety of deployments around the world, from rural areas with limited broadband infrastructure to urban areas with high demand for fast internet access. Here are a few examples of FWA deployments:

  1. Microsoft Airband Initiative: Microsoft's Airband Initiative is a program that aims to bring broadband access to underserved areas in the United States using FWA technology. Microsoft has partnered with local internet service providers (ISPs) to deploy a network of base stations that provide high-speed internet access to users in rural areas.
  2. Google Station: Google Station is a program that provides free Wi-Fi access to users in public spaces such as train stations, airports, and cafes in countries such as India, Indonesia, and Mexico. Google uses FWA technology to provide the last mile connection from the base station to the user's device.
  3. Starry: Starry is a US-based ISP that uses FWA technology to provide high-speed internet access to users in select cities. Starry's base stations use millimeter-wave technology to deliver speeds of up to 1 Gbps to users within a certain radius.
  4. Rain: Rain is an ISP in South Africa that uses FWA technology to provide high-speed internet access to users in urban and suburban areas. Rain's base stations use a combination of frequency bands to provide coverage and capacity, with plans offering speeds of up to 5 Gbps.
  5. Rakuten Mobile: Rakuten Mobile is a Japanese mobile network operator that uses FWA technology to provide broadband services to users in rural areas. Rakuten's base stations use a combination of low and high frequency bands to provide coverage and capacity, with plans offering speeds of up to 1 Gbps.

Conclusion

FWA technology offers a flexible, cost-effective, and reliable way to provide high-speed internet access to users in both rural and urban areas. While it has some limitations such as line of sight, interference, and capacity, FWA technology is constantly evolving to address these challenges and keep pace with advances in wireless technology.

As more and more users demand high-speed internet access, FWA technology is likely to play an increasingly important role in meeting this demand and bridging the digital divide between those with access to broadband services and those without.
