Wavion Technology

Wavion has developed spatially adaptive beamforming and SDMA technologies, which will become the next-generation of multiple-antenna, outdoor Wi-Fi networks. These powerful technologies offer superior performance in infrastructures working with off-the-shelf 802.11 standards-based Wi-Fi clients.

The Challenge

We are living in the midst of the information age. Along side the explosion in information, comes our desire to be able to access it at any time, in any place.  The widely available off-the-shelf 802.11 Wi-Fi portable clients are laptops, PDA etc. makes Wi-Fi networks a lucrative proposition for network operators. However, there are a number of key challenges that need to be met in order to create a truly effective outdoor and metro Wi-Fi solution

  • Metro Wi-Fi base stations currently use a single radio for the access, and simple antenna diversity. This is a technology that suffers from short range, limited capacity, and is adversely affected by multipath. The result is dense access point deployment and costly infrastructure in addition to a low service quality network plagued by spotty coverage.
  • Outdoors metro Wi-Fi environments present much tougher electromagnetic challenges than indoors environment, including much higher levels of interference, much higher multipath delay-spread, and much faster moving objects and users such as cars. Current access points are typically based on commoditized semiconductors designed for indoor environments, which are not able to effectively handle the physical dynamics of outdoor environments.

Wavion's solution

Wavion is the only company to have developed Wi-Fi outdoor optimized technology, in a cost effective package, including it’s own ASIC, beamforming and SDMA technologies.

  • Based on multiple antennas and radio receivers with custom-designed application-specific integrated circuits (ASICs) and embedded software.
  • Optimized for outdoor metro Wi-Fi networks without requiring any changes to standard Wi-Fi clients

The result is the best performance in terms of throughput, range, indoor penetration and interference mitigation, which ensures that providers are able to offer cost effective, top quality service. Providers can save on capital and operating expenses, accelerating return on investment and making metro and rural wireless services affordable for a broad range of municipalities and enterprises.

Wavion technology advantages

Coverage
The coverage area provided Wavion’s technology is two to three times that of conventional Wi-Fi Access Points. Superior range and uniform coverage means that the network can be scaled to reach a larger group of users, which can yield higher subscriber revenues at lower costs.

Wavion’s technology provides users with a powerful, high quality signal that is not dependent on line-of-sight positioning, and is highly resistant to interference. This results in a much improved uniform coverage with far fewer dead spots and allows mobile users to get stronger connections with fewer re-associations between access points while the cli­ent is in motion.

Capacity
The spatially adaptive technology improves the link budget, which significantly increases the throughput to Wi-Fi clients. The technology also minimizes the “fading phenomena” where Wi-Fi clients experience rate drops from time to time. This provides further improvement on the effective capacity of the infrastructure.
This capacity increase, allows the operator to offer higher grade of service to clients, as well as increasing the number of clients that can be served per base station.

Indoor Penetration
Indoor penetration is very susceptible to multipath and signal reflection. Since the spatially adaptive technology exploits multipath to increase bi-directional link budget, it is has a superior ability to penetrate buildings and walls compared to any conventional access points. This enables network operators to offer access in residences, places business and schools. In addition, deeper indoor penetration makes self-install service a reality by reducing the need for separate outdoor CPEs.

Interference immunity
Wavion’s technology has incorporated advanced mechanisms for interference handling. It’s Dynamic Interference Handling (DIH) as well as its beamforming technology which concentrates the antenna beam only on the client, allows operation in severe interference conditions. This minimizes the effect that interference may have on the performance in terms of capacity and coverage.
