Today’s Wi-Fi networks are under pressure to perform, why? interference.
But not from microwave ovens, cordless phones or Bluetooth signals, it’s WiFi itself.
Traditional WiFi access points flood transmissions in all directions. Signal that goes anywhere except to the intended receiver is just interference. Complete control of your WiFi signal is the solution and if you can focus WiFi signals only where and when they’re needed, interference decreases and signal strength increases. This means larger coverage areas, faster data rates and more devices connecting at the same time. This focus in control solves one of the biggest challenges and why by today… Capacity.
WiFi uses a shared medium (frequency – if you’re wondering) just like a group of people trying to get on an escalator at the same time. Instead of a wire that carries data to each device, WiFi channels are shared among all the devices. Devices have become smaller and increased in number creating performance problems for everyone. It all comes down to physics.
Enter Ruckus Wireless BeamFlex
BeamFlex is the only adaptive WiFi antenna technology that focuses and controls WiFi signals. By increasing signal in decreasing interference WiFi performance is improved dramatically… This means more efficient connections and more room for more users giving them a better WiFi experience It also means fewer access points to buy and deploy, fewer wired drops and fewer switch ports needed… All while improving performance to each individual user.
How Ruckus BeamFlex Works
Through patented technology BeamFlex automatically creates a directional WiFi signal on the fly for every client. It does this by activating combinations of individual antenna elements each working in concert to create the best possible signal path that yields the highest data rate. However, good communication isn’t just how well a WiFi access point can talk, it’s about how well they listen.
Today’s mobile devices are smaller than ever with smaller antennas that diminish upstream performance. To make an access point listen better, the internal noise from electronic components must be controlled and reduced. If you’ve ever turned up the volume on your stereo without playing music, that’s static noise. In WiFi this system noise resulting self interference… Reducing this interference is essential. It’s also essential to be able to listen to different angles. Traditional access points were designed with vertical antennas for devices like laptops that stay in a fixed position. But today’s mobile devices are constantly used in any number of different orientations, creating a signal mismatch between the access points and clients. BeamFlex solves this with antennas that transmit and receive in both horizontal and vertical orientations to improve the reception up traffic from weaker mobile devices.
Benefits To The WiFi User & The IT Manager
One of the greatest benefits of BeamFlex is that it’s inherently compatible with all WiFi technologies whereas transmit beamforming only provides mild gains in very specific situations. It’s only supported by a limited subset of clients and it does very little to reduce WiFi noise. In addition, the ability to use to advanced techniques such as spatial multiplexing and multi-user MIMO are in direct conflict with the use of transmit beamforming.
Having complete control over communication between the access point and devices has additional technical benefits to achieve the highest possible throughput, WiFi standards make use of complex techniques like spatial multiplexing and multi-user MIMO. Maximizing these capabilities requires complete control of the signal instead of just blasting WiFi energy in all directions and hoping for the best. BeamFlex and other Ruckus Wireless optimisation technologies deliver, above all else, fast reliable WiFi service with fewer access points, less networking equipment and lower ongoing costs.
