Battle out Wireless Interference with ePMP 2000lick
“If you know the enemy and know yourself, you need not fear the result of a hundred battles. If you know yourself but not the enemy, for every victory gained you will also suffer a defeat. If you know neither the enemy nor yourself, you will succumb in every battle.”
― Sun Tzu, The Art of War
Let’s get to know the enemy – Interference
What is it?
Interference is anything which modifies or disrupts a signal as it travels along a channel between a source and a receiver or the addition of unwanted signals to a useful signal.
Why is it bad for wireless transmission?
1. Trouble connecting to wireless devices
2. Slow speeds
3. Low throughput
4. Intermittent disconnections
5. UNHAPPY CUSTOMERS!
Now, let’s get to know ourselves…
Wireless networks design and deployment primarily calls for an understanding of customer requirements and the environment you’re going to deploy your wireless APs, with the aim of giving quality service. With interference being a major constant setback, providers always result to channel shifting -manual or automatic- trying to find the next cleanest channel to transmit, up until everyone else finds it, and you’re back to square one.
Victory gained in channel shifting, but still suffering defeat from constant interference.
So, how do you beat interference?
1. Beamforming technology
In very simplified terms, beamforming is all about focusing a wireless signal in a specific direction to a subscriber, as opposed a general signal broadcast to a group of subscribers.
This blocks out noise from undesired interferers improving signal reception, resulting in improved wireless bandwidth utilization, and increased wireless network’s range.
The end result is quality of service delivery for latency-sensitive transmissions like HD video streaming and voice.
2. GPS Synchronization
Imagine an access point transmitting signals to subscribers and vice versa at random different times. This is bound to cause self interference, the worst kind, because there are signals colliding at your own AP, from subscribers and similar co-located APs. It’s like an orchestra without a conductor; all instruments playing at different uncoordinated times. That’s basically noise!
With GPS synchronization, an access point uses GPS satellites for accurate timing, to harmonize transmissions to and fro the subscribers and co-located APs as well, so that they happen at the exact same time. This mitigates self interference and you end up with a harmonized [synchronized] signal orchestra, with an accurate GPS conductor. Can you feel the music?
What if you had all this innovative technology in one system?
