You have limited bandwidth and limited tower space, yet your needs to deliver massive amounts of data aren’t going away. Working with what some businesses have is equivalent to reading War and Peace (Leo Tolstoy’s book with 361 chapters) by covering a chapter a day, for a year. This may be fine for someone casually reading a novel, but when it comes to business-critical data, you need a better solution.
Point-to-multipoint radio systems
The obvious answer is use WIFI. We have thousands of people on point-to-multipoint WIFI systems. And while that may sound exactly like a cellular solution, the limiting factor is distance.
Your WIFI network is 10 m to 100 m, while cellular can cover up to 20 Km, and fails to cover a lot of rural areas. Point-to-multipoint radios can be 60 km.
Knowing this, why would anyone restrict themselves in terms of bandwidth and frequencies. Isn’t bandwidth unlimited in this day and age? What is bandwidth anyways? Why Point to Multipoint
Bandwidth – The volume of data per unit of time that can be moved. This directly correlates to the amount of frequency or spectrum that is used.
Still trying to figure out bandwidth? Let’s talk latency first and then put them together.
Latency – The time interval between stimulus and response. If you are streaming video, latency can be a little annoying, but if you are trying to have a conversation and there is a huge delay waiting for the person to answer you then that is a big problem.
Let’s look at the concept of bandwidth and latency using our initial War and Peace analogy.
If I have a copy of War and Peace and I send all 361 chapters at once to someone in Spain through the mail, and await their response using the same mail system, it may take three to six weeks to complete the back and forth.
The bandwidth is the amount of data I could send at one time and the latency is the delay in the network for my data to transport. If I send each chapter one at a time and get a thank you every time and we assume the entire transaction takes three weeks every time. Then that is 1083 weeks of back and forth.
Receiver Sensitivity and Cheating God
If someone is talking to you and you stay still and they start walking away, eventually you will not be able to make out the words and then you will not be able to hear any sound they make…but there is a point there where you don’t hear all the words but you can guess correctly and still figure out what they are saying.
Instead of sound waves. Xetawaves does this with electromagnetic waves and with error correction. Receiver sensitivity is the lowest power level at which the receiver can make sense of the signal. This is how we get receiver sensitivity of up to –116 dB. Physics says it cant be done but Xetawave does it anyways. Cheating God.
Xetawave just does it better. For point to multipoint radio systems Xetawave has faster speeds over longer distances across all supported frequencies…and your old Xetawave models will always talk to your new Xetawave models.
Xetawave Radios – There can should be only One…Protocol
This radio is meant to last the lifecycle of the asset and it will always be backward compatible to other Xetawave model numbers…we don’t force you to change
