WHY WirelessNET Africa?


Wireless as a technology has matured from a cutting edge “only-to-be-used-in-an-emergency” technology into a mainstream, and in many cases, primary means of providing connectivity. Within any given metropolitan, suburban or rural area, broadband wireless access is by far the easiest and most cost-effective way to implement your high performance network. Whether you’re creating a network from scratch, or need to augment or replace your existing wire line links, broadband wireless access is the most reliable and cost-effective, high-speed data networking alternative you should know more about.

Before you test just how fast your network connection is, remember that you are limited by the package by which you have purchased. Even if the equipment is capable of carrying higher speeds, you may be limited by your package.

You can get a very good estimate of your throughput capacity by flooding the link with traffic and measuring how long it takes to transfer the data.

While there are web pages available that will perform a “speed test” in your browser (such as http://www.dslreports.com/stest or http://speedtest.net/), these tests are increasingly inaccurate as you get further from the testing source. Even worse, they do not allow you to test the speed of a given link, but only the speed of your link to a particular site on the Internet. Here are a few tools that will allow you to perform throughput testing on your own networks.

http://fgouget.free.fr/bing/index-en.shtml. Rather than flood a connection with data and see how long the transfer takes to complete, Bing attempts to estimate the available throughput of a point-to-point connection by analyzing round trip times for various sized ICMP packets. While it is not always as accurate as a flood test, it can provide a good estimate without transmitting a large number of bytes.

A clear line of sight (LoS) is one of the most important conditions for creating reliable wireless links. All wireless signals are attenuated when they encounter obstructions. The goal for every network designer is to reduce the amount of attenuation by deploying clear LoS links.

Despite what the term LoS implies-the ability to see from point A to point B without any obstructions, wireless line-of-sight requires more than being able to easily see from one location to another. Wireless signals travel in waves, not straight lines, which mean that the signal is radiated outwards from the antenna-not linearly.

Yes, there is one Bandwidth Optimisation facility which has been well accepted amongst providers called ViBE.

Information on how ViBE works and other Bandwidth optimisation methods can be found in our Forum under Bandwidth Optimisation.

Microwave systems can be designed to provide "5 nines" availability.

Obviously, anything that blocks the transmission path for a substantial length of time will affect performance. Properly designed systems are virtually unaffected by rain, snow or fog. Design engineering includes an availability statistic which states a given percentage uptime. Design goals are so-called "5 nines" or 99.999% availability which translates into a few minutes annually.

Other than the effects of atmospheric conditions, the only other variable is the equipment itself, which is no different than any other electronic device.

Absolutely. The degree of latency is very low since microwaves travel near light speed. Consider a microwave path as just another piece of plumbing, except that instead of water, you're delivering bits of information.

It depends on what you're sending, whether IP or T Carrier, and the system that you use. When it comes to IP, if the information is encrypted before it is transmitted, then depending on the type of transmission, it can be very secure.

In some cases, manufactures equipment can sense when a potential hacker attempt is made, and will shut both ends down. In other cases, specific matches between transmitting and receiving are part of a design, so unless there is an exact match, hacking of data becomes impossible.

ICASA regulates all radio transmission, whether licensed or non-licensed. With that said there are frequencies set aside by ICASA for non-licensed situations.

Basically, you can install a system without the time and expense involved in getting a license. The problem with non- licensed technology is that ANYONE can put up a system that might interfere with another system. There's no such thing as "squatter's rights". If you have interference, and you can't arbitrate or eliminate the problem, then you're stuck.

Like any wireless signal, changes to the environment can cause interference, however only severe rain and snow should affect your service.

There are known issues with interference, including (but not limited to) amateur radios, existing microwave towers or antennas, and other 2.4 or 5.8 Ghz wireless devices. If you have a 2.4 Ghz cordless phone, you will need to locate it at least 10 feet away from your computer, antenna cable, and/or antenna.
