Deploying a Wi-Fi network? Most of us have a Wi-Fi network deployed in our homes and many otherwise savvy business people believe that deploying one in the workplace is just as simple. If your business is going to depend on a wireless network don’t be one of the many who overlook what is necessary for a successful business network.
The IT world is rife with “pretenders”. They talk the talk but don’t walk the walk. In many data applications these individuals can get by, but depending upon the complexity of the deployment and requirements of the application, deploying a large Wi-Fi network is an area where these individuals will certainly fail.
So what do you need to do to guarantee success? First, always get references. Next, clearly define where you want coverage within your building or on your property. Third, the vendor you choose should supply a “Heat Map”. A “Heat Map” will show you in advance where you are going to have coverage and how good that coverage is going to be in any particular spot. Finally, the vendor you choose should guarantee, in writing, the heat map and that they will fix any coverage problems at their own expense, not yours.
Deploying a Wi-Fi network is going to cost more than many initially expect, but if you do your homework and you follow my advice you will be getting what you paid for. If you would like to see what a proper “Heat Map” looks like please send me an email and I will forward one along.
Last months Telcom Ambassador newsletter discussed True High Speed Internet Access. Different suppliers appear to have different definitions of High Speed. I’m not using the high speed suppliers name in this article because of the litigious world we live in. I have access to a high speed (20Mbps) internet in our office. I frequently check the speed of the connection using one of the most popular test sites www.speedtest.net and always get 20Mbps+ of internet speed. I then go to a much less popular site called www.speedtest.jbi.in to test my speed and it typically shows between 3 and 6 Mbps. Same connection same computer, tests are conducted within a 1 minute time frame and the disparity always exists! I reproduced this same test on my home internet access (3Mbps) which happens to be with a different supplier using a fiber optic network. Not so surprisingly the two sites show nearly the same results consistently – 2.4Mbps vs. 2.8Mbps. Why do I think the disparity exists? Supplier A is optimizing bandwidth to the most frequently used internet speed test sites and not optimizing it to the obscure sites. They are doing this to improve the customer’s satisfaction with the connection. I’ve felt many times that something must be wrong with my computer, when in my opinion it is the ISP giving me a very slow connection to all sites except the most popular internet speed test sites.
If Uptime, Jitter, Packet Loss and Latency (VoIP!) are important to your Business applications don’t discount using multiple T1’s. To my knowledge every CLEC that I’ve ran into over the years has always given the bandwidth that the customer has been sold. – Caveat Emptor!
