That’s the gist of an interesting blog by David Callisch of Rucks Wireless and he makes some very valid points.
When I get home this evening, I will walk into my home and immediately my two smartphones will login to my home WiFi network. I may turn on the radio which connects to online stations (via the WiFi). I may possibly even switch on the Wii console and challenge a friend to some online gaming – connected via WiFi to the internet of course.
Later I am likely to boot up my laptop and logon to the internet via WiFi, all the while my desktop PC has been connected downloading via iTunes and keeping RSS feeds up to date, using a WiFi connection – ethernet is so last decade. In addition, other members of the household are likely to piggyback the same connection with their smartphones and laptops.
My house is fairly cyber-savvy but far from unique – I haven’t yet got an internet connected fridge or TV. Yet the same broadband connection and WiFi router that ‘connected’ my home a few years back, now has double the number of connections eating its resources and it is only set to get worse.
Now David’s blog is a little bit more techie than I had first hoped – talk of gain, direction and polarity was not what I was expecting but it is an interesting read and certainly got me thinking about whether my internet connection could be so much faster with either less connections or better kit dealing with the signal.
However, beyond this there was one nugget of gold that made me sit up and really take notice: Wireless signals come in vertical and horizontal formats and the two don’t mix! I will leave you to read the blog, as David is the expert here, but the issue appears to be that in the modern world of mobile wireless devices, what we once thought was fantastic is now pretty shoddy at coping with demands of usage.
The issue arising is that position and alignment can have a tremendous effect on the quality of signal your mobile device picks up, indeed with a smartphone being moved around is very likely to see signal fade in and out even drop completely. Yet as David explains, the problem could be easily solved if the WiFi industry acknowledged what it has been pumping for years is now unsuitable.
Apparently, almost every WiFi access point sold today is pre-set to utilize vertical WiFi signals using omni-directional antennas. That is the norm, yet technology exists in the form of adaptive antennas that are designed with both horizontal and vertical antennas dealing with much of the problem.
As David points out, the industry has been heavily interested in recent years about ‘boosting’ signals when in fact more should be done in educating users about improving the signal from the base where they are actually transmitted and received.
