Prior to conducting our product review, we spent a lot of time researching all the various WiFi boosters that are available on the market. We looked not only at the power and range specifications, but also looked for differing sizes to fit the various types of situations that we felt RV'ers would encounter based on the feedback from our Product Testing Review.
The products that we short listed were 1) a 1.2W High Power external antenna for the roof, ladder or flag-pole mounting, 2) a mini-WiFi booster for it's extreme portability, 3) a High-Gain Antenna for it's unique design, and 4) a 1W Desktop Antenna for it's great price, excellent specifications and good portability.
From our Product Testing Review, the feedback that we got was that the Range and Speed are the primary considerations for a WiFi booster, followed by Ease of Use, Technical Support, Portability and then price. We wanted to conduct a test that was as realistic as possible and so tested each product at an RV campground. Although there was no high power WiFi available to test the range (remember that in order to get a good distance, you need not only a powerful WiFi booster, but a powerful WiFi transmitter, just like two-way radios). There was a good fast open WiFi network which we could just pick up in the back of our RV, but not in the front, and so this became our test subject.
Speed was tested with a number of different tests that attempted to simulate the type of tasks the WiFi might be used for. These were:
To try to give a feel for how the products performed, each of the results was normalized by comparing it to how my Sony Vaio laptop performed on its own, without the booster. The graph therefore show how much faster (or slower) the speed was using each product. A couple of points to note are that the upload speeds are all fairly similar. This is because they were not really fast enough to stress the WiFi connection (notice how the download speeds show a much bigger difference).
So here's the results in order (best first):
