PCTEL Board of Directors Authorizes Stock Buyback
, A leader in antenna and scanning receiver solutions, announced today that the Board of Directors authorized an additional $5 million to buyback shares of the company's stock. The company will continue to buyback shares during the company's regularly scheduled open trading window, which is typically the middle five weeks of each quarter. In addition, the company will establish a 10b-5 program that will permit buyback of shares at times other than when the scheduled window is open."We believe that PCTEL has a strong future and that we have an unusual opportunity to invest directly in our company," said Marty Singer, PCTEL Chairman and CEO. "Ultimately, however, our goal is to invest in the growth of our business and to expand through acquisition and organic investment. Over the past 18 months, we have acquired four assets and we intend to evaluate other opportunities," added Singer.

I first tried using a WiFi Booster. To impress on the promise of a effective solution I acquired the most powerful 1Watt booster I could find on Ebay. Knowing that the default transmission output on most WiFi devices being in around the 0.025 Watt range, I was absolutely sure that I should be able to notice a definite increase in my range. I even tried ordering several Chinese knock-off 9dbi and 12dbi antenna's as well. I performed empirical tests with a Pocket PC and two computers in fixed positions away from each other over a extended period of time to achieve accurate results. All the other non-brand name antenna's worked with a signal level comparable to or worse than the stock 2dbi antenna. It would have seemed that the knock off's were either not manufactured properly or were mismatched to the used frequencies. Aside from the signal quality, the Chinese Knock-off's either were advertised at different gains for the same antenna's and quite often you are unable to use the antenna without the corded stand as they use a proprietary gendered connection type which is not usable with real life WiFi units. Disappointed in them I threw them out rather than trouble myself with spending time repackaging and paying to ship them back to China. So I decided to use the D-link antenna as my first choice before proceeding further as it was the "Only choice". I tested the 1Watt boosters for 6 months straight. After 6 months I had all the boosters degrade to a failed mode where they actually worsened the WiFi signals. In the beginning however they did boost the range of the WiFi but only noticeable on the transmission aspect of things. The boosters work by switching between transmit mode and receive mode in a "Half-duplex" manner. It must be able to detect when the WiFi device is trying to transmit and switch into the transmit mode to do so. This usually takes time to go into the transmit mode, which they refer to as "Time Division". That means that it can only transmit or receive...
