It wasn't so extended ago that we had been excited at the notion that our wireless devices operated on not just 1, but two different frequency bands.

As an Antenna Manufacturer, this meant that we required to introduce dual band mobile antennas that would allow users to attain optimal communications on both the US Cellular AMPS band at 850 MHz and the new US Digital PCS band at 1900 MHz. It was no little feat to be in a position to combine operations on every band in the dual band mobile antenna. Special care had to be taken to make sure that signals on the two bands did not interfere with every single other.

The next challenge came when cellular users wanted gear that operated in each the US and Europe. The demand for dual band mobile antennas became a demand for quad band mobile antennas. It was no longer sufficient to cover just the 850 & 1900 MHz band as would be vital for a US dual band mobile antennas, it was now desirable to cover the US bands and the European bands… in impact combining a dual band mobile antenna for the US market with a dual band mobile antenna for the European market place so that 850 & 1900 MHz had been covered for the US and 925 & 1800 MHz were covered for Europe. The unit might be utilized in only one particular country but the ability to have a single inventory produced quad band models a viable alternative.

A growing number of handheld phones as well as cellular modems for commercial use had been entering the market. Some were completely self-contained, but others had been developed to take benefit of accessories that would improve the device's overall performance. For consumer use, hands-free of charge vehicle kits were introduced. These devices consisted of a coupling device in the vehicle into which the phone was attached. The signal from the telephone then traveled by cable to an external quad band or dual band mobile antenna. The presence of the external antenna supplied a clearer signal which enhanced the user's knowledge.

On the commercial side, cellular modems had been created for more strictly information applications. These modems were used to transmit crucial information, typically from remote places. Cellular phones had been notorious for dropping calls and consequently the cellular modems were developed to minimize this risk because the data they had been transmitting was generally time sensitive and essential. These cellular modems were virtually generally attached to externally quad band or dual band mobile antennas to ensure a stronger signal.

In the final couple of years the wireless markets have come to be even a great deal more complex. With the developing demand for bandwidth and wireless capacity, further spectrum has been released for auction. In the US, auctions have been held for 3 substantial swatches of spectrum. Especially, auctions were held for the AWS 1.7 & two.1 GHz bands, the 700 MHz band, and the 2.5-two.7 GHz band.
