Later this year a 512 Kbps Airlink Wireless II version will be available. An advanced bandwidth control protocol for the air interface has been integrated into the Airlink Wireless System to ensure that a guaranteed portion of the available bandwidth is provided to each customer station during times of high traffic load. The Airlink Wireless System's intelligent bandwidth control is able to automatically assign more bandwidth to a customer station with higher demand when the other customer stations have lower bandwidth demand. The Airlink Wireless System has a raw data rate on the RF link of 625 Kbps. However, the advertised bandwidth is only the amount available to the customer, or 128 Kbps.
Many wireless companies advertise very high data rates with their wireless products.
What they do not always tell you is that, in many cases, that bandwidth number is actually the raw data rate, not the bandwidth available to the end user. The Airlink Wireless System operates in the 2.4 GHz unlicensed ISM band, which has been set aside by the government for public use. Airlink Wireless's performance is not markedly affected by other systems operating in the 2.4 GHz range. Airlink Wireless's secure, robust transmissions are attributable, in part, to the system's ability to quickly change channels, which is critical for fast data throughput. If the channel in use experiences interference, the Airlink Wireless System moves to another within 8 milliseconds.
