IntelliCell?

The iBurst system is based on IntelliCell technology from ArrayComm in the US to attain the extreme levels of efficiency in usage of the available radio frequency.

Through the use of advanced algorithms, IntelliCell's fully adaptive smart antenna technology dynamically adjusts signal patterns to and from each subscriber, creating a "personal cell" for efficient delivery of voice or data services. These personal cells follow people as they move, reducing radio interference.

With IntelliCell, each base station uses a small array of off-the shelf antennas coupled with ArrayComm's sophisticated signal processing techniques to dynamically control radio signals between the base station and the user terminal. The signal processing selectively amplifies each user's intended signal and rejects all unwanted signals, allowing greater numbers of users to share the spectrum. The result is a significant increase in capacity and coverage that leads to substantial reductions in the costs for infrastructure deployment, network operations, system maintenance and radio spectrum.

Conventional base stations, unlike IntelliCell equipped-base stations, transmit energy in all directions. In this instance, only a small fraction of the signal reaches the intended subscriber. The rest of the RF energy is wasted and generates noise that interferes with other users in the system. More recent techniques of "pointing" a signal to the intended user are hampered by the abundance of physical obstacles like buildings and trees that make such line-of-sight transmission impossible.

iBurst?

The iBurst technology is a wide-area mobile broadband technology offering a unique combination of high speed, wide range and high base station capacity.

The iBurst technology is a pure IP, end-to-end system built on two primary components: base stations deployed by a network operator, much like today's cellular services, and wireless modems or PC cards that a customer uses with an existing Internet appliance, such as a notebook computer, to access the service.

Unlike primarily voice networks such as GSM, CDMA and 3G standards - the iBurst technology has been designed from the ground up to provide pure data and with the incorporation of IntelliCell technology it is able to provide the wireless data much more efficiently than the voice based cellular networks. As a result the iBurst network is able to provide data rates of up to 1 Mbps to each user with a maximum base station capacity of 20 Mbps.

As well as being superior in performance, the data delivery over an iBurst network is also significantly more economical than voice networks. The data charges for iBurst based data are comparable to that charged for wired access such as DSL. In comparison, data transferred over voice networks can be up to two orders of magnitude more expensive.
