iBurst uses multi-carrier wideband technology that divides
the 5 MHz band into 8 channels.
This system assigns each channel asymmetrically. The data rate
uplink being 1/3 and downlink being 2/3.
Therefore, 340 Kbps x 3 slots is a maximum downlink data rate
which is 1061 Kbps.
Furthermore, iBurst adopts 24QAM, for the first time. 24QAM
increases the amount of data per symbol, a “symbol”
being the amount of data that is provided to each terminal.
This is one of the reasons why a maximum data rate of 1 Mbps
is possible even though the system is wireless. |

This is how iBurst delivers a maximum data rate of 1 Mbps, but what it really features is that, unlike conventional systems where data rate slows when many users are online, iBurst ensures a high data rate even while many users are simultaneously connected.
The reason behind this is the use of SDMA.
By this technology iBurst can duplicate one frequency to max three and allows multiple users at the same time.
Moreover, Adaptive Array Antenna technology takes full advantage of radio waves in two unique ways:
1. It enables the base station to concentrate terminal radio signal, and 2. It features interference reduction, preventing emissions to other terminals which interfere their communication. Using this technology, transmission power is focused on the subscriber unit in real time, while mutual interference from neighboring base stations are suppressed.
These technologies that effectively use radio waves -- iBurst makes it possible to build an environment that many users can use and which ensures a 1 Mbps data rate even when many users are simultaneously connected |
