While the demand from the wireless broadband user for “high data transfer rate” at low cost is obvious, the spectrum (frequency) is limited resource. In order to meet such user demand while not compromising user experience, achieving high system spectral efficiency has become necessary objective in the design of iBurst air interface. To achieve this goal, iBurst air interface layers and protocols have been optimized while adopting the following key technological elements:
1) TDMA/TDD system,
The iBurst system is designed to provide portable broadband wireless Internet access to all subscribers including business customers anytime, anywhere. This system promises an always on, IP-centric, high-speed wireless access that provides
approximately 1 Mbps (downlink) packet data service per user while sustaining the system’s spectral efficiency, coverage and capacity. The system is uniquely designed around multiple antenna spatial processing to deliver broadband
In the mid nineties I lived in Pretoria, in Hill Street, close to Loftus. I worked for Madge Networks as a Technical Account Manager and was fighting a rearguard action with Token-ring against Ethernet.
The Madge offices in South Africa were located in Rivonia. My trip would start early mornings before 7 as with heavy traffic the journey might take up to an hour. (the situation is
