VectaStar Gigabit
How does VectaStar work?
VectaStar uses microwave wireless point-to-multipoint network technology (often abbreviated as P2MP, PTMP or PMP) to provide an effective way to share backhaul resource between several eNodeBs (cell sites), each generating voice and packet traffic.
Wireless point-to-multipoint networks create a radio link between a central location and multiple end points.
The multipoint topology means many VectaStar Terminals can connect to one VectaStar Hub, bringing a wealth of advantages to network operators.
VectaStar delivers up to and over 300Mbps full duplex per sector, making it the next generation mobile backhaul and wireless access solution capable of exceeding today's data demands.
Point-to-multipoint - efficiency through sector traffic aggregation
Mobile backhaul network connections must have bandwidth at least equivalent to the peak data demand of the relevant cell site to ensure quality of service; however peak demand for data traffic is inherently inconsistent.
Our wireless point-to-multipoint backhaul technologies take advantage of this inconsistency.
Through statistical multiplexing, VectaStar aggregates traffic from multiple cell sites which frees up headroom for future growth.
Figure 1 demonstrates that in a point-to-multipoint topology, the ‘troughs’ of one cell site are filled by the ‘peaks’ of others, resulting in the total bandwidth requirement being significantly reduced.
A recent CBNL study proved a point-to-point microwave system would require 20.3MHz of spectrum to carry the peak traffic load whereas the VectaStar system was using only 12.1MHz, realising a 40% reduction in spectrum bandwidth.
What is more, the benefit increases as the number of sites multiplexed together goes up, giving more opportunities for a peak from one site to cancel a trough from another.
So unlike any other form of microwave backhaul, point-to-multipoint becomes more efficient as networks get denser.
