E******* Triples Uplink Capacity in 3G Networks

­E******* says that it has developed a unique solution that triples uplink capacity in HSPA networks.
Last month, E******* demonstrated that over-the-air uplink throughput for simultaneously active devices in a cell was increased from around 4Mbps to more than 12Mbps.The demonstrated capacity is an unprecedented figure for a 5 MHz WCDMA carrier.
This was made possible by combining E*******'s commercially available receiver technology, E******* Interference Suppression, with 4-antenna radio base stations. There is no need to upgrade cell phones or consumer devices in order to achieve this gain.
Interference Suppression is the base station receiver technology for WCDMA/HSPA that can vastly improve uplink speeds by increasing the network capacity. This is done by using advanced software algorithms in the base station that reduce the negative effects of uplink interference that is today the bottleneck in many HSPA networks.
The gains were further enhanced by the use of base stations configured with four antennas per cell.
Nils Viklund, Director WCDMA RAN at E*******, says: "We have proven that E*******'s unique Interference Suppression is a giant leap forward and it will be the new reference for WCDMA uplink performance for years to come. This can even be further enhanced by combining it with multi-receive antenna technologies. Because these technologies work with existing devices, operators that implement them will instantly benefit from the attractive gain."
