Ericsson has developed a solution that triples uplink capacity in HSPA networks. This allows operators with a large number of end users to offer high uplink data speeds.
On January 25, 2012, Ericsson demonstrated that over-the-air uplink throughput for simultaneously active devices in a cell were 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 Ericsson's commercially available receiver technology, Ericsson 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.
Nils Viklund, Director WCDMA RAN, Ericsson, said, "We have proven that Ericsson'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."
Ericsson has also successfully demonstrated that it is possible to connect the main and remote radio units with a microwave link, thereby offering operators greater flexibility. In the tests, conducted at the Ericsson premises in China, the microwave connection between the main unit and the remote unit was provided by a MINI-LINK PT, working in the E-band (70–80GHz).
Ola Gustavsson, Head- Product Line Microwave and Mobile Backhaul at Ericsson said, "In situations where optical fiber isn't the best option due to cost or time to market, it is great that we now have an alternative - in the form of microwave - that will allow operators to connect the main and remote radio units in their networks. Making it easier for operators to do business is our primary business."
