Ericsson today announced that it has devised a way to triple the upload speeds across HSPA networks by making some alterations to how base stations handle such traffic. Ericsson said that a new set of software algorithms allows it to surpress the interference that WCDMA/HSPA base stations have to deal with on the uplink. Using the interference suppression technique in combination with configuring base stations with four antennas allows it to triple uplink speeds from 4Mbps to 12Mbps for a given 5MHz carrier. Ericsson says that this technique will not require network operators to invest in new base station equipment other than software updates and additional antennas. The solution works with existing consumer cell phones.
