Nokia Siemens Networks has demonstrated at Mobile World Congress in Barcelona, Spain HSPA+ which stretches what is achieveable from mobile broadband further by allowing a device to utilise a new feature HSPA+ Multiflow.
HSPA+ Multiflow allows a device to use multiple paths to the network, i.e. connecting to two different base stations. This benefits those who are in that overlapping area where signal strength from one station is not able to provide decent broadband speeds and the other base station can cause interference.
The feature is expected to be standardized by mid 2012, and while only prototype USB dongles were used in the demo we can expect to see new dongles on the market supporting the standard. Three entered the UK HSPA+ arena in 2011 with the launch of its MiFi mobile dongle.
