It’s surprising to think back and remember that when the first HSPA devices came onto the market, they offered downlink speeds of just 1.8 Mbps. Today, people can buy HSPA tablets and smartphones with download data rates of 42 Mbps. Without much fanfare, HSPA has been continuously improving and now offers top data rates and customer experience.
With HSPA predicted to be carrying the majority of traffic long into the future, developments in the pipeline promise to keep the technology at the forefront of mobile broadband for many more years with most operators, even those planning a major focus on LTE.
So what else does HSPA bring to the table besides speed? Just to name a few real user advantages: low battery consumption and reduced signaling for smartphones, increased uplink capacity and great customer experience at the cell edge, low latency for interactive data, high data rates for streaming, large coverage of macro cells, as well as high capacity for serving a large subscriber base.
Small cell benefits and other wins
New developments in standardization include improvements in the operation of networks with small cells. In the HetNets of 3GPP Release 12, special attention is given to managing the uplink budget: the network will be able to identify devices with an unbalanced uplink and take corrective action.
Other improvements in the pipeline include more efficient transmission of voice and increasing broadcast channel (BCH) capacity as well as interworking with Wi-Fi.
HSPA remains the mainstay of global mobile broadband communications, and new developments will keep the industry on its toes.
