HSPA evolution for future mobile-broadband needs
More and more people around the globe have high-speed mobile access to the internet. The growth is in part fuelled by the availability of low cost smartphones, rising use of apps that require data stored in clouds and the growing number of mobile internet connections. Nearly 80 percent of mobile subscriptions will be MBB, indicating that MBB will be the primary service for most operators in the coming years.
Ericsson ConsumerLab studied a group of people to assess how they perceived network quality and what issues they encountered when using their smartphones. The study identified two key factors that are essential to the perceived value of a smartphone: a fast and reliable connection to the data network, and good coverage.
The ConsumerLab findings highlight an important goal for operators: to provide all network users with high-speed data services and good quality voice-services everywhere.
Some of the enhancement techniques that will help to provide users with the right level of app coverage, while securing voice include: rate adaption, Lean Carrier, connected-mode, use of lower frequency bands and uplink transmit diversity.
With these enhancements, WCDMA/HSPA, already the dominant MBB and best-in-class voice technology, has a strong evolution path to meet the future demands presented by the growth of MBB and highly capable smartphones globally.
