High Speed Packet Access Solution
New IP-based mobile used by more people in their daily communications
Delivery of digital content over mobile networks, as well as IP-based person-toperson communication that combines different media and services into a single session, will generate additional traffic and revenue. The volume of data bits used in communications will grow faster than revenue, driving operators to optimize their networks to support the dominant traffi c type. While downlink optimization is enough for content-toperson services, real interactive and person-to-person IP-based services require uplink optimization as well.
In the Nokia High Speed Packet Access Solution two key technologies, HSDPA (High Speed Downlink Packet Access) and HSUPA (High Speed Uplink Packet Access), offer breakthrough data speeds – theoretically up to 14.4 Mbps in downlink and up to 5.8 Mbps in uplink respectively – clearly higher than the most advanced 3G networks. For users this means shorter service response times and less delay.
