What is HSPA?
HSPA supports increased peak data rates of up to 14 Mbit/s in the downlink and 5.8 Mbit/s in the uplink. It also reduces latency and provides up to five times more system capacity in the downlink and up to twice as much system capacity in the uplink, reducing the production cost per bit compared to original WCDMA protocols. HSPA increases peak data rates and capacity in several ways:
- Shared-channel transmission, which results in efficient use of available code and power resources in WCDMA
- A shorter Transmission Time Interval (TTI), which reduces round-trip time and improves the tracking of fast channel variations
- Link adaptation, which maximizes channel usage and enables the base station to operate close to maximum cell power
- Fast scheduling, which prioritizes users with the most favorable channel conditions
- Fast retransmission and soft-combining, which further increase capacity
- 16QAM (Quadrature Amplitude Modulation), which yields higher bit-rates
HSPA has been commercially deployed by over 200 operators in more than 80 countries.
