What is HSUPA?
HSUPA (HIGH SPEED UPLINK PACKET ACCESS)
High Speed Uplink Packet Access (HSUPA) is a UMTS / WCDMA uplink evolution technology currently being standardised in 3rd Generation Partnership Project (3GPP); HSUPA is expected to be standardised by the 3GPP in UMTS Release 6.
The new HSUPA mobile telecommunications technology is directly related to HSDPA and the two are complimentary to one another. It seems that HSDPA is the more advanced of the two technologies, but when they can function side-by-side the resulting system will benefit with major data transfer speed enhancements for receiving or sending.
Both procedures resemble each other technically and, by the employment of special modulation procedures, allow a better use of the net infrastructure. The power spectrum of the UMTS network may be enhanced at relatively small expenditure. Improved intensive data services can then be offered. Thus HSUPA opens further areas for innovations and new business possibilities.
HSDPA and HSUPA both offer high voice and data performance and together will enable the success of mass-market mobile IP multimedia. HSUPA enhances the uplink speed of UMTS / WCDMA networks and is the next step after HSDPA.
HSUPA will enhance advanced person-to-person data applications with higher and symmetric data rates, like mobile e-mail and real-time person-to-person gaming. Traditional business applications along with many consumer applications will benefit from enhanced uplink speed. HSUPA will initially boost the UMTS / WCDMA uplink up to 1.4Mbps and in later releases up to 5.8Mbps.
