2.3. HSxPA technology (High Speed Packet Access)
High Speed Download Packet Access and High Speed uploď Packet Access are an
improved and extended version of the UMTS-TDD. HSDPA/HSUPA is available for both
UMTS FDD and for UMTS TDD. HSDPA/HSUPA raises significantly bit rate for downlink. It is
attained on the programmer level. It doubles capacity on BTS (Base Transceiver Station),
which allows process of data and signals from more users at one time. HSDPA/HSUPA are
based on a few innovations of network architecture; thanks to this, it has lower latency, faster
reaction on channel change quality and processing of H-ARQ (Hybrid automatic repeat
request) on transmission repeat. Transport channel for HSDPA/HSUPA effectively uses
available frequencies, on which transmits data packets together. Afterwards these packets
are divides between individual users according to specific algorithms.
