What is HSUPA (high speed uplink packet access)?

High-Speed Uplink Packet Access (HSUPA) is a 3G portable communication protocol in the HSPA. It was determined and normalized in 3GPP Release 6 to further develop the uplink data rate to 5.76 Mbit/s, expanding the limit, and diminishing latency. HSUPA has been supplanted by more up to date technologies further advancing transfer rates. LTE gives up to 300 Mbit/s for downlink and 75 Mbit/s for uplink.
