 Nokia - Nokia launches Internet High Speed Packet Access - Press Releases - Press - About Nokia
Also at CTIA Wireless, Nokia is demonstrating HSUPA (High Speed Uplink Packet Access), a UMTS/WCDMA uplink evolution technology currently being standardized in 3GPP, in addition to HSDPA (High Speed Downlink Packet Access).
Nokia further expands its wide radio access offering, demonstrates High Speed Uplink Packet Access (HSUPA), and expresses commitment to EDGE evolution.
HSDPA and HSUPA offer high voice and data performance and will enable real mass-market mobile IP multimedia.

 High-Speed Downlink Packet Access - Wikipedia, the free encyclopedia
High-Speed Downlink Packet Access (HSDPA) is a new mobile telephony protocol and is sometimes referred to as a 3.5G (or "3½G") technology.
HSDPA defines a new W-CDMA channel, the high-speed downlink shared channel (HS-DSCH) that operates in a different way from existing W-CDMA channels, but is only used for downlink communication to the mobile.
HSDPA is part of release 5 UMTS networks, which also accompanies an improvement on the uplink providing a new bearer of 384kbps (previous max bearer was 128kbps).

 High-Speed Uplink Packet Access - Wikipedia, the free encyclopedia
Similar to HSDPA (High-Speed Downlink Packet Access), HSUPA is considered 3.75G.
In HSDPA and other downlink technologies the transmitter is at the base station and its power supply is not limited in time, but more importantly the dynamic range of its amplifier is inherently greater, which made the choice of higher-order modulations more attractive.
Similarly to HSDPA there will be a packet scheduler, but it will operate on a request-grant principle where the UEs request a permission to send data and the schedular decides when and how many UEs will be allowed to do so.

The carrier is also considering High Speed Uplink Packet Access (HSUPA), which boosts the upload speed from the cell phone to the network, in 2007 or 2008.
Cingular's service provides download speeds of 400 kbps to 700 kbps and is accessible via a laptop modem card for a flat rate of $60 per month.
Services can apply HSDPA to third-generation Wideband Code Division Multiple Access (WCDMA) networks to offer significantly faster data downloads.

 High-Speed Packet Access Opens the Door to Turbo 3G
HSDPA (high-speed downlink packet access) and HSUPA (high-speed uplink packet access) are the first steps down this road for UMTS-based 3G systems.
"Mobile broadband has the potential to be a major new growth area for mobile operators as they start to compete with public wireless LAN and residential broadband access services," says Gabriel Brown, Chief Analyst of Unstrung Insider and author of the report, entitled Turbo 3G: High-Speed Packet Access Arrives.
Brown analyzes the implementation of these high-speed upgrades to mobile networks worldwide and assesses the impact of this disruptive technology on the mobile infrastructure market.

 4G tests successfully made
Japan's DoCoMo says that high-speed packet transmission with 1 Gbps data rate in the downlink was achieved successfully in a laboratory experiment using fourth-generation (4G) mobile communication radio access equipments on August 20, 2004, considering field experiments in the early next year.
DoCoMo achieved 100Mbps and 20Mbps data rate transmission in the downlink and uplink, respectively, in the outdoor environments with the moving speed of about 30 km/h in July 2003.
The implemented 4G radio access equipments employ variable-spreading-factor spread orthogonal frequency division multiplexing (VSF-Spread OFDM) radio access method and multiple-input-multiple-output (MIMO) multiplexing technique using new signal detection algorithm in order to achieve 1Gbps data transmission with 100MHz bandwidth in the downlink.
