Evolved High-Speed Packet Access (also known as: HSPA Evolution, HSPA+, I-HSPA or Internet HSPA) is a wireless broadband standard defined in 3GPP release 7.
Evolved HSPA provides HSPA data rates up to 42 Mbit/s on the downlink and 22 Mbit/s on the uplink with MIMO technologies and higher order modulation. MIMO on CDMA based systems acts like virtual sectors to give extra capacity closer to the mast. The 42Mbit/s and 22Mbit/s represent theoretical peak sector speeds. The actual peak speed for a user closer to the mast may be about 14Mbit/s. At cell edge and even at half the distance to the cell edge there may only be slight increase compared with 3.6 Mbit/s HSDPA unless a wider channel than 5MHz is used. The total cell increase in capacity compared with 7.2 Mbit/s HSDPA may be as little as 20% unless very small cells with N=12 or higher reuse of channels is deployed due to CDMA code noise.
Evolved HSPA also introduces an optional all-IP architecture for the network where base stations are directly connected to IP based backhaul and then to the ISP's edge routers. The technology also delivers significant battery life improvements and dramatically quicker wake-from-idle time - delivering a true always-on connection. Evolved HSPA should not be confused with LTE, which uses a new air interface.
Several trials are underway and the first commercial launches have been announced for late 2008.

[edit] Evolved HSPA specifies all-IP architecture
An all-IP architecture is an option within Evolved HSPA. Base stations connect to the network via standard gigabit ethernet to the ISP's edge routers connected to the internet or other ISP via peering arrangements. This makes the network faster, cheaper to deploy and operate.
However the legacy architecture is still possible with the Evolved HSPA. This 'flat architecture' communicates 'user plane' IP directly from the base station to the GGSN IP router system, using any available link technology. It is defined in 3GPP TR25.999. User IP data bypasses the Radio Network Controller (RNC) and the SGSN of the previous 3GPP UMTS architecture versions. This is a major step towards the 3GPP Long Term Evolution (LTE) flat architecture as defined in the 3GPP standard Rel-8. You could say that the flat architecture makes the base station into an IP router. It connects to the Internet with cost effective modern IP link layer technologies like Ethernet, and for user plane data it is not tied to the SONET/SDH infrastructure or T1/E1 lines anymore.
Internet HSPA or I-HSPA is Nokia Siemens Networks product concept implementing Evolved HSPA. [1]
[edit] Deployment
- On 10 June 2008 Australia's Telstra Next G network was the first to enable some features of HSPA+.[2]
- On 5 December 2008, the first 21 Mbit/s (downlink) and 5.8 Mbit/s (uplink) data link was established on a commercial network (Telstra).[3]
- On 23 October 2008, the first wireless data devices for the HSPA+ standard were announced. The devices, developed by Sierra Wireless in collaboration with Netcomm,[4] Telstra, Qualcomm, and Ericsson, offer peak download speeds of 21 Mbit/s over Telstra’s Next G network – three times faster than currently available HSPA modems.[5]
- Telecom in New Zealand have also announced its use.[6]
- AT&T Mobility has hinted at using HSPA+ as a bridge standard prior to launching LTE.[7]
- On 2 December 2008, PCCW, the largest telecommunications company in Hong Kong publicly demonstrated their "PCCW NextGen Network" based on HSPA+ technology. The company will market its new HSPA+ network together with next generation gigabit fiber landline internet service in a bundle, and products are scheduled to be released to the mass market in early 2009.[8]
- On 8 January 2009, StarHub, a telecommunication provider in Singapore, commenced the upgrade of its mobile broadband network to HSPA+, following a successful live demonstration of its capability to deliver 21 Mbit/s on the downlink. This is 1.5 times higher than its current network capacity of 14.4 Mbit/s. By 2Q-2009, StarHub’s mobile broadband network will be HSPA+ ready for commercial rollout nationwide.[9]
- In June 2009, Telecom Italia, the biggest Italian provider, plans to cover the city of Milano with HSPA+, with Ericsson as the technological partner.[10]
- On 17 February 2009, during the Mobile World Congress in Barcelona, O2 Germany unveiled the start of a HSPA+ trial in Munich, Germany in summer 2009. The friendly user test[clarification needed] should provide 28 Mbit/s on the downlink and 5.76 Mbit/s on the uplink.[11]
- On 23 March 2009, Austrian mobile operator A1 - mobilkom austria started a commercial HSPA+ Network in europe. [12]
- On 30 March 2009, CSL Limited, Hong Kong’s leading mobile operator, unveiled the first commercial launch of HSPA+ in Hong Kong, provided up to 21 Mbit/s on the downlink and offers the widest coverage providing unrivaled mobility and performance..[13]
- On 04 April 2009, Dialog Telekom, Sri Lanka's largest current HSPA provider announced its update to HSPA+ will be completed soon. And now they are implemented a test network in Colombo
- On 4 June 2009, the president of DAVE Wireless, a future wireless provider in Canada, revealed that the company would be deploying a HSPA+ network covering several major cities in the country. [14]
- On 27 June 2009, Vodafone Portugal launched a HSPA 64QAM service at 21,6 Mbps. Two days later Optimus and TMN also lunched the same service in Portugal
