HSPA

HSPA (High Speed Packet Access) is like having the home cable broadband experience delivered to the mobile phone or notebook. HSPA is part of the GSM 3G network and is (predominately) a software upgrade of the network infrastructure. To use the high speed variant, it is necessary to have a mobile device that is HSPA-enabled – most new mobile phones and high-end notebooks only have these as standard. Belonging to the family of GSM, It is the latest technology to enable even faster data rates for mobile users. It has various enhancements on its route. Firstly, HSDPA ( High Speed Downlink Packet Access) has the capability to take delivery of bulky files to the mobile device such as email attachments, PowerPoint presentations or web pages. HSDPA 3.6mbps network can download a typical music file of around 3Mbytes in 8.3 seconds and a 5Mbps video clip in 13.9 seconds. Speeds achieved by HSDPA top 14.4Mb/s but most network operators provide speeds up to 3.6Mbps, with the rollout of 7.2Mbps quickly growing. HSUPA (High Speed Uplink Packet Access) is a further enhancement that helps in increasing the speed by which one can communicate from the mobile device, for example one can easily upload videos from UTube within a few seconds. Here the upload speed is increased to a maximum of 5.7Mb/s. HSPA Evolved which is also known as HSPA+ delivers data services, permit speed of up to 42Mb/s in the downlink and 11Mb/s in the uplink.
