HSPA - Mobile Broadband Today

HSPA--High Speed Packet Access

HSPA is part of the GSM 3G network and is (predominately) a software upgrade of the network infrastructure. To use , you need

a mobile device.

HSPA has a great legacy, coming from the GSM family. It is the latest technology to enable even faster data rates for mobile

users available today. The evolution has seen familiar acroymns such as GPRS (the first packet technology giving around

128kb/s) to EDGE (an enhanced version offering around 240kb/s) and then the introduction of 3G networks increasing the data

rate to 384kb/s.

The various enhancements on the HSPA route are as follows:

HSDPA – High Speed Downlink Packet Access
– the ability to receive large files to your mobile device such as email attachments, PowerPoint presentations or web pages.

HSUPA – High Speed Uplink Packet Access – this is a further enhancement to increase the speed by which you communicate from

your mobile device. The upload speeds which were at 384kb/s with HSDPA are now increased to a maximum of 5.7Mb/s

HSUPA is available in a few countries today with 2008 really seeing this as common place.

HSPA Evolved – this is also known as HSPA+ is the next step and is more focused on delivering data services enabling

speeds of up to 42Mb/s in the downlink and 11Mb/s in the uplink. HSPA Evolved will be available in late 2008 early 2009.

All of these are acronyms mean Mobile Broadband, today!

Common terms used by mobile network operators to market the service are: 3G+, NextG, 3G Broadband, 3.5G and many

more. As Sri Lankans we faced this marketing showers...[Mobitel Vs. Dialog]


High-speed packet access (HSPA) and not WiMax is set to dominate mobile broadband in the coming years -- if hardware makers

get behind the technology.

A report by analyst Juniper Research predicts 70 percent of mobile-broadband subscribers will use the souped-up version of 3G

by 2012. Total mobile-broadband subscribers will number 1.2 billion by then, it said -- equivalent to nearly one in three

mobile subscribers worldwide.

HSPA -- high-speed packet access -- delivers mobile broadband speeds in excess of 500Kbps, and up to several Mbps. There are

currently around five million HSPA subscribers worldwide, according to international 3G advocate the UMTS (Universal Mobile

Telecommunications Services) Forum.

so guys you know now that HSDPA is years ahead of HSCSD

HSCSD (High Speed Circuit Switched Data) is a specification for data transfer over GSM networks. HSCSD utilizes up to four

9.6Kb or 14.4Kb time slots, for a total bandwidth of 38.4Kb or 57.6Kb.

14.4Kb time slots are only available on GSM networks that operate at 1,800MHz. 900Mhz GSM networks are limited to 9.6Kb time

slots. Therefore, HSCSD is limited to 38.4Kbps on 900Mhz GSM networks. HSCSD can nly achieve 57.6Kbps on 1,800Mhz GSM

networks.
