HSDPA stands for High-Speed Downlink Packet Access. It is also referred to as 3.5G technology in mobile protocol. Installation of the HSDPA feature in cell phones can provide higher speed of data transmission during a downlink process.

It is promoted primarily for mobile phone access to the Internet in the same way as DSL is for residential access. Users get more pieces of data in a shorter time. With that, providers can catch more users to create more revenue.

This innovation in telephony is an upgrade of the WCDMA, an improvement in cellphone broadband data service. It is capable of increasing the capacity of a system. It allows service providers to offer more competent services through the same wireless delivery service frequency used by WDCMA. The projected effects have been viewed as a win-win solution for both the end-users and the providers of data service.

What Users can Expect

With the speed of data transfer reaching up to a peak rate of 14,400 kbps, HSDPA brings a better experience for its end-users. Data will have a shorter time to travel; the higher the Transmission Time Interval (TTI), the faster the downloading time is. As data comes more rapidly, the cost of access will be reduced too. If HSDPA will be made available to a wider market of mobile phone users, stalling on downloads will be a thing of the past.

Benefits to the Operator

Production costs will be greatly reduced because of the intensified system capacity. Through the process called shared channel transmission, there will be no need for operators to install a new set of carriers. It will use the existing spectrum of data and voice carriers currently used by the technology versions in operation.

HSDPA handles faster retransmission to facilitate an increase in capacity. Another remarkable aspect of the HSDPA feature is its fast scheduling rate, giving priority to users who have the most advantageous channel conditions.

As data will come faster, many end-users will be serviced at a higher speed. Hence, the service can be extended to a wider market.

HSDPA will continue to evolve over time as special upgrades are always introduced. However, it still requires more refinement to make it an alternative to the current 3G technology, which has delivered short of its promised efficiency.
