Research on HSPA – Telecommunications

Introduction

0G

The 0G technology can be referred to the first codeless telephony which is used in the

Police cars. The mobile telephone was mounted in the car near the driver usually. The

transmitter was mounted in the truck of the vehicle.

1G

The 1G was introduced in 1980’s. This is the next of the 1st generation technology. NMT

(Nordic Mobile Telephone), AMPS (Advanced Mobile Phone System) are the stands

used by the 1G. This technology is also help in the mobile telephony as used in the 0G.

But the main different is 0G is analog and the 1G is digital.

Sameer Shah (2003). An approach to - Communication Era. United States: Embin Technologies . 2p-10p.

2G

The second generation technology was used after the 1st generation. In this technology

the email, data or the software cannot be able to transfer. Only the voice and the SMS

can be transferred using the 2nd generation.

There are TDMA-based and CDMA based standards depending on the multiplexing

used.

2G technologies can be divided into TDMA-based and CDMA-based standards

depending on the type of multiplexing used. The GSM, IDEN comes under the 2G.

2.5G

The 2.5G is the stepping between 2G and the 3G. But 2.5G is not officially declared by

the International Telecommunication Union and 2.5G was named for the marketing

purpose only (funsms.net). This technology uses the same infrastructures which are

used for the 2G. So this made the service providers to switch from 2G to 2.5G easily.

Syed Ammar Faheem (2005). Evolution of 2.5G Radio Access Network towards the Prospects of high Speed Downlink Packet Access . UAE: National University of

Computer & Emerging Sciences. 2p-5p.

Currently EDGE, GPRS and CDMA2000 are using the 2.5G.

3G and 3.5 G

The third generation technology was another milestone in the telecommunication field.

The GSM EDGE, UMTS, and CDMA2000 and Wi-MAX use this technology.

The third generation technology gives many services such as voice telephone service,

the Video calls, and the wireless data transfer. This is faster than the previous

technologies implemented before. This can be go up to 5Mbps. The HSPA uses 3G and

it can reach the highest fast.

AT&T states that they are providing the speed of 20Mbps using the 3G this year. So this

may be the fastest speed which can be accessed using the 3G.

Research on HSPA – Telecommunications

HSPA

HSPA is a technology upgrade to a UTMS network that provides high speeds, capacity

and efficiency. HSPA improved spectrum efficiency enables much faster downstream.

HSPA can provide up to seven times higher than the UTMS networks. And higher

capacity, reduced delay time,

Figure 1 – Evolution of HSPA

HSPA is the next step of the life cycle of UMTS. (Universal Mobile Telecommunication

System).This is mostly used in Europe the software technologies used by the UMTS is

in a lower standard than the HSPA. And with the increasing demand for the UMTS

technology they developed the existing technology into HSPA. Even though they

upgraded this software both UMTS and the HSPA uses the same frequency range. The

phones that use the UMTS technology are extremely portable.

5

Page 6: Telecommunications - Research on Mobile Broadband HSPA/HSPDA

Research on HSPA – Telecommunications

This means that even though they are not in a coverage range of UMTS they will

connect into a GPRS or GPS network. So the users will have the facility of roaming.

Since HSPA is an updated version of UMTS it has all these facilities of UMTS as well as

more advanced and upgraded technologies. HSPA provides a smooth evolutionary path

for the UMTS networks to higher data rates and higher capacities.

Compared to UMTS HSPA can transfer larger files and it has faster web browsing. More

over HSPA offers latency as low as 70 to 100 milliseconds (ms) making it ideal for

Virtual Private Network and other real time applications. But UMTS does not have a low

latency as above and therefore it is not ideal to real time applications.

Figure 2 – Evaluation of HSPA

The above picture represents the time line of HSPA. It shows how HSPA developed

throughout the last few years. When HSPA was introduced in year 2002 it did not have

6

Page 7: Telecommunications - Research on Mobile Broadband HSPA/HSPDA

Research on HSPA – Telecommunications

a high download speed but throughout the years it developed and now it has more than

10Mbps downlink speed. According to the above picture the downlink speed will double

every year on average. It to be expected that in year 2011 the download speed will

develop up to 100Mbps.

So currently mobile service providers are moving to provide HSPA solutions to end

customers because it’s profitable and the low cost in HSPA to provide a one MB of file.

Figure 3 – Cost comparison in R99 and HSPA

The following chart shows the cost that should spend by a mobile service provider to

deliver a 10MB though R99 old technologies and HSPA. So we can see that with a

really low cost HSPA can provide its services.

Technology used

According to Ericsson there are two main combined technologies which enable to make

the data transfer in HSPA faster and effective than the previous ones. These

technologies are the main reason to the evolution of HSPA. We know that UMTS is the

beginning of the HSPA. When the technologies get the HSPA was introduced to the

market.

Multiple input multiple output antenna technology

Multi carrier technologies

Multiple input multiple output (MIMO) antenna technology

According to the Ericsson MIMO is an antenna technology for wireless communications

in which multiple antennas are used at both the source (transmitter) and the destination

(receiver).

A. Pauraj, R. Nabar and D. Gore. Introduction to Space-Time Wireless

Communications. Cambridge University Press, Cambridge, 2003.

This is efficient because in this method the transmitter as well as the receivers have

multiple antennas. Also comparing other technologies the data exchange rate is very

high.

Page 9: Telecommunications - Research on Mobile Broadband HSPA/HSPDA

Research on HSPA – Telecommunications

Multi carrier technologies

According to whatis.com Multi-carrier modulation (MCM) is a method of transmitting

data by splitting it into several components, and sending each of these components

over separate carrier signals.

In multi carrier technology the frequency goes normally in two channels; so that the

download speed can be doubled. If the normal one channel has the download speed as

5Mbps using this technology will make the speed into double.

Ericsson says that they can make antennas and devices which can be able to access the data up to 42Mbps. They provide 21Mbps devices recently and they promise that can be able go up to the double.

Importance

Speed

HSPA solution can deliver up to 14Mpbs downlink and 2mpbs uplink speeds which are

really better than GPRS and EDGE speeds. So as a mobile broadband solution HSPA

is a good technology that can provide higher uplink and downlink speeds.

Cost effective

With HSPA cost is really low in implementation and delivering the network .for example

if we consider about delivering a 10Mb file with HSPA and UTMS Release 99 with

HSPA it will be really cheap. So telecom providers and give broadband solutions for

customers in a very low cost. Also HSPA provide higher quality services at the lowest

cost.

Mobility

HSPA is a mobile broadband service which can provide high speed internet access with

mobility, so not like DSL and Wi-MAX technologies; HSPA is a full mobility way of

providing internet to the end customers. So users and use the technology any time

anywhere.

10

Page 11: Telecommunications - Research on Mobile Broadband HSPA/HSPDA

Research on HSPA – Telecommunications

Considerations before implementation

HSPA solutions can be implemented on a 3rd Generation or 2nd Generation GSM

Network but the Network should be updated to 3.5 generation.

To upgrade to a higher GSM generation the telecom companies may need technical

support and hardware implementations on the current network infrastructure. The areas

that should be implementing HSPA should be covered with a 3.5G GSM signal

coverage.

To give the maximum throughout out to the customers the area should be well covered

well if not the signals will be dropped and customers will experience low speeds. Also

the telecom company should select which is the best HSPA type they should implement

with the conditions. So they have to find the best technology suitable and best places to

implement the transmission towers.

11

Page 12: Telecommunications - Research on Mobile Broadband HSPA/HSPDA

Research on HSPA – Telecommunications

Criteria required implementing the technology

When implementing a new technology we have to consider about all the facts such as

what are the hardware and software requirements we need, what are the skills needed,

how much it will cost to implement such a technology and many more.

The following skilled people are qualified to implement a HSPA technology

Senior RF Systems Engineer

Senior Systems Applications Engineer

Technical Applications Engineer

Technical Application Engineer

Senior Software Engineer

Cab mobile designer Engineer

Senior Test Engineer(Software bias)

3G / Wireless Protocol Stack Software Developer

Telecoms Product Implementation Engineer

Field Engineers

Telecom Design Engineer

System Engineer

In addition to their own qualifications all of the above engineers should be specialized in

Wireless field engineering.

Lucent Tecnologies (2005). High-Speed Downlink Packet Access . Asia Pacific : Lucent Technologies.

12

Page 13: Telecommunications - Research on Mobile Broadband HSPA/HSPDA

Research on HSPA – Telecommunications

Software Requirements

In addition the major important fact we need to consider when implementing a

technology is the security of data. The developers have to maintain a higher standard of

security, there for the developers should have a vivid knowledge about implementing

such a technology as well as a higher knowledge on how to maintain a higher standard

of security so that the outsiders will not be able to access the company data.

Moreover the developers should maintain a database to store the details of the

customers as well as their account information. In addition the developers should have

a vivid knowledge on how to design and implement new protocols.

13

Page 14: Telecommunications - Research on Mobile Broadband HSPA/HSPDA

Research on HSPA – Telecommunications

Cost

To the upgrade the infrastructure telecom company should have good financial status

because investing on a network upgrade will be really costly.

In Sri-Lanka yet the HSPA is implemented by only 3 mobile services providers who has

good financial backup. Dialog Telecom, Baharathi Air Tel, Sri-Lanka Telecom Mobitel

are the current HSPA services providers in Sri-Lanka. Telecom providers like Hutch are

not interested in implementing HSPA because they can’t bear the large cost on

infrastructure update.

Upgrade of the GSM network

If a telecom carrier is already providing GSM 2G mobile services they can upgrade to

3G mobile network but it’s not a simple procedure .With the 3G implementation many

new hardware should be deployed in the current telecom infrastructure. Especially base

stations should upgrade with more complex protocols,

 

Too many options

There are many options available for Telecom providers when upgrading to a 3G

network on base station implementation .they have to choose the correct specifications

when they upgrade.

They have to choose the correct codec’s, modulation schemes to get the best though

output.

Increasing complexity

With the HSPA implementation the network infrastructure get complex.

Implementation

HSPA technology is based on UMTS networks and its use GSM third Generation as its

core .HSPA can use GSM third generation base stations to distribute the signals. The

base station known as Node b is responsible to handles network traffic and the users of

the network.

Node B

According to Lucent Technologies Node b is a radio signal base transfer station. Node b

contains radio frequency transmitters and the receivers to provide the services to

customers.

Figure 4 – Structure of a Node B

The figure above shows the structure of a Node B which has the radio cabinet and the

power cabinet.

Radio Network Controller

According to Lucent Technologies Radio Network controller (RNC) mainly controls the

node B .Radio recourse management and functions like load controller, security

functions like encryption, packet scheduling, is done by RNC.

HSPA technology is based on UMTS and its use GSM third Generation as its

core .HSPA can use GSM third generation base stations to distribute the signals. The

base station known as Node b is responsible to handles network traffic and the users of

the network.

HSPA is mainly implementing on the Node B and RNC (Radio network controller).most

of the key processing is done in the base station so it will minimize the network delays.

With HSPA it introduces a new transpiration channel called the HS-DSCH (High Speed

downlink shared channel).

HS-DSCH

In Nokia whitepaper they describes that High Speed downlink shared channel is a

downlink transport channel. HS-DSCH can be transmitted over the cell using beam-

forming antennas.

HSPA will also use following g error control and encoding methods in implementation.

Modulation schemes

Mainly HSPA use (Quadrature Phase Shifting keying) QPSK modulation for download

transmission and to achieve higher data rates 16 Quadrature Phase Amplitude

modulation (16 QAM) is been used.

Network implementation

The following network diagram shows a simple GSM network implementation which a

HSPA technology can be implemented. The mobile switching centre is connected to the

Base station controller and it connected to the base transfer controller in each cell, Also

the visitor location register connects to the cells. The authentication centre and the

Home location register are connected to the Mobile switching centre.

Page 27: Telecommunications - Research on Mobile Broadband HSPA/HSPDA

Research on HSPA – Telecommunications

Advantages and Strengths

The round trip time between the network and the terminal is reduced

Since there is a more sophisticated scheduling it allows for favorable allocation of

resources.

A four-fold increase in the network capacity.

Peak data rates of seven times higher than those in the most advanced

networks.

HSPA has an improved bandwidth efficiency which enables faster between

network and the terminal than the other technologies.

Enables operators to significantly increase capacity in a cost effective manner.

Has the ability to seize the market in a profitable project sector.

The cost to deliver a file will be less when compared with GPRS

Provides re-transmission mechanism for faster error correction.

27

Page 28: Telecommunications - Research on Mobile Broadband HSPA/HSPDA

Research on HSPA – Telecommunications

Since HSPA is using a technique called Adoptive Modulation and Coding (AMC)

it maximizes the capacity and ensures that all users benefit from the best

possible data rate.

Minimizes transmission delays.

Round trip time means the overall time it takes for data to travel back and forth between

the terminal and the network. Therefore the overall time will be reduced and thus the

speed will also increase. Since the overall round up time is reduced and the bandwidth

is high it will minimize in transmission delays as well as faster error correction. Since the

cost to deliver a file is less when compared to GPRS it will be a huge benefit for the

user. Because then they can save their money.

HSPA is an extremely cost-effective path to higher data rates and provides more

efficient use of valuable spectrum .Since the users has the benefit of accessing to

sophisticated mobile IP multimedia services it’s a massive advantage for them because

earlier they could not access such services.

28

Page 29: Telecommunications - Research on Mobile Broadband HSPA/HSPDA

Research on HSPA – Telecommunications

Disadvantages and problems

The HSPA and the R99/4 service cannot share the same carrier frequency

resources effectively. Because of this the system requires a switch in the system

band so it increases the delay time.

HSPA suffers from cell breathing.

HSPA has a theoretical speed limit of 14.4Mbps which means that WiMax will be

a serious competitor for HSPA.

Its charging for the data downloaded

There is a limitation to download data

Wi-Max has a 70Mbps with a range of close to 30 miles all from just a single base

station. But the theoretical speed limit of HSPA is said to be 14.4Mbps, so WiMAx

can be a huge competitor for HSPA this is a main disadvantage HSPA faces at the

moment. Another point is that HSPA technology charges for the amount of data that

has been downloaded during a month or a week; this downloaded data includes the

loading of web pages so this is a disadvantage to the users because they have to

pay money to the uploading of web pages too. Moreover there is a limitation to the

amount of data that can be downloaded and if the user exceeds this specific amount

of data the connection will be very slow. Cell Breathing means that there will be

interference between the users in the same cell and the neighboring cells,

consequently this will be a disadvantage because then the connection will not be

clear and it will take a longer time to download or upload data

29

Page 30: Telecommunications - Research on Mobile Broadband HSPA/HSPDA

Research on HSPA – Telecommunications

Affect on the Human Beings

With the development of the technologies it has been having a good affect on the

human beings because their day to day activities are becoming easier. The phones that

use the UMTS and HSPA technologies has the ability to connect to a GPTS or GSM

network when they are not in a coverage range of UMTRS or HSPA. The users will

have the advantage of transferring higher data rates.

Furthermore the overall response time will be less due to the fact that a higher capacity

of data can be transferred within a short time. Moreover the users can experience a

better and improved availability of services. Accordingly the users will experience a

better quality of services. As well there are some bad effects on human beings too.

Because of the cell breathing the download and the upload speed can be slower and

the overall waiting time will increase. Another point is that after exceeding the limit the

connection can be slower this too will increase the overall waiting time.

QoS in HSPA

Quality of service in HSPA is hard to define it depend on several things. Specially if you

don’t get the indoor singles properly or if the service provider doesn’t provide any good

indoor coverage the Quality of service in really poor .Also there are several factors that

QoS in HSPA is depend on that is network traffic and network capacity, in high peak

when the network traffic is really high the uplink will be get slower.

Future of HSPA

As we stated above, the HSPA is the next of the UMTS. The subscribers of the HSPA

are being growing daily. This may be because of the high speed internet access in

HSPA handsets; HSPA provides better user experiences in multimedia applications.

Also HSPA is being popular because of the cheap of the hand sets.

Then earlier days HSPA had its download speed as 384Kpbs and the upload speed

20Kpbns Now the speed of the download has grown up to 14.4Mpbs and also the

upload speed also has grown up to 2.3Mpbs also the download speed as well as the

upload speed will increase further in future.

Now days the mobile network providers are intending to increase their service speed as

the speed increasing of the devices. Vodafone say that most customers get the highest

speed as the 5 Mbps though the are connected to the base station of 14Mbps. So the

Vodafone are working to reach the highest download speed to 14Mbps to give the

benefit to the customers.

The new laptops have been introduced. These laptops has inbuilt HSPA. They have a

SIM card slot also. The Dell with the coloration of Sony Ericson has been introduced.

31

Page 32: Telecommunications - Research on Mobile Broadband HSPA/HSPDA

Research on HSPA – Telecommunications

Figure 12 - Sony Errcsion phone with built in HSPA capabilities

We hope that in future the HSPA will be used in land phones as well as the CDMA

phones. Now day’s people use telephone connection or CDMA phones or a separate

dongle to access the internet. But in near future all land phones will be included a SIM

card slot so that the users can connect their SIM card and they can connect the

telephone to the computer. This will make the users to access to the internet.

Also we can introduce anther technology for the vehicles. The HSPA can be attaching

to the car and every time the HSPA can be able to send the signal to the base station

mentioning place where it is, as usually the other mobile SIM providers do; so that the

owner of the particular vehicle in case if the car was stolen. Currently in Sri Lanka they

use this techno by attaching the mobile phone.

Some of the new technologies in HSPA is based on WCDMA evolution standardized as

part of 3GPP Release 7 WCDMA specifications. The following technologies will be help

the future development in HSPA.

Conclusion

The basic requirement for HSPDA is to carry high data rate on the downlink. HSDPA is

an extremely cost effective path to higher data rates. It has a wide range of coverage

and the users have the benefit of connecting to other networks if they are not in a

coverage area of HSPDA. In summery it means that the phones that users HSPDA are

extremely portable. The most important thing about HSPDA is that it reduces the overall

round trip delay and thus the users has the advantage of downloading or uploading data

faster. Moreover the peak data rate of HSPDA is increased up to 14Mbps.The primary

target of HSPDA is to enhance system throughput with minimum changes in network

architecture in addition the motivation behind HSPDA is to support sophisticated UE

applications which needs higher bit rates.
