INTRODUCTION

The first generation (1G) and second generation (2G) of mobile telephony were intended primarily for voice transmission. The third generation of mobile telephony (3G) will serve both voice and data applications.

The original analog cellular systems are considered the first generation of mobile telephony (1G). In the early 1980s, 1G system was deployed. At the same time, the cellular industry began developing the second generation of mobile telephony (2G). The difference between 1G and 2G is in the signaling techniques used: 1G used analog signaling, 2G used digital signaling. As experience shows, the lead-time for mobile phone systems development is about 10 years. It was not until the early to mid 1990s that 2G was deployed. Primary thinking and concept development on 3G generally began around 1991 as 2G systems just started to roll out. Since the general model of 10 years to develop a new mobile system is being followed, that timeline would suggest 4G should be operational some time around 2011. 4G would build on the second phase of 3G, when all networks are expected to embrace Internet protocol (IP) technology.

3G or 3rd generation mobile telecommunications, is a generation of standards for mobile phones and mobile telecommunications services fulfilling the International Mobile Telecommunications-2000 (IMT — 2000) specifications by the International Telecommunication Union. Application services include wide-area wireless voice telephone, mobile Internet access, video calls and mobile TV, all in a mobile environment. To meet the IMT-2000 standards, a system is required to provide peak data rates of at least 200 kbit/s. Recent 3G releases, often denoted 3.5G and 3.75G, also provide mobile broadband access of several Mbit/s to smartphones and mobile modems in laptop computers.

During the last year, companies such as Ericsson, Motorola, Lucent, Nortel and Qualcomm came up with “3G-plus” concepts that would push performance of approved, though still emerging, standards beyond current ones.

CHRONOLOGY

On 14 December 2009, the first commercial LTE deployment was in the Scandinavian capitals Stockholm and Oslo by the Swedish-Finnish network operator TeliaSonera and its Norwegian brandname NetCom (Norway). TeliaSonera branded the network "4G". The modem devices on offer were manufactured by Samsung (dongle GT-B3710), and the network infrastructure created by Huawei (in Oslo) and Ericsson (in Stockholm). TeliaSonera plans to roll out nationwide LTE across Sweden, Norway and Finland. TeliaSonera used spectral bandwidth of 10 MHz, and single-in-single-out, which should provide physical layer net bitrates of up to 50 Mbit/s downlink and 25 Mbit/s in the uplink. Introductory tests showed a TCP throughput of 42.8 Mbit/s downlink and 5.3 Mbit/s uplink in Stockholm. On 25 February 2010, Estonia's EMT opened LTE "4G" network working in test regime.

Sprint Nextel released the first WiMAX smartphone in the US, the HTC Evo 4G on 4 June 2010. In July 2010, Uzbekistan's MTS deployed LTE in Tashkent. Latvia's LMT opened LTE "4G" network working in test regime 50% of territory on 25 August 2010. On 6 December 2010, at the ITU World Radiocommunication Seminar 2010, the ITU stated that LTE, WiMax and similar "evolved 3G technologies" could be considered "4G". In December 2010, VivaCell-MTS launches in Armenia 4G/LTE commercial test network with a live demo conducted in Yerevan. Lithuania's Omnitel opened LTE "4G" network working in 5 biggest cities 28 April 2011.

What is 4G technology ?

When talking about 4G, question comes to our mind is what is 4G Technology. 4G is short for Fourth (4th) Generation Technology. 4G Technology is basically the extension in the 3G

technology with more bandwidth and services offers in the 3G. But at this time nobody exactly knows the true 4G definition. Some people say that 4G technology is the future technologies that are mostly in their maturity period. The expectation for the 4G technology is basically the high quality audio/video streaming over end to end Internet Protocol. If the Internet Protocol (IP) multimedia sub-system movement achieves what it going to do, nothing of this possibly will matter. WiMAX or mobile structural design will become progressively more translucent, and therefore the acceptance of several architectures by a particular network operator ever more common.

Many Technologies appear in many different flavours and have many diverse tags attached to them, but that does not really indicate that they are moving in dissimilar tracks. The technologies that fall in the 4G categories are UMTS, OFDM, SDR, TD-SCDMA, MIMO andWiMAX to the some extent.

 

4G Technology offers high data rates that will generate new trends for the market and prospects for established as well as for new telecommunication businesses. 4G   networks , when tied together with mobile phones with in-built higher resolution digital cameras and also High Definition capabilities will facilitate video blogs.

After successful implementation, 4G technology is likely to enable ubiquitous computing, that will simultaneously connects to numerous high date speed networks offers faultless handoffs all over the geographical regions. Many network operators possibly utilize technologies for example; wireless mesh networks and cognitive radio network to guarantee secure connection & competently allocates equally network traffic and bandwidth.

Some of the companies trying 4G mobile communication at 100 Mbps for mobile users and up to 1 Gbps over fixed stations. They planned on publicly launching their first commercial wireless network around 2010. As far as other competitor’s mobile communication companies working on 4G technology even more quickly. Sprint Nextel was planned to launch WiMAX over 4G broadband mobile network in United States. Some of the other developed countries like United Kingdom stated a plan to sale via auction of 4G mobile frequencies couple of years back. The word “MAGIC” also refers to 4G technology which stands for Mobile multimedia, Any-where, Global mobility solutions over, Integrated wireless and Customized services.

Objective and approach

Objectives

4G is being developed to accommodate the quality of service (QoS) and rate requirements set

by further development of existing 3G applications like mobile broadband access,Multimedia

Messaging Service (MMS), video chat, mobile TV, but also new services like HDTV. 4G may

allow roaming with wireless local area networks, and may interact with digital video

broadcasting systems.

In the literature, the assumed or expected 4G requirements have changed during the years

before IMT-Advanced was specified by the ITU-R. These are examples of objectives stated in

various sources:

A nominal data rate of 100 Mbit/s while the client physically moves at high speeds

relative to the station, and 1 Gbit/s while client and station are in relatively fixed positions as

defined by the ITU-R [21]

A data rate of at least 100 Mbit/s between any two points in the world

Smooth handoff across heterogeneous networks

Seamless connectivity and global roaming across multiple networks

High quality of service for next generation multimedia support (real time audio, high

speed data, HDTV video content, mobile TV, etc.)

Interoperability with existing wireless standards

An all IP, packet switched network

IP-based femtocells (home nodes connected to fixed Internet broadband infrastructure)

Approaches

Principal technologies

Physical layer transmission techniques are as follows:

MIMO : To attain ultra high spectral efficiency by means of spatial processing

including multi-antenna and multi-user MIMO

Frequency-domain-equalization, for example Multi-carrier modulation (OFDM)

in the downlink or single-carrier frequency-domain-equalization (SC-FDE) in the uplink:

To exploit the frequency selective channel property without complex equalization.

Frequency-domain statistical multiplexing, for example (OFDMA) or (Single-

carrier FDMA) (SC-FDMA, a.k.a. Linearly precoded OFDMA, LP-OFDMA) in the

uplink: Variable bit rate by assigning different sub-channels to different users based on

the channel conditions

Turbo principle  error-correcting codes: To minimize the required SNR at the

reception side

Channel-dependent scheduling : To utilize the time-varying channel.

Link adaptation : Adaptive modulation and error-correcting codes

Relaying, including fixed relay networks (FRNs), and the cooperative relaying concept,

known as multi-mode protocol

About the P1 WIMAX

Packet One Networks (P1)

Packet One Networks (P1) is a Malaysian converged telecommunications, broadband and Wimax service provider. The company was founded in 2002 and is a subsidiary of Green Packet Berhad. In March 2007, P1 was one of four companies awarded 2.3 GHz spectrum licenses by the Malaysian Government to deploy WiMAX services throughout Malaysia. In August 2008, P1 became the first company to launch commercial WiMAX services in Malaysia.

P1 Products and services

P1 W1MAX

P1 W1MAX is presently a fixed portable broadband service that runs on the 2.3 GHz WiMAX spectrum and 802.16e 2005 standard, which is known as Mobile WiMAX. It enables wireless broadband access up to 30 miles (50 km) from the base station.

P1 W1MAX offers three type of modems:

P1 W1MAX DS300 Shared Modem P1 W1MAX DV230 Shared Modem that integrates WiMAX, 802.11 b/g WiFi and voice

functionality into one device.

P1 W1MAX DX230 New 3-in-1 Modem that integrates WiMAX, 802.11 b/g/n WiFi and voice .

WIGGY

P1 W1MAX's On-the-Go Portable Modem is called WIGGY

P1 W1MAX offers three packages:

WIGGY 129 which has speeds up to 3 Mbit/s; WIGGY 89 which has speeds up to 1.5 Mbit/s.

Page 9: IAD 2331 Fundamental of Network - 4G P1 WIMAX

WIGGY 58 which has speeds up to 600 kbit/s

The WIGGY is also available in prepaid.

Initially, the WIGGY was advertised to offer speeds of up to 10Mbps. At the time the package was offered, it was the fastest wireless package offered in Malaysia. However this package was quickly pulled when the company received backlash after many of the subscribers found that they were unable to achieve the 10Mbps speed.

WiMAX for Embedded Devices

P1 W1MAX also offers WiMAX subscription for Intel powered Netbook and Notebooks that are WiMAX ready.

4G WiMAX Network

P1 occasionally advertises it's network as a '4G' network. However, this is primarily a marketing gimmick as WiMAX does not meet the ITU's specification of 4G which requires attaining a download speed of 1Gbps for tabletop transceivers and 100mbps for mobile transceivers. However, P1 isn't alone in this misleading marketing gimmick, two other WiMAX-based ISPs also market the technology as 4G.

The fact that the upcoming WiMAX Release 2 aka IEEE 802.16m specification does adhere to the 4G specifications and is officially recognized by the ITU as a 4G system only further adds to the confusion.

Green Packet brings WiMAX to life for P1, Malaysia’s first and leading WiMAX Operator

Packet One Networks (Malaysia) Sdn. Bhd. (P1) is Malaysia’s first and leading WiMAX telecommunications company, offering the country’s widest WiMAX network, innovating technology, products and services to advance the way people work, live, learn and play. P1 is also the first WiMAX Operator in Southeast Asia to roll out commercial WiMAX services under the 802.16e Mobile WiMAX variant.

Page 10: IAD 2331 Fundamental of Network - 4G P1 WIMAX

Malaysia’s Broadband Climate

Malaysia’s broadband penetration rate of 8.6% is relatively low compared to other Asian countries such as Singapore (19%), Korea (31%) and Taiwan (21%). As such, several initiatives were introduced by the Malaysian Government to boost the ICT arena of the nation, declaring that ICT constitutes an important component for progress.

Echoing the Malaysian Government’s goal, P1 is determined to bridge the digital divide by ensuring access to Internet is universal, ubiquitous and affordable for every Malaysian. P1 hopes to play a major part in realizing the Malaysian Government’s vision to have 50% broadband penetration by 2010, in line with the nation’s ICT plan, MyICMS 886.

The Uphill Climb for P1

Though having a strong first mover advantage, Mobile WiMAX 16e is a completely new technology to Malaysians, hence, it is important for P1 to convince and convert its prospects to long-term subscribers. To maintain its leadership position in Malaysia’s WiMAX space, it is critical for P1 to sustain the quality of its services and extend unparalleled user experience.

Additionally, the WiMAX service tendered has to be easy-to-use and affordable.

How Green Packet Rose to the Occasion

To meet the high expectations of WiMAX in terms of delivering high quality wireless broadband services and a level of user experience unmatched by any other WiMAX Operator in Malaysia, P1 chose Green Packet’s WiMAX Solutions to offer WiMAX services to residential and enterprise users in Malaysia.

Award-winning Plug ‘n Play WiMAX Modems

Green Packet extended its complete range of WiMAX Modems comprising of Indoor, Outdoor and USB Modems that support various usage scenarios of subscribers. These modems

Page 11: IAD 2331 Fundamental of Network - 4G P1 WIMAX

are aesthetically pleasing and promise best-in-class performance through the combination of unique antenna design, advanced RF and MIMO technology. Additionally, customization was

included to re_ect P1’s branding.

In particular, our Indoor and USB Modems are designed to be truly plug and play, enabling subscribers to enjoy instant WiMAX access minus the complexity. This is achieved through automatic provisioning whereby subscribers’ login details and pro_les are preloaded into the modems.

As such, subscribers can immediately access WiMAX without having to handle authorization and authentication mechanisms on their own. Instead, these audits are performed securely behind the scene by the modems, creating a user-friendly environment and reducing reliance

on P1 Customer Support.

Unified Connection Manager to Represent a Consistent“P1 Experience”

” The wide array of end user devices (laptops, netbooks) and availability of different WiMAX chipsets can jeopardize P1’s ability to extend a consistent experience to subscribers. However, Green Packet’s unifieed connection manager supports multiple operating systems and is compatible with most major end-user devices and chipsets.

As such, P1 only needs to offer one connection manager to all subscribers. This simples customer service efforts as only one connection manager software needs to be supported.

World-class R&D

Besides our global presence that extends over 8 offices around the world, P1 was impressed with Green Packet’s world-class R&D efforts globally, in particular our Taiwan R&D Center.

Page 12: IAD 2331 Fundamental of Network - 4G P1 WIMAX

This center is dedicated to advancement in the WiMAX arena where a team of WiMAX specialists engage in consistent research and development activities to design and provide state-of-the-art WiMAX Modems with unrivaled performance and quality.

Gearing Towards the Next Phase

Green Packet’s relationship with P1 is built on a long-term strategic partnership. This is demonstrated via our commitment to continuously provide new and innovative solutions that supports P1’s vision.

Conclusion

In conclusion, 4G wimax is better in capacity, high speed than the previous network technology. The price for 4G is not cheaper than the other 2G and 3G wimax. However, it will be affordable cost. And also soon it will be used in single worldwide cellular network.

4G networks may eventually deliver on all the promises. At times, it seems that technological advances are being made on a daily basis. These advances will make highspeed data/voice-over-Internet-protocol (VoIP) networks a reality. In the meantime, it is important for industry to develop a strong 3G offering that is palatable for the general public. Equally as important, industry must ensure that expectations are realistic and that services meet and exceed those expectations. If all goes according to what the industry envisions, it may be sooner, rather than later that we will see wireless communications evolve. This evolution will give the general public as well as the public safety community amazing functionality from the convenience of a single handheld device.
