Further elaboration on certain major technology our Group utilised are as follows:-
3G is an evolution of the current systems already in place by telecommunication companies around the world and is capable of delivering a multitude of multimedia services. 3G is a broadband, packet-based transmission for text, digitised voice, video and multimedia at data rates from 384 Kbps and up to 2 Mbps based on the GSM communication standard of UMTS.
A comparison of these services is simplified in the figure below:-
There are basically many advantages of deploying 3G over the conventional 2G and 2.5G services. Firstly, the radio multiplexing system, WCDMA, makes more efficient use of spectrum. Secondly, a family of modulation schemes have been developed which allow single user channels of different data rates up to 2 Mbps. Thirdly, the difficulties of managing a multitude of disparate services at different data rates are very much simplified in a WCDMA system.
Of these advantages, improved capacity and data speed are 2 essential benefits of wideband technology such as 3G as it exploits multi-path propagation more efficiently than GSM, particularly in indoor environments. As with all new technologies, it will take time for 3G networks to prevail. Meanwhile 2G, 2.5G, 2.75G and 3G networks will most probably coexist in the same market for quite some time.
A summary of advantages and key attributes of 3G over the conventional 2G are diagrammatically illustrated below:-
Since the inception of cellular telecommunication networks in the early 1980s, cellular technology has evolved rapidly. First generation analogue wireless systems were replaced by 2G digital technologies in the 1990s that delivered significant improvements in capacity, voice quality and spectral efficiency. Most importantly, 2G technologies laid the foundation for the value-added services, including data, which will continue to be enhanced in the future. The latest 3G technology promises further improved network capacity, high-speed packet data, simultaneous data and voice and real-time multi-media services. Benefits of 3G essentially provides end-users with a full suite of innovative services such as mobile access to Internet, videoconferencing, and sending and receiving high quality images.
Typically, there are 3 specific global wireless phone standards for the 3G system:-
- WCDMA (Wideband CDMA);
- CDMA 2000; and
- Time Division-Synchronous CDMA (“TD-SCDMA”).
The WCDMA standard is based on UMTS recognised by the International Telecommunication Union. The CDMA 2000 standard was developed in the USA, and the TD-SCDMA was developed in China.
The WCDMA system is a hybrid system incorporating TDMA and CDMA technologies using specially designed spreading codes to allow optimum flexibility and eliminate interference between users operating at different data rates on the same RF carrier. Multiple services, from voice to a combination of data such as fax and e-mail, as well as video, can simultaneously be provided on each 3G terminal connection. Each service can be optimised at the required data rate and for the specific quality of service required by text, video or voice.
In Malaysia, 3G services are available through WCDMA technology, which offers much higher data speeds to cellular and portable wireless devices than commonly offered by 2G or 2.5G. It supports cellular/portable voice, images, data and video communications at up to 2 Mbps.
Our Group obtained the technical expertise and know-how to implement 3G network through technology transfer from our collaboration and projects with our technology partners. Our expertise was garnered through years of working relationship and project management for telecommunication network, system architecture and design. Our expertise in NGTS is derived from the domain knowledge of our Group acquired through our technology partners as diagrammatically illustrated below:-
Our Group believes that our primary core competency is the ability to create new innovative solutions. Considering the fast changing new technologies that have evolved over the last few years and recognising the huge potential in telecommunication solution, our Group has successfully implemented 3G network locally for Telekom Malaysia.
Our Group’s knowledge of the local business conditions, reputation and established relationships with technology partners has given our Group an edge over our competitors. As such, our Group intends to quickly capture emerging niche market in the areas of telecommunication solution through the value-added extension of our core competencies, from telecommunication system architecture and design to 3G related solutions and services.
Our Group is providing broadband solution using NGN technology to Telekom Malaysia. NGN seamlessly blends PSTN and the PSDN, creating a single multi-service network. This next generation architecture pushes central-office functionality to the edge of the network. The result is a distributed network infrastructure that leverages new, open technologies to reduce the cost of market entry dramatically, increase flexibility and accommodate both circuit-switched voice and packet-switched data.
Next generation switches are the most flexible platforms available. Combining extreme scalability, an open service creation environment, remote management and diagnostics and the highest availability, next generation switches provide a migration path from today's switching architecture to a more cost-effective, efficient, next generation network architecture.
MSAN is an integrated platform for the provision of voice, data (narrow band) services as well as broadband services including IP and Asynchronous Transfer Mode. It is capable of supporting thousands of broadband users on a single Asynchronous Transfer Mode/Ethernet network interface.
MSAN supports next generation voice networks with interfaces to both TDM-based voice and Voice-over-IP/Softswitch architectures. This makes it an ideal solution for migrating to VoIP via a simple software upgrade with no additional hardware required. Our Group works closely with our technology partner on the implementation of MSAN projects.
DSLAM delivers exceptionally high-speed data transmission over existing copper telephone lines. A DSLAM separates the voice-frequency signals from the high-speed data traffic and controls and routes xDSL traffic between the subscriber's end-user equipment (router, modem, or network interface card) and the network service provider's network.
DSL technology is a platform for delivering broadband services to homes and small businesses. DSL can support a wide variety of high-bandwidth applications, such as high-speed Internet access, telecommuting, virtual private networking and streaming multimedia content. In the past, these services were either not possible to support or were ineffectively supported by conventional, dial-up, data-delivery technologies. DSL can transmit up to 100 Mbps currently to a subscriber, which is enough to provide Internet access, video on demand, and LAN access. This increases the existing access capacity by more than 50 fold, enabling the transformation of the existing public network. This network is no longer limited to voice, text and low-resolution graphics and it supports multimedia (including full-motion video) around the globe.
