Huawei's Telecom Technologies for India
At Huawei’s India IP Time 2009 event held recently, Huawei showcased and demonstrated various telecommunication products for the Indian market. The key technologies showcased at this event were an end-to-end network that included applications, application services delivery etc, which enable telecom operators to build applications on top of Huawei s RMS (Resource Management System).
Huawei also showcased their routers and router networks through which services can be provided via wired or wireless connections. As India enters the 3G era, it will enable operators to migrate smoothly from 2G to 3G networks.
Some of the India-specific solutions showcased by Huawei were IMS (Integrated Management Platform), which enable operators to offer new services and ICT (Integrated Communication Platform), which helps enterprises unify communications to improve productivity. On the ‘green IT’ front, Huawei has further reduced the size of their routers and reduced the power requirements too. Huawei unveiled Multi-Service Transport Platform (MSTP) — an optical, microwave and electrical communication platform that can transmit, aggregate and group data on TDM and IP. This platform allows the operators to select the medium of transmission they prefer.
For instance, places where there are a substantial number of subscribers, using Optical Fibre Cables (OFC) would be an ideal choice. Microwave, on the other hand, is best suited for remote places.
One of the key issues of communication in India is reliability, especially during network breakdown due to cable damage or failure. In such a scenario, Huawei s MSTP, which works in a ‘mesh’ network, is intelligent enough to figure out which path is broken and can automatically switch data traffic on to a different path. The system is able to do this in just under 50 milliseconds. According to Huawei, a user watching a streaming video or on a voice call, will not see a lag or experience call drop.
At the event Huawei also showcased their 40G network services. As bandwidth usage in a network increases, operators have two choices — either add more links or provide more capacity on each link. Adding more links entails additional investments and providing more capacity involves intelligent engineering. Huawei s 40G technology subscribes to the latter option. It does so by increasing the wavelength of signals passing through each fiber to 40G, effectively increasing the data carrying capacity of each fibre by four times.
Another benefit of using the 40G technology is that data can be transmitted over a distance of 1,500 km without any signal regenerators. Telecom operators using Huawei s 40G network will be able to upgrade to the 100G network with a little modification to their existing equipment.
