RIL to enter 4G services space Even as operators like Bharti Airtel, Tata Teleservices and Reliance Communications try to get their act together in 3G services, Mukesh Ambani-owned Reliance Industries Ltd has started trials on fourth-generation (4G) mobile technology and is getting ready to enter 4th generation telecom services. As per reports, RIL team at Navi Mumbai has started trials of 4G connection and got download speed of 80 Mbps and upload speed of 20 Mbps – that's much higher than current 3G connection of 3.1 Mbps or 7.2 Mbps. The 4G technology — which is due to be launched sometime next year – will be provided through RIL's telecom arm Reliance Infotel that won wireless internet spectrum auctioned recently. The 4G enables subscribers to watch high-definition video streaming while on the move and live mobile TV. Here the data delivery on mobile phones is even higher than 3G services, thus, you surf internet at lightning speeds. RIL at the moment is looking to finalise equipment as well handset orders. Sources tell NDTV that RIL is in talks with global technology major Qualcomm to get their LTE technology which will allow it to provide 4G services using the BWA band. What could prove challenging for many of the existing telcos is the fact that along with data, RIL is looking to provide voice service, and also making it literally into a full-fledged mobile service. :Sorprendido: And all of this will be at a much lower cost than 3G because the price of BWA spectrum is much lower than 3G spectrum.

Advantages of CDMA are: - It can accommodate more users per MHz of bandwidth than any other technology. - It has no built-in limit to the number of concurrent users. - CDMA is able to produce a reasonable call with lower signal (cell phone reception) levels. - Its variable rate voice coders reduce the rate being transmitted when speaker is not talking, which allows the channel to be packed more efficiently. - Has a well-defined path to higher data rates - Increased cellular communications security. - Extended reach - beneficial to rural users situated far from cells. Disadvantages of CDMA include: - Most technologies are patented and must be licensed from Qualcomm and due to its proprietary nature, all of CDMA's flaws are not known to the engineering community. - Breathing of base stations, where coverage area shrinks under load. As the number of subscribers using a particular site goes up, the range of that site goes down. - Manufacturers are often hesitant to release CDMA devices due to the smaller market, so features are sometimes late in coming to CDMA devices. Advantages of GSM: - Talktime is generally higher in GSM phones due to the pulse nature of transmission. - The availability of Subscriber Identity Modules allows users to switch networks and handsets at will. - GSM covers virtually all parts of the world so international roaming is not a problem. - GSM's maturity means engineers cut their teeth on the technology, creating an unconscious preference. Disadvantages of GSM: - In GSM multiple users share the same bandwidth - GSM has a fixed maximum cell site range of 35 km, which is imposed by technical limitations. - Pulse nature of TDMA transmission used in 2G interferes with some electronics, especially certain audio amplifiers. 3G uses W-CDMA now (Dont know if the same applies to CDMA) Which technology is the best for me? When asking yourself which technology to choose between CDMA vs. GSM, first ask yourself the following questions: 1. Is international roaming important to me? If you travel a lot to foreign countries, you might want to opt for a GSM phone for a better coverage. 2. Am I going to transfer a lot of data using the phone? If you intend to use the phone for mobile web browsing, watching television or downloading MP3s, you might be better off with a CDMA phone. Currently, it offers the best data transfer speed with its EVDO technology and is the clear winner for now. 3. Do I plan to change phone often? If you do, a GSM phone is best for you since you can swap the SIM card to a new device without having to re-enter your personal data.
