    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.

    I would like to write something from the heart. Please bear with me if this looks uncomfortable. A real life example: During the terrorist attacks in Mumbai in 2008, majority of the attackers were carrying simple GSM phones with Sims that were obtained in India by giving fake identity documents etc. Immediately after the attacks started, Indian Security Agencies (Particularly RAW) was able to track down all this numbers and they were recording all the communications going on between the terrorists and their handlers. The handlers were instructing terrorists at different locations like Taj, Oberoi and Chhabad House minute by minute what to do with the help of the Live Coverage going on on all TV Channels. This continued till the entire operation was over and resulted in such a great loss of life and prolonging of the operation for nearly 2 and half days. The intelligence agencies were just recording the conversations which came out later in the media in all its gory details. Imagine if they would have instructed Indian Mobile Operators to switch off this numbers immediately on the 1st day itself instead of just recording. so much of precious human lives could have been saved. Alas this needs quick thinking and appropriate response which is sadly lacking in India. They had all the technology at their hand. Still did nothing and no out of the box thinking. Moral: With all the interception at your hand, it requires a solid pro active intelligence, monitoring and situation handling set up to effectively thwart threats to security which is still not operational in India and don't see it happening in the near future irrespective whether Blackberry grants access or not. Blackberry granting access means a lot to tickle our Patriotic feelings but on the ground it means big ZERO untill we have a very effective intelligence and situation handling apparatus in place which is not there right now and it just seems will not be there for years to come. Why i say so? If india would have valued the life of its citizens (More than 2,00,000 killed in last 20 years in terrorist, insurgency), it would be alive and kicking now. See America's example after 9/11 in revamping entire security structure with Homeland Security and preventing any significant attack after 9/11. We are not even able to punish the lone terrorist Ajmal Kasab even till now and spending Crores in keeping him safe! Unless and untill there is a total revamp of Intelligence structure, Effective Laws to deal with Terrorism, Speedy Justice, all this Blackberry interception things are symbolic gestures to keep us all deeply patriotic Indians in good humour. Symbolic only not Real!! And by the way why this Drama of discussing with Blackberry for such a long time to get access to the messanger system. If the authorities think earnestly that it is vital for India's security interests, then just ask them to grant access and if they are not giving, ban them. But no, this kind of thing will not happen here. Just this Nautanki will go on for some time. And when things will cool down and off the radar of media and general public, nothing substantial will happen.

    I beg to differ on some points, and am speaking from experience - Have experienced echoes with CDMA many times. Happens even with both parties are on CDMA! Voice distortion can also happen. Technically, voice clarity drops with increasing load in the cell. In Pune, voice clarity on Uninor, Idea and Docomo (with good phones!) are comparable to better than RCDMA at least (no experience with other CDMA networks). This depends on frequency. Here, I have found that Idea (900 Mhz) in-building penetration is generally quite comparable to RCDMA. Others operating on the 1800 Mhz band will obviously not be comparable. Can't argue with this. But GSM is also evolving...

    Voice Quality: Always very superior in CDMA. Echoes, Voice distortion, non existent in CDMA. Simple life example. Voice quality in GSM somewhat similar to Microphone Recodring in PC. In CDMA it is almost equivalent to 320 kbps MP3 audio quality. Coverage: CDMA better equipped to reach inside building areas than GSM Spectrum Efficienty: For a given spectrum say 5 Mhz, CDMA can accomodate more subscribers than GSM. Towers: CDMA can serve more subscribers in one tower than GSM. Also physical distance reach of the tower is better than GSM.
