What are the difficulties involved in developing CDMA Network? I am a young networking student who lives in one of the countries in central Africa. I have started a research on CDMA and I wish to know more about CDMA Networking. I am counting on your input and assistance. Thank you.
Hi Maurice, the main advantage of a CDMA network is the higher data speeds and it exceeds the likes of GSM network in terms of bandwidth potential. It allows numerous signal to occupy a single transmission channel thus it makes full use of a specific bandwidth. It uses a much more higher and wider bandwidth, thus it increased the likelihood of jamming. Developed by the U.S. military, CDMA network have a much more secured way of connection against surveillance and the tampering. The CDMA transmission looks like noise, so it is difficult to to decrypt without the right coding patterns. CDMA have a much more  better spectrum resources being allocated, thus simultaneous conversations can be initiated through the same resources than GSM. The difficulties encountered over the CDMA network is that it cannot offer international roaming unlike the GSM network. Now the tools for establishing your standard CDMA network would be an antenna, a BTS, a MSC SGSN to do the usual traffic. A typical CDMA network consists of a Base Station like the transceivers and the antennas, a mobile switching controller, a mobile station as a means of communication output, an HLR or home location register used as a portal for your data of your members, an authentication center whose main function is to provide encryption parameters. One of the well known difficulties in CDMA is the near-far problem, wherein CDMA unlike TDMA channels, suffer from non-zero cross correlation between their codes. One of the fundamental challenges that arise in CDMA is how to increase the throughput while at the same time maintaining low energy usage for packet processing and communications
