Signal Coverage - drive through a long tunnel or ride a lift and your phone's dead. Other ones could be - No Data Packet Access in simple CDMA (e.g. you can browse the net' on your phone) Less Users - More Cells needed to service people. Remember the old problem of sending an SMS and it taking ages for it to go through? Happy to help 'Matt

Qualcomm, Boost Mobile, MetroPCS, Leap Wireless International Inc., Net 10, Sprint, Verizon, Cricket, and Alltel use CDMA technology.
CDMA technology uses spread spectrum concept thereby giving users unique code to de-spread the information being sent to them. so CDMA is secure and occupies a large bandwidth of information compared to GSM technology.
no mts is 1600mhz cdma but nokia 2112 has only 800mhz cdma technology you can check also
A CDMA repeater is a device that extends the signal range for cell phone providers that use the CDMA technology.

Alltel phones run on CDMA technology, and there currently is no unlocking solution for CDMA phones.
Hand off
At this point in technology. It would be Bulkier Cabling. Which means worse Air Flow and hotter temperatures. Slower Speeds
One big limitation is the lack of enabling technology
Metropcs phones run on CDMA technology and right now, there is no unlocking solution for CDMA-based phones, only for GSM phones.
