How guard spaces between users are realized in CDMA?
The guard space between a pair of users in CDMA is the orthogonality between their spreading codes.The lower the correlation between any pair of spreading codes is ,the better is the user separation.
What are the advantages of using CDMA for a cellular network?
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.
Disadvantages of code division multiple access?
main disadvantage of CDMA is Degradation of forformance if the number of user will be increases an RF channel.Bez in case of CDMA 10 users can acccess at the same time.

What is cell breathing in CDMA?
Breathing refers to the shrink in effective coverage area when a base station becomes overloaded with users and the subsequent recovery as users leave the area, as if the cell is "breathing".
Which is best CDMA or gsm?
CDMA, offers better data transfer
Are HTC phones CDMA?
Not all HTC phones are powered by CDMA.Some of CDMA phones are :HTC S720 (CDMA)HTC P4000 (CDMA)
How do you work CDMA technology?
CDMA means Code Division Multiple Access. it's a way to have many users sharing one media (air for example, since CDMA is used in GSM communication) Principle: each users uses a "spreading code" to cypher its data using usually a "XOR" algorithm with a code. "1" XOR "1100" => "0011" "0" XOR "1100" => "1100" In order to be able to recovers the original signal, all users have to use "orthogonal codes" (cross-corelation = 0), these codes are usually from a Walsh Matrix (see Wikipedia for more details) The receiver processes the corelation of the signal with all the sender's codes. The result which is the most relevant is said to be the original data. (see Wikipedia for more details on CDMA)
Is ATT CDMA?
no its HSDPA sprint or Verizon or both are cdma
What if operating frequency for CDMA network in yemen?
cdma gsm
What is CDMA repeater?
A CDMA repeater is a device that extends the signal range for cell phone providers that use the CDMA technology. CDMA (Code Division Multiple Access) is one of the technologies cell phone companies use for their phone service. More information on CDMA is available here: http://en.wikipedia.org/wiki/CDMA
Can you convert cdma sim to cdma?
