'''Code division multiple access''' ('''CDMA''') is a cellular frequency that, originally developed during World War II for military purposes, incorporates "spread spectrum" techniques. Unlike other cellular systems like [[GSM]] and [[TDMA]], every channel on the network uses the full available spectrum. This allows each user (identified by a unique [[pseudonoise code]] ([[PN]])) to communicate over several frequencies, as opposed to only one. CDMA is an improved version of TDMA (Time Division Multiple Access). TDMA uses a time-sharing protocol to provide three to four times more capacity than analog systems, just as a GSM.

'''Tool Name''' is a ...
  
[[Qualcomm]] developed the key advances that made CDMA suitable for [[cell phones|cellular phones]] and conducted an open demonstration in San Diego in November 1989.
 
  
The first CDMA network was launched commercially in 1995 as [[cdmaOne]] and provided approximately 10 times more capacity than analog networks. CDMA has become the fastest-growing of all wireless technologies, with over 100 million subscribers worldwide.

==File Systems Understood==
  
* Greater capacity. Provides 10-20 times the capacity of analog equipment and three times the capacity of other digital platforms.
+
==File Search Facilities==
* Excellent voice and call quality through the filtering out of background noise, cross-talk, and interference.
+
* Rapid deployment. CDMA systems can be expanded quickly and more cost effectively than most landline networks.
+
* Fewer dropped calls.
+
* Improved security and privacy because of CDMA's digitally encoded transmissions.
+
* Reduced background noise and interference by combining multiple signals which improves signal strength.

==Historical Reconstruction==
  
Most CDMA phones do not use [[SIM Cards]], so forensics can only be done on the phone itself, as all relevant data is stored directly on the phone. This information includes the [[phonebook]], [[call history]] log, [[SMS]] messages, and any calendar or to-do applications the phone might have.
+
Can it build timelines and search by creation date?
  
Due to the fact that the phone must be physically connected to a forensics workstation for data acquisition, it is important to be aware of the phone's battery state (a charging cable should be obtained to ensure constant power), and blocking the phone's signal. Also, the correct data cable must be obtained to connect the phone to the workstation ([[Susteen]] provides a kit that includes many cables for the most popular phones).

==Searching Abilities==
  
[[RUIM]] cards are the CDMA equivalent of a [[SIM Card]], and have been in use in china since 2002. The technology has spread to other countries throughout Asia, although are yet to be release in America.
