CDMA Turn On Process
System Access: When the mobile first turns on, it must find the best base station. This is similar to analog where the phone scans all the control channels and selects…

CDMA Soft Handoff Completion
If it is available, the second cell site returns the Walsh Code that will be assigned for the soft handoff. At this point, the original base station orders the soft…
What is inside SYNC Channel Message in CDMA
The sync channel messages include the CDMA protocol revision supported by the cell site, the minimum protocol revision supported by a CDMA mobile in order to work with the cell…
CDMA Soft Handoff Initiation
Once a call is established, the mobile is constantly searching for other possible cell sites that might be good candidate for soft handoffs. Most of the search time is limited…
CDMA Call Completion
After each access attempt, the mobile listens to the Paging Channel for a response from the base station. If the base station detects the access probe from the mobile, it…
How CDMA Call Initiation
The user then decides to make a call. The number is keyed in and the send key is hit. This initiates an Access Probe. The mobile uses a special code…
What is inside PAGING Channel Message in CDMA
The paging channel is the heart of a CDMA base station. All of the parameters and signaling necessary for the proper operation of a CDMA cell site are handled by…
What is Pseudo-Noise Code and M-Sequence in CDMA
Here I write about Pseudo-Noise Code and what its use Pseudo-Noise Code its two type and Pseudo-Noise Short code is identification for each BTS and Pseudo-Noise Long Code is Identification…
Google Quarterly Revenues jumped by nearly a third to US$14 billion
Google has reported that its first-quarter revenues jumped by nearly a third to US$14 billion, while profits rose to US$3.35 billion, compared to US$2.89 billion a year ago. Google said…
CDMA Handoff Defination,Types and Capacity
Handoffs The TIA/EIA Interim Standard, Mobile Station – Base Station Compatibility Standard of Dual- Mode Wideband Spread Spectrum Cellular System (TIA/EIA/IS-95), states that a CDMA base station shall support three…
Radio Protocol Architecture in LTE
The EUTRAN radio protocol model specifies the protocols terminated between UE and eNB. The protocol stack follows the standard guidelines for radio protocol architectures (ITU-R M1035) and is thus quite…
