How Authentication Center (AUC) works in GSM

When we talk about Mobile Business then its worst useful without authentication means to make Network as business all user required to be authenticate lets understand how authentication done in

Network Color Code NCC for GSM

NCC is a part of BSIC. MS uses it to distinguish adjacent BTS that belong to different GSM PLMN. NCC is composed of 3 bits, with the range of 0

State of RRC in LTE

RRC uses the following states: RRC_Idle: •The UE is not connected. There is no radio link. •The network knows that the UE is present on the network and is able

Dedicated Control Channel (DCCH) in GSM

SDCCH (Stand-alone Dedicated Control Channel) Uplink and Downlink. Used for call setup, authentication, ciphering location update and SMS. SACCH (Slow Associated Control Channel) Downlink and Uplink. Used to transfer signal

How Forward Link Channel Format in CDMA

The Base Station transmitter signal is, however, the composite of many channels (with a minimum of four). The Pilot channel is unmodulated (Walsh code 0); it consists of only the

BCH ,CBCH and CCCH works in GSM

Broadcast Channels (BCH) Frequency correction channel (FCCH) the “lighthouse” of a BTS Synchronization channel (SCH) PLMN/base identifier of a BTS plus synchronization information (frame number)  Broadcast control channel (BCCH) to

Codeword, layer, and precoding in LTE

Terms codeword, layer, and precoding have been taken to refer specifically to LTE signals and processing. The figure shows the processing steps to which they relate. The terms used in

Forward Traffic Channel of CDMA

Forward Traffic Channel is used to Transmit Data and Signaling Information. Symbol repetition makes symbol streams at different rates adapted to those at the rate of 19.2k. The original symbol

Downlink Power control in LTE

The eNodeB determines the downlink transmit energy per resource element (lte epre). Downlink cell-specific reference-signal (RS) lte epre is constant across the downlink system bandwidth and constant across all subframes until

LTE MIMO Types of Inputs and Outputs

LTE MIMO “input” and “output” are used for medium between transmitters and receivers, including both RF components – known as the “channel”. Thus, the base station with two transmitters provides

BCH,CCCH and DCCH Channel of GSM

BCH (Broadcast Channels) BCCH(Broadcast Control Channels) Downlink Only. Broadcast information of the serving cell (System Information). Transmitted on timeslot zero of BCCH carrier. Read only by idle mobile at least
