What is C1 in GSM?

What is C1 in GSM?

GSM C1 formula and GSM C2 formula C1 is known as Path loss criterion parameter. It is used for cell selection and reselection. The path loss criterion is satisfied when C1 > 0. The C2 factor is used as reselection criterion. It is used for cell reselection only.

What is idle mode in telecom?

Whilst in GSM or UMTS idle mode, a mobile shall implement the cell selection and reselection procedures. The mobile has registered on the network, and is listening for paging messages. The mobile will be performing location area updates when necessary.

What is Rxlev in GSM?

RXLEV is a number from 0 to 63 that corresponds to a dBm value range. 0 represents the weakest signal and 63 the strongest. RSSI below -110 dBm are generally considered unreadable in GSM. RSSI in the area of -50 dBm are rarely seen and would indicate that the MS is right next to the BTS.

What is RX level in 2g?

RxLev represents the received signal level measured in dBm units. The range from -110 dBm to -48 dBm is mapped to codes from 0 to 63. The higher measured level, the higher code number.

What is UE camping?

“Camp on” is the UE state in which the UE stays on a cell and is ready to initiate a potential dedicated service or to receive an ongoing broadcast service. Camping on a cell by the UE in RRC_IDLE has several purposes: reception of system information for the camped cell (see Section 3.2);

What is RxQual in 2G?

RxQual is used in GSM and is a part of the Network Measurement Reports (NMR). This is an integer value which can be between 0 and 7 and reflects the quality of voice. 0 is the best quality, 7 is the worst. Each RxQual value corresponds to an estimated number of bit errors in a number of bursts.

What is RX level?

The Rx level is the power in dBm of the received signal. The server modems normally transmit at -13 dBm by default. Ideally, the Rx level should be in the range of -18 to -25 dBm. If the Rx level is under -25 dBm, the Signal-to-Noise Ratio (SNR) is likely to decrease, meaning that the speed also decreases.

What is RxLev in 2g?

RxLev represents the received signal level measured in dBm units. The range from -110 dBm to -48 dBm is mapped to codes from 0 to 63. The higher measured level, the higher code number. Values less than -110 dBm correspond to code 0 and values grater than -48 dBm correspond to code 63.

What is EC no in 3g?

Ec/No is the ratio between the received energy from the pilot signal CPICH per chip (Ec) to the noise density (No). In other way, we can tell, that it is the ratio of the received signal level (RSCP) to the sum of all levels of signals on the same frequency (RSSI).
