Signal Measurement Signal strength values are defined by a few different measurements which vary even more for different service modes. These measurements are as follows: 2014/08/12 - [Mobile/LTE and 5G] - [LTE] RSSI, RSRP, RSRQ, RSCP, SINR, EC/IO [LTE] RSSI, RSRP, RSRQ RSSI (Received Signal Strength Indicatior) - 단위 dBm (절대크기) - 단말에 수신되는 모든 Power의 총 크기 - 신호 세기에 인접한 채널의 간섭, 열 잡음 포함 - 2G (GSM)에서 ..

In an emergency situation, like Earthquake or Tsunami, degradation of quality of service may be experienced. Degradation in service availability and performance can be accepted in such situations, but mechanisms are desirable to minimize such degradation and maximize the efficiency of the remaining resources. When Domain Specific Access Control (DSAC) mechanism was introduced for UMTS, the origi..

RSSI (Received Signal Strength Indicatior) - 단위 dBm (절대크기) - 단말에 수신되는 모든 Power의 총 크기 - 신호 세기에 인접한 채널의 간섭, 열 잡음 포함 - 2G (GSM)에서 통신 감도의 척도가 되는 값이다. In telecommunications, Received Signal Strength Indicator (RSSI) is a measurement of the power present in a received radio signal. The RSSI of the modem is indicated by a negative dBm value. This value relates to the signal strength of the cellular sig..

Location Area Update : The location update procedure allows a mobile device to inform the cellular network, whenever it moves from one location area to the next. Mobiles are responsible for detecting location area codes. When a mobile finds that the location area code is different from its last update, it performs another update by sending to the network, a location update request, together with..
