In GSM networks, ASU is equal to theRSSI(received signal strength indicator, see TS 27.007). dBm = 2*ASU - 113, ASU in the range of 0..31 and 99 In UMTS networks, ASU is equal theRSCPlevel (received signal code power, see TS 25.125) dBm = ASU - 116, ASU in the range of -5...
The 802.11 standard does not define any relationship between RSSI value and power level in mW or dBm. Vendors and chipset makers provide their own accuracy, granularity, and range for the actual power (measured as mW or dBm) and their range of RSSI values (from 0 to RSSI_Max).[2] One...

Typical field values for RSRP range from -75 dBm close to site to -120 dBm at the edge of LTE coverage RSSI – Reference Signal Strength Indicator The RSSI is calculated as a linear average of the total power measured across OFDMA symbols which contain Reference Symbols transmitted from the f...
算法和与距离无关的(range—free)定位算法J。前者 需要测量节点之间的绝对距离或方位,并利用节点间 的实际距离来计算未知节点的位置。使用的定位算法 有三边测量、三角测量或最大似然估计等定位算法,常 用的测距技术有RSSI,TOA,TDOA和AOA等;后者则 不需要测量节点之间的距离和角度信息,算法根据网 ...
The reporting range of RSRQ is defined from -19.5 dB to -3 with 0.5 dB resolution RSRQ measurement report mapping (3GPP Reference: TS 36.133) Example Lets try to calculate RSRP, RSSI and RSRQ for one very simple case of one resource block with 12 sub carriers and 0.5 ms in time domain...

The path loss was obtained in the experimental setup and compared to Rician and Nakagami distribution models. However, the experiment was limited to the 30 GHz range, where the scope is narrowed down to the millimeter-wave (mmW) band. Meanwhile, Wang et al. [29] had achieved high accuracy...
