LABEL DESCRIPTION
Cell ID This shows the cell ID, which is a unique number used to identify the Base Transceiver Station to
which the Zyxel Device is connecting.
The value depends on the Current Access Technology:
• For GPRS, it is the Cell Identity as specified in 3GPP-TS.25.331.
• For UMTS, it is the Cell Identity as defined in SIB3 3GPP-TS.25.331, 3GPP-TS.24.008.
• For LTE, it is the 28-bit binary number Cell Identity as specified in SIB1 in 3GPP-TS.36.331.
The value is '0' (zero) or 'N/A' if there is no network connection.
Physical Cell ID This shows the Physical Cell ID (PCI), which are queries and replies between the Zyxel Device and
the mobile network it is connecting to. The normal range is 1 to 504.
UL Bandwidth This shows the LTE channel bandwidth from device to base station. According to 3GPP
(MHz) specifications, the bandwidths defined by the standard are 1.4, 3, 5, 10, 15, and 20 MHz. The
wider the bandwidth the higher the throughput.
DL Bandwidth This shows the LTE channel bandwidth from base station to LTE device. According to 3GPP
(MHz) specifications, the bandwidths defined by the standard are 1.4, 3, 5, 10, 15, and 20 MHz. The
wider the bandwidth the higher the throughput.
RFCN This displays the Radio Frequency Channel Number of DL carrier frequency used by the mobile
network to which the Zyxel Device is connecting.
The value depends on the Current Access Technology:
• For GPRS, it is the ARFCN (Absolute Radio-Frequency Channel Number) as specified in 3GPP-
TS.45.005.
• For UMTS, it is the UARFCN (UTRA Absolute Radio-Frequency Channel Number) as specified in
3GPP-TS.25.101.
• For LTE, it is the EARFCN (E-UTRA Absolute Radio-Frequency Channel Number) as specified in
3GPP-TS.36.101.
The value is '0' (zero) or 'N/A' if there is no network connection.
RSRP This displays the Reference Signal Receive Power (RSRP), which is the average received power
of all Resource Element (RE) that carry cell-specific Reference Signals (RS) within the specified
bandwidth.
The received RSRP level of the connected E-UTRA cell, in dBm, is as specified in 3GPP-TS.36.214.
The reporting range is specified in 3GPP-TS.36.133.
An undetectable signal is indicated by the lower limit, example -140 dBm.
This parameter is for LTE only. The normal range is -30 to -140. The value is -140 if the Current
Access Technology is not LTE. The value is 'N/A' if there is no network connection.
RSRQ This displays the Reference Signal Receive Quality (RSRQ), which is the ratio of RSRP to the E-UTRA
carrier RSSI and indicates the quality of the received reference signal.
The received RSRQ level of the connected E-UTRA cell, in 0.1 dB, is as specified in 3GPP-TS.36.214.
An undetectable signal is indicated by the lower limit, example -240.
This parameter is for LTE only. The normal range is -30 to -240. The value is -240 if the Current
Access Technology is not LTE. The value is 'N/A' if there is no network connection.
RSCP This displays the Received Signal Code Power, which measures the power of channel used by
the Zyxel Device.
The received signal level, in dBm, is of the CPICH channel (Ref. 3GPP TS 25.133). An
undetectable signal is indicated by the lower limit, example -120 dBm.
This parameter is for UMTS only. The normal range is -30 to -120. The value is -120 if the Current
Access Technology is not UMTS. The value is 'N/A' if there is no network connection.
