2.5.2
Physical Ethernet Connectivity
The UE Relay exposes two Ethernet ports – one for local configuration/bring-up and the other for
connectivity to the small cell. Each interface is pre-allocated an IP address that can be reprogrammed
through the management interface.
2.6
UE Characteristics
The UE transmits at a maximum of 24dBm per 3GPP specifications, power controlled by the macro base
station.
UE chip and stack vendor
Qualcomm MDM 9225
UE Category
Cat-4
Tx Power
1 x 24dBm at the UE module
Bandwidth
5, 10, 15, 20MHz
MIMO
1 x 2
Full-Duplex Bands
B2 (PCS - North America)
B3 (1800MHz - International)
Each band represents a single
SKU. Multi-bands SKUs may be
available in the future.
UE IP addresses are automatically assigned by the network. The UE is using IPv4 addresses for routing.
2.6.1
Transmitter requirements
Max power, Min power, ACLR,
2.6.2
SIM Card
The UE Relay uses 2FF (standard) SIM Card that can be inserted without opening the enclosure, through
a slot with weather-protected door. It is recommended that the operator uses high-priority SIM card for
this application.
2.6.3
SIM Card PIN (CPIN)
Through the management system, a CPIN can be configured to offer further network protection in case
the SIM card is jeopardized.
2.6.4
APN Configuration
The UE Relay supports a single APN and can be configured via the GUI
2.6.5
RF Channel Configuration
Each UE Relay is designed to operate in a full-duplex mode in a single band (2, 3, 4, or 7). Within each
band, an administrator needs to configure the specific channel of operation in the form of:
-
EARFCN (Center Frequency)
2.6.6
Physical Cell ID (PCI)
The UE Relay allows an administrator to view the PCI the UE is connected to (if the UE is actually
connected to the network). The administrator may reconfigure a different PCI to which the UE should
connect. The administrator may also opt to “lock” the PCI to a specific desired physical cell.
