2.1.2 Digital Display (Touch Screen)
AirUnity 545 unit has 5.17” digital touch display to allow user to interact with the device and obtain
following information:
Power on
RN-UE status
eNB status
Number of end user(s) connected
Location (GPS)
Macro received signal level
Best Location Indicator / Installation Instructions
Unit Reset (hidden mechanism)
The user interface provides information to enable the end user to determine the optimal location for
AirUnity 545 operation.
2.1.3 SIM Card
AirUnity 545 provides an embedded SIM and a standard SIM card holder for the operator-provided
SIM, (installed during assembly). Security details are provisioned for the RN-UE in the same fashion
and generally on the same systems as for the Access UEs.
2.2Synchronisation
AS545 contains an integrated GPS receiver, which is used for location timing and synchronisation.
2.2.1 Synchronisation Compliance
AirUnity meets the synchronization requirements as they are defined in TS 36.104 and TS 36.133.
Inter eNodeB synchronization is supported to enable both 1PPS frame synchronization for TDD
interference avoidance and frequency synchronization for ICI avoidance.
2.2.2 Frequency Accuracy
For Frequency stability, the same source is used for RF frequency and data clock generation. The
modulated carrier frequency of the eNodeB has an accuracy of ±0.05ppm observed over a period of
one subframe (1ms).
2.2.3 Phase Accuracy
Phase accuracy, (required for TD-LTE interference coordination and for both TD-LTE and FDD-LTE
when considering MBSFN or ABS) is 1µs or better.
2.3Power Supply
AirUnity 545 is powered via an AC mains (line power) adapter which provides local DC power to the
unit:
AC/DC power convertor supports:

AC input voltage range US: 100-240V±10% at 50/60Hz
DC output voltage range: 10V –14V
DC cable length: 1.5M
2.4Internal Battery
AirUnity 545 has an internal battery to support installation. The battery only supplies around 60
minutes power to the backhaul device to allow identification of the best backhaul location.

3 Hardware Security
3.1Factory Generation of Device Key
Each device has a private key and associated certificate which is used to authenticate itself when
initiating communications. This private key is generated in the factory, and so is the corresponding
vendor certificate. This capability necessary in order to support large scale plug and play
deployments.
This device key is stored on the AirUnity 545 to allow it to authenticate to the network. If the private
key is compromised, then the device can be masqueraded by an attacker towards the operator’s core
network. Therefore, it is stored in an encrypted form.
In later releases a device-specific key will be introduced, this is a random number blown into on-SoC
eFuses during manufacture. This offers two points of additional protection namely: the key is not
discoverable by decompiling the code (an attacker will need to run code on the device in order to read
the eFuses); and the key can only be used to obtain the private key of a single device (because each
encryption key is unique).
3.2Protected SIMs
The design of the systems provides the option to solder an embedded SIM to the board instead of
using a removable SIM; this removes the temptation to steal the SIM. Additionally, the operator can
ensure that these SIMs can only be used with the Relay APN, which would make them unusable with
an ordinary mobile phone (because relay traffic uses nested GTP-U tunnels).
3.3Unused Port Security
Unused interfaces on the SoCs within AirUnity 545 are protected against attack by ensuring that the
corresponding pins are not connected to tracks on the circuit board. In addition to this hardware
protection the device drivers within the SoCs which service these ports are disabled.
3.4Tamper Detection
Simple tamper detection is provided in AirUnity 545 by the use of tamper-evident labels.
Hardware Ready for Secure Boot
The SoCs within the AirUnity 545 unit supports secure boot. This is to be enabled by a software
download in a later release. Enabling secure boot ensures that only trusted software will run on the
SoCs internal to AirUnity 545.
