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. 2.2 Synchronisation 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 1s or better. 2.3 Power Supply AirUnity 545 is powered via an AC mains (line power) adapter which provides local DC power to the unit:

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 operators 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). 3.2 Protected 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). 3.3 Unused 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. 3.4 Tamper 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.

2002/95/EC (ROHS) compliant with ROHS6 (up to 2009) The WEEE symbol is present on the product label as per the requirements of European directive 2002/96/EC 6.6 Reliability and Maintenance The AirUnity 545 contains no user-serviceable parts. The following reliability data assumes worst case requirements. Overall reliability is improved when considering the dual transceivers as a redundancy factor (this consideration is not included in the quoted figures). Average Mean Time between Failures (MTBF) = 10 years.
