Enables UE signal identification during over the air analysis of LTE mobile devices in encrypted high-traffic wireless networks
An add-on to the WaveJudge 5000, Sanjole’s CipherJudge enables
• Real-time SIM key retrieval and parsing of ciphered traffic
• Identify and track UE’s within commercial LTE networks
• Test UE’s from lab to field environment
• Capture/decode/trigger off ciphered control messages such as handovers
LTE takes great measures to protect the mobile’s identity and the data packet payloads sent over the air. While important for mobile users, these privacy measures create challenges for testing a specific or groups of UEs.
Over the air analysis and monitoring is very effective for testing wireless devices and networks, saving hours if not days of time. Sanjole’s powerful air monitor WaveJudge 5000 test system provides real-time visibility into the interaction between protocol and physical layers in wireless transmissions, thus facilitating identification of root causes of problems. Thanks to the CipherJudge, the WaveJudge’s analytical power can now be extended with ease to test a UE operating in a live, high-traffic network. There is no longer a need to create special test setups, turn encryption off, or guess which messages are from the UE of interest.
The CipherJudge is a first to market, pocket-sized device that physically connects to a mobile of interest, and functions as an add-on to the WaveJudge 5000. By intercepting the messages between the ME (Mobile Equipment) and USIM (Universal Subscriber Identity Module), the CipherJudge allows the WaveJudge 5000 to uniquely identify a UE, and decode all messages between the lab- or
field-located UE and the eNodeB. In doing so, the CipherJudge enables engineers to benchmark network attach, debug handover issues and contribute to QoE analysis in deployed networks.
This ability to diagnose problems of a unique UE operating in a network serving hundreds of other users while encryption is enabled makes Sanjole’s CipherJudge a powerful tool in any engineer’s arsenal.

Sanjole’s CipherJudge was used by a leading US Tier 1 Operator to test and troubleshoot an LTE Smart Meter. The Operator’s engineers were able to test a new Smart Meter before deployment for issues that had the potential to bring down an LTE macrocell.FEBRUARY 2016: Visit Sanjole at the Mobile World Congress in Barcelona, February 22-25.
