Sanjole introduces another exciting product called CipherJudge which allows identification of any UE on a commercialized LTE network. Identification of UE’s in the field can be quite difficult due to the lack of information available in a live network.  UE traffic is typically encrypted and the ID being used are temporary such as RNTI or GUTI.  The CipherJudge allows interception of critical ID and key related information from the USIM card which in turn is used by the WaveJudge 5000 powerful real time InteliJudge2 modules and provides quick and easy identification of targeted UE’s.  This allows analysis of one or more UE’s within any network, tracking all data and control plane messaging completely decrypted while charting the channel’s conditions.

“The ability to track any UE regardless of manufacturer within any LTE network, without having to rely on the vendor’s analytics, allow a completely independent view of the behavior during performance affecting times and is extremely beneficial” says Sanjole President, Joe Fala.

Sanjole began shipment on commercial orders for the WaveJudge 5000 with most systems being shipped to accommodate Carrier Aggregation testing of 2-3 carriers. This is significant due to the number of ports and frequencies required for these complex test setups which plays well into the form factor and price per port modularity of the WaveJudge 5000.

“While introduction of a new architecture is an exciting milestone for any company, moving product to commercialized production and shipment is one of the most important and satisfying stages for both the company and the client” says Sanjole VP Engineering Sandy Burusco.

Sanjole recently collaborated with Signals Research Group (SRG), a US-based research consultancy to monitor and analyze the performance of commercial LTE networks in the United States.  For the study, SRG leveraged the powerful capabilities of the WaveJudge 4900A LTE Analyzer and the IntelliJudge test platform to capture and analyze all protocol exchanges between the eNBs and all mobile devices within the coverage area.   The study included the four largest mobile operators in the United States and all of the major infrastructure suppliers with the testing taking place in San Francisco and Phoenix, Arizona, including the ASU campus in Tempe.

With the information provided by WaveJudge and IntelliJudge, SRG was able to identify measurable differences between networks / vendors, including differences in MIMO utilization, spectral efficiency, eNB scheduler behavior, and network loading.  The results of the study suggest that while LTE can be a highly-efficient air interface its performance can be meaningfully influenced by device and user behavior and an operator’s network strategy.  The 73-page report concluded by noting that operators should focus on in-building solutions, SON and continuous test and monitoring of its networks to maximize performance.

Sanjole enjoyed an overwhelming response to the introduction of its latest product offering, the WaveJudge 5000. With a record 80,000 attendees at Mobile World Congress in Barcelona, there were plenty of visitors to the witness the live demo in Sanjole’s booth.

“Each year we look towards introducing something very dynamic and this year was no exception. The ability to monitor a live LTE network, over the air, that is not controlled by Sanjole during the show, demonstrates the ability of our product to operate with any network under any condition. The system ran for over 4 days consecutively showing all aspects of the eNB LTE connections with all UE’s and their capabilities analyzed, displayed and recorded. This was done over a very chaotic wireless environment” says Sanjole VP John Loia.

Sanjole introduced the new WaveJudge 5000 at the Mobile World Congress in Barcelona. The WaveJudge 5000 combines greater capabilities and ease in testing with a scalable, customizable and cost-effective platform.

Sanjole is known for delivering solutions that collapse troubleshooting from days to minutes. Building on the powerful capabilities of the WaveJudge/IntelliJudge product line, the WaveJudge 5000 now also enables you to customize your troubleshooting platform to address demanding and evolving challenges with greater ease and efficiency.

In early January representatives from Sanjole visited Prague to test and troubleshoot throughput issues in the newly installed LTE network of a Mobile Network Operator.  Sanjole’s WaveJudge/IntelliJudge was first used in the Lab, under ideal conditions, to determine the maximum throughput and performance of a cabled/conducted LTE network, and then was used in the field to determine the reason for poor throughput and performance of the “Over The Air” LTE production network.

It was determined that the eNB was not scheduling all possible Resource Blocks to be used for user data, therefore reducing the maximum possible throughput.  Also, interference with a neighbor sector was measured, which also reduces the performance of the LTE network.

It is interesting to note that typical “Drive Tests” were done prior to the arrival of Sanjole, but it was not possible to find any of these issues during the Drive Tests.

Sanjole will be demonstrating the powerful testing capabilities of the WaveJudge product line at the Mobile World Congress in Barcelona, February 24 to 27.

The 2014 Mobile World Congress Conference will be focusing on the present state of the industry and debating future developments with in-depth analysis of the trends that are shaping it.

DECEMBER 2013: The Fribourg University of Applied Sciences in Switzerland uses the WaveJudge to educate their students on the principles of LTE.  Representatives from Sanjole were happy to provide hands-on faculty training in the beautiful city of Fribourg to assist in the development of the LTE curriculum.

OCTOBER 2013: Sanjole monitored a major Mobile Operator’s LTE network in Moscow to determine the cause of poor throughput performance. Some eNBs had high throughput performance (as expected), but other eNBs, from the same vendor, had poor throughput performance using the same UE. To troubleshoot and determine the root cause, Sanjole’s WaveJudge/IntelliJudge captured OTA signals from both eNBs to analyze the protocols and the Physical Layer RF characteristics.

AUGUST 2013, BOSTON: Sanjole held multiple training events on the east coast for clients in Massachusetts, Virginia, Washington D.C. and New Jersey during August.

Stops included visits to Qualcomm, Sprint, Alcatel Lucent, Mitre and Samsung. The tour included indoor and outdoor testing of LTE events.
