Hands-On Troubleshooting LTE with WireShark

Course Description

This extensive Hands-On course is aimed at Field Service technicians, Systems Engineers, Systems Specialists, Integrators, Developers, Designers, Customer Support and Systems Delivery Project Engineers who need to troubleshoot LTE service network Interfaces.

In particular the course will focus on the air interface, S1 interface carrying signals between MME, and eNodeB backhaul and the X1 Interface used to interconnect eNodeB devices.

It will teach the fundamentals of the supported protocols, how to filter traffic by protocol type, address and conversation and how to identify potential faults, failures and much more...

Students Will Learn

Use key functions of WireShark to capture and display protocol traffic
Measure delay, bandwidth, jitter and packet loss
Filter traffic by protocol type, address and service function
Identify potential protocol issues and problems
Monitor and extract calls and service exchanges
Analyze signaling exchanges
And more...
Hands-On Labs will include
Capture traffic over a network
Analyze Signaling protocols used
Troubleshoot call reachability
Record and playback exchanges to monitor multimedia service quality
Troubleshoot voice quality issues
Analyze call connections
And more...

Target Audience

Field Service technicians, Systems Engineers, Systems Specialists, Integrators, Developers, Designers, Customer Support and Systems Delivery Project Engineers.

Equipment Requirements
(This apply's to our hands-on courses only)

Attendees should supply their own laptop computer running Windows XP or Windows 7and have Administrator privileges to install the software. A working knowledge Windows will be assumed.

BTS always provides equipment to have a very successful Hands-On course. BTS also encourages all attendees to bring their own equipment to the course. This will provide attendees the opportunity to incorporate their own gear into the labs and gain valuable training using their specific equipment.
