Case Study Cellular Integration Resource Center Project Scope: QuadGen 24/7/365 center for all integration vendors to provide transport engineering, RAN integration, and troubleshooting support QuadGen Value: Tier 1 US operator asked QuadGen to manage all issues nationally due to our track record of rapid isolation and resolution of issues QuadGen processes and expertise expanded from one to six integration vendors via an operator branded center Overall average cycle time reduced from 2+ weeks to 4 days QuadGen increased first time success rate from 54% to 89% © 2017 quadgen wireless solutions, INC. 1 Proprietary and confidential

Case Study – Ethernet over Microwave (Backhaul) Within first month, QuadGen improved conversion success rate from sub 50% to over 90% Ethernet over Microwave Transport - Engineering & Integration Team Mobile Operator was experience high failure rate with EoMW conversions and turn up of new Ethernet hops Microwave Network contained single hop and multi-hop drain & target architecture Three installation companies were supporting the field operation which included provisioning the SIAD (Smart Integrated Access Device) with a pre-generated script and manually configuring the radio (Ericsson Mini Link, ALU 9500 MPR) Cutover activities were completed in maintenance window with limited ability to test during non-maintenance window Issues with the engineering for the SIAD would result in faulty configuration that Vendor had no domain knowledge or experience to troubleshoot Provisioning of the radio was a manual exercise – console into the radio and provision via GUI Created a solution for the carrier with the following service tasks: Validate Engineering document prior to generating SIAD configuration Identify and report back any failures with testing of OAM and bearer EVCs Pre-test EVCs (Ethernet Virtual Circuit) using drain SIAD during maintenance window 2 nights prior to cutover Host cutover bridge to provide subject matter expert Validate MSN assignments and provisioning, validate SIAD configuration and provide troubleshooting support as required. In some cases, take control of Field technician’s laptop to validate Microwave radio configuration © 2017 quadgen wireless solutions, INC. 2 Proprietary and confidential © 2017 quadgen wireless solutions, INC.
