✔ Performed testing and troubleshooting of Distributed antenna systems by using Spectral analyser, Test Phone and sweep tester. Facilitated the sweeping of lines in cases of damaged cables or suspicious antenna behaviour☞ Worked based on Tickets and Work orders received from National monitoring centre and from customers who submitted their phone or e-mail complains to the NOC. ☞ Performed final punch walks, and acceptance of new DAS systems built as upgrade to support LTE technology in existing sites and new DAS systems. ☞ Executed yearly site audits for every single site, including antennas, lines (Fiber and coaxial), and remote equipment.☞ Developed parts lists and placed orders for test systems and created documentation package including test procedures and instruction manuals. Interfaced with regional engineering teams, field operations, third party DAS providers, development teams, and venue owners. Collected data for post deployment acceptance testing to ensure requirements were met.☞ Made extensive use of a variety of measurements to confirm system designs including test equipment, power density and power meter, spectrum analyzer, pilot scanner, fiber testing, reporting and troubleshooting. Coordinated and performed ongoing system testing, test analysis, test reports and recommendation for changes and upgrades.
