There are still a tremendous amount of GSM and EDGE networks in use today - much of it Nortel as shown in this 2015 GSM drive test - and 4G Unwired has extensive worldwide experience with Nortel equipment. We have the skills and engineering tools to provide RF Frequency Planning services and spectrum carving for implementing newer RAN systems. In fact, with our partners, 4G Unwired has remotely retuned hundreds of GSM sites with great success for our clients. After the retune, we analyze your drive test data and system KPIs to ensure proper system performance. If you’re still operating a GSM network, give us a call to see how 4G Unwired can assist with your current build out plans.
