Mod-G Systems was founded to positively impact the Wireless Telecommunications Industry through the innovation of new products and techniques to Modularize site design and construction.

Our Products and related Services cater to many types of wireless infrastructure projects including New Site Build, Build to Suit, Tower Foundation Modification, Drop and Swap, Site Relocations, Temporary Sites, Special Events, and Disaster Recovery.

Our mission is to provide an option for the deployment of communication site infrastructure in a Modular manner.  We believe doing so can better utilize network development capital, allowing for the expansion of 5G services and overall broadband service at the speed and scale required to connect people to public safety, education, commerce, voice and internet services.

Using our extensive Wireless Site Development experience , we support our Clients’ overall network expansion and upgrade goals in a Modular fashion.  We collaborate with all levels and types of industry personnel to solve issues for our projects and the greater industry.

Residential, Commercial and now Wireless design and construction practices are shifting more frequently to Modular options due to a lack of consistent construction and material resources, and the factory quality, flexibility, certainty, and readiness that  Modular can provide.

As Principal of Mod-G, I pledge to make you a believer in our Modular Generation revolution.  I know, it sounds too good to be true.  However, I’m confident that if Mod-G can meet your project’s design requirements, you’ll also become a believer in the benefits, solutions, and opportunities our Modular Approach promotes.

Build Modular, Build with Mod-G.
