SPRINGFIELD — First, there were cordless phones and text messages. Then, internet access and video calls.

Now, wireless’s fifth generation will drive mobile phone speeds even faster and allow for advances in telemedicine and management of traffic signals, for example, according to the Federal Communications Commission.

But two lawmakers, Western Springs Democratic Sen. Suzy Glowiak Hilton and Elmhurst Republican Rep. Deanne Mazzochi, want to give residents, legislators and industry experts a chance to weigh in on the network upgrade.

“I think government really works best when the residents are engaged and active,” Glowiak Hilton said.

She asked five officials to speak to legislators on a Senate health committee Tuesday regarding concerns her constituents have about “potential effects” of 5G infrastructure. Their comments were decidedly mixed.

Those in favor of the wireless network upgrade said it would spur economic development and potentially save lives.

Bethanne Cooley, assistant vice president of a group representing the American wireless communications industry, said 3 million jobs will be created nationally — including 2,500 in Chicago and 1,800 in Aurora. She added first responders could reply to an emergency 60 seconds faster.
