Founders of Modern Mobile Handoff: How Two Researchers Built the Backbone of 4G/LTE Connectivity

Dr. Abdelsalam “Sumi” Helal and Dr. Edwin A. Hernandez, developed patented foundational 4G/LTE handoff technology years before the smartphone revolution

GAINSEVILLE, FL, UNITED STATES, December 31, 2025 /EINPresswire.com/ -- If you have ever taken a phone call on a train, streamed video while riding in a car, or used your phone in motion without interruption, you’ve relied on the patented wireless mobility technology created decades ago, long before smartphones or mobile streaming existed.

That technology was developed by Dr. Abdelsalam “Sumi” Helal and Dr. Edwin A. Hernandez, the inventors behind patented wireless handoff innovations that allow cellular networks to anticipate where a device is moving and prepare the next connection in advance. The result is seamless transitions between cell towers, an invisible system that supports modern 4G LTE and 5G connectivity.

“When my mom watches Facebook on her phone while I’m driving, she doesn’t notice anything happening,” Hernandez said. “She’s switching between thousands of network cells, but it feels like one continuous connection. That’s what our technology enables.”

The origins of that innovation trace back to 1999 at the University of Florida, where Helal taught one of the nation’s earliest wireless classrooms. As part of the course, he challenged students to consider how reliable internet connectivity might work on a high-speed bullet train, an idea that seemed impractical at the time.

“Back then, you could barely stay connected driving across town,” Helal said. “The idea of streaming video while moving at high speed felt like science fiction.”

One student, Hernandez, a Honduran entrepreneur who had come to the United States after Hurricane Mitch destroyed his internet service provider business, took the assignment far beyond its scope. What began as a class project became his doctoral research and ultimately a portfolio of patents that now support modern cellular networks worldwide.

Solving seamless mobility was only part of the challenge. At the time, testing wireless performance required loading vehicles with phones and driving around cities, an approach later popularized by the “Can you hear me now?” era of wireless advertising. Helal and Hernandez instead developed Ramon, a hardware-based system capable of simulating high-speed mobility in a laboratory environment, laying groundwork for testing principles later adopted by the mobile industry.

Today, the technology is widely licensed and recognized across the wireless industry. Helal and Hernandez later founded Mobility Workx to steward and license their intellectual property and to continue engaging with industry leaders on the future of wireless infrastructure. As connectivity demands grow across autonomous transportation, smart cities, artificial intelligence systems, and massive device ecosystems, the need for seamless mobility continues to intensify.
