Upgrade from PMR446 to Professional Digital Radios
College Two-Way Radio Upgrade – From PMR446 to Professional Digital Radios
Tech College Radio System Upgrade
A local college had been using unbranded licence-free PMR446 radios to support day-to-day communication between staff. While these radios were inexpensive and easy to obtain, they began to create operational challenges across the campus.
Issues reported:
- Poor and inconsistent audio clarity
- Interference from other nearby PMR446 users
- Limited range across buildings
- Dropped communication in certain areas
- Lack of reliability during busy periods
With multiple departments relying on radios for co-ordination including estates, safeguarding, reception, and senior leadership clear communication was essential. The existing equipment was no longer meeting the college’s operational needs.
The Smye-Rumsby Solution
After carrying out a site review, Smye-Rumsby recommended upgrading to Hytera PD405 digital two-way radios.
Unlike basic licence-free radios, the PD405 provides consistent digital audio and improved signal stability. In addition, digital technology reduces interference from other users.
Smye-Rumsby recommended upgrading to Hytera PD405 digital two-way radios.
The PD405 offered:
- Professional digital audio clarity
- Improved signal consistency across campus
- Secure, interference-free communication
- Durable build quality for daily use
- Reliable battery performance throughout the working day
The radios were programmed and configured to suit the college’s operational structure, ensuring departments could communicate clearly without disruption.
The Outcome
Following the upgrade, staff immediately noticed the difference. Conversations were clearer, and communication became more dependable across the site.
As a result, the college now benefits from:
- Reliable campus-wide communication
- Fewer missed messages
- Faster response between departments
- Greater confidence in daily operations
This project demonstrates how moving from basic PMR446 radios to professional digital systems can significantly improve operational performance in educational environments.
The upgraded digital radio system is enhancing safety and security across the college, supporting staff during daily activities and events, and ensuring communication operates to professional digital standards.
