Modernising On-Site Security Communications for a Global Power Technology Leader

25/08/2026
Introducing Our New Website

To maintain rigorous site safety and operational efficiency across critical infrastructure, a premier Global Power Technology Leader (existing customer) partnered with Eemits Communications to upgrade its aging security radio system. By replacing legacy analogue handsets and repeating equipment with cutting-edge Motorola MOTOTRBO digital solutions, the facility dramatically enhanced audio clarity, expanded site-wide coverage, and established a future-proof, resilient safety network.

Background & Background Challenges


Maintaining high-level security across expansive, high-value manufacturing and technology sites requires dependable, instantaneous communication. The site security team relied on legacy equipment—specifically ten ICOM analogue radio handsets connected via an older Hytera RD985 repeater infrastructure.

- Over time, the legacy setup faced typical analogue system bottlenecks:

- Degraded Audio Clarity: Analogue signals suffer from background noise and fading, particularly across dense structural walls and industrial machinery.

- Limited Signal Reach & Redundancy: Outdated repeater technology lacked modern battery backup features and digital error correction, posing risks during power outages or high-interference scenarios.

- Equipment Obsolescence: Maintaining aging analogue handsets was becoming increasingly inefficient compared to modern digital standards.

The Strategic Solution


Eemits Communications delivered a complete, turn-key upgrade transitioning the site’s security team from legacy analogue to a state-of-the-art MOTOTRBO digital radio ecosystem.

Key Solution Components:

- Handheld Digital Radios: Deployed high-performance Motorola MOTOTRBO R5 UHF Non-Keypad digital portable radios equipped with IMPRES Li-Ion IP67-rated batteries for extended, dust- and water-resistant shift operation.

- Digital Repeater Infrastructure: Installed a high-power Motorola SLR5500 Digital Repeater (400–470 MHz, 50W) housed in a robust, wall-mounted IP66 steel enclosure with dedicated duplexers and an offset dipole antenna array.

- Mobile & Fixed Stations: Integrated Motorola DM4600E UHF mobile units along with Alfatronix battery backup systems and folded dipole fixed antennas to ensure uninterrupted station control.

- Power Resilience & Backup: Incorporated SLA backup battery systems and dedicated cable assemblies ensuring seamless operation during grid power disruptions.

- Licensing & Compliance: Managed the Ofcom Technically Assigned License to ensure fully compliant, interference-free frequencies.

Business Results & Operational Value

The transition to Motorola’s MOTOTRBO digital standard provided immediate operational advantages for the security personnel on site:

Instantaneous & Clear Communication: Advanced noise-cancellation and digital signal processing deliver crisp audio regardless of background industrial noise.

Enhanced Worker Safety: Rugged IP67-rated R5 handsets provide total reliability in harsh environments, while multi-unit IMPRES smart chargers guarantee batteries are properly maintained and always ready for active shifts.

- Zero-Downtime Infrastructure: Integrated SLA battery backup systems ensure that even during critical power loss, site security comms remain fully operational.

- Turn-Key Deployment: Eemits Communications handled end-to-end delivery—from equipment provision and custom programming to Ofcom licensing and expert on-site engineering installation.
