Analog Radio
A two-way radio that transmits voice as a continuous radio wave signal — the technology that defined professional radio communication for decades and remains in use in many enterprise environments today.
Channel
A pre-programmed radio frequency path within a two-way radio system that allows a designated group of users to communicate privately without interfering with other teams operating on the same radio network.
Digital Radio
A professional two-way radio that converts voice to digital data before transmission — delivering clearer audio, greater frequency efficiency, and integrated data features including GPS, text messaging, and optional encryption.
Dispatch Console
A centralized software or hardware system used by a dispatcher, operations center, or supervisor to monitor, manage, and communicate with multiple radio users and talk groups simultaneously — providing full visibility and control over a radio communication network.
DMR (Digital Mobile Radio)
An open digital radio standard that defines how professional two-way radios communicate — providing clearer audio, greater spectral efficiency, and integrated data features compared to analog radio systems.
FCC License
A federal authorization issued by the Federal Communications Commission (FCC) that grants an organization the right to operate professional two-way radios on specific licensed frequencies within a defined geographic area.
IMPRES Battery Technology
Motorola Solutions’ intelligent battery system that automatically communicates with compatible chargers to provide precise, adaptive charging cycles — maximizing battery capacity, extending battery lifespan, and providing accurate charge status information on compatible radios.
Intrinsically Safe Radio
A two-way radio certified to operate in environments containing flammable gases, vapors, or combustible dust without producing sparks or heat sufficient to cause ignition — required by OSHA and the National Electrical Code in classified hazardous locations.
License-Free Radio
A two-way radio that operates on shared, unlicensed frequency bands — requiring no FCC license but offering limited range, shared channels, and no interference protection from other users.
Licensed Radio
A professional two-way radio that operates on FCC-licensed frequencies exclusively assigned to a specific organization — providing interference protection, channel exclusivity, and the performance capabilities required for enterprise operations.
Motorola Ion
Motorola Solutions’ enterprise smart radio — a professional radio that runs Android applications, connects over Wi-Fi and LTE, and serves as a unified communication and operational management device for advanced enterprise deployments.
Motorola R2
Motorola Solutions’ entry-level professional two-way radio — a lightweight, easy-to-operate device designed for indoor commercial environments including hospitality, retail, and light facility operations.
Motorola R5
A mid-range professional two-way radio from Motorola Solutions offering digital capability, clear audio, and multi-channel operation — suited for hospitality, healthcare, and mid-sized enterprise deployments.
Motorola R7
Motorola Solutions’ flagship professional two-way radio — a rugged, IP67-rated digital radio built for the most demanding enterprise environments, including stadiums, large events, outdoor operations, and construction sites.
Motorola Solutions
A global technology company specializing in professional safety and security communications — and the manufacturer of the professional-grade radio and security systems SEI Wireless Solutions is authorized to sell, service, and support.
Motorola TLK
Motorola Solutions’ PTT over Cellular device — a push-to-talk radio that communicates over 4G LTE and Wi-Fi networks, enabling team communication across unlimited geographic distances without traditional radio frequency range limitations.
MOTOTRBO
Motorola Solutions’ professional digital two-way radio platform — combining DMR digital technology with enterprise-grade voice, data, GPS, and application capabilities in a single integrated system.
PTT over Cellular (PoC)
A push-to-talk communication technology that transmits voice over cellular data networks (4G LTE) rather than licensed radio frequencies — enabling instant radio-style communication across unlimited geographic distances wherever cellular coverage exists.
Push-to-Talk (PTT)
A communication method that allows a user to instantly transmit voice by pressing and holding a button, enabling one-to-one or one-to-many radio communication without dialing or waiting for a connection.
Radio Frequency (RF)
The portion of the electromagnetic spectrum used to transmit radio signals — and in the context of professional two-way radio, the specific licensed frequencies on which a radio system operates.
Repeater
A device that receives a two-way radio signal and retransmits it at higher power from an elevated position — such as a rooftop, tower, or mast — significantly extending the effective communication range of a radio system beyond what handheld units can achieve on their own.
Rugged Radio
A professional two-way radio engineered to survive demanding physical conditions — drops, dust, water, and extreme temperatures — meeting defined military or IP durability standards for outdoor and industrial environments.
Talk Group
A logical grouping of radio users within a digital two-way radio system who share a dedicated communication path — allowing private group communication across dozens of teams without requiring a separate licensed frequency for each.
Two-Way Radio
A professional-grade portable wireless device that both sends and receives voice transmissions over a designated radio frequency, enabling instant team communication without relying on cellular networks.
UHF (Ultra High Frequency)
A radio frequency band — with professional two-way radio systems typically operating in the 400 to 512 MHz range — well-suited for indoor environments, urban settings, and buildings with complex layouts where signal must penetrate walls and multiple floors.
VHF (Very High Frequency)
A radio frequency band ranging from 30 MHz to 300 MHz used in professional two-way radio communications — particularly effective for outdoor, open-terrain environments such as golf courses, construction sites, and outdoor event grounds.
WAVE PTX
Motorola Solutions’ cloud-based push-to-talk platform that enables voice communication across radio, cellular, and Wi-Fi networks — connecting traditional two-way radios with PTT-capable smartphones and devices on a single unified platform.
