MOTOTRBO FREQUENTLY ASKED QUESTIONS
What is MOTOTRBO?
MOTOTRBO is the first digital two-way radio system from Motorola specifically designed to meet the requirements of organizations/industries outside the public safety sector mainstream that require a customizable business-critical communication solution using licensed radio spectrum. MOTOTRBO is a complete two-way radio system that includes portable and mobile radios, a repeater, accessories as well as powerful data applications, such as Text Messaging Services and Location Services.
Is MOTOTRBO a series of radios, or simply a single model of radio?
MOTOTRBO provides a complete dual mode (analog and digital) system including repeater, mobile and portable units, data applications, and accessories making it easy and affordable for large organizations/businesses to customize a MOTOTRBO solution to meet specific needs and migrate to digital at their own pace.
What does MOTOTRBO do?
MOTOTRBO combines exceptional two-way radio functionality with digital technology to deliver increased capability and spectral efficiency, integrated data applications and enhanced voice communications. In the ongoing effort to improve workforce productivity and operational effectiveness, organizations need to communicate with and provide information to employees anywhere on 24/7 basis-easily and cost effectively. This is especially important for organizations or enterprises whose workers are mobile—moving about a geographic area to accomplish their jobs.
Analog two-way radio technology is an effective, proven technology. Why switch to digital?
Offering advantages such as a lower total cost of ownership, customizable coverage and features, and a simple and reliable implementation makes analog two-way radios the clear choice for the vast majority of large organizations/enterprises with highly mobile workforces. However, this technology has reached the limits of its innovative life. Analog two-way radio has limited battery life, degrading voice quality near at the edge of coverage, and lacks integrated data applications. Additionally, as analog radio users reach their licensed spectrum capacity, crowding the interference occurs. These users can easily justify migrating to the digital technology of MOTOTRBO because they need clear, unbroken, reliable communications. A missed call, user error, garbled message or a dead battery can mean lowered productivity, wasted time and money, unsatisfied customers, interruptions to essential services, or lost business.
Motorola made an investment in the MOTOTRBO technology platform in order to bring integrated applications and advanced functionality to the large organization/enterprise two-way radio market. MOTOTRBO was developed to be offered at a competitive price-point compared to existing analog two-way radio solutions. As a result, we believe that MOTOTRBO provides such increased functionality and operational efficiency that end-users will want to move to digital platforms faster.
What standard is MOTOTRBO based on?
MOTOTRBO is designed to the globally-recognized European Telecommunications Standards Institute (ETSI) Digital Mobile Radio (DMR-Digital Mobile Radio) tier two standard for large organization/enterprise mobile radio. This provides an open platform that enables market acceptance and multi-vendor interoperability for voice and IP data and will assure competitive pricing while protecting customer investment.
Why TDMA and how does TDMA differ from FDMA?
Frequency-Division Multiple-Access (FDMA) splits the channel frequency itself into two smaller sub-channels that can carry separate calls side-by-side. By comparison, Time-Division Multiple-Access (TDMA) preserves the full channel width, but divides it into alternating time slots that can each carry an individual call. Motorola maintains that two-slot 12.5 kHz TDMA-based systems, providing 6.25 kHz equivalency, are the better choice for most large organization/enterprise radio users.
Wireless standards based on TDMA technology are already widely used around the world, and future requirements for even greater spectral efficiency also are expected to be based on TDMA.
TDMA technology for narrowband 12.5 KHz (6.25 equivalent-6.25e) organization/business radio users, provides advantages of feature flexibility, lower equipment costs, longer battery life, future-readiness, and the proven ability to increase spectral efficiency without risking increased congestion or interference.
Doesn't Motorola offer FDMA-based systems in addition to TDMA?
Motorola does offer FDMA-standards based two-way radio systems for large public safety and government communications networks that require dedicated channels.
Is MOTOTRBO compatible with P25 technology/systems?
No. The P25 protocol (TIA Project 25 standard) was adopted for public safety sector use and currently uses 12.5 KHz FDMA technology. MOTOTRBO supports the ETSI Digital Mobile Radio (DMR) standard for large organization/enterprise two-way radio customers and uses 12.5 KHz (6.25 equivalent-6.25e) TDMA technology.
