Where does MOTOTRBO fit in Motorola’s portfolio of products?
Motorola has been leading the way in digital two-way radio communications for more than two decades, including the launches of ASTRO® 25 (compliant to TIA Project 25 standard) and Dimetra IP (compliant to ETSI TETRA standard), the industry’s first mission critical digital two-way radio systems for large public safety organizations. (Motorola’s first P25 system launched in 1996.) With the introduction of MOTOTRBO for the professional tier, Motorola will have the industry’s most comprehensive portfolio of digital radio solutions.
Is the radio intrinsically safe?
MOTOTRBO XPR Portable series radios have been certified by FM Approvals in accordance with Canada and U.S. Codes as intrinsically safe for use in Class I, II, III, Division 1, Groups C, D, E, F, G, when prop- erly equipped with a Motorola FM approved battery option (PMNN4069 IMPRES Li-ion, 1400 mAh, 7.2V, Submersible (IP57) Battery.
I see that the radio has “Basic Privacy,” what does that mean?
Basic Privacy utilizes a Motorola proprietary algorithm that works together with the provisioned Privacy Key to scramble and unscramble digital transmissions.
What is the lifespan for a MOTOTRBO system?
Because of the functionality and platform design, MOTOTRBO is positioned to be used in the professional radio user marketplace and meet customer needs for a long time. We expect MOTOTRBO to meet the average lifespan for existing professional two-way radio systems (approx. 5-7 years).
What standard is MOTOTRBO based on?
MOTOTRBO was designed to the globally-recognized European Telecommunications Standards Institute (ETSI) Digital Mobile Radio (DMR-Digital Mobile Radio) tier two standard for professional mobile radio. This provides an open platform that will enable 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 believes that two-slot 12.5 kHz TDMA-based systems, providing 6.25 kHz equivalency, are the better choice for most professional radio users. Wireless standards based on TDMA technology are already widely used around the world, and future requirements for even greater spectral efficiency are expected to be based on TDMA as well.
Are there any health issues with the TDMA technology?
Like all Motorola wireless products, our MOTOTRBO portable and mobile two-way radios are designed and tested to assure that they operate within reliable science-based standards and guidelines for safe exposure to radio waves. Numerous evaluations by scientific experts have reached the same conclusion—wireless communications products that operate within recognized guidelines pose no demonstrated health risk.
Is digital audio really better than analog audio?
MOTOTRBO provides better basic communications quality, including: • Improved audio quality at the edge of coverage. • Improved background noise suppression with digital voice processing automatically detecting. • Reducing background noise in the caller’s environment.
Who/what are MOTOTRBO’s biggest competitors?
Licensed analog two-way radios: While analog two-way radio offers certain advantages that make it the clear choice for some of the mobile professionals, such as the lowest total cost of ownership, customizable coverage and features and a simple and reliable implementation, it has reached the limits of its innovative life. • Analog two-way radio has limited battery life, degrading voice quality close at the edge of coverage and lacks integrated data applications. Additionally, more and more businesses are experiencing interference and crowding as they reach their licensed spectrum capacity. Push-to-talk over cellular: While this approach is easy to implement, it requires dependency on public net- work infrastructure with recurring service usage fees resulting in a high total cost of ownership (TCO) and uncertain coverage, reliability and feature availability.
I have heard some manufacturers talking about their 6.25 “true” FDMA solution, including benefits over TDMA alternatives. What’s the difference? Why is yours going to come out the winner?
While we can’t speak to other manufactuerer’s offering, Motorola believes that two-slot 12.5 kHz TDMA-based systems providing 6.25 kHz equivalency are the better choice for professional radio users. Wireless standards based on TDMA technology are already widely used around the world, and future requirements for even greater spectral efficiency are expected to be based on TDMA as well. Today and tomorrow, TDMA technology, for narrowband 12.5 KHz (6.25 equivalent-6.25e) professional 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. In addition to leveraging TDMA technology, MOTOTRBO offers integrated data applications and advanced features.
