Named the ď033 serviceĒ after the countryís emergency response telephone number, Tbilisi Medical Emergency Response Service Centre operates in and around the Georgian capital. The service provides 24/7 emergency medical care for Tbilisiís 1.3 million citizens from its 120 ambulances and intensive care vehicles.
Tbilisi Requires Advanced Digital Technology while Optimising its Investment in Analogue Radios Tbilisi Medical was upgrading its fl eet to provide new ambulances and equipment for its skilled emergency teams. As part of the modernisation programme, Tbilisi Medical wanted to replace its existing Motorola analogue 2 Way Radios with a digital system. Investing in a leading edge, future-proofed solution would help it save more lives by delivering uncompromising clarity for life-or-death critical communications to improve emergency response times. In addition to ensuring complete coverage across the city and its outskirts, Tbilisi Medical wanted to combine voice, text and position location services in a single device. Text messaging would allow paramedics and fi rst-aid teams to record and share written details of a patientís condition, prognosis and recommended treatment. GPS capability would give ambulance controllers a real-time status of each vehicleís current location and activity to minimise delays in despatching medical crews to the scene of an accident.
Also important was compatibility with the analogue radios used by doctors at the 10 hospitals in and around Tbilisi to where casualties are transported. The service needed a solution that was both affordable and could meet all its communications needs cost effectively. Tbilisi Medicalís long-term supplier and Motorola Licensed Partner recommended MOTOTRBO for its breadth of coverage, unrivalled audio clarity, cost-effective use of spectrum and depth of functionality.
Next-Generation Communications at an Affordable Price
The Motorola Authorised Partner set up MOTOTRBO base stations and DR3000 repeaters at Tbilisi Medicalís two control centres, installed a Motorola DM3601 enhanced display mobile radio in each of the 200 ambulances and built the GPS interfaces. Tbilisi Medical also purchased 60 DP3600 portable display and keypad radios for use by medical response teams working at the scene of an accident or in a patientís home.
The display panel allows users to create and receive text messages, identify callers, scan channels and monitor traffic. The DP3600ís navigation buttons allow rapid access to the radioís intuitive, menuís driven features and one-touch programmable options. A large, press to talk button ensures ease of use, even when wearing gloves
MOTOTRBOís support for digital TDMA technology splits a single channel into two virtual channels to provide twice the capacity of analogue. This gives Tbilisi Medical six channels for the cost of three and halves the number of base stations and repeaters needed. Two of the three channels are used to cover the east and west sides of the city, with each one providing voice and data over one virtual channel and GPS services over the other. The third channel is a dedicated emergency response covering the entire city. This has also been split to manage voice/data and GPS. The Motorola Authorised Partner managed user training for the new MOTOTRBO system. Ambulance crews were quick to learn how to operate the DP3600s and became competent users after just 12 minutes training. The eight control room dispatchers quickly adapted to the new system and continue to work closely with MZE to refine channel tuning and define and implement new functionality as they need it.
MOTOTRBOís backward-and forward-compatible platform means that SL4000 walkie talkies can be switched to analogue mode when ambulance crews need to liaise with hospital staff. Compatibility with analogue allows the migration to digital to be phased in over several years as part of the ongoing upgrade of its two-way radios.
MOTOTRBOís built-in location tracking functionality has been activated in the Motorola DM3601 mobile radios to give controllers a real-time display of fleet activity. Dispatchers can programme the system to receive the geographical coordinates of each vehicle at pre-programmed intervals, on demand or upon pressing the emergency button. Integrated position location is of critical importance to Tbilisi Medical Emergency Response Service Centre and optimises fleet management, scheduling, route planning and despatching. Working from accurate real-time information is critical for controllers at the point of decision and helps save time, money and lives. The robustness of the DP3600 hand portables, that are also dustproof and water resistant, enables them to withstand sustained rough use in all weather conditions. The long-life battery also helps improve efficiency by allowing emergency crews to use the radios for around 16 hours before recharging is needed.
MOTOTRBO Helps Save Time, Money and Lives MOTOTRBO has streamlined both routine and emergency call-outs for Tbilisi Medical. The improved speech clarity of digital over analogue means clearer communications, with messages getting through first time, even against the background of traffic in a noisy street. The wider range has eliminated communication black spots at the city limits while integrated GPS has optimised response times. Digital also enables users to make one-to-one as well as group calls, which means that medical crews only receive calls that are relevant to them. MOTOTRBOís emergency and man-down features ensure that all users are alerted instantly to a colleague in distress or requiring immediate assistance. MOTOTRBO is also highly affordable and meets all Tbilisi Medicalís communications needs at a fraction of the cost of alternative solutions.
Tbilisi Medical is the first emergency response service in the Commonwealth of Independent States (CIS) to purchase MOTOTRBO, but anticipates that others will follow its lead. MOTOTRBOís advanced digital platform breaks through to new levels of performance and allows organisations to meet their future needs flexibly and cost-effectively. Tbilisi Medical anticipates achieving a return on its investment in MOTOTRBO within 12 months.
