Buses weave through the city's streets and alleys every day, facing traffic jams, route changes, and unexpected situations constantly. Drivers must focus on driving while staying in contact with the dispatch center. However, traditional walkie-talkies are limited by distance—once a bus leaves the main terminal, it "can't get through." Using a mobile phone, on the other hand, violates driving safety regulations and distracts the driver.
A few days ago, a fleet manager from a bus company approached us, saying that communication between drivers and dispatch had always been a challenge. They wanted a communication device that could support cross-regional calls and transmit on-site conditions back to the rear. We recommended the Hytera PNC380 PoC (Push-to-Talk over Cellular) radio.
All-Network PTT, No Dropped Connections Anywhere in the City
The PNC380 supports Mobile, Unicom, and Telecom 2G/3G/4G/WLAN networks. Leveraging the wide coverage of public networks, communication distance is unlimited. No matter how far the bus travels, calls can be made wherever there is a signal. The large PTT button enables one-touch individual and group instant calls, so the dispatch center can reach everyone with a single call.
5-Megapixel Camera + Video Backhaul, See the Scene in Real Time
Bus operations inevitably encounter disputes, accidents, and road anomalies. The PNC380 is equipped with a 5-megapixel HD rear camera. Drivers can take photos or record videos with one touch and transmit them in real time to the rear command and dispatch center via 4G. With the on-site footage visible, the rear team can make more accurate judgments and respond more efficiently.
Dual-Mic Noise Cancellation, Clear Audio Even in a Noisy Cabin
Bus engines are loud, and the cabin environment is noisy. The PNC380 adopts dual-microphone noise cancellation technology, which strongly suppresses ambient noise and accurately identifies the user's voice in noisy environments, ensuring no loss of call content.
4000mAh Large Battery, No Need to Charge All Day
Buses run from the first trip to the last, operating all day long. The PNC380 is equipped with a 4000mAh large-capacity lithium battery, providing over 24 hours of working time (5-5-90), meeting all-day operational needs. The Micro USB charging and data port allows for easy recharging on the bus or in the dispatch room.
Global Positioning, Dispatch Can See Vehicle Locations
The PNC380 supports coordinated positioning across multiple satellite navigation systems, including GPS/AGPS/BeiDou/GLONASS, with seamless indoor and outdoor transitions. The rear command center has full control of vehicle locations, enabling refined command and dispatch. In emergencies, the emergency call button provides one-touch SOS to ensure driver safety.
IP67 Protection, Withstands Daily Operations
The PNC380 meets the IP67 dust and water resistance rating and complies with MIL-STD-810G standards, having passed rigorous temperature, drop, shock, and vibration tests. It can handle the daily bumps and rainy-day operations of bus service with ease.
In bus dispatching, communication is efficiency and safety. With the PNC380, drivers and dispatch will never be "disconnected" again.
