Efficient, high-compatibility, safe and reliable solution to keep smooth communications. With continuous expansion of city and rapid increase of urban population, traffic congestion becomes even more serious. Seven days a week, transportation system takes passengers to widely scattered stations along crisscross lines in safely and punctually. With in-depth understanding of customers’ challenges, Grandtime aims to build a professional transportation solution, which is capable of keeping smooth communications in any situation.

Challenge

The current system has a number of challenges. If a passenger wants to order a taxicab, the controller has to notify the taxi driver by calling their mobile phone. But if the taxi driver happens to be occupied, the controller has to keep calling other drivers one at a time until he finds a driver available to accept the job.

Solutions

PoC provides all the advantages of private two-way radio systems, but operates over existing cellular and WLAN networks to deliver wide area coverage. PoC supports one-to-one and one-to-many group calling.

When a job comes in, the controller initiates a group call over the dispatch system, which can be heard by all the drivers, to see who is available. In-built GPS technology enables the controller to see the location of each taxi through the dispatching system and quickly assign the job to the nearest available driver.

Benefits

The ability to make group calls cuts the cost of one-to-one calls using smartphones. As there is no need to invest in spectrum or infrastructure, this makes PoC a very cost effective solution.

GPS means central controllers now know the exact position and status of each taxi, making their job easier and the service more efficient.
