What is Push-to-Talk over Cellular?

 PoC, or Push-to-talk over cellular, allows radio users to connect to others through data networks.  Not only that, but it means that users can get an instant response, providing others are connected through Wi-Fi, 3G or 4G.  Naturally, emerging 5G standards will appear very shortly. This means that, ultimately, you can push-to-talk with international users, not just those in close range.  This is a massive boost to anyone managing fleets and teams cross-continent!


Today, Push-to-Talk over Cellular uses the modern LTE cellular infrastructure of Mobile Network Operators to provide nationwide coverage with unlimited voice and video call groups



How Push to Talk over Cellular Works?


PoC devices connect to the cellular infrastructure of Mobile Network North America Operators like AT&T, T-Mobile, and Verizon, using a SIM card like those installed in cell phones. The result is a highly reliable network that requires no maintenance or operational expenses. An app on the PoC radio provides simple and convenient access to PoC services.

PoC network services are hosted in the cloud. The cloud services are located on privately hosted servers owned and operated by the PoC platform. Gateway routers provide connectivity between the LTE network and the PoC server. Dispatch Applications (used for group calling and GPS location tracking) and the Management Application (used to configure customer accounts) are connected to the PoC cloud server through the internet.

Introduction of Compactor Garbage Truck

  The   compactor garbage truck   is composed of a sealed garbage hopper, a hydraulic system and an operating system. The whole truck is a fully sealed type, and the sewage in the process of self-compression, self-dumping and compression all enters the sewage tank, which completely solves the problem of secondary pollution in the process of garbage transportation. It has the advantages of good performance, convenient operation and safety. Optional rear hanging bucket overturning mechanism or garbage bucket overturning mechanism. The outstanding features of the compactor garbage truck and other garbage trucks: 1. The garbage collection method is simple: change the dirty old appearance of garbage cans on the streets of the city, and prevent secondary pollution. 2. High compression ratio and large loading capacity: the maximum crushing pressure is 12 tons, and the loading capacity is equivalent to two and a half times that of the same ton of uncompressed waste. 3. Operation ...

How to Prevent Hydraulic Oil From Emulsifying On Concrete Mixer Truck?

The main cause of hydraulic oil emulsification on concrete mixer truck s is water in the hydraulic system, which is mixed with water after a long time. The removed hydraulic oil will form an emulsification of the hydraulic oil. We found that water enters the hydraulic system due to the following reasons: a. Working in a humid environment, the moisture in the air condenses due to the alternation of cold and heat, turning into water droplets and falling into the oil; b. The rainwater on the fuel tank seeps into the fuel tank due to the weak sealing of welding and connection parts; c.  Due to the damage of the pumping cylinder seal and the damage of the mixing motor, moisture is brought into the oil; d. Daily maintenance, cleaning, oil change, and maintenance process bring in moisture. To prevent the oil from emulsifying, we must first prevent moisture from entering the hydraulic system. When the car leaves the factory, the welding and connection parts must be manufactured in accord...

The Maintenance of LED Advertising Truck

 The generator is an important part of the LED advertising truck , and it is the power supply system of the whole truck. Except for the fixed-point parking of our advertising vehicles and plugging in an external power cord for playback, our generators are needed for power supply at other times. Therefore, in order to do a good job in advertising, we must pay special attention to the maintenance of our advertising truck generators. So how do we maintain our LED advertising truck generator? First of all, we have to regularly check the generator of our advertising truck, especially the inspection of the generator oil, and change the oil frequently. Take out the oil dipstick 20 minutes after it is not started or shut down, wipe the oil dipstick with a clean rag or paper towel, reinsert it into the oil hole for 10 seconds, and then take it out to ensure that the oil reaches the middle and upper parts of the lower and upper marks on the oil dipstick. Secondly, we need ...
