Network Radios (PoC) Frequently Asked Questions
Understanding the bridge between traditional radio and cellular technology can be tricky. This FAQ cuts through the marketing noise to give you the objective facts about Network Radios.
General Overview
What exactly is a Network Radio?
A Network Radio, also known as a PoC (Push-to-Talk over Cellular) or Android PTT radio, is a device that looks and feels like a "radio" or walkie-talkie. However, instead of using traditional radio frequencies (RF) to talk directly to another unit, it uses LTE cellular networks or Wi-Fi to transmit your voice as data.
Is a Network Radio a "real" radio?
It depends on your definition. If "radio" means using the device's own antenna to transmit to another antenna nearby (RF), then a pure PoC device is technically a specialized "cell phone" that can run one or more proprietary push to talk apps. In the hobbyist community, they are generally accepted as the logical evolution of wide-area communication.
What are the main advantages of using PoC?
The biggest "game changer" is range. While traditional handhelds are limited by line-of-sight unless there is a repeater in the mix) PoC radios allow you to talk across the country instantly. They provide the power of a million-dollar trunked radio system without the complex legalities or infrastructure costs.
Range and Connectivity
Do Network Radios work without cell towers or Wi-Fi?
No. A standard PoC radio requires an internet connection to function. If you are in a remote wilderness area with no cellular signal or Wi-Fi, the radio will not transmit.
What is a "Hybrid" or "2-in-1" radio?
These are specialized devices that contain both an LTE module and a traditional VHF/UHF radio.
• The Benefit: They can work anywhere. If you lose cell signal, you can still use the traditional RF side for local communication.
• The Limitation: When using the RF side, you are restricted to short, "line-of-sight" range (unless there is a repeater involved) rather than the nationwide reach of the cellular side.
Costs and Subscriptions
Is "Lifetime Free Service" a real thing?
Generally, no, not yet. While rare a few companies do offer it. However, in most cases these devices require a data plan and a server backend to route your voice. In some cases, the data plan is combined in the cost of the device, the industry standard is stil an all-in-one yearly fee (typically $20 to $50 USD) which covers both your data and server access, which used to be billed seporatley.
What is the difference between Corporate and Hobbyist platforms?
• Corporate (Global PTT): You act as the administrator. You pay for a fleet of radios and have total control over all channels and users.
• Hobbyist (TIDRADIO/ODMaster): Individual users buy their own radios and manage their own subscriptions via an app, joining or creating groups as they see fit.
What are managed providers?
A managed provider is a 3rd party seller that handles Everything for you from the sale of the radio, to managing your talk groups and the contacts that have in your device. Essentially, you must return to that business for everything from adding someone to your contacts list, adding or removing people or talk groups from your device, as well as even your device name changes. In summary, your device is managed and controlled by a 3rd party leaving you with minimal to no control most of the device.
Do I need a license to use a Network Radio?
No, not if the Poc device opperates stricktly within the celular LTE band.
• Cellular/PoC side: No license is required.
• RF side (on Hybrid models): If your device includes traditional VHF/UHF frequencies, you may still be required to hold a valid license (such as GMRS or Ham) to operate legally on those specific bands. Note on using hybrid VHF UHF POC radios. To be considered legal by the FCC's standards, even if you possess a valid GMRS license, the radio you operate on those frequencies should be type accepted or "approved" for the GMRS service, or other services in which you operate.
