Nationwide Push to Talk
Powerful PoC Communication Solutions
Expand your operational reach instantly with advanced Nationwide Push to Talk (PTT) solutions from Teltra. Moving beyond the geographic limits of traditional local repeaters and antenna towers, our modern Push-to-Talk over Cellular (PoC) technology leverages existing 4G, 5G, LTE, and Wi-Fi networks to connect your mobile workforce across the country with the touch of a single button.
Drawing on our extensive background in enterprise two-way radio system integration, we seamlessly bridge the gap between your physical Land Mobile Radio (LMR) footprint and nationwide broadband devices. Whether you are managing cross-country logistics fleets, deploying security teams across state lines, or connecting remote job sites back to your high-capacity trunking radio networks, we deliver crystal-clear, low-latency audio, real-time GPS tracking, and secure communication wherever cellular coverage exists.
CONNECT YOUR ENTIRE FLEET WITH CUSTOM POC SOLUTIONS!
The Core of Push-to-Talk over Cellular (PoC)
Historically, expanding a private radio network to cover an entire state or country required millions of dollars in infrastructure, towering antenna arrays, and complex FCC frequency licenses. Modern PoC communication solutions eliminate this capital expenditure by utilizing the massive, established data networks of major cellular carriers while retaining the instant, one-to-many communication style of a traditional two-way radio.
To provide a true enterprise-grade network, your Nationwide Push to Talk system must deliver on three critical fronts:
-
Zero Infrastructure Constraints: Because voice data is transmitted securely over national broadband and Wi-Fi networks, your communication range is virtually infinite. If your device has a cellular or Wi-Fi signal, you have instant radio coverage.
-
Seamless LMR Interoperability: Modern enterprises rarely abandon their physical radios entirely. Advanced PoC platforms utilize Radio over IP (RoIP) gateways to bridge your new nationwide cellular radios directly into your existing analog or digital radio channels.
-
Consolidated Smart Hardware: Commercial PoC devices merge the rugged durability and tactile PTT buttons of industrial radios with the smart capabilities of Android-based mobile computers.
This allows workers to carry one device for voice, video, inventory scanning, and data entry.
5 Engineering Standards for Nationwide Push to Talk
When architecting a broadband communication network for your fleet, Teltra focuses on strict metrics that guarantee security, visibility, and compliance. We prioritize the following five technical standards for all PoC deployments:
| Engineering Standard | Operational Benefit | Ideal PoC Application |
| 1. 4G/LTE & Wi-Fi Auto-Switching | Seamlessly transitions between cellular data and facility Wi-Fi to eliminate dead zones. | Logistics hubs, massive warehouses, and deep subterranean basements. |
| 2. Real-Time GPS Telematics | Allows dispatchers to track exact coordinates, route histories, and vehicle speeds. | Courier fleets, cross-country trucking, and regional public transit. |
| 3. DOT-Compliant Operation | Utilizes tactile buttons and foot-switches to ensure legal, hands-free driving. | Commercial motor vehicles (CMVs) and heavy equipment transport. |
| 4. Cloud-Based Web Dispatch | Centralizes command, allowing a single PC dispatcher to coordinate teams globally. | Corporate security operations, taxi dispatch, and fleet management. |
| 5. AES-256 Digital Encryption | Secures highly sensitive voice and video traffic across public cellular networks. | Executive VIP protection, hospital transport, and armored logistics. |
Custom PoC Infrastructure Engineered by Teltra
Teltra provides comprehensive engineering support from the initial software configuration to the final hardware deployment. We evaluate your fleet size, geographic challenges, and existing communication infrastructure to design a unified nationwide backbone.
Bridging the Gap: LMR to Broadband Integration
If your factory floor operates on a traditional digital radio system, but your delivery drivers travel hundreds of miles away, Teltra engineers bridge the gap. By installing specialized Radio over IP (RoIP) gateways, we link your local radio frequencies directly into our cloud-based PoC servers. When a supervisor on the factory floor speaks into their standard digital radio, the audio is instantly broadcasted over the cellular network to your drivers on the road.
Rugged and Scalable Device Selection
Unlike consumer walkie-talkie apps installed on fragile personal smartphones, Teltra deploys purpose-built, commercial-grade hardware. We equip your teams with ultra-rugged devices—from the pocket-sized Hytera PNC360S for hospitality staff to the advanced Hytera PNC560 5G smart computer for logistics and inventory management. For vehicle fleets, we install heavy-duty, dash-mounted PoC mobile radios that withstand constant road vibration.
Advanced Fleet Tracking and Dispatch Consoles
A primary advantage of Push-to-Talk over Cellular is the rich data it provides. We configure powerful desktop dispatch software for your command center. This allows your dispatchers to view live GPS maps of all active radios, record and playback voice transmissions, geofence specific delivery zones, and instantly push multimedia files or text messages to specific teams in the field.
Nationwide Push to Talk: Frequently Asked Questions
What is Push-to-Talk over Cellular (PoC)?
Push-to-Talk over Cellular (PoC) is a communication technology that provides the instant, one-button connectivity of a traditional two-way radio, but transmits the voice data securely over commercial 4G/5G LTE and Wi-Fi networks. This provides users with unlimited, nationwide coverage without the need to build expensive radio repeater towers.
Can Nationwide Push to Talk integrate with my existing two-way radios?
Yes. Teltra specializes in system integration. We utilize Radio over IP (RoIP) gateways to seamlessly connect your existing analog or digital Land Mobile Radio (LMR) network with our Nationwide Push to Talk platform. This allows field workers with PoC devices across the country to communicate directly with warehouse staff using traditional radios.
Are PoC mobile radios legal for commercial truck drivers?
Yes, provided the hardware is deployed correctly. The Federal Motor Carrier Safety Administration (FMCSA) strictly prohibits commercial drivers from holding or interacting with cell phones while driving. Our PoC communication solutions for vehicles utilize DOT-compliant hardware, such as fixed dash-mounts, visor microphones, and tactile Push-to-Talk buttons, ensuring completely legal, hands-free operation.
