The short answer

Push-to-talk, or PTT, means you press a button to speak and the people in your group hear you right away. GroupTalk's page describes a cloud-based push-to-talk system with unlimited range and secure communication. [1] Peak PTT sells push-to-talk radios on a flat monthly rate. [2] OperatorLink passes button presses, chat and voice between phones in a phone browser and shows STOP, HOLD and SLOW to the jobsite crew. [4]

Each one's sources point to different needs. GroupTalk's page ties its system to group communication, alarms and live location tracking for construction sites. [1] Peak PTT's page ties its radios to nationwide talk with flat monthly pricing and GPS tracking. [3] OperatorLink's claims tie it to a free browser tool for a crew that already carries phones. [4] [4]

What GroupTalk, Peak PTT is built for

GroupTalk. Its page says its cloud-based system offers unlimited range and secure communication. [1] It also says supervisors and managers can reach any team or individual instantly. [1] For construction sites, it says live location tracking, alarms and group communication support effective HSE procedures, meaning health, safety and environment procedures. [1] Its page names NCC, Entry, Veidekke and YIT among the construction companies that have chosen GroupTalk. [1]

Peak PTT. Its page describes the PTT-84G as a 4G LTE push-to-talk radio. [2] It describes a delay of under 300 milliseconds between speaking and being heard, no dead zones, no repeaters and no FCC licensing, which is the federal radio license. [2] Its platform supports multiple simultaneous talk groups. [2]

What OperatorLink is built for

OperatorLink is made by the team that publishes this site. It shows STOP, HOLD and SLOW to the jobsite crew and passes button presses, chat and voice between phones in a phone browser. [4] A STOP signal releases every held direction on every phone and shows a full-screen alert to everyone else. [4] HOLD and SLOW stay on for everyone on the jobsite and clear when the last person leaves. [4] Holding a movement button keeps that move going on the other phones; if the move stops arriving for 2 seconds, they drop it. [4] One-tap calls such as Go Ahead, Copy That and All Clear are sent as chat messages. [4] Anyone who joins can take part in a voice call started from the phone browser. [4] The person who starts a jobsite shares a link or QR code, and the crew joins from it. [4]

Pricing and fees

GroupTalk. Its page offers a free 14-day trial. [5] It does not publish a monthly price on that page, so the cost after the trial is not published.

Peak PTT. The PTT-84G radio is priced at $229, with a $19.95 activation fee and $24.95 per month for unlimited PTT, with no contracts. [2] Core radio service is $24.95 per month per radio for unlimited nationwide push-to-talk. [3] Its page describes predictable flat monthly pricing. [2]

OperatorLink. OperatorLink is currently free to use, and no paid plan is built yet. [4]

Setting it up on a jobsite

GroupTalk. Its page says little about how a crew is added to the service, so ask the company directly.

Peak PTT. The company's toll-free number is 855-600-6161. [2] Its page says little about what the crew receives out of the box, so ask the company before ordering.

OperatorLink. The person who starts a jobsite shares a link or QR code, and the crew joins from it. [4] A jobsite link stops working 12 hours after the first person joins. [4] A jobsite with nobody in it is cleared after 3 idle hours. [4] On Android browsers, signals such as STOP make the phone buzz; iPhone Safari ignores the buzz. [4] The app can be added to a phone's home screen as a standalone app. [4]

Things to check before you choose

A crane crew member should ask of any of the three: Does the service reach every part of the site where the crew works, including spots with weak phone coverage? Peak PTT's page describes no dead zones, so ask GroupTalk and OperatorLink how they handle weak coverage. [2] Can a signal such as STOP reach everyone at once, and what happens if one phone drops out? Can the crew hold a phone while working, or are both hands needed for the lift? What does the service cost after the first month, and are there activation fees, contracts or add-ons? Does the crew want voice, button-based chat, or both? How long does a group or jobsite stay open before it is cleared? For how the service behaves with no signal, ask the provider directly.

How to choose

If the crew needs group communication, alarms and live location tracking for a construction site, GroupTalk's page points to that. [1] If it needs dedicated radios on a nationwide network with a flat monthly rate and GPS tracking, Peak PTT's page points to that. [2] [3] If it already carries phones and wants a free browser tool that shows STOP, HOLD and SLOW and passes button presses, chat and voice between phones, OperatorLink's claims point to that. [4] [4] The right pick depends on whether the crew wants radios, a phone-based voice service, or a signal tool in a browser.
