OperatorLink: browser signals of STOP, HOLD and SLOW

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. [1] STOP releases every held direction on every phone and shows a full-screen alert to everyone else. [1] HOLD and SLOW stay on for everyone in the jobsite and are cleared when the last person leaves. [1] Holding a move button keeps sending that move to the other phones; if it stops arriving for 2 seconds, they drop it. [1] One-tap radio-style calls such as Go Ahead, Copy That and All Clear are sent as chat messages. [1] Anyone who joins can take part in a voice call run from the phone browser. [1] The person who starts a jobsite shares a link or QR code, and the crew joins from it. [1] A jobsite link stops working 12 hours after the first person joins it. [1] A jobsite with nobody in it is wiped after 3 idle hours. [1] On Android browsers signals such as STOP make the phone buzz; iPhone Safari ignores the buzz. [1] The app can be added to a phone's home screen as a standalone app. [1] OperatorLink is currently free to use, and no paid plan is built yet. [1] It runs in a phone browser with no app install.

[8] If a dedicated radio is the choice, Peak PTT states its PTT-84G pricing and monthly radio service. [4] If hands-free headsets are the goal, Eartec states that it offers EPak with Lazer-Pro and PRO16 with Monarch. [10] Before choosing, a crew should check the phones, network, equipment, and communication method needed on its own site.

Things to check before you choose

Match the option to the phones, headsets, radios, or other equipment used by the crew. Check what each tool states about communication methods before making a choice. Confirm the costs that each option publishes and what those costs cover. For browser-based tools, check how each person's phone and browser support the needed functions. For headset systems and radios, check the setup requirements for the work being done.
