POC radios are set up to look and work like handheld handy talkies, but operate over cellular communications networks.
The radios work within platforms. Most have both closed and open channels.
One of the most recently released radios on the SimplePTT platform is unique, in that it includes voice prompts, making it accessible to visually impaired users.
SimplePTT is leading the way in adding accessibility to their POC radios.
Check the SimplePTT Visually Impaired page for updates.

There are several other radios and vendors in this market, but at this time, the Lucid is one of the best options for visually impaired users.
