Here's an Idea

What Corporations need for all businesses is a Business Cell Phone.

It's just one channel you can text, internet optional, and dial only the numbers in the business.

This can work as a walkie talkie for local access only. Secured by its own router and set to internal purposes only...like office mode and travel mode ;-)

Integrate your Email, text w/e to the mobile server and back it up keep it secure, you get it.

This would create competition for current walkie talkies that have the market now. 5Ghz gives you a clean fast signal in open spaces.

5Ghz is picky and likes short open spaces to connect, but hopefully they're improving that hint hint...

Uses AT&T or AT&T to connect with for the low low price of...

Not only that, everyone is connected. Certain restriction would apply due to levels of authority, but any employee could contact any owner at any time.

Its architecture is based around how internal office is structured. Someone will get the request, they'll handle the level of importance and the department will handle accordingly.

Of course you could set the importance on your request to route accordingly, but you get the idea.

This phone only dials the employees of the same business. No outside calls allowed, and if it rings, you better answer ;-)
