Asked by Bradley from Surrey
The article says it all pretty well, actually.
“We were looking for new technology that would increase the efficiency of the hotel’s staff,” says McGuire (Steve McGuire is the director of engineering for the hotel in question). “We wanted the ability to call all employees with the push of a button, as well as the security of having our own system without having to rely on cell phones or paying monthly service fees. And we wanted radios that would integrate with the software and technology we are using.”
Radios have the benefit of offering instant communication, as well as being reliable, affordable and really easy to use. The fact that they are employed in so many areas, from transport, to shipping, to construction work to security (and much more besides), should tell you that they are probably the most cost-effective and reliable communications technology out there right now.
So, to offer a final answer to your question, you will definitely save money if you ditch the push-to-talk cell phones and replace them with two-way radios. In addition, you will almost certainly make your staff more available to customers and thus improve customer service all around. Push-to-talk cell devices aren’t terrible equipment, but they aren’t anything like as proven or reliable as two-way radios or digital two-ways.
