Apparently, such a device does exist, nonetheless it just isn’t extensively commercially available. Based on Brandon Gregg, a poster on Quora.com,
“There actually are “WiFi walkie talkies” for people in the security industry. Most are connected to security officer patrol verification systems that track officer movements, check ins, status reports, etc”.
Basically, WiFi, as a communications format, simply isn’t as dependable during a crisis as the good old-fashioned 2 way radio or walkie talkie. In fact, Walkie Talkie’s (like the Motorola DP3400 series), are normally practical, dependable, high performance and cost effective. They also work right away, with no boot up or load time.
A WiFi comparable would possibly be more costly and probably not nearly dependable enough. Put basically, there just does not look to be a market for it right now. Personally, I doubt that there will be one in the foreseeable future, and you never know.
Also, although it isn’t, strictly speaking, a ‘walkie talkie’, an Android app also exists that performs a similar function as a walkie talkie and operates via WiFi. It’s called, appropriately enough, ‘WiFi walkie talkie’. To cite the app’s write-up on ‘appszoom.com’,
“WiFi Walkie Talkie is a Push-to-Talk application, which allows you to talk for free over wireless networks. With this application, you can transmit your voice data to all devices that are on the same network, or to any (other) device (if) you know its IP address”.
In case you’re really into the concept of possessing a WiFi 2 way radio, then this site is selling a smartphone/walkie-talkie hybrid. The Runbo X5 runs on Android, has a chat time of around 6 and 10 hrs and operates a dual core CPU, it is also highly water resistant. we’ve never reviewed this product, so we cannot say much more than that, but the stats look quite impressive. It even has 4G.
Largely, you’re almost certainly better off sticking to a ordinary walkie talkie or two way radio for your organisation (or personal) needs. There is a plethora of support and help online for use of walkie talkies, also as a variety of comprehensive product reviews (some of that are contributed by yours truly) which will help you make an knowledgeable and cost effective choice.
WiFi can be a technology that’s still evolving, but we’ve all had connectivity troubles with our smart phones, laptops, tablet pc’s and whatnot. The last thing you need should be to suffer identical difficulties when encountering an disaster situation.
Perhaps in the future someone will make a WiFi two way radio, but it’s going to only become a viable alternative to the current versions when it may be proved being safer and offer greater service, which are some things that I just do not see happening. Regretful.
As I have said somewhere else, I’m far from a guru in these things, so if you are feeling like grabbing a second opinion along with your morning coffee, then definately, do a little analysis and get back to me on 2wayradionline.co.uk
