Why Aren’t There Any WiFi 2 way radios

You’ve probably stumbled upon this looking for information about communication device used by stephen hawking’s, hopefully this will help you answer some of those questions, if not please click on one of the relevant links within the article

Apparently, such a device does exist, but it is not widely commercially available. According to 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 reliable in a crisis as a good old-fashioned two-way radio or walkie-talkie. In fact, Walkie Talkie’s (like the Motorola GP3400 series), are generally useful, reliable, high performance and cost effective. They also work instantly, with no boot up or load time.

A WiFi equivalent would possibly be more costly and probably not nearly reliable enough. Put simply, there just doesn’t seem to be a market for it right now. Personally, I doubt that there will be one in the foreseeable future, but you never know.

Also, although it isn’t, strictly speaking, a ‘walkie talkie’, an Android app also exists that performs the same function as a walkie talkie and operates via WiFi. It is called, appropriately enough, ‘WiFi walkie talkie’. To quote 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”.

If you’re really into the idea of owning a WiFi walkie-talkie, then THIS SITE is selling a smartphone/walkie-talkie hybrid. The Runbo X5 runs on Android, has a talk time of between 6 and 10 hours and operates a dual core CPU, it is also highly water resistant. I’ve never reviewed this product personally, so I can’t say much more than that, but the stats look pretty impressive. It even has 4G.

Overall, you’re probably better off sticking to a regular walkie-talkie or two way radio for your business (or personal) needs. There is a wealth of support and help online for the use of walkie-talkies, as well as a number of detailed product reviews (some of which are contributed by yours truly) that will help you make an informed and cost effective decision.

WiFi is a technology that is still improving, but we’ve all had connectivity problems with our phones, laptops, tablets and whatnot. The last thing you need is to suffer the same difficulties when encountering an emergency situation.

Perhaps one day someone will make a WiFi walkie-talkie, but it will only become a viable alternative to the current versions when it can be proved to be safer and offer superior service, which is something that I just don’t see happening. Sorry.

As I have said elsewhere, I’m far from an expert in these matters, so if you feel like grabbing a second opinion with your morning coffee, then by all means, do a little research and get back to me with a snotty email telling me what a prat I am.

Motorola Posts Disappointing Q1 On Government Slowdown, Narrowbanding Impact

communication device mobileSo to carry on my run of content pieces on this website, I have decided to share one of our favorite content pieces this week. I used to be cautious to include it to the website because I really didn’t wish to offend the original author, but I trust he/she is glad that I enjoyed reading their work and wanted to share it with my readers.

Motorola Solutions(NYSE:MSI) recently announced a weak set of Q1 2014 results, as government revenues fell 11% and operating profits by 21% over the same period last year due to a higher-than-expected overhanging impact of narrowbanding in North America. A sustained decline in the federal business also had an impact on government revenues, and the company expects only a modest improvement this year from the government shutdown-related lows of last year. The companys enterprise revenues, excluding iDEN, declined just 1% over the same period last year recovering gradually from recent macroeconomic uncertainties and offsetting some of the impact of the under-performing government division. Motorola expects the demand environment, especially in the government business, to remain challenging in the near term, with government sales expected to decline by 8-11% in the second quarter.
In order to focus singularly on its government business, which accounts for almost 70% of its total revenues, Motorola has decided to sell off its enterprise division to Zebra Technologies for $3.45 billion in cash. The company expects the deal to close by the end of the year, following which the excess capital will be returned to shareholders in a timely manner. The enterprise sale provides Motorola with an opportunity to restructure and reduce costs in keeping with the current business environment. Motorola expects to cut around $200 million in operating costs over the next 18-24 months. We have a slightly revised$65 price estimate for Motorola, whichis about in line with the current market price.
Narrowbanding And Federal Impact
One of the biggest reasons that Motorola mentioned for its top-line under-performance last quarter was its lower-aged government backlog in North America. The company acknowledged that it underestimated the impact of narrowbanding in previous years, which had led to record years in 2012 and 2011.Motorolas government revenues in those years were boosted by thenarrowbanding mandate issued by the Federal Communications Commission (FCC), which necessitated a switch to a more efficient spectrum band for public safety operations. With most of the narrowbanding-related equipment upgrades now complete and government agencies going slow on their capital spending, Motorolas government businessfaces near-term growth concerns.
The tough year-over-year comparison was accentuated by a challenging federal environment in the aftermath of the recent government shutdown in September. In the fourth quarter, Motorola had suffered a revenue hit of about $150 million in its federal business. Since most of this shortfall wasnt deferred, Motorola was unable to recoup the losses in Q1. The federal slump should continue in the near term, with government sales expectedto decline by about 9.5% at the mid-point of guidance. However, for the full-year, the company expects a solid back-half recovery to help stem the slide to the low-to-mid single digits. The downside is limited by the fact that public safety is usually down the priority list of areas in which governments will look to cut their spending. As a result, we see any further impact to government revenues from sequestration, or the spending cuts that the federal government started implementing, being fairly muted.
LTE Transition And Margins Key To Long-term Fundamentals
Going forward, we see the adoption of LTE for public-safety use, along with the broader trend of analog-to-digital shift in the U.S. and internationally, as the key drivers of Motorolas value. U.S. public safety spending in the coming years will be bolstered by the job creation bill passed in 2012 that reallocated the D Block spectrum for public safety use and provided a funding of $7 billion to build out a nationwide network over eight years. We expect Motorola to benefit from the stickiness of its government customers as well as its strong market position and large installed base of security devices to grab a big chunk of that market going forward.The companys recent launch ofAPX 7000L, its first radio – http://www.easytechsrl.net/?p=51 – that works both on legacy LMR (Land Mobile Radio) and next-generation 4G LTE networks, bolsters our view that Motorola has positioned itself strongly to benefit from the LTE transition in the years to come (seeMotorola Solutions Sharpens LTE Focus With First 4G-Capable Radio For Public Safety).
It is also a good sign for the future that the company has been successful in driving efficiency through its operations over the last couple of years, and expects to accelerate those efforts in the coming quarters. Despite the top-line concerns and significant operating leverage in the business, Motorola expects operating margins to improve by almost a percentage point to 18.5% in 2014, benefiting mostly from the the cost controls in place as well as the $200 million in cost cuts expectedover the next two years. Going forward, we expect the operational efficiencies to more than offset the gross-margin decline that could result from rising competition in the coming years as rivals increasingly address the ongoing transition of public safety networks from analog to digital.
