Technology Untangled: Add communication flexibility to tablets and smartphones

technology-bourTablets were in big demand as gifts this past holiday season. Many of the more economical choices are Wi-Fi-only devices. They do not connect with the 3G and 4G cell tower networks. As such, their communication abilities are more limited than a smartphone. I was looking for ways to make Wi-Fi tablets more versatile as communication tools and found several interesting applications. Today we will look at apps to turn your Wi-Fi tablet, or iPod Touch, into a push-to-talk (PTT) walkie-talkie, a device for standard SMS texting, and even a free wireless telephone. The PTT apps also work quite well with any standard smartphone.

The walkie-talkie function caught my attention because of a recent series of PTT cell phone commercials from AT&T. It reminded me about how often a short, concise message could be preferable to a cell phone conversation. The popularity of text messaging in place of making phone calls proves the point. But many times a short, immediate voice message can work even better. The dangers of texting and driving also can be avoided by replacing those communications with PTT conversations.

The first app I investigated is called Zello. This free walkie-talkie application works between Android, iOS, Blackberry and even PC. It works over both 3G and Wi-Fi. This means it can turn any tablet into a useful voice communication device. The system beeps with a tone for both sending and receiving, so it is easy to notice the alerts when someone is trying to contact you. I found it useful for getting the attention of my kids by breaking in with my voice while they are absorbed on the tablet with a game or movie. For office settings, however, the beeping could get annoying. I found Zello most useful as a good substitute to texting while driving. It has a clearer sound than my usual speakerphone call when in the car. It also worked well for instant communication while running errands during the holiday season.

Another similar free app is TiKL Touch Talk Walkie Talkie. I think that the interface and execution of this app is subjectively better than Zello, but it only works with smartphones and not with Wi-Fi tablets. TiKL was easy to configure for simultaneous messaging to multiple recipients, making it a viable group communication app. The standard incoming alert tone is a quirky doorbell sound, but it does get your attention. There is also a “polite mode” setting that suppresses your caller’s voice until you answer. This keeps people from launching in to a walkie-talkie conversation with you while you are on an elevator, for example. In place of instantaneous PTT conversations you can also send either short voice messages or text-style chat messages that can be opened by your recipient at their convenience. I like these voice messages better than traditional phone voicemail. It works faster and more efficiently.

Be aware that when using PTT services over your 3G data network that data usage does accrue, so if you do not have an unlimited data plan, keep an eye on your usage. I do not think that Zello or TiKL use anywhere near as much data as a media-streaming feature like Pandora, but I haven’t gathered any specific numbers. In addition, I notice that phone battery life is affected a bit, more so when on 3G than on Wi-Fi.

Texting with a Wi-Fi tablet works well using a free app called TextMe. It works with both Android and iOS. It allows you to do true SMS messaging with any cell phone in the U.S. This app assigns a phone number to your tablet that others can use to send and receive text messages. I notice that I have my tablet in hand more often than my phone these days. It is convenient to be able to communicate via texting without needing to switch over to my phone. For multi-taskers, it makes it easy to talk on your phone and text with your tablet at the same time.

Additionally, TextMe allows you to make and receive free phone calls from your tablet or iPod any time you have a Wi-Fi connection. This essentially turns an iPod into a smartphone, but without the accompanying monthly cellular bill. While the app is free, you need to earn extra minutes by watching occasional ads. You do not, however, use up your minutes when making calls with other TextMe users. So, if your traditional cell phone plan is running low on minutes or has a low monthly allowance, you can call using TextMe from your smartphone and save your cell minutes for when you are on the road away from a Wi-Fi signal.

Another presumably more robust Wi-Fi phone application is available from Skype. It is not free, but you can get a Skype number and buy unlimited phone time for about $3 a month.

Since free Wi-Fi seems to be available virtually everywhere, the communication versatility of a Wi-Fi enabled tablet or iPod will continue to expand, further blurring the lines between smartphones and tablets.•

  1. I think the cops are doing a great job locking up criminals. The Murder rates in the inner cities are skyrocketing and you think that too any people are being incarcerated. Maybe we need to lock up more of them. We have the ACLU, BLM, NAACP, Civil right Division of the DOJ, the innocent Project etc. We have court system with an appeal process that can go on for years, with attorneys supplied by the government. I'm confused as to how that translates into the idea that the defendants are not being represented properly. Maybe the attorneys need to do more Pro-Bono work

  2. We do not have 10% of our population (which would mean about 32 million) incarcerated. It's closer to 2%.

  3. If a class action suit or other manner of retribution is possible, count me in. I have email and voicemail from the man. He colluded with opposing counsel, I am certain. My case was damaged so severely it nearly lost me everything and I am still paying dearly.

  4. There's probably a lot of blame that can be cast around for Indiana Tech's abysmal bar passage rate this last February. The folks who decided that Indiana, a state with roughly 16,000 to 18,000 attorneys, needs a fifth law school need to question the motives that drove their support of this project. Others, who have been "strong supporters" of the law school, should likewise ask themselves why they believe this institution should be supported. Is it because it fills some real need in the state? Or is it, instead, nothing more than a resume builder for those who teach there part-time? And others who make excuses for the students' poor performance, especially those who offer nothing more than conspiracy theories to back up their claims--who are they helping? What evidence do they have to support their posturing? Ultimately, though, like most everything in life, whether one succeeds or fails is entirely within one's own hands. At least one student from Indiana Tech proved this when he/she took and passed the February bar. A second Indiana Tech student proved this when they took the bar in another state and passed. As for the remaining 9 who took the bar and didn't pass (apparently, one of the students successfully appealed his/her original score), it's now up to them (and nobody else) to ensure that they pass on their second attempt. These folks should feel no shame; many currently successful practicing attorneys failed the bar exam on their first try. These same attorneys picked themselves up, dusted themselves off, and got back to the rigorous study needed to ensure they would pass on their second go 'round. This is what the Indiana Tech students who didn't pass the first time need to do. Of course, none of this answers such questions as whether Indiana Tech should be accredited by the ABA, whether the school should keep its doors open, or, most importantly, whether it should have even opened its doors in the first place. Those who promoted the idea of a fifth law school in Indiana need to do a lot of soul-searching regarding their decisions. These same people should never be allowed, again, to have a say about the future of legal education in this state or anywhere else. Indiana already has four law schools. That's probably one more than it really needs. But it's more than enough.

  5. This man Steve Hubbard goes on any online post or forum he can find and tries to push his company. He said court reporters would be obsolete a few years ago, yet here we are. How does he have time to search out every single post about court reporters and even spy in private court reporting forums if his company is so successful???? Dude, get a life. And back to what this post was about, I agree that some national firms cause a huge problem.
