All you need to know about Zello

Source:  https://en.wikipedia.org/wiki/Zello


Zello is a tech software company in Austin, Texas, US, known for the Zello app, which emulates push-to-talk (PTT) walkie-talkies over cell phone networks.

History
Alexey Gavrilov developed the product originally called Loudtalks which was announced at the TechCrunch 40 Mobile and Communications Conference on September 17, 2007.[2] Zello acquired the Loudtalks technology, rebranded, and moved the development team to Austin. It added apps on June 20, 2012.[3] Bill Moore is the CEO and Gavrilov is CPO. Moore founded and was CEO of TuneIn where Gavrilov and his team created popular TuneIn applications.

Zello made the news in June 2013 when Turkish protesters used it to circumvent government censors.[4] As a result Zello was the top most downloaded application in Turkey during the first week of June 2013.[5]


In February 2014, it was blocked by CANTV in Venezuela. Zello released workarounds and patches to overcome the blocks to support approximately 600,000 Venezuelans who have downloaded the application to communicate with each other amidst protests.[6] It "has been one of the most downloaded applications in Ukraine and Venezuela."[7]

In July 2017, in Latvia, Zello was the main application which was used by thousands of volunteers and rescuers for communication purposes while looking for Ivan Berladin who went missing.

In August 2017 during relief efforts following Hurricane Harvey in Texas, Zello became a popular method for communications between volunteer rescuers (particularly members of the Cajun Navy) and people stranded by the widespread flooding.[8][9] The app received over 6 million signups in one week as Florida residents responded to hurricane warnings for Hurricane Irma.[10]

In September 2018, while Hurricane Florence caused unprecedented flooding in the US states of North and South Carolina, rescuers used Zello to request information about the locations of people needing help and on street conditions.[11]

On August 27, 2021, the U.S. House of Representatives select committee investigating the 2021 United States Capitol attack demanded records from Zello (alongside 14 other social media companies) going back to the spring of 2020.[12]

Members of the 2022 Freedom Convoy have almost exclusively used Zello to communicate with other members and supporters.[13][14][15]

Products
Zello is an instant communication app to exchange short audio messages. It simulates traditional two-way radios using a walkie-talkie style of communication. The app allows talking one-on-one to a single person or in a channel with a group of people, and offers additional features such as history, replay last message, notifications, and Bluetooth device support.[16]

Zello users can create channels and give control to other Zello users to become moderators. New York Times' technology columnist David Pogue describes Zello's channels, "Like most of the best applications, Zello lets you create groups so that you can carry on something like a party-line phone call among a handful—or hundreds—of friends or collaborators."[17]

Once a channel is created channels can appear on the "Trending" list and creators can assign additional moderators to keep their created channels safe. Though available for Android, iOS, Windows Phone, and Blackberry, Zello can also be accessed from a Windows PC computer with the Zello for Windows PC.[17] For other smartphone operating systems (e.g., Sailfish OS) there are Zello-compatible apps provided by third parties.[18]

Zello Work is the paid service of Zello app that allows corporates and users looking for real-time communication over groups and channels. Zello Work is different from Zello but is however owned by the same company.[19]


What Is Zello and How Do You Use It?

The Zello walkie-talkie app has soared in popularity during hurricane season. Here’s what it is, what it’s not and how to get started.

When it comes to natural disasters, you never know if traditional forms of communication will fail. Of course, you’ll want to make sure that you and your loved ones are safe, but depending on your cell phone plan, constant texting and calling can get expensive. There are a number of hurricane-tracking apps out there, but Zello has become the app of choice for emergency rescuers.

Zello is a free walkie-talkie app for smartphones, tablets, laptops and desktop computers. The app requires an Internet connection to work properly, whether it’s through Wi-Fi or a mobile data network. Unlike the standard calls you can make on the device of your choice, Zello connects you to fellow users and radio channels where large groups can talk regardless of distance.

Unfortunately, if you lose internet in an emergency, Zello won’t be of much use. If you need a truly off-the-grid app, goTenna may be a better alternative, since it enables text and GPS while offline. goTenna requires external attachments to work, but on the upside, it's lightweight and weatherproof.

Android, Apple iPhone 4: What is Super WiFi? (Tech, news, report, Auckland, "iPhone Repair")



The FCC just cleared a path for a new generation of "Super Wi-Fi" technologies. Sounds great! But what the heck is Super Wi-Fi?  http://tiny.cc/superwifi

Super Wi-Fi is still Wi-Fi...

It's not as though Super Wi-Fi is some entirely alien concept. For all intents and purposes, it's Wi-Fi! The same kind of wireless data transmission you use around your apartment or at the office or waiting in line at Starbucks. It's just much, much more powerful.

...but on a new spectrum...

As John explained previously, pretty much all Wi-Fi activity takes place on the same 2.4GHz or 5GHz frequencies. For the first time in 25 years, though, the FCC has opened up a sizable new block of unlicensed spectrum, this time between 50MHz and 700MHz.
...that lives in between your TV channels...

Ever since television went entirely digital, folks like Google have been lobbying, literally, to free up the airwaves between channels. The so-called "white spaces" would otherwise have been lying around unused or been subject to prohibitive regulatory precautions.

...that's much more powerful than what we have today...

Unlike current Wi-Fi airwaves, whose reach can be measured in feet, the spectrum that would carry Super Wi-Fi would be able to travel for several miles because of that lower frequency. Through brick walls, even—something your Linksys really struggles with. You can also anticipate download speeds of 15Mbps to 20Mbps—about as fast as a cable modem.
...that shouldn't interfere with your regularly scheduled programming...

Back in 2008, when the white space plan was first approved, the biggest concern was that using these airwaves for data transmission could interfere with TV signals. To mitigate those fears, white space devices will be required to query a special geolocation database, ensuring no signals are crossed.

...and that will have (literally) far-reaching benefits...

The advantages are already apparent. Google, for instance, already has a trial running in a Logan, Ohio hospital that's giving first responders and the hospital grounds alike super-speedy broadband. Wilmington, NC uses white-space to send real-time feeds from traffic and security cameras. And eventually, you would potentially be able to access your home Wi-Fi from several blocks away.
...though maybe not for a while.
So far, most of what we know about how the white space will be used is based on conjecture. There may be some proof-of-concept devices early next year at CES, and there may be more mass production of products in a year or two. But the first Super Wi-Fi projects are likely to be medical, municipal, large-scale. How long it takes for us to be always connected from anywhere and anything? That's up to the inventors and entrepreneurs to decide. Blog Flux Scramble - Email Encryption and JavaScript Protection Submit Blog Add to Technorati Favorites Add to Google Top Personal blogs

Symbian VoIP SIP Applications for your Symbian Phones (Auckalnd, New Zealand)

There is a lof of free and not really free VoIP clients for Symbian Nokia and Sony Ericsson devices like BaraBlu, AQL, Mobiboo, Skype, RebTel, Jajah, Truphone and possibly others. But we talk now about really free software clients that allows to use SIP gateways on Symbian 9 and Symbian 8 smartphones.

You always can use special edition of Nokia smartphones Ineternet Edition - N80 IE and others. These devices have embedded SIP client that can be configured to work with any SIP gateway server. But what to do with other Symbian smarphones?

We need to install some free SIP client on the smartphone. One of these applications is Fring. Since version 3.0 it allows you to call not only to Skype contacts, but configure a SIP service and directly use it.

Now you can call for free to many countries with SIP services like Gizmo, Free World Dialup or bunch of Betamax services like VoipStunt, VoipDiscount, VoipCheap, NetAppel, Voipbuster, SparVoIP etc. You might be surprised by the quality of the free internet VOIP phone calls and you need pay a cent to any VOIP service provider at all!
