Push-to-talk technology (PTT), which requires no dial-up and is always "on," started as a way for blue-collar workers like security guards to communicate efficiently, reports the WSJ. But now, some wireless companies are targeting a broader consumer market for PTT services, hoping the feature will catch on with teens who want instant updates from friends and family members who want to stay in frequent touch with one another.
... But push-to-talk service has some major limitations that could affect its appeal to the mass market. The biggest of these: Unlike text messaging, users who buy the service from different carriers can't communicate with each other."

NTT DoCoMo has unveiled a line of 3G phones with a walkie-talkie feature -the "push-to-talk" function- that was first made popular in the United States, reports Reuters.
Telecoms operators worldwide see the feature as a potential new source of revenue in increasingly saturated markets. The feature has allowed U.S. mobile operator Nextel to gain a loyal following of business customers and report one of the U.S. industry's highest average revenues per user.
Both KDDI and Vodafone K.K., Japan's No. 2 and No. 3 mobile operators, are also expected to launch phones with push-to-talk in coming months.
DoCoMo said it planned to target both consumers and business users with the new service, which it dubbed "Push Talk." DoCoMo said there would be a delay of about two seconds before a receiver hears what the speaker said.

Japanese mobile telephone operator KDDI will start a group chat service later this year allowing five users to converse and share text messages and pictures, reports the AFP.
"KDDI, Japan's second-biggest mobile operator, will launch several cellphone models with the new function by the end of the year, with the service available on all models by early next year, the Asahi Shimbun said.
The new mobiles will use technology known as "push-to-talk" for group chatting, in which a user would press a button to open a conversation like when using a transceiver, it said.
Others listen to it simultaneously, with a second member in the group pressing the talk button to carry the conversation on once the first person finishes, it said.
The KDDI service would also enable users to send and share texts and pictures, the daily said without citing sources."

AT&T Wireless is waving a white flag on the walkie-talkie front, according to TheStreet.com.
"The wireless giant had planned to introduce two-way radio service this quarter. But executives on a conference call with analysts Friday said there had been a change of plan.
Instead of preparing their own offering, AT&T Wireless executives said they would work with other carriers to develop a common platform -- delaying the project indefinitely.
To some observers, the move is just a case of a few more wheels coming off the nation's No. 3 wireless player. But others say the decision is a wise concession given AT&T Wireless' pending merger with Cingular".

As cellphone firms prepare Push-to-talk serivces, the WSJ voices industry experts who are questioning whether there is such an immediate demand in Europe. And they note that the region's operators have enough on their plates with the launch of third-generation wireless services.
There may also be cultural differences as well, as "Europeans use mobile phones differently. Text messaging is much more popular in Europe than in the U.S., where paging was a much bigger phenomenon, and push-to-talk isn't as private as text messaging".
"It's another thing that will be much more hyped than used," said Sarah Harris, an analyst at technology consultants Strategy Analytics in Milton Keynes, England.

Nokia sought to prevent a growing row over push-to-talk mobile phone technology with a promise that its networks and software would be compatible with other manufacturers' offerings, reports MSNBC.
"Nokia insists it remains committed to the OMA standard, which is due to be finalized this month. In the interim, however, it is offering its own "pre-standard" technology to satisfy "market demand for a rapid launch. These phones are due to be on the market in the second quarter.
Analysts said Nokia had also diverged from its peers in the development of mobile base stations, and two years ago was pushing its own Enhanced Messaging Service"s.

There are several articles online today on Push-to-talk technology, I'm posting excerpts from the story in the Wall Street Journal, but for anyone who is not a subscriber, there are good articles in both Infosync World and ZDNet UK.
Excerpts from the WSJ
"In autumn, Nokia, Telefon AB L.M. Ericsson ,Motorola Inc. and Siemens AG said they would ensure that all their walkie-talkie handsets and network equipment would work together. But Ericsson said Monday that Nokia, the world's leading cellphone maker, is developing walkie-talkie handsets that won't work with network software from other suppliers.
Johan Bergendahl, vice president of marketing at Ericsson, said Nokia is trying to get a lead on other suppliers, but the compatibility problems "could take years to rectify." An executive at another leading equipment supplier also warned that Nokia's phones don't work with other companies' network software.
In any case, the spat is another example of how cellphone-equipment suppliers have been struggling in recent years to ensure that their products work together, slowing down the rollout of new services. Picture messaging, for example, took off slowly partly because the first consumers to try it found they couldn't send messages to their friends on different networks".

Respondents to February's Unstrung poll (52 percent ) say that a lack of interoperability among push-to-talk (PTT) services offered by separate carriers could be a big hurdle to the widespread adoption of these digital walkie-talkies.
February 28, 2004
Six months ago, an application that allows cell phones to morph into walkie-talkies was heralded as the next big thing in wireless telephony. Suddenly the blue-collar feature was hip and everyone had to have it--never mind that Nextel Communications phones had been equipped with the technology for more than a decade. Read on for Forbes special report outlining the history, the reason for PTT's success and the players.
One company mentioned in the article caught my eye: "Calif.-based Kodiak Networks. A startup, with contracts with European operator Orange and U.S. Alltel, offers interesting additions to the traditional push-to-talk services, including the availability of call waiting during an instant call, the scheduled delivery of voice mail, and the capacity to transform an instant call into a regular call at the push of a button.
Their technology is compatible with both U.S. standards CDMA and GSM and the startup makes the technology available free to handset makers, so a wider array of products should soon be available".
Nextel Communications Inc. and Motorola Inc., faced with a government investigation into the push-to-talk wireless phone service they dominate, hired antitrust lawyers, according to The Chicago Tribune.
"The investigation could result in breaking up their market dominance," said Martin Zohn, an attorney at Proskauer Rose LLP in Los Angeles. "Any company in America that received this request would hire strong counsel."

A new, verbal way to send messages via the GSM network that does not require users to type in a SMS is here, Swedish-based telecommunications giant Ericsson has announced. And, like current text-based SMS's, it costs less than a cellphone call, reports Cool Tech.
"Thanks to Push to Talk (PTT) technology, existing cellular networks can be used to send the equivalent of verbal SMS to multiple recipients, similar to that used by internet chat rooms.
"In order to use verbal SMS, PTT users should register with their respective networks to be PTT-enabled, then set up a “buddy list” on their phones. Each contact that has their phone switched on is highlighted on this list to show they are immediately available. Users can choose to mark themselves as unavailable when in meetings or when they require privacy.
Ericsson felt the US regulations restricting PTT users to one network each was an unattractive solution. Instant Talk, a PTT solution, has been designed with interoperability in mind and it ensures users from different cellular providers can send and receive messages without network problems".
