DoCoMo unveils walkie-talkie phones

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.
