MOTO Talk is a feature on some Motorola
Motorola
Motorola, Inc. was an American multinational telecommunications company based in Schaumburg, Illinois, which was eventually divided into two independent public companies, Motorola Mobility and Motorola Solutions on January 4, 2011, after losing $4.3 billion from 2007 to 2009...

 iDEN cellular phone handsets which allows users to make short-range 'push-to-talk' calls to other such handsets without being on the iDEN network. This feature goes by different names on iDEN service providers. In the US, Nextel calls it 'DirectTalk' and includes it as a free service on most new models of Motorola handsets. Boost Mobile disables the function via handset software settings. SouthernLINC calls it LINCaround and ships handsets with the feature disabled. It can be enabled after paying an activation fee of $20. In Canada, TELUS calls it "Mike's Talk-Around."

It is the same system as used with Motorola's stand-alone DTR-series walkie-talkies, but DTR handsets and iDEN handsets set to MOTO Talk are not able to communicate with each other due to software settings.

MOTO Talk is not the same as the on-network 'DirectConnect' push-to-talk service. Signals are sent directly from one handset to another, rather than using the cellular network as DirectConnect does. MOTO Talk uses the 900 MHz ISM band

 rather than the frequencies allocated for iDEN cellular phone service, usually in the 800 MHz cellular band in the US and Canada.

There are ten "channels" available in MOTO Talk, and fifteen privacy codes per channel. In addition, "private calls" can be placed using the phone number assigned to the handset being called.

The effective range can be in excess of 6 miles, but the frequencies used are line-of-sight and are blocked by structures and vegetation. Practical ranges are usually 1 to 2 miles.

The MOTO Talk service is slightly similar to FRS (Family Radio Service

) walkie-talkies but uses digital rather than analog signals, operates on the 900 MHz ISM band rather than the 465 MHz frequencies allocated to FRS, and uses frequency-hopping spread spectrum technology rather than single fixed frequencies for each channel.

On each phone the MOTO Talk entry varies between 'MotoTalk' and 'DirecTalk' depending on the age of the phone and the branded carrier (Boost Mobile or Nextel). Otherwise, they are the same identical function with a different name. Boost Mobile phones are not enabled for MOTO Talk use by default but can enabled by modifying the codeplug of the device (The Motorola i415 has the codeplug entry but not the needed transceiver hardware. As of 2011, it is the only device from Boost on the iDEN network that cannot use MOTO Talk.)

The off network feature on the iDEN phones work for up to a six mile radius and will communicate with all other iDEN phones in the area on the same channel and code access number.

The off network walkie talkie feature has a total of 10 channels on newer phones and within those 10 channels, the phones can handle 15 separate group codes. This means there can be 15 conversations operating on each of the 10 channels within any single 6 miles radius. As with FRS and GMRS radios, the 15 group codes work to block calls that are not on the same code. The group codes do not secure your conversation. Only one person can talk on a channel at a time. The phone can listen to all activity on a channel, but cannot transmit when in this "receive-all" mode. It uses FHSS
