MOTO Talk is a feature on some Motorola 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 called it 'DirectTalk' and included it as a free service on most new models of Motorola handsets. Boost Mobile disabled 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."

| - MOTO Talk es una función que tienen algunos celulares iDEN que permiten hacer llamadas PTT (Pulsa y habla) a otros fuera de la red iDEN. Esta función tiene diferentes nombres dependiendo del proveedor de servicio iDEN. En los Estados Unidos, Nexter lo llama "DirectTalk" y lo incluye como un servicio gratuito en la mayoría de los equipos recientes de Motorola. Boost Mobile deshabilita la función por software. SouthernLINC lo llama LINCaround y envía los equipos con la función deshabilitada. Puede habilitarse después de pagar $20 por la activación. En Canadá, TELUS lo llama "Mike's Talk-Around". Es el mismo sistema usado por los walkie-talkie de la serie DTR de Motorola, pero los DTR y los equipos iDEN se configuran para que no se puedan comunicar entre ellos debido a su configuración de software. MOTO Talk no es igual que el servicio pulsa y habla "DirectConnect". Las señales son enviadas directamente al otro equipo, sin usar la red celular como lo hace DirectConnect. MOTO Talk usa la Banda ISM de 900 MHz diferente a las frecuencias del servicio IDEN, que por lo general está en 800MHz en los Estados Unidos y Canadá. El rango efectivo puede ser como máximo de 6 millas, pero las frecuencias usadas son bloqueadas por estructuras y vegetación. El rango práctico está dentro de 1 a 2 millas. (es)
- MOTO Talk is a feature on some Motorola 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 called it 'DirectTalk' and included it as a free service on most new models of Motorola handsets. Boost Mobile disabled 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. Motorola Solutions Inc sells DTR series two-ways radios that carry this peer to peer protocol. It can be used for voice communication, as well as SMS (short message services) between devices over more than 8 miles in flat terrain conditions. 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" or "hop sets" or "frequency hop groups" 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 8 miles in flat terrain, 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 462 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 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 code 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 technology on the 900 MHz ISM band as an unlicensed transmitter. They use similar commercial radio transmission systems for DTR Digital series businesses but they are not compatible with each other, because they are configured differently by software. (Deliberately made by Motorola) In the DTMT Mode they transmit with 600mw and in the band ISM of 900 MHz (902-907, 915-928) they use the type of digital modulation 8-level FSK 900 MHz ISM FHSS. In 10 channels and 15 codes (can be made safer using the radio's own ID) Frequency Hopping Spread Spectrum is a spread spectrum modulation technique in which the signal is emitted Over a series of seemingly random radio frequencies, jumping from frequency to frequency synchronously with the transmitter. Unauthorized receivers will hear an unintelligible signal. If you try to intercept the signal, you would only get it for a few moments and hear data. A broad spectrum transmission offers 3 main advantages: 1. Signals in spread spectrum are highly resistant to noise and interference. 2. Signals in spread spectrum are difficult to intercept. A transmission of this type sounds as a short-lived noise, or as an increase in noise at any receiver, except for the one using the sequence that was used by the transmitter. Broadcast spectrum transmissions can share a frequency band with many types of conventional transmissions with minimal interference. 3. The signals can not be interfered in a conventional manner (blocking the TX / RX frequency). More sophisticated equipment such as Jamming equipment that interferes with the entire frequency band must be used. (en)
