Motorola Walkie-Talkie For Communication

 Motorola Solutions is releasing a new version of its APX radio for first responders that adds a touch screen and voice control support to the device for the first time. The APX Next can connect over LTE in addition to offering a walkie-talkie’s standard LMR (land mobile radio) connectivity, and it can even transmit an officer’s location data directly to a dispatcher. While many of these features have been available on smartphones for years, they’re much more challenging to implement on a device meant for first responders, according to Fast Company.

 

The touchscreen has to work in the rain or while using gloves, and Motorola Solutions (which is distinct from the Motorola Mobility smartphone division that’s now owned by Lenovo) had to be careful for the LTE connectivity not to cause interference for the device’s LMR connection. LMR is a vital technology during emergencies when typical cell phone networks can become disrupted or overloaded.

 


The APX Next’s voice control capabilities also have to work differently than they do on smartphones. For starters, they rely on being activated by a button rather than using a wake word. Officers will also have to press a button to hear the result of their query to prevent the voice assistant from accidentally blurting out sensitive information in public. It’s also optimized to work in extremely loud environments, using four microphones to cancel out background noise. 

 

Motorola says the ViQi voice control system will launch with the ability for officers to search for license plate numbers, driver’s license information, and vehicle identification numbers (VIN). In the future, it hopes ViQi will be able to call for vehicle assistance, take statements, and translate languages.  Motorola isn’t commenting publicly on how much the APX Next costs — Fast Company notes that pricing varies too much depending on how many devices are being bought — but the walkie-talkie is available to order now.

A group of people who are using walkie-talkies to talk to one another have to tune in to the same frequency band, which is called a channel. Their radios are all "receiving," so their microphone/loudspeaker units are working as loudspeakers and probably hissing with static, a bit like a conventional radio that's not tuned into any particular station. When someone wants to talk to the others, they hold the push-to-talk button on their handset.

 

Unlike a normal radio, which will only pick up broadcast voices or music from a radio station, a Motorola Walkie-Talkie is a two-way radio: you can both talk and listen (send and receive). The main drawback is that the same frequency channel is used for both things, so only one person can talk at a time. When communication devices work this way, they're described as half-duplex (a single channel allows communication in only one direction at any one time), as opposed to full-duplex (where you can talk and listen at the same time, as on a telephone).
