The Motorola TLK-100 is a broadband push-to-talk device that communicates over 4G LTE networks through an embedded MFF2 UICC SIM card rather than conventional two-way radio frequencies, using the OPUS voice codec and Motorola's WAVE platform to extend push-to-talk coverage beyond line-of-sight or repeater range. It stores up to 8 channels, expandable to 96, and 300 contacts, and includes GNSS/A-GNSS location tracking across GPS, GLONASS, Galileo and BeiDou, along with Bluetooth v4.2 BLE and 802.11 a/b/g/n Wi-Fi for accessory and network connectivity. AES-256 encryption is built in for secure communications. The unit weighs 166g with its 2300 mAh battery, rated for approximately 18 hours of use on a 5:5:90 duty cycle, and carries an IP54 rating for dust and water intrusion along with MIL-STD testing for thermal shock, humidity and packaging.
