Motorola's venture arm invested in privately held Vocera Communications, a supplier of wireless badges that allow retail and healthcare workers to communicate with each other, a Reuters report said.
The Reuters report said Motorola, the world's second biggest mobile phone maker, did not disclose the terms of the investment.
Vocera's system connects a lightweight wearable voice controlled badge that connects to Wi-Fi, short-range wireless networks used within buildings and in public places, the report said.
