Potential buyers could include private-equity firms and defence contractors including Raytheon, Honeywell International and General Dynamics, Bloomberg reported, citing one of the sources.
The 87-year-old company is working with financial advisers as it looks for a buyer, Bloomberg cited the sources as saying.
The sale process has been going on for several months, though a deal isn't on the immediate horizon, one of the sources told Bloomberg.
Motorola Solutions spokesman Kurt Ebenhoch declined to comment on rumours or speculation.
