Walkie-talkie and radio systems maker Motorola Solutions Inc is looking into a possible sale, Bloomberg reported, citing people familiar with the matter.

Potential buyers could include private-equity firms and defense contractors including Raytheon Co, Honeywell International Inc and General Dynamics Corp, 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 rumors or speculation.
