On-Ramp Wireless Inc. has added Ivan Seidenberg, the former chairman and CEO of Verizon Communications Inc., to its board of directors. On-Ramp made the announcement March 27.

Rancho Bernardo-based On-Ramp makes electronics for machine-to-machine communications. It serves customers in several markets, including the electric utility and oil-and-gas industries. The business said its products are core components for the “Internet of things,” which is expected to grow.

In the announcement, On-Ramp also said that a second Verizon (NYSE: VZ) alumnus, former Executive Vice President and Chief Technology Officer Richard Lynch, had joined its advisory board.

The venture-funded San Diego business announced in July that it had expanded its series C round to $31 million. Investors include a joint venture of GE Ventures, NRG Energy and ConocoPhillips.
