Terms of the deal were not disclosed.
Cisco says Arch Rock, based in San Francisco, will allow it to offer a metering infrastructure for IP-based smart utility grids. Arch Rock's products are designed to let utilities connect smart meters and other distributed intelligent devices over a multi-way wireless mesh network.
Cisco says the acquisition complements its recently announced alliance with metering company Itron to jointly develop products.
Arch Rock will become part of Cisco's Smart Grid business unit once the acquisition closes, which Cisco expects before year's end.
