‘Smart street lighting’ technology company Telensa has been selected by the San Francisco Public Utilities Commission (SFPUC) to trial its Public Lighting Active Network (PLANet) street light central management system (CMS) in two locations in the US city.

SFPUC maintains more than 50% of the city’s street lights, and recently announced a new project to replace its high pressure sodium cobra-head style light fixtures with light emitting diode (LED) luminaires.

Telensa’s ultra-narrow band (UNB) wireless CMS will help SFPUC to control switching and dimming of each lamp, measure energy usage, and detect faulty street lights.

"We are delighted to be involved in this innovative trial."

Telensa sales and marketing director Paul Dunn said: "We are delighted to be involved in this innovative trial in San Francisco that demonstrates our ability to add multiple sensor types to the system and create an interactive ‘smart’ network.

"Our PLANet system was developed to meet stringent European standards so uses lower transmission power than US competitor systems yet has far greater range due to our ultra-narrow band wireless technology."

The PLANet system also facilitates significant energy savings as well as reduces carbon emissions.

The system uses information from traffic sensors as part of an adaptive lighting solution, allowing lighting level on roadways to automatically adjust according to traffic flows.

As part of the project, Telensa is partnering with a lighting company, and JAM Services.

The PLANet system is already used by several public authorities in the UK, as well as across the Americas, Europe, and the Asia Pacific region.
