Other organizations

On February 25, 2009, three home networking organizations that promoted previously incompatible technologies (CEPCA, HomePNA and the Universal Powerline Association), announced they agreed to work with Homegrid Forum to promote G.hn as the single next-generation standard for wired home networking, and to work to ensure coexistence with existing products in the market.

On October 2008, the Continental Automated Buildings Association (CABA) and HomeGrid Forum signed a liaison agreement to support HomeGrid Forum’s efforts in conjunction with ITU-T G.hn to make it easy for consumers to connect devices and enjoy innovative applications using existing home wiring.

On July 2009, HomeGrid Forum and DLNA signed a liaison agreement “setting the stage for collaboration between the two organizations and the approval of G.hn as a DLNA-recognized Physical Layer technology”.

On June 2010, Broadband Forum and HomeGrid Forum signed an agreement to deliver a compliance and interoperability testing program for products using G.hn technology. The Broadband Forum will support HomeGrid Forum’s validation of G.hn products, their promotion of product conformance and interoperability, and help expedite the total time to market for HomeGrid Forum Certified products. On May 2011, both organizations jointly announced the first open G.hn plugfest.
