Existing coaxial cables are already installed throughout many homes and businesses. When these existing coaxial cables are NOT being used for passing Cable TV/Cable Internet services, these coaxial cables provide a perfect physical medium to create a high performing Internet connection. The combination of low interference coaxial cabling plus the efficiency of the video-optimized G.hn standard enables the best real-world Internet performance. Note: The GCA-7000 will coexist with most services such as Broadband, Satellite, and FTTx, however, it is not recommended in environments where Cable Services (Internet/TV) are being used.
