All internet services must use the RJ45 standard of connections. This includes not only for the Internet service, but also applies to telephone, and television. In addition, any communications within the property will also require RJ45 for connectivity. Simply put, the RJ45 cable is the best connection for everything to use.
All new service installations must be fiber optic only. This will mean that no more new coaxial nor telephone lines will be rolled out for internet services. Since the WAN port is an RJ45, the subscriber can choose whether to used a router, or a network server for connecting to the WAN.
