of the router will have a huge impact on its performance.
Although DOCSIS 3.1, now known as DOCSIS 4.0 (or 3.1 full duplex) is capable of speeds up to 10 Gbps, this cannot co-exist with DTT or Satellite services in a converged system as G.hn can. G.hn technology is technically capable of 10 Gbps but not yet generally, commercially available, although as the need for speed increases going forward, G.hn EoC Products will no doubt evolve to meet that demand. So there are many advantages to using G.hn in coax networks. One core advantage of course is the transmission path being re- purposed, in this case, the coax. More often than not it will be screened and therefore is not so prone to interference from outside sources and will provide far better immunity to EMI. Although the technology behind G.hn is complex, the deployment could not be more simple (Figure 2). EoC in SDU FTTH is revolutionising Broadband delivery to Home Owners and many households manage their needs quite comfortably from a single router positioned near, where traditionally, their main landline telephone socket is located. This may be in the hallway or lounge, or if a newer build property, perhaps under the stairs or utility cupboard in the kitchen. The location
However, all too often, a single router within the property is not sufficient to serve all the needs of the home owner. In many cases, residents struggle to stream or game comfortably around the house. This can be down to many factors, for example, a low powered ISP router, distance from the router to the wireless client itself, wall construction type, airborne interference and Wi-Fi congestion - these can all play a part in slowing down the speed of their connection. This is most noticeable with FTTH where speeds of 500 Mbps or more are not uncommon and can be enjoyed (with the right device) next to, or hardwired to their router. However, in their bedroom or conservatory at the rear of their house, they can end up with very poor connectivity and low speeds by comparison, which lead them to suffer buffering or loss of connectivity. There are several options available to potentially overcome this, and other means of getting the data to where it is needed are often employed. Some are more effective than others and some are more robust and reliable too. Hardwiring, however, is always the preferred choice as this provides the most
