G.hn Wi-Fi end points can also be used, or standard Wi-Fi access points added to a media converter, to ensure robust in-room Wi-Fi to maximise speed and throughput in any environment. This is particularly beneficial in MDU situations where congested wireless spectrum, due to large numbers of wireless routers that are all fighting for bandwidth, can lead to poor speeds and connectivity within Apartment Buildings (Figure 5).
usually consist of a controller or master unit and various types of end points that provide the transition back from the G.hn modulated signal to Gigabit Ethernet or WLAN. For ISP or network operators, there are media converters which can work as “network blind”, so they do not have to worry about how to manage and configure them and they can be easily installed by the end customer in their home. It would be equipped with a Gigabit Ethernet interface for connecting to End- User CPE such as a modem or router or any network enabled device such as a smart TV, streaming device, games console, Wi-Fi Access point etc. There is also a coaxial F jack to enable connection to a local TV to ensure reception of any TV services is maintained. When more G.hn EoC end points are used, sharing the same coax medium, the G.hn bandwidth will be distributed fairly between them. The bandwidth will be adjusted dynamically and on demand, while still ensuring that each end point gets its own fair share. When only a single end point needs to transmit or receive data over G.hn, it will utilise the entire bandwidth and as more end points need to transmit and receive, the bandwidth is then evenly distributed between all active end points. This compares well with traditional IP networks, where the bandwidth needs of individual clients are often asynchronous and spiky. In contrast to having a fixed fractional part of the bandwidth statically assigned for the individual MDUs this allows for a much better utilisation of the bandwidth available. It is however still possible to control how much bandwidth that can maximally be consumed by the individual end points. This may be desired by MDU operators, allowing them to limit or upsell more bandwidth to the individual MDUs.

Important to note too is the additional advantage to Building Owners where good Internet connectivity and Wi-Fi can be achieved in every apartment without changes to the building’s structure which would otherwise involve consideration of matters such as fire protection etc, and without any significant service disruption or inconvenience to them or their residents. Summary “Convergence” is a term that was first used many years ago now, but as an Industry we are fast approaching the apex of the converging paths of traditional broadcasting and internet based TV. As Installers adapt and learn new skills to ensure their futures within the Industry, G.hn EoC can play a major part in the upskilling and re-skilling of the Installer base. It is the perfect stepping stone from a past of coax distribution networks across to the world of IP distribution networks.
