Imagine community-wide Wi-Fi an industry standard in multi-dwelling environments. This is possible through the deployment of G.hn technology.
G.hn, an International Telecommunications Union (ITU-T) standard, is an access technology for operators looking to simplify their access network with an “Ethernet-like” technology.
With G.hn, operators deliver advanced services, such as gigabit high-speed residential internet and 4K internet protocol television without the high capital and operational expenses associated with a fiber retrofit. Each G.hn subscriber port supports up to 1.7 Gbps of dynamically allocated bandwidth for near-symmetrical gigabit services. This enables providers to deliver a gigabit internet service to each apartment inside a multi-dwelling unit or a multi-tenant unit without the cost, complexity and delays associated with in-building fiber installation.
As deployed by Positron Access, G.hn is increasingly used by our partners to sustainably improve connectivity in multifamily communities. These partners offer in-depth analysis of cabling specifics and electrical as-built drawings of active properties to design a custom wiring solution to accommodate, rather than replace, each property’s unique, pre-existing infrastructure.
Proven Benefits of Fiber Service Extension Applications
Our partners leverage their expertise of the Positron G.hn Access Multiplexer to enable MDU property management companies to offer lightning-quick, cost-effective, and dependable Gigabit internet speeds to their tenants in MDUs. Property management companies can then improve their service levels without the need for any building retrofit, which can be expensive and disruptive. Property management companies expand the services they deliver with an impressive ROI and minimal capital outlay.
The transformative nature of G.hn applications will make community-wide Wi-Fi an industry standard in multi-dwelling environments. With the broader installation of smart building systems including cameras, sensors, environmental controls, and asset tracking systems as crucial amenities for an improved resident experience, residents will come to view community Wi-Fi systems as another essential building asset. Owners that do not keep up with these developments will see the quality and capitalized value of their community suffer.
Positron’s partners have developed a proven process to ensure a successful and sustainable deployment in existing brownfield properties.
In-Depth Site Surveys
The site survey process begins with a careful analysis of each property’s unique needs. Built from the ground up, the solution is designed to accommodate each property’s unique blueprints and connectivity requirements. Site surveys are extremely important to ensure systems are updated in the most economical way for each property’s connectivity requirements.
The deployment process is aligned to complement, rather than disrupt, established occupancy turn processes. With little to no downtime, the installation enables property-wide connectivity, giving residents the opportunity to immediately connect to the internet, without reauthorizing as they move about the property.
Sustainable and scalable
Positron’s partners provide subscribers with an extensive support team, dedicated to each property’s continued development and operation, designing customized, future-proof solutions to ensure the network is both a sustainable and buildable foundation for upcoming technologies like Web 3.0, Wi-Fi 7 and 5G. G.hn technology is designed to be adapted and improved upon to grow in tandem with each property, working together to accommodate any future needs that may arise.
The installation of the GAM solution by Positron’s partners highlighted the importance of a careful pre-deployment site survey and this is applicable to coaxial and telephone wiring re-use with G.hn.
For MDUs where the telephone wiring will be re-used, the continuity of pairs currently used for VDSL2 or even telephone service, there is no additional validation required since G.hn is permissive and will operate without further pair qualification or grooming. For unused pairs, it is important to perform a continuity test using the same tools and techniques used for the last 20 years for xDSL. Bad pairs can then be identified and repaired as needed.
When re-using coaxial cabling, understanding how each room or apartment is connected is important. Most MDUs are cabled with “home run” coaxial cabling to a common location where taps or splitters can be installed in a point to multipoint mode to reduce the connectivity cost of each subscriber. Unlike CATV and DOCSIS, G.hn does not require coaxial amplifiers and fine tuning with attenuating taps. If co-habitation with CATV is required, the G.hn signal shall be injected downstream of the CATV/DOCSIS amplifier with a simple 2:1 combiner device. Otherwise, if migrating to IPTV or streaming, these amplifiers and attenuating taps shall be removed as they are no longer useful.
For some properties, the option of a comprehensive site survey is not always an option. For instance, a property of about 450 doors no longer had up to date coaxial cabling diagrams. In this case, rather than spending days “toning out” each coaxial drop with specialized equipment to document the coaxial infrastructure, we recommend installing the GAM devices in each wiring closet and pre-install the G.hn endpoint devices in each room or apartment and to record serial number of each device against the room or apartment number. Using the endpoint auto-detection feature for each coaxial port of the GAM, it is then simple and efficient to use this information to fully document which door is served by each coaxial segment.
Overall, we learned that G.hn is robust and rather forgiving with regards to “less than stellar” existing wiring. You can plan fiber extension by re-using the existing wiring in your building without too much concern about potential complexity, cost, or performance issues.
