Positron’s G.hn technology provides managed non-blocking symmetrical Gigabit bandwidth services to subscribers over existing telephone wire or coaxial cable on extended distances, at a lower cost and with reduced complexity compared with G.fast.
The ITU-T G.9960 G.hn Wave-2 standard is designed to leverage the existing telephone, UTP, CAT-3 or CAT-5/5e wiring or RG-6/RG-59 coaxial cable to deliver a Gigabit Internet service to each subscriber without the complexity and delays associated with in-building fiber installation. G.hn is increasingly used as an Access Technology by Operators looking to simplify their access network and backend infrastructure with an Ethernet-like technology that is highly scalable without some of the inherent complexity of DSL-related technologies. With G.hn, Operators deliver advanced services such as Gigabit High Speed Residential Internet and 4K IPTV 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 over the existing telephone wire or coaxial cable. The Positron GAM solution is MEF CE 2.0 compliant and is ideally suited to deliver Business Ethernet services in an MDU and/or MTU deployment.
G.hn consistently delivers superior bandwidth over twisted pair wire and coaxial cable. G.hn dynamically adjusts the allocation of the bandwidth between the downstream and upstream direction to reflect the real-time traffic conditions for optimal and near-symmetrical performance under all conditions.
When operating on twisted pair, G.hn can operate either on a single pair (SISO) or by bonding two (2) pairs on a single port (MIMO) to extend the reach of a Gigabit service to 250 meters. The results were obtained by the TNO Institute (Netherlands) on 24 AWG (0.51 mm) wiring.
G.hn leverages the coaxial infrastructure to deliver Gigabit performance over a distance of 800 meters on RG-6 cabling typically used inside MDUs and homes. When using a standard coaxial splitter, it is possible to serve up to 16 subscribers per G.hn port.
