ETSI's Fixed 5th Generation Network group (F5G ISG) has just released its first specification, ETSI GS F5G 003 , entitled F5G Technology Landscape. In this specification, the ISG studies the technical requirements, existing standards and gaps for 10 different new use cases, for home, enterprises or industrial needs. The press release says:  ETSI GS F5G 003 use cases include PON (passive optical network) on-premises and passive optical LAN. In this case, a PON system could connect end devices (like HDTV, HD surveillance cameras and VR/AR helmets) and provide higher data rate, better coordination and controlled latency than current Ethernet and Wi-Fi mesh. The high quality private line use case focuses on optical transport networks (OTN) for governments, large companies, financial and medical institutions who need guaranteed bandwidth, low latency, five-nines availability, totally secured network, access to Cloud services and intelligent operation and maintenance of their connectivi...

Fibre-to-the-room (FTTR) is a new kind of in-premises networking technology which is based on optical fibre communication. With the benefit of optical fibre, FTTR will provide high-bandwidth and reliable transmission. It is envisaged that the topology and functionalities of FTTR technologies may be different from the current fibre-based technologies in transport and access network, and consequently it is necessary to understand the use cases of FTTR and derive the corresponding network requirements for subsequently developing specifications. Earlier this year, I blogged about the ETSI ISG F5G that aims to study the fixed-network evolution required to match and further enhance the benefits that 5G has brought to mobile networks and communications. The intention of F5G is that it will define improvements with respect to previous solutions and the new characteristics of the fifth-generation fixed network. This will open up new opportunities by comprehensively applying fiber technology to...
