Fibre-to-the-room (FTTR / FTTRoom)

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 various scenarios, turning the Fiber to the Home paradigm into Fiber to Everything Everywhere.

ITU-T recently published Technical Paper on "Use cases and requirements of fibre-to-the-room". It collects the use cases (including in-home Wi-Fi backhauling, broadband deployment for dense apartment building, network infrastructure for smart office, Internet of things (IoT) support of smart home, low latency service in home networks, fibre deployment for FTTR for residential scenarios, network slicing, eastwest data transmission in home network), where FTTR can be used. Each use case is introduced by a scenario of fibre-based network in home domain and analyses the new demand on network capability.

There was also a Joint ETSI ISG F5G, BBF, CCSA TC6 and ITU-T SG15 Workshop on "FTTR" (Fibre to the room) back in June. The presentations and recording of the event are all available here.

Highlights from XGMF's Conference to Advance Millimetre Wave Technology

On April 1, 2024, two of Japan's leading connectivity organizations—the 5G Mobile Promotion Forum (5GMF) and the Beyond 5G Promotion Consortium (B5GPC)—joined forces to create the XG Mobile Promotion Forum ( XGMF ). This merger symbolizes a pivotal step in accelerating the adoption of next-generation wireless technologies. In May 2024, XGMF's Millimeter Wave Promotion Ad Hoc (Millimeter Wave AH) hosted the International Workshop on Millimeter Wave Dissemination for 5G. This event aimed to foster the adoption of millimeter wave (mmWave) technology in Japan and beyond, drawing an audience of approximately 200 attendees and broadcasting in both English and Japanese. The workshop featured opening remarks by Mr. Naohiko Ogiwara, Director of the Radio Department, Telecommunications Infrastructure Bureau, Ministry of Internal Affairs and Communications (MIC). Key speakers included: Mr. Takanori Mashiko (MIC, slides ) Mr. Sam Gielges (Qualcomm, online - no slides) Mr. Christopher Pric...

How Do Apple AirTags Work?

Apple AirTags have steadily gained popularity in the smart tag market. A recent report highlighted that 69% of smart tag buyers in late 2024 chose an Apple AirTag. This marks a significant rise from 45% in early 2022. In contrast, Tile, the category pioneer now owned by Life360, has seen its market share fall to 11% from 17% during the same period. Samsung's Galaxy SmartTags now hold second place. Interestingly, the technology behind AirTags resembles concepts like Opportunity Driven Multiple Access (ODMA) or Multihop Cellular Networks (MCNs), which I have previously explored . A similar approach has also been discussed regarding Bluetooth-based Ad-Hoc networks . How Do They Work? AirTags primarily use Bluetooth Low Energy (BLE) to communicate with nearby Apple devices that are part of the Find My network. This vast network consists of millions of Apple devices, including iPhones, iPads, and Macs, which can detect AirTags and securely relay their location back to the owner. Addit...

Seamless 5G Connectivity Across Germany on Deutsche Bahn

Rail passengers today take uninterrupted mobile and data connections for granted as much as a smooth journey. Meeting these expectations demands close collaboration between train operators and mobile network providers to deliver consistent coverage along thousands of kilometres of track. Deutsche Bahn’s comprehensive approach to connectivity weaves together network expansion, onboard innovations and the latest digital standards to ensure passengers stay connected from station to station. Since 2021 Deutsche Bahn has been working with Deutsche Telekom to blanket its main lines with high-performance mobile coverage. By supplying speeds of more than 200 Mbit/s on nearly all key routes the partnership reached its original targets two years ahead of schedule. Today passengers enjoy at least 200 Mbit/s on 99 per cent of the 7 800 kilometres of main lines and even 300 Mbit/s or more on 95 per cent. Secondary lines also saw a transformation. Coverage of 100 Mbit/s rose from under 83 per cent ...
