"ITU can play an important role in furthering international standardization efforts (for networked RFID) in addition to raising awareness about the challenges and opportunities of this exciting new technology." That was a conclusion of attendees representing standards bodies, telecoms service providers, vendors and academia at a recent workshop Networked RFID: Systems and Services.

Participants agreed that standardization in the field is essential in order to roll out the technology on a global scale. Experts agree that standards so far have developed in a fragmented way; one example is the to-date weak coordination between different regional bodies. Event steering committee chairman, Pierre-Andre Probst, said that many new work areas have been identified for ITU as a result of the workshop, giving further momentum to work already started in some ITU-T Study Groups. Contributions on RFID are expected in the Study Group meetings taking place in April (Korea, Switzerland and Japan) and based on the outcome of discussions here an action plan will be developed in May.

Radio frequency identification (RFID) is a key part of the so-called Internet of Things, or as one session chair put it: "RFID is part of a larger vision of future technological ubiquity".

Object-to-object communication has the potential to revolutionise commerce, with many areas of business already benefiting from the use of RFID. But there are wide ranging applications for this new technology beyond just making money. For example in Japan there have been trials to use RFID to track children on the way to school, making sure they get safely to their destination. In European ski resorts, RFID ensures that skiers don't have to fish around in their pockets with cold hands for their ski passes now that RFID equipped passes have become widely adopted. A more serious upshot of this application is that now resort managers know how many people are on the slopes at any given time, crucial information in an emergency.

As the technology takes off, increasingly complicated applications are envisaged. RFID systems are moving from closed reader and tag systems to systems where there is a need for a network to share data. While now incipient, presenters at the workshop forecast that the message traffic will increase exponentially over the next 10 years, which will have an impact on existing and future communication infrastructure. And this is where the need for standards becomes more of an imperative.

The 'Internet of things' it was said will lead to a new set of network requirements and capabilities as potentially billions of tags start to transmit data. Network requirements and capabilities for more-complicated services that include sensors must also be taken into account. Sensors can monitor environmental variables. Their combination with RFIDs will not only identify people or objects, but also provide in addition to location other dynamic attributes such as temperature, movement and acceleration.

Specifically ITU expects to examine network and service architecture, requirements for machine-to-machine communication, security, information service protocols, interoperability, data format, radio frequency spectrum allocation, network performance and quality of service in its technical study groups.

As far as security is concerned, consumer protection, namely privacy and data protection, has hindered user acceptance and so addressing this area is seen as a prerequisite for public acceptance. ITU has much experience in this field, particularly in the important area of alignment with policy and regulatory issues.

Global frequency harmonization is a hindrance according to some experts towards achieving supply chain efficiencies and security. This is a topic expected to be raised at the upcoming World Radiocommunication Conference (WRC), Geneva, 2007, and workshop participants suggested the need to establish RFID as a Primary Service.

ITU is also expected to help coordinate ongoing standards work in the field in order to avoid work duplication. Among the groups operating in the area are ISO, ETSI, IEEE, EPCglobal and Near Field Communication Forum.

A new Recommendation identifies the needs required to give end-to-end visibility of client services carried across multi-carrier networks. Without this ability carriers have often had to wait for customers to report problems before they can begin to address them.

The Recommendation - G.8601 - identifies the requirements for the next stage of work which will focus on methodologies to address this issue. Study group experts report that contributions to this end have already
been received.

G.8601 defines architectural requirements for the edge-to-edge management of client services transported over various transport network topologies and technologies. The services for which such management capabilities are required are also included.

The requirements for the transference of the management data between the edge points are described along with the requirements for accessibility to management information at some point in the network, other than the end point.

G.959.1, the Recommendation that increased the capacity for multi-vendor optical interfaces developed to exploit the demand for high capacity Internet routers (see press release), has been updated to help further reduce costs for operators. The use of forward error correction (FEC) as defined in ITU-T Rec. G.709 will allow operators to transport data more cost-effectively through the use of lower cost electro-optics.

 

FEC is a method of sending redundant information with the data in one-way communication in order to allow the receiver to reconstruct the data if there was an error in transmission.

 

Experts say that in the last few years they have seen a shift in demand from operators who are now looking to maximize return on investment rather than increase distance covered etc. The revision of this Recommendation addresses this need. 

 

This work forms part of ITUís ongoing work in optical transport networks (OTN) which encourages a fair market for manufacturers and operators, and ultimately encourages better service for consumers. It has been developed with input from the Optical Interworking Forum (OIF).

ITU-T will publish the first ITU-T Recommendation in the area of free-space optics. FSO is an area dominated by proprietary solutions, the new Rec means that users of FSO systems will be able to co-locate FSO solutions provided by different manufacturers for the first time.

FSO systems use lasers or LEDs to transmit data between two points with line of sight up to 2km. Typically this means between the top of buildings. Data rates of up to 1.25 Gbps are available.

As well as use in fixed settings like between tall office buildings. FSO systems have proven useful in disaster relief where telecoms infrastructure has been damaged and a quick fix is necessary. Equally FSO systems are used where there is no existing infrastructure as a way of avoiding disruptive and expensive cable laying. They are spectrum license free and protocol independent so will happily carry Ethernet, SDH signals etc.

The ITU-T Rec. G.640 will allow the co-location of FSO systems without interference with each other.

International standards that enable interoperability and security in the field of home networking are seen as key to bringing value and versatility to consumers, making possible the use of diverse products, services and sources, and therefore accelerating market development. This was the key conclusion of a successful World Standards Cooperation (WSC) workshop bringing together some 100 experts from industry, the academic community and standards developing organizations, in Geneva, Switzerland, on 2 and 3 February 2006.

Household connectivity is growing rapidly with more and more electronic devices and networks within the home distributing and using digital information and media. In addition, remote control of lighting, heating, appliance-use and security systems attached to the home are making the "digital home" a reality.

The Geneva event provided an overview of these technologies as well as an examination of standards that address access, services, performance, quality of service (QoS), electromagnetic interference, digital rights management (DRM), security issues and overall networking.

Representatives from more than 15 leading industry groups, such as DNLA, DSL Forum and Zigbee, called for closer cooperation between the WSC partners, standards developing organizations (SDOs) and industry consortia. They also agreed that similar events designed to allow for the open exchange of ideas should be held in the future, in view of improving coordination and avoiding duplication of work.  

ITU-T's Joint Co-ordination Activity on Home Networking JCA-HN was recognized by participants as an important vehicle for coordination. The JCA-HN was set up to harmonize work going on across ITU-T Study Groups and to identify what exactly needs to be standardized in the field aiming to produce a roadmap outlining this activity.

Houlin Zhao, Director, Telecommunication Standardization Bureau (TSB), ITU, wrapped up the workshop by reminding delegates of the history of successful cooperation between IEC, ITU and ISO. The three organizations, he said, are committed to promoting and harmonizing the international standardization system, strengthening cooperation among themselves and with all partners concerned. He encouraged the members of the three organizations to support efforts at the international level, as well as the national and company level.  

Opening the two-day event, IEC General Secretary Aharon Amit said that the market, innovation, safety and regulation and competition drive international standards. Chief technical officers, he said, were the best-placed people to decide what is needed and when and this allows the IEC to do its work. In short, Mr. Amit said, "we're seeking guidance from you on what we're doing, what we're doing well, what we're not doing well and what we should be doing."   

In his closing remarks, ISO Secretary-General, Alan Bryden indicated that: "At the recent World Economic Forum in Davos, convergence of information and communication technologies and services for the benefit of consumers was highlighted as a key development, as well as a manifestation of the knowledge revolution, at the centre of the 'creative imperative'". He added that "International Standards have a major role to play" and - referring to the work of IEC, ITU and ISO - "we, ourselves need to converge".

The two-day workshop reviewed the current state-of-the-art in home digital technology from a standardization perspective.  Representatives from 14 leading electronics manufacturers, 10 leading systems service providers, academics and standards bodies examined the situation and needs for standards in relation to:

Ways in which digital services are delivered to the home;

In-home networking;

How content is managed;

How equipment is managed;

Best practices.

Emphasis was placed on trends concerning broadband technologies, the way to ensuring connectivity and interoperability of devices within home networks and on the development of many new application areas - for example, ways in which recent technology can offer non-intrusive monitoring of those with diagnosed medical conditions, or of the elderly.

The World Standards Cooperation (WSC) aims to reinforce, and promote the voluntary consensus based International Standards system of ISO, IEC and ITU.

Study Group 15 has consented a Recommendation that will address a key concern in the evolution to next generation networks (NGN).

With the proposed move to packet switched networks, carriers, mobile operators and system integrators all have a need to support time-division multiplexing (TDM) over packet networks. TDM, experts say, today forms all of the transmission network and a good part of the access network.

The role of this Rec - G.8261 - is to outline the requirements for the support of a crucial part of TDM's operation in packet networks. The Recommendation's authors say that without proper synchronization, applications such as mobile telephony simply will not work.

G.8261 analyses synchronization aspects in packet networks, with particular focus on the Ethernet, and outlines the minimum requirements for the synchronization function of network elements. In particular it focuses on the transport of synchronization information required for the transport of TDM signals over packet networks. The transport of SDH signals is for further study.

January saw a gathering of hundreds of NGN experts in Geneva for the first NGN-GSI (global standards initiative) event. Good progress was reported in several key areas particularly in the important area of functional architecture and requirements for resource and admission control functions (RACF) in NGNs. The Recommendation covering RACF is said to be stable and is expected to be consented at the July GSI event.

The January event comprised three full Study Group meetings (11, 13 and 19). Experts from various other Study Groups were in attendance for this first meeting of the GSI following its launch in November, 2005.

Study Group 13, the lead for NGN work, alone saw over 250 contributions, many a result of the work of the Focus Group on NGN. SG 13 saw three new Recommendations consented, see separate stories (Y.1731, Y.1452, Y.1453).

Study Group 11 reported that 50 contributions were received and launched work on an NGN Protocol Set. According to SG documents ITU-T NGN-Protocol Set 1 will define protocols for the support of:

Network to Network Interface (NNI) session control;

User to network Interface (UNI) session control;

Resource Control Interfaces;

Network Attachment Interfaces.

Protocol Set 1 is targeted for completion by the end of 2006.

The chair of Study Group 19 reported good progress in the area of FMC (fixed-mobile convergence).  

It is expected that many other of the outputs of the Focus Group on NGN will be consented at this July meeting. Among them will be a Recommendation dealing with performance, management and measurement, another key area in NGN. See the work programmes for the various Study Groups involved in NGN for a full list.

A Recommendation consented at the January meeting of Study Group 13 allows enterprises to convert multiple voice streams or VoIP flows to IP packets, enabling them to be trunked to their destination over a packet switched infrastructure, rather than dedicated circuit-switched infrastructure. In this way businesses can reduce costs and benefit from the increased efficiency and speed of IP networks.

Rec Y.1452 gives the required functions and procedures necessary for support of  multiplexed narrowband voice services by IP networks. It specifies the required protocols and the operation of the interworking function.
