Peter MacAvock (DVB). D Dr Ian Childs attended the very first meeting of the Working Group on Digital Television Broadcasting (WGDTB) which took place in Hamburg in June 1992. He represented the BBC in this meeting and was immediately nominated one of the two vice-chairmen of the group. Since that very first event Ian attended most of the 75 meetings of the WGDTB which later became the DVB Technical Module. In the early days of the work it had to be decided whether or not hierarchical source coding would be used in order to facilitate the transmission of SDTV and HDTV video in one stream. Dr. Childs volunteered to evaluate the consequences of this decision. He found out that the overhead resulting from hierarchical source coding would be so significant that the simulcasting of SDTV and HDTV videos would be preferable. The ‘Childs factor’ thus became one of the fundaments of the work in DVB. In addition to being vice-chairman of the Technical Module Dr. Childs was its special rapporteur on audio. “With Ian’s retirement the Technical Module lost one of its key people and I lost an important advisor and a very good friend” commented Dr Ulrich Reimers, Chairman, DVB Technical Module on congratulating him on his nomination as the first Honorary Fellow of the DVB Project.

    Wireless LAN Technology: Current State and Future Trends

    Wireless LAN Technology: Current State and Future Trends Zahed Iqbal Helsinki University of Technology Telecommunications Software and Multimedia Laboratory [email protected] Abstract In this paper, a comprehensive overview of the current state and future trends of Wireless Local Area Network (WLAN) has been presented. This document stud- ies and compares two most competing commercialy potential WLAN technologies, namely IEEE 802.11 and ETSI HiperLAN. This study also addresses the challenges of their coexistance and convengences towards a global standards. KEYWORDS: Wireless Local Area Network (WLAN), IEEE 802.11, ETSI, HiperLAN 1 Introduction Wireless Local Area Network (WLAN) is a flexible data communication system that can either replace or extend a wired LAN to provide added functionality. Using Radio Fre- quency (RF) technology, or Infrared (IR) WLANs transmit and receive data over the air, through wall, ceilings, and even cement structures, without wired cabling. A WLAN pro- vides all the features and benefits of traditional LAN technologies like Ethernet and Token Ring, but without the limitations of being connected by a cable. This provides greatly increased freedom and flexibility. [8] Wireless Local Area Networks have been used increasingly in many critical applications over the past few years, particularly since 1997 when the first IEEE802.11 WLAN standard was issued followed by its European competitor standard High Performance LAN (Hiper- LAN). In certain locations, the use of WLANs could save millions of dollars in cost and deployment time when compared to permanent wired networks. In other locations, WLAN services are complimentary to existing wired LANs adding the advantage of user mobility.

The top 50 operators accounted for 64% of the world’s pay TV subscribers by end-2020, with this proportion dropping to 62% by 2026. Pay TV subscribers by operator ranking (million) 1200 1000 143 165 38 45 800 74 80 102 102 600 224 215 400 200 423 412 0 2020 2026 Top 10 11-50 51-100 101-200 201+ Excluded from report The top 50 will lose 20 million subscribers over the next five years. However, operators beyond the top 100 will gain subscribers over the same period. Simon Murray, Principal Analyst at Digital TV Research, said: “Most industries consolidate as they mature. The pay TV sector is doing the opposite – fragmenting. Most of the subscriber growth will take place in developing countries where operators are not controlled by larger corporations.” By end-2020, 13 operators had more than 10 million pay TV subscribers. China and India will continue to dominate the top pay TV operator rankings, partly as their subscriber bases climb but also due to the US operators losing subscribers. Between 2020 and 2026, 307 of the 503 operators (61%) will gain subscribers, with 13 showing no change and 183 losing subscribers (36%). In 2020, 28 pay TV operators earned more than $1 billion in revenues, but this will drop to 24 operators by 2026. The Global Pay TV Operator Forecasts report covers 503 operators with 726 platforms [132 digital cable, 116 analog cable, 279 satellite, 142 IPTV and 57 DTT] across 135 countries.

The case of Kenya by Mugo Kibati Submitted the Technology and Policy Program in Partial Fulfillment of the Requirements for the Degree of Master of Science in Technology and Policy May 1999 ABSTRACT The demand for data communications in Kenya is growing at a steady rate. Information technologies have become ubiquitous all over the world, including in developing countries like Kenya. Already, educational, health and trade networks connecting remote regions to the rest of the world are taking advantage of the Internet phenomenon. Banks, insurance and financial services firms, and other corporations need data communications for real time information gathering, automated remote services, intra-corporate voice and data communications, etc. However, like in many developing countries, communications infrastructure in Kenya is woefully underdeveloped and ill prepared to satisfy the increasing demand for data communications.
  • 5G: Issues & Challenges

    5G: Issues & Challenges

    RÉPUBLIQUE FRANÇAISE 5G: ISSUES & CHALLENGES March 2017 The issues and challenges surrounding 5G The telecoms industry is currently in the process of designing the technologies that are due to take over from 4G, which is still being deployed today. A great deal of work is thus underway to prepare these “5G” technologies. To prepare for the arrival of this new generation of technologies, Arcep wanted to take a detailed look at the industry to better understand what is in the works. This report is the fruit of the interviews and research that Arcep conducted over the course of 2016, and which the Authority wanted to publish as a way to contribute to the public debate over 5G. Its aim it to provide as objective and exhaustive an overview as possible, and deliver a concise, informative snapshot of the work that is currently underway on the future generation of mobile networks. This report reflects the views of the stakeholders who were interviewed, but in no way represents Arcep’s positions on or roadmap for 5G. Arcep awarded in 2015 the 700 MHz band and is currently working towards licensing the 3.5 GHz band, both of which have been identified as 5G bands. Arcep is also working with the Direction générale des entreprises and the Agence nationale des fréquences towards enabling spectrum for 5G. Arcep would like to thank all of the entities (listed on the last page) who agreed to take part in this process, and who were willing to contribute to the regulator’s investigation into the development of 4G’s successor.

    Structure of IEEE 802.11 Packets at Various Physical Layers

    Appendix A: Structure of IEEE 802.11 Packets at Various Physical Layers This appendix gives a detailed description of the structure of packets in IEEE 802.11 for the different physical layers. 1. Packet Format of Frequency Hopping Spread-spectrum Physical Layer (FHSS PHY) The packet is made up of the following elements (Figure A.1): 1.1 Preamble It depends on the physical layer and includes: – Synch: a sequence of 80 bits alterning 0 and 1, used by the physical circuits to select the correct antenna (if more than one are in use), and correct offsets of frequency and synchronization. – SFD: start frame delimiter consists of a pattern of 16 bits: 0000 1100 1011 1101, used to define the beginning of the frame. 1.2 Physical Layer Convergence Protocol Header The Physical Layer Convergence Protocol (PLCP) header is always transmitted at 1 Mbps and carries some logical information used by the physical layer to decode the frame: – Length of word of PLCP PDU (PLW): representing the number of bytes in the packet, useful to the physical layer to detect correctly the end of the packet. – Flag of signalization PLCP (PSF): indicating the supported rate going from 1 to 4.5 Mbps with steps of 0.5 Mbps. Even though the standard gives the combinations of bits for PSF (see Table A.1) to support eight different rates, only the modulations for 1 and 2 Mbps have been defined. – Control error field (HEC): CRC field for error detection of 16 bits (or 32 bits). The polynomial generator used is G(x)=x16 + x12 + x5 +1.
