  • Our wireless world moves on Professor Michael Walker 3 December 2004
  • Global mobile business
    • more than 1.3 billion people, or 20% of the global population, have a mobile phone, and more than 80% are GSM customers
    • 2 billion people in the world have yet to make a phone call - when it happens it will be on a mobile phone not a fixed line
    500 400 300 200 100 0 Europe Asia North South Arab Africa Russia India East America America Central Asia Other GSM Subscribers Estimate August 2003 (millions)
  • 3G heralds expanding market boundaries anywhere, any time, to anyone connect me to the web or my office interactive services
  • Pipes galore Proprietary technologies IEEE 802 Family 3GPP Family WCDMA FDD WCDMA TDD TD-SCDMA CDMA 1x EV-DO / DV … … IPWireless TDD InterDigital TDD Flarion Navini NextNet ArrayComm Beamreach … . 802.20 802.16e 802.16-2004 (WiMax) 802.11b 802.11a / g / n / s … AirGo licensed spectrum unlicensed spectrum 4G
  • What are they aiming for?
    • Fixed Wireless Access:
      • DSL to homes and business
    802.16e NLOS to MSS (laptop/PDA..) 802.16a NLOS to fixed outdoor antenna 802.16a NLOS to fixed Indoor antenna 802.16 LOS to fixed outdoor antenna BROADBAND WIRELESS ACCESS MSS: Mobile Subscriber Station; LOS: Line of Sight; NLOS: Non Line of Sight 802.16/a Backhaul WiFi WiFi WiFi
  • Hype continues unabated Nextel Steps Up Data Race Unstrung (May 14 2004) – Nextel Communications Inc. has ramped up its Flash-OFDM trial with startup Flarion Technologies, announcing a set of tariff plans that will provide a real market test for the vendor’s “alternative wireless broadband” technology (see Nextel Extends Flarion Trial). BT ready for WiMax drive ZDNet UK (February 23, 2004) – WiMax is creating quite a stir in tech circles and BT is already using it to bring broadband to four rural locations. Could this be followed by a major rollout? Four radio-broadband trials being conducted by BT in rural parts of the UK could be the prelude to a full-scale deployment of WiMax in Britain. Intel’s High Hopes for WiMAX Wi-Fi networking news (Jan 2004) – During a speech at the Wireless Communications Association conference this week, Intel predicted that the next 10 years would be defined by broadband wireless: Intel has become a big supporter of WiMAX, hoping to see Wi-Fi and WiMAX bundled into computers. Siemens plans to develop WiMAX network solution RCR Wireless News (March 2004) – Siemens Information and Communication Mobile Group said it plans to develop a complete solution for WiMAX radio networks, which will be available in the second half of next year. Personal Broadband’s iBurst Service Officially Open for Business at 1 Megabit per Second PR (16 March 2004) - Personal Broadband Australia (PBA) this evening announced that its eagerly anticipated iBurst™ commercial service has been officially launched.. PCCW launches TDD IPWireless broadband in the UK Total Telecom (6 May 2004) – UK Broadband to offer services based on UMTS TDD technology from IP Wireless in a limited area for a three-month commercial trial period. PCCW on Thursday launched a soft rollout of commercial broadband wireless services in the U.K. Flarion announces Vodafone trial PMN (07 May 2004) - Flarion, which provides Flash-OFDM based wireless broadband technology, has announced that Vodafone is trialing its technology in Japan. The agreements adds to Flarion's existing portfolio of trials in South Korea, Western Europe and its commercial deployment with Nextel in North Carolina.
  • Horses for courses? Or Vs ? How to compare:
  • How far it goes depends where your terminal is 3 Sector base station at 25m to: Consider a hypothetical broadband (1Mb/s) wireless network   All figures except LOS based on COST231-Hata model with 10dB shadow margin and no cable losses. System operates at 2GHz with 1Mb/s from 24dBm EIRP terminal TX, 3dB Eb/No, 5dB NF RX. BS antenna = 18dBi
  • How far does it goes depends on data rate 3 Sector base station at 25m to outdoor PC card   100kb/s 1.49km 1Mb/s 0.78km 10Mb/s 0.41km 100Mb/s 0.21km Data Rate Range Site density 1 3.6 15 50
  • How far it goes depends on frequency
  • How far does it goes depends on technology Assumes service to outdoor mobile UMTS TDD: 64kbps UL / 500kbps 3GPP R99 64kbps UL / 128kbps DL Proprietary technology (1) 75kbps UL / 600 kbps DL 1.41 km Proprietary technology (2) 64 kbps UL / 1400 kbps DL 1.56 km Downlink data rate 1.47 km Comparison using 64kbps uplink as reference, what does a single user obtain on the downlink? 3GPP HSDPA 64kbps UL / 700 kbps DL 1.63 km 1.62 km
  • Horses for courses - what do we need? User needs? Complexity Functionality WiMAX IP only No volume billing Direct connect to internet No routing of incoming calls Best effort - No QoS No circuit-switching Static users No handover No roaming 802.16-2004 Flarion Internet HSDPA 802.16e Circuit + Packet Full mobility Incoming call routing Roaming Flexible billing GSM fallback Rich services GSM + UMTS

  • Customer Propositions BRAND Service Enabling Connectivity Access Licenced and unlicenced spectrum Termina l Network operators will become more radio access agnostic – within reason! Access management 802.11 802.16-2004 back-haul & FWA 802.16e 802.20 GPRS WCDMA HSDPA IMS GSM
  • B3G/4G
    • 3GPP study item
    • 100 Mbps dl and 50 Mbps ul
    • improved spectrum efficiency (e.g., 2 - 4 x HSDPA+HSUPA)
    • latency below 10 ms and faster link set-up
    • range of bands -900 MHz, 1800 MHz, 2.1GHz, 2.5GHz
    • scaleable bandwidth [1.25,] 2.5, 5, 10, [15,] 20 MHz
    • increase "cell edge bit rate" whilst maintaining same sites as today
    • inter-working with 3G and non-3GPP systems
    • further enhanced IMS and core network
    disruption reaction lack of vision loss of confidence in process
