  1. WLAN in Disaster and Emergency Response - WIDER Dag Nielsen & Catherine Mulligan Ericsson Response Workshop on Telecommunications for Disaster Relief, 17-19 February 2003, Geneva

  2. Ericsson Response – our corporate social responsibility • The Programme focus is on Disaster Response, Research and Development and Advocacy • We use Volunteers (ERVs) and Equipment Modules (ERUs) • We partner with Intergovernmental organizations and NGOs with Public and Private sector

  3. WIDER - Background • Currently, most organisations are installing their own communication infrastructure in disaster areas • Organisations working within disaster and emergency response could benefit from a shared communication infrastructure • Provide the same access to tools at the disaster site as in the head office

  4. WIDER Overview • WIDER – WLAN In Disaster and Emergency Response • Vision create an easy to set up, reliable, secure, highly available and flexible system for essential communications services at a disaster site. • Instantiation Design and implement an Ericsson Response Unit (ERU) that provides a home office data communication infrastructure to organizations in the field, enabling them to communicate with other organizations and the outside world in a cost effective manner.

  5. WIDER Participants • WIDER is a co-operation between Ericsson Response, KTH (Royal Institute of Technology), the private sector and international relief organisations. • Ericsson provides a reference group of experts for technology and equipment. • Organisations will provide a reality check of the system and assist with field trials

  6. WIDER Technical Overview Satellite Local Voice Service IX R Se S Key: IX Internet Exchange R Router S Switch Se Server AP Access Point AP AP AP AP Org. network

  7. WIDER – 3 connection scenarios • WLAN • GSM (GPRS/UMTS) • Microwave

  8. WLAN Hotspots • WLAN as office connectivity tool inside the organisations • Fast to set up • Easy to maintain • Every organisation can create their network independently from one another but that network is seen as an extension of the local infrastructure. • Up to 11 Mbps inside the organisational networks

  9. Scenario 1 - WLAN Org B WLAN WLAN – 3Mbps Org C WLAN Org A IX WLAN WLAN Org D Max: 10Kms

  10. Scenario 2 – Mini GSM Org A Org B User A User B Sat User C IX Mini GSM 14.4 kbps data User D 35 Km radius Org C User E External User User F

  11. Scenario 3 – Microwave technology Org B Microwave – up to 34 Mbps Org C Org A IX Org D Up to 50 kms

  12. Internet eXchange - IX • The use of an IX enables efficient interconnection between the Relief organisations • Bandwidth savings • Improved service quality • Different general solutions when designing and IX: • Layer 2 solution: • Switch as central traffic relaying device • Layer 3 solution: • Router as central traffic relaying device

  13. IX Example Interconnecting with direct connection Org 1 Org 2 IX Org 4 Org 3 Interconnecting via third party operated Internet Exchange Point

  14. Service Layer • Connections to and downloads from systems like ReliefWeb and DMIS • Policies on local level to prevent abuse of the satellite link • Email, Web, VoIP demo, Maps, weather information • Open section of network: • Bulletin boards • Press information • Security information • Where applicable: • Connections to local emergency services eg Police/Army

  15. External Links • WIDER should have the flexibility to connect through the following technologies: • VSAT • Inmarsat • Microwave • Cable • To : • PSTN • PLMN • PABX • ISP

  16. Open Issues • Connections to other private networks • Priority handling of emergency traffic over, eg satellite link and public networks. • Input from organisations with experience in disaster response regarding services that they would like to see on the network • Packaging for emergency situations

  17. Advantages Cost Efficiency: WLAN Local traffic prevented from traversing satellite connection Ease of installation Increased technical co-operation between Organisations Organisations can focus on “core business”, rather than infrastructure COTS components Disadvantages Shared infrastructure – one organisation will house the IX and main satellite link Billing mechanisms for shared infrastructure Temporary solution only Advantages & Disadvantages

  18. Evolution of WIDER • Connect WIDER to PABX and private networks • WIDER using QoS mechanisms available in IPv6 • Use of GPRS instead of GSM • Use of UMTS networks – total coverage wherever the emergency crews are using up to 2 Mbps over mobile terminals

  19. Abbreviations • IX Internet eXchange • WLAN Wireless Local Area Network (IEEE 802.11b) • ERU: Ericsson Response Unit • UMTS: Universal Mobile Telecommunications System • GSM: Global System for Mobiles • COTS: Commercially Off The Shelf • GPRS: General Packet Radio Services • DMIS: Disaster Management Information System • ERV: Ericsson Response Volunteer • QoS: Quality of Service
