1 Spectrum Management & Monitoring for the Athens 2004 Olympic Games EETT May 2005

2 Outline Introduction Management plan User requests Frequency assignment principles Frequency assignment statistics Spectrum monitoring Results

3 Athens 2004 Olympic Games 202 countries 11,099 athletes Four billion viewers About 7800 frequency assignment requests served Up 50% from Sydney Olympic Games in 2000

4 EETT Mission Goal Continuous, non-intermittent operation of telecommunication systems on a non-interference basis EETT responsibilities Frequency planning License issuance Fee collection To verify that all radio equipments operate according to the terms of their license To ensure a reliable, interference free, radio environment

5 Management Plan Spectrum management Areas of operation (36 Venues) Description of Services Frequency bands per Service Development of e-spectrum web application

6 Management Plan Areas of Operation Attika Region

7 Management Plan Services Cordless Cameras Fixed Satellite Links Land Mobile Radio Service Satellite News Gathering Talkback Service Wireless Microphones Fixed Links Handheld Radios Microwave Mobile Links Telemetry & Telecommand In-Ear Monitors

8 Management Plan e-spectrum Web Application Scope Provide an integrated web-based environment for the management of the administrative procedures involved in the processing of frequency assignment applications Functionalities (from user s point of view) User registration Electronic submission of applications Monitoring the status of applications Receipt of payment orders for the license fees

16 Frequency Assignment Principles ensure that the assigned frequency lies within the tuning range of the available equipment prioritize users and services and select the less noisy spectrum for frequency assignment of critical or sensitivelow power services (e.g. telemetry) assign only 12.5 khz channels for PMR and 10 (30) MHz channels for digital (analog) cordless cameras

17 Frequency Assignment Principles decide upon TX (or RX) spectral isolation in each service and between different services ask from professionals (broadcasters) that isolators should be fitted to all continuous transmission Base Stations ask for the use of CTCSS subtones in order to increase group privacy and avoid receiver squelch opening

18 Frequency Assignment Statistics 7618 applications licensed Only 1.65% applications rejected 95% of frequency assignments within equipment tuning range CC FL FSat HH LMRS MML SNG TBS T&T WLAN Wmics IEM Other Total licensed: rejected: Total:

20 Spectrum Monitoring Staffing and Shifts TOC: Two 8-hour shifts every day (08:00-24:00) OOC: Manned 24 hours, 2-5 persons per shift (continuous monitoring using the fixed stations of National Spectrum Management Monitoring System) Monitoring Units: Two 8-hour shifts, 10 units per shift, 2-3 persons per unit About half of the units were using monitoring vehicles

21 MONITORING ACTION FLOW CHART Problem Identification either from: - EETT On-Site/FX Monitoring Stations Measurements - Ticket Of Complaint issuance Interference Problem on Equipment Licensed User Problem on Equipment; sticker check Unlicensed User Problematic Frequency Assignment Cease of Transmission; -put new sticker -adjust /replace equipment Cease of Transmission; -put new sticker -adjust / replace equipment Communication with EETT headquarters; -provide alternative frequency within tuning range Locate illegal user On-Site; Immediate Cease of illegal Transmission

22 Final Result About applications processed less than 2% denied Euro paid by the users for spectrum fees items of radio equipment accredited Technical characteristics of 568 radio equipment items tested 32 failed 210 shifts for spectrum monitoring units during the Games 25 complaints that required immediate action only one due to frequency assignment Thousands of spectrum measurements at Olympic venues
