  2. Contents • What is WiMAX ? • Ericsson-FUB • Test results Ing. Francesco Vallone Network Infrastruction Area Responsible CU Enterprise

  3. What is WiMAX? • Acces radio System in 3,5 GHz band • IEEE 802.16d (2004) • No mobility • QOS • IEEE 802.16e • Mobility • Handover • Rural / Suburban environment • Suburban / Urban environment

  4. Wimax transmission elements CPE Outdoor CPE Indoor BTS

  5. Rural Deployment Scenario [1] • Low Density 3.5GHz Rural Wireless Broadband Network Deployment using self-install Indoor CPE + Professional install Outdoor CPE • Basestation serving remote users All ranges for non-LOS BTS to Indoor CPE = 2.5km BTS to Outdoor CPE = >10km

  6. Rural Deployment Scenario [2] • Low Density 3.5GHz Rural Wireless Broadband Network Deployment using Indoor & Outdoor CPE • Low Sited (15m) Basestations serving remote users MicroMAX Low Site Outdoor CPE: 6km All cell diameters are for non-LOS Indoor CPE: 1.2km

  7. WiMAX Deployment Scenario-Outdoor Coverage Real Example (3,5 GHz) Bandwidth ~3 Mbps 30m 30 Km

  8. Sperimentazione FUB-Ericsson della Tecnologia WiMAX 2005-2006 Benevento,11 maggio 2007

  9. Test Scenario Rome Ericsson Campus • BTS situated at the Ericsson Campus, Via Anagnina 203, Rome • Rural and suburban environment, very heterogeneous • CPE location indoor and outdoor • GSM/UMTS co-siting, antennas near various sources of potential interference • Measurements made in LOS e NLOS • Measurements made up to a distance of 3,8 Km • Measurements made at numerous and variuos locations – based on preliminary radio coverage measurements • 60° Sectors

  10. Test Scenario Instruments: Customized VAN • Rohde&Schwarz Receiver up to 7 GHz • Software Platform to measure RF and QoS georeferenced • Sampling of the signal according to “LEE Criterion” in time and space

  11. Test Scenario Instruments: Agilent Vector Analyzer • Vector Signal Analyser Agilent E4443A 3Hz- 6,7 Ghz • Wimax Signal Analyser Tool for IEEE 802.16-2004 Principal Functions: • OFDM Specific Measurements • Bandwith • EVM • Burst Power • Digital Modulation Costellation
