  1. Advanced Measurement Techniques for Testing WiMAX PHY/RF

  2. About SeaSolve • SeaSolve Software Inc (SSI) is one of leading suppliers of real-time test and measurement solutions for testing and analyzing the performance of IEEE 802.15.4/ZigBee (WPAN), IEEE 802.11a/b/g (WLAN), IEEE 802.16-2004 (WiMAX) and IEEE 802.16e (Mobile WiMAX) transceivers. • SeaSolve is headquartered in San Jose, CA, USA. • National Instruments Alliance Member • WiMAX Forum Member company

  3. Presentation Overview • Introduction to WiMAX • Characterizing WiMAX Transmitters • Basestations • CPEs • Characterizing WiMAX Receivers • Basestations • CPEs • Product Overview • Conclusion

  4. Introduction to WiMAX • IEEE 802.16-2004 standard for fixed broadband wireless access (FBWA) • 256-carrier OFDM; bandwidths 1.25 to 20 MHz; carrier frequencies up to 11 GHz • High data rates with wireless metropolitan area coverage • Deployed in TDD, FDD, or H-FDD configurations • Base Stations (BS) and Subscriber Stations (SS) in PMP configuration • TDD : BS and SS transmit at the same carrier frequency but at different time • FDD: BS and SS transmit on different carrier frequencies at the same time • H-FDD : BS and SS transmit at the same carrier frequency but one at a time

  5. General WiMAX Frame Downlink (DL) sub frame :Preamble, Header and one or more DL bursts and transmitted by BS Uplink sub frame : Slots for initial ranging, BW request and data transmissions from various SSs.

  6. WiMAXNetworks

  7. Characterizing WiMAX Transmitters Base Station& Subscriber Station • Visualize the data as channel response, EVM/symbols, EVM/sub carriers etc. • Neutralizes front end non idealities from the IQ data • Dynamically detect CP used by Base station from the Base station Preamble • Analyze BS and SS transmission in H-FDD and TDD modes • Configure RF Settings (Trigger, Span, Ref level Acquisition length and Center frequency)

  8. Characterizing WiMAX Receivers Base Station& Subscriber Station • Generate Real world WiMAX RF test signals • Transmit TDD frame for BS & SSs • All Measurements in one solution • Generate impaired RF/Baseband data • Transmit and Save the configured IQ data with MAC information • Configure downlink and uplink bursts profile • Configure RF Settings (Power level, Center frequency and Bandwidth)
