Presentation Overview Introduction to WiMAX

Characterizing WiMAX Transmitters Basestations CPEs

Characterizing WiMAX Receivers Basestations CPEs

Product Overview Conclusion


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 timeFDD: BS and SS transmit on different carrier frequencies at the same timeH-FDD : BS and SS transmit at the same carrier frequency but one at a time

Introduction to WiMAX


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.


WiMAX Networks


Characterizing WiMAX TransmittersBase 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)


Characterizing WiMAX ReceiversBase 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)
