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

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.

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)

9
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)
