Wireless Gigabit – IEEE 802.11ad

60 GHz transmission technology is a fairly new wireless communications concept that aims to exploit the 7 GHz of bandwidth available in the 60 GHz unlicensed band. Particular characteristics of this technology have generated special interest within the industry. The main advantages of this high-frequency-range technology are that it enables high data rates and short-range communication applications such as data transfer and uncompressed audio and video (A/V) transmissions. Data rates beyond 1 Gbit/s at up to 10 meters are feasible.

These high data rates can be achieved because of the continuous spectrum and a less power-restricted bandwidth available in the 60 GHz band. Moreover, high path loss enables a larger frequency reuse factor per indoor environment. In addition, the millimeter wavelengths make it possible to have very small radios with multiple antennas solutions, enabling beamforming and beam steering, which enhances the channel capacity and also supports NLOS communications.

The Wireless Gigabit Alliance (WiGig) created a first version of their new specification at the end of 2009. WiGig then worked together with the IEEE 802.11ad group to create an amendment to the well-known IEEE 802.11 WLAN specification in order to enable WLAN operation in the 60 GHz band. This amendment was finalized in 2012.

Rohde & Schwarz offers a unique and comprehensive portfolio of test solutions featuring a wide frequency range up to 67 GHz at one single coaxial input. This makes these test solutions highly suited for the 60 GHz band technology.

  •    R&S®FSU Spectrum Analyzer
    R&S®FSU Spectrum Analyzer
    • First spectrum analyzer with a direct frequency range from 20 Hz to 67 GHz and fundamental mixing
    • Measurements up to 67 GHz – in overrange up to 70 GHz – are possible without using complex setups with external harmonic mixers
    • Simplified test setups with just one connection, an improved level measurement uncertainty and an unambiguous frequency indication without the image response and multiple responses known from external harmonic mixers
  •    R&S®ZVA Vector Network Analyzers
    R&S®ZVA Vector Network Analyzers
    • Direct measurement up to 67 GHz with an overrange up to 70 GHz – particularly suited for manufacturers of RF devices
    • First and so far only four-port vector network analyzer with four signal sources up to 67 GHz for measuring four-port or balanced devices
    • The four sources can be used independently, which is important for intermodulation tests and system applications
    • The R&S®ZVA80/110 further extend the frequency range offering a continuous sweep from 10 MHz to 80 GHz and 110 GHz respectively, which is essential for on-wafer device characterization
  •    R&S®FS-Z60/-Z75/-Z90/-Z110 Harmonic Mixers
    R&S®FS-Z60/-Z75/-Z90/-Z110 Harmonic Mixers
    • Frequency range extension of spectrum analyzers up to 110 GHz
    • The frequency-dependent conversion loss is calibrated over the entire frequency range for accurate and calibrated measurements
    • Balanced design, so that there is no adjustment of bias current needed, a necessary feature for automated measurements
    • The spectrum analyzers also support 3rd party harmonic mixers up to 1.5 THz
  •    R&S®ZVA-Z Millimeter-Wave Converters
    R&S®ZVA-Z Millimeter-Wave Converters
    • Frequency range extension of the network analyzers up to 500 GHz
  •    R&S®NRP-Z58 Thermal Power Sensor
    R&S®NRP-Z58 Thermal Power Sensor
    • Accurate and continuous average power measurements in a frequency range from DC up to 110 GHz
    • Fast, accurate and USB-capable
  •    R&S®SMZ Frequency Multiplier
    R&S®SMZ Frequency Multiplier
    • Signals created by Rohde & Schwarz signal generators are converted to frequency ranges from 50 GHz up to 110 GHz
    • Easy handling and precise, adjustable output levels
    • Optional attenuators are installed in the same housing
  •    R&S®SMF100A Microwave Signal Generator
    R&S®SMF100A Microwave Signal Generator
    • Automatic detection, integration and fully control of the R&S®SMZ via USB, operating like a single unit
    • Frequency and target level at the R&S®SMZ output are directly entered on the R&S®SMF100A significantly simplifying setup and operation
    • No need for additional calibration, particularly important for measurements at different frequencies
