OTA – Over-The-Air Measurements 2019-05-28T16:09:23+00:00

OVER-THE-AIR MEASUREMENTS

We have a well-equipped anechoic chamber and over-the-air (OTA) measurement setup located at Hermia 6 building, Hervanta, Tampere. Chamber provides a stable environment to verify device wireless performance.

Currently supported R&D OTA measurements:

  • Cable (passive) measurement 400 MHz- 6 GHz: 3D radiation pattern, antenna gain, efficiency, polarization
  • Carrier wave power measurement 400MHz – 6 GHz
  • 2.4/5GHz WIFI TRP & TIS
  • Cellular 2G, 3G, 4G, 5G TRP & TIS
  • UHF RFID tag performance testing including ARC/TIPP

Chamber specifications:

  • Size: 3m (width) x 3m (height) x 7m (length)
  • Frequency > 400MHz
  • 2-axis rotation system for 3D measurement
  • 2nd rotation system for RFID measurement

OTA setup consists of following equipment:

  • ETS dual polarization horn antenna 400MHz-10GHz
  • Agilent E5071C 4-port VNA
  • R&S CMW500, options: LTE+CA+MIMO, WLAN 802.11ac + MIMO, BLE HW support
  • R&S NRP2 power meter and NRP-Z11/Z21/Z81 power sensors
  • ETS EMCenter turn table control + RF switch box
  • ETS EMQuest measurement software
  • Voyantic Tagformance Pro RFID measurement system + ARC/TIPP
