Antenna Performance Over the Air (OTA) Testing

Contact Us Now

Over-the-air (OTA) antenna testing is intended to measure and qualify the entire signal path and
antenna pattern of a wireless device. This makes it vital for use by product development teams, to
identify problems and improve quality of service.

Products and technologies that commonly require OTA testing include:

  • Mobile phones, cellular phones and smartphones
  • Laptops and tablets
  • Mobile payment systems
  • Home monitoring and automation systems
  • Traffic control systems
  • Robotics systems
  • Telemedicine and telehealth products
  • Vending machines
  • Other wireless products

OUR APPROACH TO OTA PERFORMANCE TESTING

As a wireless device manufacturer or developer, the key to success in desired markets is to ensure
that antennas are certified according to CTIA standards; and adhere to both in-country and
international regulations.

Bureau Veritas has the extensive expertise and resources required to support this aim, being a
CTIA-accredited laboratory and approved service provider for prominent brands such as
Vodaphone and T-Mobile.

Recent years have seen an increasing demand for mobile data transmission; wireless communication technology from a single antenna to the direction of multiple antenna development; and the use of multi-antenna spatial multiplexing application to increase the data rate. In addition, it is necessary to address new challenges in antenna implementation posed by increasingly compact wireless devices.

MORE ABOUT OTA TESTING

A mobile OTA (over-the-air) performance test is a radiated test defined by CTIA, which is the
association for wireless devices to verify their three-dimension ‘radiated RF power’ and ‘receiver
performance’.

Its main test items include TRP (Total Radiated Power) and TIS (Total Isotropic Sensitivity) two
categories. However, in WiMAX Forum and Wi-Fi Alliance certification field–CWG-RF (Converged
Wireless Group RF) – is used to name OTA respectively. On the other hand, there are several
wireless communication systems support MIMO, such as IEEE 802.11n, IEEE 802.11ac, HSPA+,
WiMAX, and LTE, etc. At this stage, MIMO OTA Performance testing focuses on the validation of
wireless communication devices’ downlink data throughput in different channel environment.

Bureau Veritas is recognised as a global leader in wireless testing and certification, including:

  • CTIA / GCF OTA
  • CTIA A-GNSS OTA
  • Wi-Fi CWG-RF
  • 2D / 3D Antenna Pattern
  • Vodafone OTA
  • MIMO OTA
