Bluetooth test services | Bluetooth certification testing providers

This page covers bluetooth test services provider capable to certify bluetooth devices as per Bluetooth specifications. It mentions various bluetooth test and measurements performed during bluetooth certification testing.

What is Bluetooth

Introduction: It is a global wireless standard which allows wireless connections between range of electronic devices such as mobile phones, medical devices, PCs, headphones, wireless speakers etc. It eliminates need of wires by connecting devices wirelessly over short distances (about 100 to 150 meters) using 2.4 GHz ISM bands. Bluetooth is mainly used for low data rate high quality data transmission/reception as well as for streaming audio between devices.

Bluetooth certification test parameters

There are various versions of bluetooth standard incluing v1.0, v1.2, v2.0, v2.1, v3.0, v4.0, v4.1, v4.2, v5.0 and v5.1 (latest). The bluetooth versions 4.1 and above are referred as Bluetooth Low Energy (BLE). Bluetooth device certification should cover various specifications as published by bluetooth SIG under these specifications. The major bluetooth certification test parameters are as per radio, physical layer, link layer and so on.

Following are the basic physical layer and radio characteristics to be verified during the bluetooth certification by respective test providers.
• Frequency bands (2400 to 2483.5 MHz)
• Modulated power spectrum as per GFSK/π/4-DQPSK/8-DPSK.
• Frequency deviation (It should be smaller than 115 KHz for BR/EDR, and less tha 185 KHz for LE.)
• Frequency hopping (1600 hops/sec or 3200 hops/sec
• Transmit power and range
• Receiver sensitivity (It should be -70dBm at 0.1%BER for BR and LE modes, and -70 dBm at 0.01%BER for EDR mode. )
• Maximum data throughput
