EMC & Bluetooth
Original Post: EMC (SIG Forum) Date: 2000-07-26
There are a series of benckmarks ensuring a Bluetooth product's ability to
cope with different kinds of signal interferance
- The qualification program requires a product to pass a blocking
requirement which is a fairly high level continuous wave interferer
ranging from 30 MHz to 12.75 GHz.
- There is a test for Carrier to Interferer performance where the
receiver must cope with other Bluetooth modulated signals nearby.
- An intermodulation test where the Bluetooth receiver must cope with
the combination of another
Bluetooth modulated signal and a CW interferer.
- Finally, European EMC regulations will require that the device
operate correctly in the presence of amplitude modulated fields from
80 to 1000 MHZ and a pulse modulated field (simulating GSM) at 900
MHz.
As soon as products start rolling out, these measurements will provide
a fair indication of whether they can cope with difference interferers. |
