RF RANGING PERFORMANCE REDUCED FROM 90M TO 40M - NEEDED HELP

[Anirudh_THABJUL_SB]

Hello Everyone,

I am Anirudh THABJUL, an Electronic engineer working for a company called "SECOND BRIDGE", We are based on Paris.

In our applications, We are measuring distance between two 10 layer PCB's. To achieve this, We are using mainly

1. IMX6 Processor (Main processor)
2. SAM4E (Secondary processor)
3. RF215 + Antennas for RF ranging section

Our issue is when we just measured distance between two PCB by putting the IMX6 in ideal state we are able to range upto 90M (Refer the attachment1) but when we activate the iMX6 for running other applications, ranging is reducing to 40M(50 % performance reduction).

Can any explain this RF phenomenon? If possible please suggest us the possible ways to solve this problem like some reference sites or some reference documents?

Thank you.

Regards,
Anirudh THABJUL
