BOOSTXL-CC1120-90: Poor RF communication quality with on board PCB antennas

Part Number: BOOSTXL-CC1120-90
Other Parts Discussed in Thread: CC1190, CC1120

Hello,

First of all I'm pretty new to all this RF communication channels. I'm working on a project where we need to establish RF link over 2-3km. So after doing some research I decided to use this HW platform. 

For testing purpose I was controlling these evaluation boards from TI's "SmartRF Studio 7" software to checkout different combinations of settings. And with just these PCB antennas I was expecting range of around 100-200m.

But I was getting really poor performance in terms of RSSI. Event for very short distance Avg RSSI value was approx. -102dBm .

I was using following settings : 

1.  Frequency : 915Mhz

2.  RX BW : 10kHz

3.  Bit Rate : 1.2 kbps

4.  Deviation : 3.99 kHz

5.  Modulation scheme : 2-GFSK

6.  Tx Power : 26 dBm

7.  Range Extender : CC1190 in 915MHz mode

And here is the photo of that test, so that you guys will have better idea of testing conditions.

And Here is the RSSI log that we got from this test :

Can someone please guide me about how to improve the signal strength or can someone please point out what I'm doing wrong? Your help is much needed and appreciated.

  • Hi,

    Did you set the Jumpers on the Board as per SWRA492?

    Please refer to SWRA492 for Jumper Placements ( Tx Packet Mode on Tx Board and Rx Packet Mode on Rx Board). The following is the link to SWRA492.

    Also please follow the standard settings on the SmartRF Studio.  In your settings I observed you used the Rx Bandwidth of 10KHz. Try to increase it to 25KHz or 50KHz and recheck.

    Thanks,

    PM

  • Hey,

    So setting those jumpers helped.

    Thanks.
