CC2538: CC2538 Range Test

Part Number: CC2538
Other Parts Discussed in Thread: Z-STACK

Hello sir,

I am able to transmit the ADC data from ZED to ZC.

I have tested the range of this it's about 1 and half meter only by using on board antenna in closed room. what is the default I tx power set in the z-stack? and where can i find it in z-stack? is it is fixed in z-stack to 7dm?.

i went through the document of CC2538 the output nominal power is 7dbm so, i want to increase the tx power to 7dbm.

i have done PER TEST with various programmable tx power given in PER TEST Menu(7dbm,3dbm,0dbm,-3dbm,-9dbm,-15dbm), i have good results with 7dbm upto 6 meters.

If the tx power 7dbm is already set in z-stack why the connection is limited upto 1 and half meter in the same environment where PER TEST is done.

i want to change the onboard antenna to external antenna which is SMA antenna for better range. what are the to be considered?.

I don't want to use the range extenders(cc2591 and cc2592) because of power consumption.

please clarify the issuses

Thanks and Regards
