Testing the long range feature of nRF52833 chip

Question

Dear Nordic， 
 We developed a product based on the nRF52833 chip, with an external antenna, 3dBi gain. Use a smartphone to scan the product in the outdoor，the transmission distance I got for 8 dBm TX power and interval 100ms on 1M PHY was 185 meters. I want ask that How long the distance can nrf52833 transmit upto 8 dBm TX power and interval 100ms in an open and unobstructed and non interference environment? We want to compare the transmission distance which is very helpful for us to improve the product. 
 It'd be really great to get some help with this, thanks

Hi 
 You should be able to reach much longer distances if you use the Coded PHY (long range mode) instead of the 1M PHY, but please note that the data rate will be ~8 times lower, and that a lot of phones still don't support Coded PHY. 
 Please check out our test of the Coded PHY conducted by one of my colleagues here . Using a Development Kit you should be able to reach ~1300 meters in Coded PHY mode at 0dBm. We have not tested this at 8dBm ourselves, but it is described how to do so. 
 Best regards, 
 Simon
