28m of range this is much better than 6m, but we lost the router ;D ;D 8)
ORICO BTA-408 Bluetooth 4.0 dongle while I selected it due it quality of chip BCM20702, speaking of range this is a huge disappointment.
Out of the box this does only six meters ... What ? YES
ORICO engineers did something terrible speaking of PCB antenna design and performance speaking of range in meters this is terrible to unacceptable.
Bluetooth & WiFi antennas both working at about 2,4GHz and therefore due identical wavelength they are able to serve in both applications.
Instead spending money to hack my Bluetooth dongle, I did use old items that I am keeping for spare parts.
New dongle case this is from old USB to IR dongle ( old days of Windows 98).
The Antenna came from my old Thomson TG587 ( Equipment which I was using five years back with old internet provider.)
In conclusion
New performance limits they are fantastic 8)
a) 10 meters ( within walls )
b) 20 meters line of sight (warrantied pairing)
c) 28 meters line of sight ( Stable link by standing at side walk of next square from my office )
dBi Gain of Thomson TG587 Antenna this is 3.01 dBi at 2472 MHz, and it did miracles in my case. ;)
Length this is approximately 9 centimeters.
Enjoy the pictures !! :)
