Testing and Conclusions

I will be testing the data transfer speed of the Cirago Bluetooth Adapter by transferring data from my desktop to my laptop. The specs of my desktop system are listed below, along with the specs of the laptop.

Desktop

AMD Athlon 64 X2 3800+
Zalman Heatsink
2 GB OCZ Platinum PC-4000 EB DDR
DFI LanParty UT Nforce4 SLI-D
XFX 7300GT
Two Seagate 400 GB 7,200 RPM SATA 3.0 Drives in RAID 0
Western Digital 74 GB Raptor 10,000 RPM SATA
780w OCZ ModXStream PSU
Creative X-Fi Sound card
Hauppauge TV Tuner
Mountain Mods Duality Case

Laptop

AMD Turion 64 X2 @ 1.8 Ghz
2 GB RAM
12" Convertible Screen
160 GB HDD

I will be transferring a 4 MB MP3 file from the desktop to the laptop under four different scenarios. First, I will conduct this test with the laptop sitting right beside the desktop, about 1 foot away. Next, I will move the laptop to the other side of my desk and repeat the test, about 4 feet away. Then, I will run this test with the laptop on the corner of my bed, which is about 7 feet away from the desktop. Finally, I will repeat the last test, but this time, I will be sitting at my computer desk, which is in the direct line-of-sight between the desktop and laptop. Each test will be run three times, and I will average the results together to get the final data transfer speed.



Setting up a data transfer is very easy. Simply right click on the file or folder you want to transfer, then mouse down to "to Bluetooth" and click the device you want to send your file(s) to. Below are the results from my testing.



I also tested the adapter by sending pictures and other random files, but the data transfer rate didn't change so there is no real need for further charts. What we see here is about what I expected. Bluetooth is a line-of-sight technology, so when I was sitting at my computer (interrupting the line-of-sight), transfer times slowed drastically.

Conclusion

The Cirago Micro USB Bluetooth Adapter worked as advertised in our testing. The adapter is very small, so it will not take up a lot of space. But, this small size does come with a potential drawback - it could easily be misplaced/lost. Installation was very easy and only took just a few minutes to complete. The adapter software was also easy to work with and had no problem detecting the other adapter as well as my iPhone. Data transfer speeds were as anticipated. One cool thing to note is that you can have multiple active connections simultaneously, should you have more than one Bluetooth-compatible device.

If you are in the need for a very small Bluetooth Adapter, I would definitely give the Cirago Micro USB Bluetooth Adapter a serious look. As of writing, this adapter sells for $24.99.
