2.4Ghz should have been divied up in the first place!
JimT@Future-Product-Innovations   7/16/2013 1:29:04 PM
The article mentions that all 3 protocols share the IEEE 802 standard;  but more specifically, all 3 were developed  to operate within the same frequency bandwidth, being  2.4GHz.  

To clarify, the 802 standard is very lengthy, and comprises ANY technology using ANY wireless frequency that relates to "network protocols", which is a pretty broad topic!  (for an indexed  summary of 802.xx, see a nice Wikipedia chart at  http://en.wikipedia.org/wiki/IEEE_802  )

But all 3 of these short range protocols were conceived to operate in only one bandwidth, being 2.4GHz. What's most amazing is, so does your kitchen's microwave oven; which is NOT listed anywhere in 802 standard.

I remember when I first began reading these standards nearly 10 years ago, as the IEEE was defining and refining them, I asked some very smart people, "won't these multiple protocols begin stepping all over each other as they become more and more commonplace in the future-?"

(In my simple little brain, the standards should never have shared the bandwidth as a foundation)

The real answer was left to individual developers (at the time, huge corporate entities like Motorola and Nokia) to create co-existence algorithms to reside simultaneously within the custom transmissions.

Today, because of the countless tiny OEMs who are actively playing in this booming market, the cautions have been overlooked, and the original vision of the IEEE has been compromised.

Accordingly, GapSense is going to be a useful thing.

Personally, i am excited to know about GapSense as it has tackled one of the toughest problem in wireless coexistence. I am at present working on a similar challenge or wireless coexistence too. This will solve many issues in modern world like using wireless or mobile phone in aircraft, using wireless in critical applicati. ons like healthcare.

GapSense will surely revolutionise wireless communication by eliminating wireless coexistence ( intentional sources). please find the research paper on GapSense here: http://kabru.eecs.umich.edu/papers/publications/2013/xyzhang_kgshin_infocom13.pdf

Wireless coexistence is a major hurdle in the wireless scenario with WiFi, Bluetooth and ZigBee devices in close proximity. GapSense will solve this issue to a great extent. This will be an answer to the coexistence issue. This is an important article.
