Cisco acquired a cellular GSM femtocell/picocell startup company named Jetcell, and a cellular CDMA femtocell/picocell startup company named Exio almost 8 years ago. Both of these companies had working femtocell/picocell products. Cisco briefly marketed the GSM product acquired from Jetcell as part of a Cisco MNET concept, the product nomenclature was known as 'GP10' which connected with standard GSM cellphones. The CDMA product acquired from Exio never made it into the market. Shortly after the acquisition of both these companies the dot com bust occured and these products were shelved probably never to return. I imagine all the cellular engineering expertise Cisco acquired from these two companies have moved on.
