A lot of the recent buzz around femtos has headed West across the Atlantic in recent months.
Sprint is continuining to roll out Airave, Verizon has been talking about launching its own 2G CDMA femto, and even AT&T has come out and said it's quite keen on the possibilities. And T-Mobile, while better-known for its dual-mode UMA service based on WiFi, has in fact been one of the pioneers in deploying femtos' bigger brothers, picocells.
Against that backdrop, the upcoming Avren conference in Dallas next month should be pretty lively. Details are here - tell 'em I sent ya.
