ABI Research predicts UWB will get uptake: The analysis firm believes that "formidable-looking barriers" will be overcome for "widespread commercial success" with UWB. Neither the collapse of a single standards effort nor the emergence of 802.11n will cause UWB to falter, they say, and the Bluetooth SIG's support should help. Global spectrum and regulatory approval, cost, power consumption, and silicon package sizes are "legitimate concerns" they note. The firm believes that 7 GHz to 8.5 GHz--a very small chunk for UWB's needs--will be sections approved across many regulatory regions with Europe supporting 6 GHz to 8.5 GHz and Japan probably ratifying 7 GHz to 10 GHz.
