David Pogue writes about three of the increasingly large number of cellular data to Wi-Fi gateways: He praises the notion of pairing the ubiquitousness of 2.5G and 3G cell data networks in the US with the affordability and utility of Wi-Fi adapters found in every device. He notes how a mobile router that combines WWAN and WLAN (and Ethernet LAN in Junxion and Top Global's boxes) is ideal for traveling workgroups. The Kyocera gateway works with just Verizon and Sprint's cards; the other two handle a wide range.
Pogue notes that despite protestations from companies like Verizon over the inadvisability of violating one's terms of service by sharing a 3G connection, it's inevitable that this kind of sharing will simply be part of the contract. He writes a propos of DSL and cable firms wanting to charge per computer on a home broadband network, "In the end, of course, common sense won, the cable companies lost, and now just about every home D.S.L. or cable modem signal is shared among two or more computers."
