![]() ![]() That said, the 250U has several advantages over the earlier modem. I'd expect similar performance in large part because the two modems use the same chipsets-Qualcomm's QSC6085 on the 3G side and Beceem's 250 on the 4G side. ![]() The 250U was faster on one category of 4G downloads, but I wouldn't draw broad conclusions from that. I compared the 250U to Sprint's earlier U301 modem in 3G mode in New York City and in both 3G and 4G mode in Philadelphia. In a stone building in Philadelphia, I could still get strong (-65 to -70 dBm) 4G signal on the dedicated modems while my 4G phones wavered in and out of 4G coverage. But there's also something to be said for spreading your battery-draining uses over several devices, and the modems tend to get much stronger 4G signal than the phones. With the Samsung Epic 4G ($199.99, ) and HTC EVO 4G ($299.99, ) offering wireless hotspot modes and tethered modem capabilities, you have to ask: why get a modem anyway? Road warriors know one answer, of course many businesses will pay for data contracts for their mobile workforces but don't want to buy everyone phones.
