We get the feeling that early 2010 is going to be big for Sprint’s WiMax. We came by one of these training slides for a new 3G/4G mobile hotspot, precisely like the Mi-Fi, for Sprint. Like many of Sprint’s wireless data cards, this one is also going to be made by Sierra Wireless. What we’re hearing is that this new device will be able to support up to five users via Wi-Fi and its range is being increased to 100 feet. In addition to the added range and power, it will also support SD card storage; while that doesn’t sound like a big deal, the data can be shared by every user who is connected to the data card. No official pricing or release date just yet, but we’re looking at a possibly February launch for this dual 3G-4G wireless hotspot in your pocket.
