Via Seattle PI/John Cook, Seattle’s Junxion has been acquired by Vancouver’s Sierra Wireless in an asset sale. This is the second recent instance of an American tech company being bought north of the border, after NowPublic acquired Truemors last month. Rumors earlier this year mentioned a figure $2M price but the final price is undisclosed. Junxion produces a line of distinctive-green-box, enterprise-grade cellular routers that power, among other things, wifi on Microsoft’s company commuter buses. This meshes well with Sierra’s various wireless offerings, though demand for cellular routers may be hampered by the rise of mostly-affordable 3G networking.
