It is official: Sierra Wireless will cease production of the AirLink GX440 in that not too distant future. The Sierra Wireless GX440 is sunsetting at the end of 2015. Last buy for the GX440 will be Dec. 31st, 2015. Last shipment will be June 30, 2016. Why the six month differential between last buy and last shipment? Because Sierra Wireless is most likely going to allow phased purchase orders is our interpretation. The replacement product for the GX440 is the GX450. The time to start planning for your company’s migration to the GX450 is now. For a summary description of the differences between the GX440 and the GX450, visit this link.
