The HP 4G LTE-Advanced Pro Cat16 WWAN module (B8BD2AA) is an internal M.2 mobile broadband card that adds built-in 4G connectivity to selected HP business notebooks, so users can get online over a cellular network without a USB dongle or phone hotspot. HP lists it for the EliteBook 6 G1i (13, 14 and 16 inch), EliteBook 6 G1a (14 and 16 inch), EliteBook 6 G1iR, and ProBook 4 G1i and G1a (14 and 16 inch) models. LTE Category 16 is designed for gigabit-class download speeds where the network supports carrier aggregation, and the module uses 256-QAM modulation. It is aimed at field staff, sales teams and travellers who need connectivity away from Wi-Fi. The card measures 52 x 30 x 2.3 mm and weighs about 7 g, and it supports Windows 10 and 11. Installation is internal, and a matching notebook with WWAN antennas is required.
