For a small team sending photographs or finished work from the road, the useful modem number is the one attached to sending. Qualcomm’s February 21, 2017 X20 announcement specified downloads up to 1.2 Gbps, but uploads up to 150 Mbps. That distinction should shape an equipment discussion: receiving a large file and delivering one to a client are different tasks. [x20]
The older comparison makes the point concrete. In its February 11, 2016 X16 announcement, Qualcomm specified downloads up to 1 Gbps and uploads up to 150 Mbps. The advertised upload ceiling therefore stays the same across these releases even though the download ceiling changes. Neither announcement supplies a measured result for a worker’s phone, route or file transfer. [x16][x20]
Our recommendation is to describe the upload problem before choosing replacement equipment. Pick a representative file and record whether the concern is time to finish sending, interrupted transfers or simply receiving reference material. Ask a prospective supplier for an upload demonstration matched to that task. A download demonstration answers the receiving question; it should not silently stand in for evidence about sending. [x20][x16]
Keep the resulting decision note short: the job to be done, the direction of transfer, the observed result and the unresolved question. Equal advertised uplink limits do not prove equal real performance, so this comparison neither endorses nor rules out an upgrade. It identifies the evidence a team should request before spending money to solve an upload problem. [x16][x20]
