Good evening all. I’m Jacob Eva, representing my company Liberated Embedded Systems Ltd.
We have been working on an LTE expansion card for quite some time now, and we’re excited to show some early renders of our module for your reference!
Top view.
Rear view.
This module will support 4G LTE speeds (no 5G, too expensive!) and has three connectors for antennas. The two larger connectors are SMA connectors, with the antenna on the left being the primary antenna, and the one on the right an optional diversity antenna. We also have a U.FL connector to allow for the connection of a GPS antenna (yes it works!) to the laptop. We have additionally included a nano SIM card holder on the bottom of the module to facilitate inserting a SIM card, so you can actually connect 
Might I also add, this will be open source hardware (design files will be released after completion), so no anti-consumer withholding schematics shenanigans
We expect to be performing some test trading of this module once we have put it to production, which should be within the next couple of months.
Therefore, for any of you who may be interested in purchasing our module, please email us at contact@liberatedsystems.co.uk to sign up for our newsletter (please also include your country of residence too so we know where our market will be!) so that we may notify you when it will be available to purchase 
That’s all for now, technology for freedom.
