Mobile Broadband Kits

Easy to use, environmentally robust, Internet Wi-Fi and wired hotspots for use globally using commercial 3G/4G/5G cellular and satellite communications technologies

Sub U Systems’ Mobile Broadband Kit (MBK) offerings support small, medium, and large teams of users who need Internet connectivity “wherever and whenever” they need access to voice, data, and video communications.

SUB-U MBKs offer VPN secured and unsecured Internet connectivity using public and private 3G, 4G, and 5G cellular (including Verizon Frontline, and FirstNet public safety access LTE cellular service) and satellite communications technologies. They also provide local area network connectivity using 802.11 Wi-Fi and Ethernet.

Our MBKs come in all shapes and sizes, battery technologies, and levels of technology sophistication. We have options based on several wireless router companies, including Cisco, Cradlepoint, Aruba, Juniper 128 Technologies, and SUB-U. Our MBKs are far and away the most reasonably priced in the market, presenting the best value to local, state, and federal government and military customers. Commercial companies and private individuals may also acquire our MBKs.

SUB-U believes that to produce the very best communications solutions you need to have access to the best technology. As a result of our over thirteen year history building deployable communications solutions, and our half dozen plus issued patents, SUB-U has established formal partnerships with Cisco, Cradlepoint, Inmarsat, Iridium, and many other commercial best of breed technology companies.

Additionally, SUB-U’s engineering resources are second to none. We employ Mechanical, Electrical, Software and Systems engineers with decades of experience to ensure that when we develop a commercial product integration solution it receives the same attention to detail as our PCB and firmware up product development efforts.

The MBK R1900M and PWC-IBR900 are the two latest additions to our MBK product family. The MBK R1900M is based on Cradlepoint’s new R1900 4G/5G wireless router and utilizes off the shelf military 2590 and/or PRC148/152 twist lock batteries paired with SUB-U’s battery charging/UPS logic that is widely used and field proven across many other products in the SUB-U product portfolio. Whereas, the PWC-IBR900 represents yet another “first of its kind” capably that SUB-U is renowned for, whereas SUB-U has integrated the Cradle IBR900 into a fully machined metal, extremely environmentally robust, “walkie talkie” style device for use with military style PRC148/152 twist lock batteries and person wearable radio pouches.

SUB-U takes great pride in listening to customers and developing products and solutions that meet and surpass their needs and requirements.
