Cradlepoint TAA-MBA1-2155-5GB-GA 4-Port 2.5G Switch
Overview
The Cradlepoint TAA-MBA1-2155-5GB-GA is a 4-port 2.5 Gigabit Ethernet switching module designed for integration into Cradlepoint mobile router and wireless gateway platforms. This module addresses the specific problem of local edge switching in distributed deployments where cellular or WWAN backhaul is the primary link—remote construction sites, temporary event security, mobile command posts, and field surveillance operations where you need to aggregate multiple IP camera streams or networked devices before data traverses a bandwidth-constrained cellular connection. The TAA-MBA1-2155-5GB-GA operates as a captive modem-mode adapter, delivering 2.5G switching capacity at the edge without introducing a separate power supply or management layer.
Compatibility
This switch module is designed specifically for Cradlepoint R2155 mobile computing platforms and related Cradlepoint WWAN and cellular gateway chassis. It integrates into Cradlepoint's distributed routing ecosystems and operates as an internal switching component—not a standalone switch. Verify your existing Cradlepoint router model supports this module before ordering. The TAA-MBA1-2155-5GB-GA is compatible with enterprise and mobile network deployments where TAA compliance requirements are mandatory.
Deployment Considerations
The 2.5G per-port capacity handles multiple 4MP and 5MP IP camera streams without creating a local switching bottleneck, but upstream bandwidth (your cellular or WWAN pipe) is the real constraint in edge surveillance scenarios. Calculate total camera bitrate against your WAN throughput before deployment—the switch won't be your limitation, but your carrier connection very well might be. This module is not field-swappable; it requires integration during Cradlepoint platform configuration. Confirm module compatibility with your specific R2155 firmware version and chassis revision before procurement.
