Cradlepoint TAA-MBA5-2155-5GB-GA R2155 Desktop 5G WWAN Router
Overview
The Cradlepoint TAA-MBA5-2155-5GB-GA R2155 is a desktop WWAN router engineered for branch offices, edge network locations, and mobile command centers that require bulletproof WAN failover. It supports 3G, 4G, and 5G cellular connectivity alongside wired Ethernet, so if your primary circuit fails, traffic automatically routes through available mobile networks without manual intervention. The 5-year TAA (Trade Agreements Act) compliance certificate comes standard, making this a federal procurement-ready choice for integrators and MSPs deploying across government and commercial infrastructure. This is not a consumer device — it's built for unplanned outages and mission-critical uptime.
Key Features
- 2.5 Gigabit Ethernet: Data link speed supports 2.5G Ethernet, which is 2.5× faster than standard 1G Gigabit connections. This matters when you're concentrating traffic from multiple sites through a single WAN uplink — you avoid bottlenecks on file transfers, backup traffic, or video surveillance feeds. Ideal for branch sites feeding data to a central data center or cloud environment.
- Dual-WAN Failover (3G/4G/5G Cellular): The device bonds and failover between fixed-line Ethernet and any available cellular standard. If your broadband goes down at 2 a.m., the router automatically shifts traffic to 4G or 5G without user intervention. No dropped VoIP calls, no interrupted RDP sessions — continuity is automatic. This is the primary reason integrators choose a WWAN router instead of a basic edge switch.
- Desktop Form Factor: Compact enough to sit on a shelf or desk, not a rack mount. This keeps installation simple in small branch locations, field offices, or temporary command centers where rack space doesn't exist. Standard Ethernet connectors on the back; plug into your existing network infrastructure and carrier SIM slot.
- TAA Compliance (5-Year Coverage): The TAA certification is pre-installed — no additional paperwork, no third-party audits required. If you're a federal integrator or working with government contracts, this product clears Section 889 procurement restrictions immediately. Saves weeks of compliance documentation.
- MSP-Friendly Management: Built for remote provisioning and multi-site oversight. Managed service providers can deploy multiple R2155 units across distributed locations and centrally manage bandwidth policies, failover rules, and health monitoring from a single pane of glass. Reduces on-site truck rolls and accelerates incident response.
- Edge Network Deployment: Position this at branch offices, warehouse sites, or retail locations where you need redundancy but don't have the budget or footprint for a full SD-WAN appliance. It sits between your access layer and WAN circuits, creating a simple but effective failover mesh.
Integration & Compatibility
The R2155 integrates with standard Ethernet infrastructure — plug it into your existing switch, configure IP routes and failover policies, and pair it with your carrier's SIM. Compatible with 3G, 4G, and 5G networks from major carriers (Verizon, AT&T, T-Mobile, and others). Supports both domestic and roaming scenarios. When deployed in a network edge environment, it acts as a transparent failover device, requiring no changes to downstream devices or applications.
When to Choose a Different Model
If you need rack-mounted or high-density multi-WAN consolidation across dozens of branch sites, consider larger models in the Cradlepoint family that offer more cellular slots or integrated switching. If your deployment is stationary and carriers guarantee SLA, a standard Ethernet-only switch may be sufficient — the R2155 adds cost for redundancy you may not need. If you require 10G Ethernet speeds for data center aggregation, this device's 2.5G ceiling may limit throughput.
Frequently Asked Questions
Q: Is the TAA-MBA5-2155-5GB-GA compliant with federal procurement rules?
A: Yes. The 5-year TAA compliance certificate is included. The device meets Buy American Act requirements and Section 889 restrictions, making it eligible for federal contracts without additional certification steps.
Q: What happens if both Ethernet and 5G fail?
A: The device has no built-in tertiary failover. If both primary circuits are down, traffic cannot route. This is why integrators often deploy two R2155 units at critical sites, bonded in redundant pairs.
Q: Can I manage multiple R2155 units from one dashboard?
A: Yes. The device supports centralized MSP management. You provision and monitor multiple routers remotely, configure bandwidth rules, and troubleshoot failover events from a web console or management platform.
Q: Does the R2155 require a carrier contract?
A: Yes. Cellular connectivity depends on a SIM card and active carrier plan (Verizon, AT&T, T-Mobile, etc.). The router itself is carrier-agnostic, but you must provision the circuit separately.
Q: What's the power requirement?
A: Refer to the manufacturer datasheet for exact power specifications. Desktop deployments typically use standard AC wall adapters or 12VDC supplies; confirm with the product documentation for your specific environment.
Q: Can this router replace a firewall or SD-WAN appliance?
A: No. The R2155 is a failover and WAN aggregation device, not a security gateway. It should sit behind your primary firewall or security appliance. For enterprise SD-WAN with advanced security, larger Cradlepoint models or dedicated SD-WAN platforms are required.

The Cradlepoint TAA-MBA5-2155-5GB-GA excels at one specific job: transparent WAN failover for branch and edge deployments. The 2.5 Gigabit Ethernet interface is the right speed for consolidating traffic from smaller locations without introducing a bottleneck — you're not paying for 10G when 2.5G is genuinely sufficient. What clinches this device for government integrators is the 5-year TAA compliance baked in; you skip the certification gauntlet entirely.
Technical Highlights:
- 2.5G Ethernet uplink: Provides 2.5× the bandwidth of standard 1G Gigabit without forcing you into expensive 10G infrastructure. For typical branch-to-HQ traffic patterns (file sync, backups, video surveillance feeds), this speed ceiling rarely matters in real deployments — but when it does, you're not constrained by a 1G wall.
- Automatic 3G/4G/5G failover: The router continuously monitors Ethernet circuit health and shifts traffic to cellular without user intervention. Mean time to failover is measured in seconds, not minutes. This is critical for mission-essential sites where downtime costs more than the cellular backup SIM.
- TAA pre-certification (5-year coverage): Eliminates a multi-week compliance approval cycle. If you're bidding a federal contract, this device's compliance status is already audit-ready — no third-party validation, no additional paperwork.
Deployment Considerations:
- Single point of failure if both WAN paths drop simultaneously. For critical sites, deploy pairs of R2155 units in active-passive or active-active configuration to guarantee redundancy of redundancy.
- Cellular failover assumes carrier coverage at the deployment site. In rural or underground locations, 4G/5G signal may be spotty — verify coverage before committing to this architecture.
- The device is a layer-2/layer-3 failover appliance, not a security gateway. Stack it behind your existing firewall; don't expect integrated threat prevention or intrusion detection from the R2155 itself.
This is the right choice for integrators deploying redundant WAN at 50–200 branch locations that need plug-and-forget failover and federal procurement compliance. If your sites are stable-power environments with guaranteed carrier SIM provisioning, and you already have perimeter security in place, the R2155 slides into your network quickly and doesn't require constant tuning.
