Cradlepoint TAA-MA3-1700120B-NNA vs Cradlepoint MB03-2155-5GB-GA: Specification Comparison
Both the Cradlepoint TAA-MA3-1700120B-NNA and MB03-2155-5GB-GA are managed 4-port Ethernet switches from the same manufacturer, positioned for enterprise and field network deployments. The comparison centers on port speed tier, compliance posture, operating environment, bundled management, and physical form factor — the dimensions that most directly drive purchase decisions for IT buyers choosing between a ruggedized mobile-edge switch and a high-throughput fixed-site 10G switch.

Which switch delivers higher port speed and throughput for your traffic demands?
The TAA-MA3-1700120B-NNA provides 5 GbE ports (LAN/WAN switchable), giving installers flexibility to designate uplink or downlink roles per port. Its specified firewall throughput is 940 Mbps. Port speed is Gigabit (1 GbE) across all five interfaces.
The MB03-2155-5GB-GA offers 4 ports at 10G speed — a full 10× step up per port over Gigabit. No firewall throughput figure is provided in the available specs. The LAN/WAN-switchable feature is not listed for this model; its operating mode is noted as 'Captive modem.'
For deployments aggregating high-bitrate sources — multi-camera 4K streams, high-density Wi-Fi APs, or server uplinks — the MB03-2155-5GB-GA's 10G port speed is a material advantage. For mobile and field sites where 1 GbE is sufficient and an additional fifth port adds flexibility, the TAA-MA3-1700120B-NNA's 5-port, LAN/WAN-switchable layout holds practical value.
Which switch is better suited to harsh operating environments and government procurement requirements?
The TAA-MA3-1700120B-NNA carries an operating temperature rating of -30°C to 70°C (-22°F to 158°F), making it suitable for uncontrolled or outdoor-adjacent environments. It holds TAA (Trade Agreements Act) compliance plus PTCRB, GCF, AT&T, Verizon, and FirstNet Trusted certifications — qualifications directly relevant to public-safety and government cellular network deployments.
The MB03-2155-5GB-GA has no operating temperature range specified in the provided data. Its physical dimensions are documented at 17.63 × 7.5 × 5.5 in and 5.03 lbs, suggesting a rackmount or desktop chassis intended for controlled indoor environments. No environmental certifications or TAA compliance status are listed for this model.
For government, defense, or first-responder procurement requiring TAA compliance, or for vehicle-mounted and outdoor-cabinet deployments demanding a verified thermal envelope, the TAA-MA3-1700120B-NNA has documented credentials. The MB03-2155-5GB-GA's environmental and compliance posture cannot be assessed from the available specs.
How does each switch's management platform and included software affect total cost of ownership?
The TAA-MA3-1700120B-NNA is described as a managed switch; the management platform name is not specified in the provided specs beyond 'Managed: Yes.' Its certifications reference operating modes including dual-modem, 5G-enabled, and private cellular (CBRS, 4G LTE), indicating integration within Cradlepoint's broader cellular-edge ecosystem.
The MB03-2155-5GB-GA explicitly bundles a 3-year NetCloud management subscription, as stated in both the product name and Card Bullet 1. NetCloud is Cradlepoint's cloud management platform. This bundling means the total acquisition price includes three years of management licensing — relevant to TCO calculations when comparing against separately licensed alternatives.
Buyers evaluating management overhead should note that the MB03-2155-5GB-GA's NetCloud bundle provides immediate, documented cloud management for 36 months. The TAA-MA3-1700120B-NNA's management tier and any associated subscription terms are not specified in the available data and would need to be confirmed with the vendor before procurement.
Which should you choose: the TAA-MA3-1700120B-NNA or the MB03-2155-5GB-GA?
Our take: The TAA-MA3-1700120B-NNA is the stronger choice when the deployment demands TAA-compliant, ruggedized switching in mobile, vehicle-mounted, or field environments with cellular uplink integration. Its -30°C to 70°C operating range, FirstNet Trusted and PTCRB certifications, and 5-port LAN/WAN-switchable design are purpose-built for public-safety and distributed-edge use cases that the MB03-2155-5GB-GA cannot be confirmed to match, as no operating temperature or compliance certifications are provided for that model. Conversely, the MB03-2155-5GB-GA's 10G port speed is a 10× step up over the TAA model's 1 GbE, and its bundled 3-year NetCloud subscription is an explicitly documented inclusion that simplifies TCO for fixed-site, high-throughput indoor deployments. Buyers should confirm the TAA-MA3-1700120B-NNA's management subscription terms separately, as they are not specified.

Frequently Asked Questions
Which should you choose: the TAA-MA3-1700120B-NNA or the MB03-2155-5GB-GA?
The TAA-MA3-1700120B-NNA is the stronger choice when the deployment demands TAA-compliant, ruggedized switching in mobile, vehicle-mounted, or field environments with cellular uplink integration. Its -30°C to 70°C operating range, FirstNet Trusted and PTCRB certifications, and 5-port LAN/WAN-switchable design are purpose-built for public-safety and distributed-edge use cases that the MB03-2155-5GB-GA cannot be confirmed to match, as no operating temperature or compliance certifications are provided for that model. Conversely, the MB03-2155-5GB-GA's 10G port speed is a 10× step up over the TAA model's 1 GbE, and its bundled 3-year NetCloud subscription is an explicitly documented inclusion that simplifies TCO for fixed-site, high-throughput indoor deployments. Buyers should confirm the TAA-MA3-1700120B-NNA's management subscription terms separately, as they are not specified.
Is the TAA-MA3-1700120B-NNA or MB03-2155-5GB-GA better for government or public-safety procurement?
The TAA-MA3-1700120B-NNA is documented as TAA-compliant and holds FirstNet Trusted, PTCRB, GCF, AT&T, and Verizon certifications — credentials directly required for many government and public-safety contracts. The MB03-2155-5GB-GA has no TAA compliance or equivalent certifications listed in the available specifications, so it cannot be confirmed suitable for TAA-mandated procurement.
Which switch handles faster traffic — the TAA-MA3-1700120B-NNA or MB03-2155-5GB-GA?
The MB03-2155-5GB-GA operates at 10G per port, versus the TAA-MA3-1700120B-NNA's Gigabit (1 GbE) per port. For high-bitrate applications such as multi-stream 4K video aggregation or dense access-layer uplinks, the MB03-2155-5GB-GA's 10G port speed is significantly higher. The TAA model specifies 940 Mbps firewall throughput; no equivalent throughput figure is provided for the MB03 model.
Does the MB03-2155-5GB-GA include management software, and does the TAA-MA3-1700120B-NNA?
The MB03-2155-5GB-GA explicitly bundles a 3-year NetCloud management subscription as part of the product package. The TAA-MA3-1700120B-NNA is listed as 'Managed: Yes' but the specific management platform name and any subscription terms are not detailed in the available specifications — those details should be confirmed with Cradlepoint or the reseller before purchase.
