Arista C-400 Wi-Fi 7 Access Point

The Arista C-400 is a mid-tier Wi-Fi 7 (IEEE 802.11be) access point engineered to bring multi-link operation and 6 GHz spectrum access to branch offices, retail environments, and distributed enterprise campuses without the overhead of flagship-class hardware. Built on a 2×2:2 tri-band radio architecture spanning 2.4 GHz, 5 GHz, and 6 GHz bands, the C-400 supports 320 MHz channel widths in the 6 GHz band and delivers aggregate theoretical throughput exceeding 6 Gbps. The platform integrates Arista's CloudVision cognitive management plane, enabling AI-driven channel selection, client steering, and real-time RF health monitoring that adapts dynamically to changing airtime demands in dense branch scenarios.

At its architectural core, the C-400 leverages Multi-Link Operation (MLO) to allow client devices to simultaneously transmit and receive across multiple frequency bands, reducing latency and improving reliability for latency-sensitive applications such as unified communications, video conferencing, and cloud-hosted ERP systems. The access point supports up to 4096 QAM modulation, Preamble Puncturing, and Target Wake Time (TWT), which collectively extend effective range, improve spectral efficiency, and reduce power consumption for IoT and mobile endpoint fleets. A dedicated scanning radio continuously monitors the RF environment for rogue APs, interference sources, and security anomalies without impacting client-serving capacity.

Deployment flexibility is a defining characteristic of the C-400. The unit supports both cloud-managed operation via Arista CloudVision and on-premises controller-based management through Arista's Wi-Fi management software, making it suitable for organizations with strict data-sovereignty requirements or limited internet egress at branch sites. A single 2.5 GbE uplink with IEEE 802.3bt PoE++ support simplifies cabling infrastructure, while a secondary 1 GbE port enables daisy-chain or local-switch connectivity. The C-400 launched in Q4 2025 as part of Arista's expanding Wi-Fi 7 portfolio, filling the mid-market gap between entry-level indoor APs and high-density stadium-class units.

Ideal for

• Branch office connectivity for distributed enterprises requiring 6 GHz coverage without high-density AP capital expenditure
• Retail store networks serving point-of-sale terminals, digital signage, and customer guest Wi-Fi simultaneously across segmented SSIDs
• Healthcare clinic environments needing reliable, low-latency wireless for electronic health record access and VoIP-over-Wi-Fi handsets
• Educational institution classrooms and libraries where MLO reduces per-student latency during concurrent video streaming and cloud application sessions
• IoT gateway deployments leveraging TWT scheduling to extend battery life across large fleets of sensors, scanners, and smart-building endpoints
• Hospitality and hotel floor coverage where the C-400's cognitive steering maximizes per-room throughput across overlapping 2.4/5/6 GHz cells
