A New Era of Wireless Performance:
For more than two decades, Wi-Fi innovation has driven digital transformation across every industry. From the 11 Mbps speeds of 1999’s 802.11b to today’s multi-gigabit Wi-Fi 7 networks, wireless has evolved from convenience to critical infrastructure.
Now, with Wi-Fi 7 (802.11be), we’re entering a new era of deterministic, low-latency, AI-ready wireless networking built for next-generation workloads like IoT, automation, and real-time collaboration.
Wi-Fi 7 Technical Advancements:
Feature | Wi-Fi 6E | Wi-Fi 7 |
Maximum Data Rate | 9.6 Gbps | 23 Gbps |
Channel Width | 160 MHz | 320 MHz |
Modulation | 1024-QAM | 4096-QAM |
Multi-Link Operation (MLO) | — | ✅ |
Restricted Target Wake Time (R-TWT) | — | ✅ |
Bands Supported | 2.4 GHz / 5 GHz / 6 GHz | Simultaneous 2.4 / 5 / 6 GHz |
Wi-Fi 7 triples potential throughput over Wi-Fi 6 through Multi-Link Operation (MLO), which aggregates multiple bands for concurrent data transmission.This design delivers both higher speeds and sub-10 ms latency, critical for AR/VR, robotics, and time-sensitive control systems.
Combined with 4096-QAM and 320 MHz channels, Wi-Fi 7 enables true multi-gigabit wireless access across the enterprise edge.
Spectrum Expansion
2.4 GHz: 60 MHz total (3 × 20 MHz channels)
5 GHz: 500 MHz total (25 × 20 MHz channels)
6 GHz: 1,200 MHz total (59 × 20 MHz or 3 × 320 MHz channels)
The 6 GHz spectrum represents the largest expansion in Wi-Fi history, providing ample bandwidth for dense environments and AI-driven workloads.

Range up to 200 ft / 60 m line-of-sight
Convertible indoor/outdoor deployment kit
Selectable narrow or wide beam coverage
Built for stadiums, campuses, and large venues requiring long-range, high-capacity coverage.
Infrastructure Readiness
Next-gen tri-band APs demand more power and bandwidth:
Expect > 30 W PoE under full load.
Use UPOE and Multi-Gig (2.5 G / 5 G) switches to avoid bottlenecks.
Verify PoE++ or UPOE+ to enable full AP functionality.
Throughput and MLO performance depend directly on your wired edge capacity.
Ultra-Reliable Wireless Backhaul (URWB)
Cisco URWB delivers fiber-class performance over unlicensed spectrum, offering:
< 10 ms latency
Zero packet loss with seamless handoff
Mobility for moving assets and remote sites
URWB and Wi-Fi can operate simultaneously on the same AP, simplifying management and extending connectivity to hard-to-reach areas.
Use cases: industrial automation, transport, logistics, and smart cities.
Ultra-Wideband (UWB): Sub-Meter Precision
Embedded UWB in the CW9176 and CW9178 provides < 1 m accuracy and superior efficiency compared to BLE.
Applications include:
Healthcare: asset tracking, patient wayfinding, fall detection
Retail: aisle-level analytics, proximity marketing
Enterprise Safety: staff location and emergency alerts
Controller Integration: Cisco Catalyst CW9800 Family
The CW9800 controllers (M, H1, H2) deliver unified management across Wi-Fi 6/6E/7 and URWB, supporting on-prem, private cloud, and hybrid deployments.
Key benefits:
Consistent security and policy enforcement
AI-driven assurance and analytics
Scalable software-defined wireless fabric
Future-Proofing the Enterprise Edge
Wi-Fi 7 is a critical inflection point — shifting from adaptive wireless to deterministic, AI-optimized connectivity.
