Sophos AP 55C 802.11ac Dual Band Wireless Access Point | Wty
The Sophos AP 55C is a professionally restored enterprise-grade ceiling-mount wireless access point featuring 802.11ac Wave 1 technology with dual-band operation delivering 867 Mbps on 5GHz and 300 Mbps on 2.4GHz across two radios with 2x2 MIMO capabilities. Released in 2015, this access point provides reliable connectivity for small to medium-sized business environments—ideal when you need professional wireless infrastructure without enterprise pricing, because its dual-radio design handles up to 8 SSIDs per radio (16 total), which means you can segment your network for staff, guests, and IoT devices on a single access point. The ceiling-mount design includes four internal antennas with antenna gains of 4.36/5.77 dBi at 2.4GHz and 6.13/6.27 dBi at 5GHz, providing effective coverage across typical office spaces. Ideal For
This access point suits specific business scenarios:
- Small office environments (10-30 users) - Running email, web browsing, cloud applications, and VoIP calls simultaneously within a 15-20 metre radius from the ceiling-mounted unit
- Retail locations with guest Wi-Fi - Separate SSIDs for point-of-sale systems, staff devices, and customer internet access, keeping networks isolated for security compliance
- Educational spaces and training rooms - Classrooms or conference rooms with 20-40 concurrent wireless devices including laptops, tablets, and smartphones for presentations and collaborative work
- Existing Sophos UTM deployments - Organisations already managing Sophos UTM firewalls who want centralised wireless management without separate controller hardware Key Features & Benefits
- 802.11ac Wave 1 with 1.167 Gbps combined throughput: Real-world speeds typically reach 150-250 Mbps under normal office workloads—sufficient for video conferencing, cloud file transfers, and multiple simultaneous users without the premium pricing of newer Wi-Fi 6 hardware
- Dual-band, dual-radio operation: Operates 2.4GHz and 5GHz bands simultaneously with separate radios rather than switching between them, therefore legacy devices on 2.4GHz don't slow down your modern 5GHz clients
- PoE powered (IEEE 802.3at): Draws just 13W maximum through a single Gigabit Ethernet cable, eliminating the need for nearby power outlets in ceiling installations—particularly useful when mounting in hallways or open areas
- 16 total SSIDs supported: Eight SSIDs per radio allow extensive network segmentation for different departments, security zones, or guest access without additional hardware
- Professional ceiling-mount design: 200mm diameter white enclosure with plenum rating (UL2043 compliant) and included T-rail mounting hardware for drop-ceiling or solid-ceiling installation
- Centrally managed via Sophos UTM: Automatic firmware updates and configuration push from your existing Sophos UTM firewall (version 9.308 or later required)—no separate controller appliance or cloud subscription needed
- DFS and TPC support: Dynamic Frequency Selection and Transmit Power Control automatically adjust to avoid radar interference and comply with regulatory requirements across ETSI and FCC regions Common Questions Can the AP 55C handle a busy office with 25-30 users?
Yes, though performance depends on usage patterns. In our testing with similar Wave 1 access points, typical office workloads (email, web browsing, document editing, occasional video calls) work smoothly with 20-30 users per access point. However, if multiple users stream 4K video or perform large file transfers simultaneously, you may experience congestion—in high-bandwidth environments, consider multiple APs or spacing users across 2.4GHz and 5GHz bands. How does Wave 1 compare to newer Wi-Fi standards?
The 802.11ac Wave 1 standard (2013-2015 era) reaches theoretical speeds of 1.3 Gbps versus Wave 2's 2.34 Gbps or Wi-Fi 6's higher capacities. In practice, this 2015-era access point delivers 150-250 Mbps under real-world conditions—sufficient for standard business applications but not ideal for environments requiring simultaneous 4K streaming or heavy file server access across dozens of users. The advantage is significantly lower cost compared to current-generation hardware. Do I need a Sophos firewall to use this access point?
Yes, the AP 55C requires a Sophos UTM firewall running version 9.308 or later for configuration and management. The access point cannot operate standalone—it must be connected to and controlled by a Sophos UTM wireless controller. This centralized management approach simplifies deployment but means you need compatible Sophos infrastructure in place. Technical Specifications At a Glance
