IEEE 802.11 AND OUR TECHNOLOGY
Treat wireless LAN as one system spanning the physical layer, network, applications and power
Kei Communication Technology Inc. began by developing the network equipment and communications technologies required to meet demanding operational specifications.
Our in-house capabilities have been built around implementation rather than isolated product supply.
Our OUI 00:16:AA,
in-house SNMP protocol stack, remote monitoring, power-quality technologies and UPS capabilities
form a single technical lineage developed to keep networks operating continuously.
At the 2003 iEARN International Conference, we responded to a SARS-related venue change by implementing IEEE 802.11, FSO, Ethernet, IP, video streaming, remote participation, installation, monitoring and power as one integrated system within a short timeframe.
A modern wireless LAN also becomes a continuous service only when access points, PoE switches, VLANs, authentication, name resolution, backhaul, cloud services, monitoring, power and maintenance operate together.
STANDARD / CERTIFICATION / DEPLOYED SYSTEM
Distinguishing the IEEE 802.11 standard, Wi-Fi certification and deployed infrastructure
IEEE 802.11 is a family of standards centered on wireless LAN MAC and PHY and extending into management, measurement, security, mobility, sensing, low-power operation and related functions. Wi-Fi is a name and certification framework managed by the Wi-Fi Alliance to communicate product interoperability and feature sets to the market. In deployed infrastructure, products implementing the standard and certification are connected to backhaul, authentication, monitoring, power and maintenance systems.
IEEE 802.11
Technical specification
Defines MAC, PHY, management, security, measurement, mobility and related extensions.
WI-FI CERTIFICATION
Certification and market naming
Communicates interoperability, feature sets and generation names to users and the market.
DEPLOYED SYSTEM
Deployed infrastructure
The complete service, including APs, backhaul, authentication, applications, monitoring, power and maintenance.
Multiple functions work together between SSID visibility and usable business communications.
Observing device association, authentication, VLAN, DHCP, DNS, gateways, upstream links, cloud services and power as one service chain makes it possible to determine the communications state experienced by users.
END-TO-END IMPLEMENTATION / 2003
In 2003, we responded to a SARS-related venue change with an end-to-end implementation from the physical layer to video streaming
The 10th iEARN International Conference and 7th Youth Summit, held from July 21 to 25, 2003, brought together an international education network under rapidly changing conditions. During preparations, the social impact of SARS changed both the venue and the operating conditions. The communications paths, participation model and video-streaming environment had to be reconfigured quickly for the new venue arrangement centered on the Awaji Yumebutai International Conference Center.
We designed, installed and operated inter-building links using Free Space Optics (FSO), wireless access using IEEE 802.11, Ethernet and IP networking, video capture, encoding and distribution, internet videoconferencing, monitoring and power as one integrated system.
A public record published at the time by the Hyogo Prefectural education and training institute described this optical wireless deployment as Japan's first technical implementation. The system connected line-of-sight locations with optical beams without installing new fiber, creating high-speed backhaul for the venue's wireless LAN and worldwide video distribution.
The conference brought together approximately 1,000 participants from 55 countries, and all five days were streamed worldwide through the Hyogo Prefecture Educational Information Network. Students in Taiwan who were unable to travel because of SARS participated through internet videoconferencing.
Treating physical connectivity, wireless access, networking, servers, video streaming, installation, testing, monitoring and operations as one scope of responsibility enabled the rapid implementation under suddenly changed conditions.
Integrating IEEE 802.11 access with FSO optical wireless backhaul
FSO is an independent optical wireless technology that transmits and receives light through free space. In this deployment, IEEE 802.11 connected users and devices while FSO provided high-speed links between buildings, creating one communications infrastructure from access through backhaul to applications.
PHYSICAL
Physical links between buildings
FSO creates high-speed communications paths without road excavation or new fiber installation.
ACCESS
IEEE 802.11 wireless access
Connects conference participants, operations terminals and streaming equipment to the venue network.
NETWORK
Ethernet and IP
Connects wireless LAN, FSO, servers and upstream links to form communications paths within and beyond the venue.
APPLICATION
Video streaming and remote participation
Captures and encodes conference video for worldwide distribution and connects remote participants to the event.
OPERATIONS
Installation, testing and operations
Manages equipment selection, installation, optical alignment, configuration, testing, monitoring and incident response as one process.
Rapid reconstruction was enabled by an integrated design that did not divide the technology stack
We designed the system end to end, from the physical layer through the applications, and took responsibility for equipment selection, installation, configuration, testing and live operations. This allowed the entire communications infrastructure to be reconfigured quickly for the changed venue and operating conditions.
COMMUNICATION RESILIENCE
Reconfiguring communications paths and participation models: from 9/11 to SARS and COVID-19
The September 11, 2001 attacks in the United States, the 2003 SARS outbreak and the COVID-19 pandemic from 2020 onward were different types of social crisis. They nevertheless shared a common requirement: when existing communications links, venues and travel routes became difficult to use, new forms of connectivity had to be created quickly to maintain the flow of people and information.
2001 / SEPTEMBER 11
Supplementing damaged wired links with optical wireless
At court facilities in Lower Manhattan, FSO links between buildings were used to restore communications after existing infrastructure was damaged.
2003 / SARS
Reconfiguring infrastructure at a changed venue
We integrated FSO, IEEE 802.11, Ethernet, IP, video streaming and remote participation to implement the communications infrastructure for an international conference within a short timeframe.
2020 / COVID-19
Supporting activity without dependence on physical travel
Remote communications became essential for continuing education, conferences, healthcare and business operations, making infrastructure that connects people and information across locations a basic condition of social continuity.
OUR TECHNICAL CONTINUITY
Implementing wireless technology as the ability to reconfigure an entire communications infrastructure as conditions change
In 2003, we treated the physical layer, wireless access, networking, applications, installation and operations as one technical system and reconfigured the infrastructure in response to changes in both the social environment and the venue. That design philosophy continues in our current work in remote monitoring, power quality, UPS and distributed power systems.
END-TO-END WLAN OPERATIONS
Five operational layers that make up a wireless LAN service
Users interact directly with devices and access points, while the service itself depends on coordinated wireless access, backhaul, network services, power, monitoring and maintenance. Observing each layer on the same time axis allows quality changes and causes of service interruption to be isolated accurately.
Wireless access
The PHY and MAC between devices and access points, including management of the radio environment, channels, interference and mobility.
Access points
Connect the wireless segment to Ethernet and provide authentication, roaming and client access.
Backhaul
Ethernet, optical links, FSO and routers form communications paths within and beyond the site.
Network services
VLAN, DHCP, DNS, RADIUS, certificates and time synchronization support end-to-end communications.
Power, monitoring and maintenance
PoE, UPS, SNMP, logs and power data work together to support continuous infrastructure operations.
Items to verify in wireless access
- Radio interference, channel utilization, retransmissions and latency
- Quality variation caused by distance, obstacles, reflections and movement
- Association, roaming, authentication and client implementation
- Capacity relative to user counts and traffic volume
Items to verify in the upstream network and power system
- Status of PoE switches, PDUs, UPS systems and utility power
- VLAN, DHCP, DNS, RADIUS, certificates and time synchronization
- Ethernet, optical links, FSO, routers and VPNs
- Responses from cloud management, external authentication and applications
SNMP / ROOT CAUSE ANALYSIS
Observe radio, communications, equipment and power by layer to isolate root causes
We place data from our in-house SNMP protocol stack and MIBs, logs and power measurements on the same time axis, separating changes in wireless quality, device state, upstream communications and power conditions.
View our SNMP monitoring technology →WIRELESS NEEDS POWER
Protect access points, PoE switches and authentication infrastructure as one power system
Access points in enterprise, healthcare and public-sector facilities are commonly powered through Ethernet using PoE. Because a PoE switch concentrates both communications and power, APs, upstream switches, authentication and name-resolution services, and circuit termination equipment should be designed as one service power system.
| Asset to protect | Power dependency | Impact of interruption |
|---|---|---|
| Access point | PoE switch or AC adapter | The wireless cell disappears and connected devices are disconnected |
| PoE switch | Utility power, UPS and PDU | Multiple APs and upstream communications stop at the same time |
| Authentication, DHCP and DNS | Servers, virtualization platforms, cloud services and network links | Business communications fail even when a device appears connected |
| Circuit termination and routers | AC power, DC power and UPS | Off-site services, cloud access and VPN connectivity become unavailable |
PORTABLE UPS
Maintain communications equipment without interruption
Protect PoE switches, routers, servers and terminals from restart events.
View product (Japanese) →POWER QUALITY
Identify short voltage disturbances, including momentary interruptions and sags
Even a brief voltage drop can restart an AP or switch.
View explanation (Japanese) →PHASE-FREE POWER
Keep everyday power infrastructure available in emergencies
Support daily operations and emergency continuity with the same communications power infrastructure.
View strategy (Japanese) →OUI / MAC / PRIVACY
Device identity and privacy must be designed together
Wireless LAN devices use MAC addresses.
In a globally administered MAC address, the high-order bits contain an organizational identifier such as an OUI.
We manage our own OUI 00:16:AA as the identity foundation for our equipment.
MANAGED DEVICE IDENTITY
Continuously identify the same equipment in managed infrastructure
A managed identifier is required to connect a product with its installation site, monitoring target, maintenance history and replacement history. The OUI provides the foundation for managing an address space as the manufacturer.
View how we manage our OUI →CLIENT PRIVACY
Reduce tracking of user devices
Smartphones and PCs use randomized, locally administered MAC addresses. As a result, an observed MAC address alone may not establish the manufacturer or identify the same device over time.
Operate OUI-based identity together with certificates, serial numbers, installation data and monitoring history
IEEE 802.11bh addresses operational improvements for randomized and changing MAC addresses, while P802.11bi advances privacy protection further. For critical infrastructure, we use OUI and MAC addresses as identity anchors and combine them with serial numbers, certificates, installation information and monitoring history for asset management.
UHR / WI-FI 8 / SERVICE CONTINUITY
The next wireless LAN generation emphasizes connection continuity, low latency and high reliability alongside peak speed
P802.11bn Ultra High Reliability is also commonly referred to by the industry as Wi-Fi 8. In addition to peak speed, its direction is to improve overall wireless-service stability across latency, connection continuity, congested environments, mobility and multiple links.
Wireless quality
Manage interference, retransmissions, latency and device density.
Mobility
Reduce interruption and reauthentication during movement between APs.
Wired infrastructure
Maintain stable VLAN, QoS, authentication and upstream connectivity.
Power
Protect APs and switches from momentary interruptions and outages.
Connect high-reliability wireless standards to deployed infrastructure through Ethernet, PoE and UPS
Implementing IEEE 802.11 reliability in real infrastructure requires an integrated design incorporating IEEE 802.1 VLANs, authentication and management, IEEE 802.3 Ethernet and PoE, IEEE 802.19 wireless coexistence, and on-site UPS and power quality.
AI / MACHINE LEARNING / EDGE
AI not only optimizes wireless LANs; it also runs across them
Within IEEE 802.11, the AI/ML Standing Committee examines use cases and technical feasibility for applying AI and machine learning to wireless LAN systems and devices. The AI Offload Study Group was established in March 2026, and from May 2026 began preparing standardization for offloading computationally intensive AI inference to Wi-Fi access points and wireless edge devices.
AI FOR WLAN
Optimize wireless networks with AI
Apply AI to channel selection, roaming, interference estimation, beam control and operational analysis.
WLAN FOR AI
Distribute AI processing over Wi-Fi
Move device inference to APs or edge computers to balance latency, energy use and computing resources.
POWER FOR EDGE AI
Power becomes more important as the AP becomes a computer
Include AI processing, memory, heat, PoE demand, cooling and UPS capacity in network design.
In the AI era, access points are evolving into edge infrastructure for both communications and computing
An AP supporting edge AI requires monitoring of computing load, temperature, PoE power, firmware, model updates and security in addition to communications traffic. The convergence of AI and wireless networking further accelerates the convergence of communications and power.
View our AI and autonomous distributed power strategy (Japanese) →SENSING / AMBIENT POWER / IoT
Wireless LAN is expanding from a communications path into a sensing and low-power platform
WLAN SENSING
Observe the environment through changes in radio signals
IEEE 802.11bf addresses WLAN Sensing, which estimates properties such as distance, speed, direction and movement from wireless-signal measurements. Communications infrastructure can therefore also function as a sensor for presence, activity and equipment-state detection.
AMBIENT POWER COMMUNICATIONS
Toward devices that do not depend on battery replacement
P802.11bp targets low-power and battery-free applications powered by small amounts of energy harvested from the environment. At large sensor scale, communications performance must be considered together with replacement work, maintenance staffing and disposal of used batteries.
Design device energy efficiency separately from infrastructure power continuity
Devices can move toward harvested energy and battery-free operation, while gateways, access points, backhaul and monitoring platforms retain continuous power. Combining these two distinct power designs enables sustainable operation of large wireless-device fleets.
