K60i User Guide monitoring and fault isolation. Edge controller is highly recommended for networks of medium and large scale. The K60i Hub and Remote Units are identical from a hardware perspective, only differing in software configuration. The K60i has a small form factor that can be easily and unobtrusively deployed in many different indoor environments. 3 K60i System Description Kwikbits K60i wireless indoor backhaul solution is designed to meet the requirements of network planners where rapid and flexible deployment, high reliability, multi-gigabit capacity and excellent latency performance are needed. Applications for the system include IoT gateway aggregation, Wi-Fi access point backhaul, video camera connectivity and other gigabit IP based applications. The system can function either as a Point-to-Point (PTP) or Point-to-Multipoint (PMP) wireless Ethernet bridge. Some of the main characteristics of the system include:

Time Division Duplex (TDD): The K60i solution features TDD access mode with variable frame length. Adaptive Modulation with Link Adaptation: The K60i system supports BPSK, QPSK and 16QAM on both the downlink and uplink path to achieve high capacity in the channel bandwidth (1.86 Gbps Ethernet layer throughput for combined downlink and uplink traffic). Beamforming: Use of the 60 GHz band allows extremely fast communication, but also presents the challenge of limited propagation. Signals in the 60 GHz band are also more susceptible to disruption from physical barriers than at lower frequencies. The K60i system includes adaptive beamforming, a technique that enables robust multi-gigabit communications at greater distances. Kwikbits beamforming feature uses directional antennas to reduce interference and automatically focus a signal between two devices into a concentrated beam. During the beamforming process, devices establish communication and then fine-tune their antenna settings to improve the quality of directional communication until there is enough capacity for the desired data transmission. One key benefit of Kwikbits beamforming is that if an obstacle blocks the line of sight between two devices, for example, if someone walks between them, the devices can quickly establish a new communications pathway. Another benefit of the K60i beamforming is that non-technical personnel can quickly and easily install the system. Precise physical alignment of the radios, as required with previous 60 Kwikbit K60i User Guide Confidential & Proprietary

- 9 -

K60i User Guide GHz products, is not required with the Kwikbit system. The beamforming feature also enables the PMP communication capability of the system. Power Management: The K60i system utilizes the scheduled access mode to reduce power consumption. Devices connected with each other via a directional link schedule the periods during which they communicate and, in between those periods, they can sleep to save power. This capability allows devices to more precisely tailor their power management to their actual traffic workload, reduces potential co-channel interference and enables efficient spectrum utilization. Advanced Security: The K60i system utilizes strong security mechanisms, including Galois/Counter Mode, a highly-efficient mode of encryption that is designed to support higher communication speeds. Encryption is based on the government-grade Advanced Encryption Standard (AES) and is implemented in hardware for performance and efficiency. Integrated Antennas: The K60i units integrate a specially-designed, 64 element antenna module that enables a peak EIRP of 40 dBm with a 90 azimuthal and 40 vertical beam sweep range. PMP with Dynamic Bandwidth Allocation: The K60i system can operate in PTP or PMP configurations with up to eight Remotes. The capacity allocated to each Remote is variable according to the requirements of connected devices. Compact Form Factor: The K60i transceiver units are highly integrated, compact

(107x107x50mm), and low in weight (388g), so they can be easily mounted on most ceiling structures and walls. Connectivity: K60i backhaul devices include three standard RJ45 Gigabit Ethernet ports, two of which supply PoE power to connected Wi-Fi access points, IoT gateways, surveillance cameras and other payload communication devices. The Kwikbit K60i system provides these network management features:

Each K60i unit incorporates a WebUI. This WebUI enables configuration, fault management, and administration of the unit, as well as provides system state and performance information. Kwikbit K60i User Guide Confidential & Proprietary
