Kwikbit is a leader in gigabit wireless distribution solutions that intelligently adapt to
challenging environments to maximize performance and reliability.

The K60i system operates in the 60 GHz unlicensed frequency band and is designed
primarily for line-of-sight (LoS) operation. Non-line-of-sight (NLoS) operation is possible
within short range and in the presence of reflective surfaces. By utilizing advanced
beamforming techniques, the K60i system automatically adapts in Point to Multi-Point
(PMP) communication configuration and is adaptable to changes in the operating
environment. The beam forming capability also makes system installation simple for

                                                                   K60i User Guide

non-technical staff as precise mechanical alignment, as required by previous generation 60
GHz systems, is not required.

The K60i system is designed for use in multiple applications including IoT backhaul
(sensors, security cameras, etc.), optical fiber extension, and corporate and enterprise data
backhaul services by providing 1 Gbps of symmetric throughput.

The K60i system operates in unlicensed Time Division Multiplexing (TDD) band 57.05 –
64.00 GHz in both Point to Point (PTP) and Point to Multi-Point (PtMP) configurations. Some
of the main product characteristics are shown in Table 1.

        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
Kwikbit’s 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. Kwikbit’s
        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 Kwikbit’s 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

                                                                  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 90º azimuthal and 40º
        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.

    ●   The Kwikbit Edge Controller is a very powerful part of the Kwikbit solution. The Edge
        Controller connects through an Ethernet connection to the root K60i unit and
        enables non-technical personnel to physically install an entire network without K60i
        units being configured on the bench in advance. A local or remote IT resource can
        design, commission and manage the network using the Edge Controller’s WebUI.
        The Edge Controller can be connected to the cloud for remote management of
        multiple locations.

The K60i system uses time division duplexing (TDD) access mode, employing a single
frequency for both transmit and receive paths. The throughput for the downlink and uplink
depends on a downlink-to-uplink frame bandwidth ratio. The ratio is automatically
adjusted based on the offered load in each direction, taking into account all Remotes
connected to an Hub in PMP. Furthermore, the system’s throughput depends on the

6 Element and Network Management
The K60i system supports the following network management interfaces:

    ●       K60i Web Interface (WebUI). Accessible via HTTP(S), the K60i WebUI provides an
            interactive visual toolset that allows an operator to modify the full configuration of
            the K60i system as well as view state, fault, and performance indicator.
    ●       The Edge Controller WebUI application provides complete access to configuration,
            state, performance and fault information for all K60i units in a network system.

The WebUI network management interface on the K60i system is accessible via HTTP(S).
Connect to the K60i system with your browser utilizing one of the following methods:

    ●       Local Name​: Connect a K60i transceiver unit directly to your computer by plugging
            an Ethernet cable into any of the K60i’s three RJ45 connectors. In the URL field on
            your computer’s browser type ​https://KB-XX-XX-XX.local​ where ​KB-XX-XX-XX​ is
            the Host name of the unit that appears on the sticker on the back of the unit. For

        example, if the unit Host name is ​KB-C5-6B-78​, then the URL address of the unit is
        https://KB-C5-6B-78.local​. Your browser will display a warning stating that the
        connection is not secure. You may ignore the warning and proceed connecting to
        the unit. To avoid the warning, please go to the Kwikbit support website, download
        the Kwikbit security certificate, and install it on your browser.
    ●   Management IP Address:​ An operator assigned, static, Automatic Private IP
        Addressing (APIPA) or Dynamic Host Configuration Protocol (DHCP) IP address can
        be used for remote management of the units. Both Hubs and Remotes need a
        management IP address. For the Hub, the management IP Address is accessible
        from the Ethernet side of the network, while for the Remote the management IP
        Address is accessible from the wireless side (i.e., from behind the Hub). All traffic to
        and from the management IP address can be encapsulated in an
        operator-configurable VLAN.

The optional Kwikbit Edge Controller’s management application automatically discovers all
connected K60i devices on the network and establishes a secure connection to each one
utilizing a security certificate provided by Kwikbit and customized by the customer. For
more information on the Kwikbit Edge Controller device and associated applications, please
refer to the Kwikbit Edge Controller User Manual.

7 Ethernet Bridge Support
Designed to seamlessly integrate into existing Ethernet backhaul or general-purpose
networks, the K60i system is built for Ethernet connectivity services and provides network
functionality as a standard Layer 2 (L2) Transparent Bridge (IEEE 802.1d), whereby the K60i
cluster (a cluster being one Hub with its group of up to eight Remotes) is the bridge, and
the Ethernet ports on the Hub and associated Remotes are the ports of the bridge.

The embedded bridge functionality performs Media Access Control (MAC) address learning
(up to 4096 MAC addresses). This function allows the Hub to perform an optimal allocation
of radio resources by sending traffic to the Remote behind which the destination of that
traffic is located.

The K60i system allows network management traffic to be encapsulated in a dedicated
management VLAN and can transport standard Ethernet frames (up to 1518 bytes).
