within short range and in the presence of reflective surfaces. By utilizing advanced
beamforming techniques, the K60c system automatically adapts in Point-to-Multipoint
(PtMP) communication configuration and is adaptable to changes in the operating
environment. The beam forming capability also makes system installation simple for
non-technical staff as precise mechanical alignment, as required by previous generation 60
GHz systems, is not required.
The K60c system is designed for use in multiple applications including gigabit access, IoT
backhaul (sensors, security cameras, etc.), optical fiber extension, and corporate and
enterprise data services by providing 1 Gbps of symmetric throughput.
The K60c system operates in unlicensed Time Division Multiplexing (TDD) band 57.05 –
64.00 GHz in both Point-to-Point (PtP) and Point-to-Multipoint (PtMP) configurations. Some
of the main product characteristics are shown in Table 1.

The K60c system consists of the following components:
●Hub Unit: control communication to one or more Remote Units
●Remote Unit: scan for available Hub Units and connect to the Hub configured or
assigned via the Edge Controller
●Edge Controller: Optional appliance computer that provides WebUI tools for
deployment planning, commissioning, network configuration, management,
monitoring and fault isolation. Edge controller is highly recommended for networks
of medium and large scale.
The K60c Hub and Remote Units are identical from a hardware perspective, only differing
in software configuration. The K60c has a small form factor that can be easily and
unobtrusively deployed in many different outdoor environments.
K60c units will interoperate with other products in the Kwikbit K60 product line.
4 K60c System Description
Kwikbit’s K60c wireless outdoor networking 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 (PtMP) wireless Ethernet bridge.
Some of the main characteristics of the system include:
●Time Division Duplex (TDD): The K60c solution features TDD access mode with
variable frame length.
●Adaptive Modulation with Link Adaptation: The K60c system supports BPSK,
QPSK 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 K60c 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
Kwikbit K60c User Guide - 8 -
K60c User Guide
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 K60c
beamforming is that non-technical personnel can quickly and easily install the
system. Precise physical alignment of the radios, as required with previous 60 GHz
products, is not required with the Kwikbit system. The beamforming feature also
enables the PtMP communication capability of the system.
●Power Management: The K60c 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 K60c 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 K60c units integrate a specially-designed antenna
module that enables a 90º azimuthal and 40º vertical beam sweep range.
●PtMP with Dynamic Bandwidth Allocation: The K60c system can operate in PtP or
PtMP 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 K60c transceiver units are highly integrated, compact,
and lightweight, so they can be easily mounted on poles, pipes and walls.
●Connectivity: K60c devices include a standard RJ45 Gigabit Ethernet port that
serves as a PoE In port.
The Kwikbit K60c system provides these network management features:
●Each K60c 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 K60c User Guide - 9 -
K60c User Guide
●A command-line interface (CLI) is also available. It provides features similar to those
of the WebUI.
Figure 2: K60c Hub and Remote WebUI interface page
●The Kwikbit Edge Controller is a very powerful part of the Kwikbit solution. The Edge
Controller connects through an Ethernet connection to the root K60c unit and
enables non-technical personnel to physically install an entire network without K60c
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.

network connectivity and PoE power input (802.3at, 802.3at+, or 802.3bt).
6 System Throughput
The K60c 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 a Hub in PtMP. Furthermore, the system’s throughput depends on the
Modulation and Coding Rate (MCS) which varies according to link and signal conditions. The
following table details Ethernet uplink and downlink combined throughput for a K60c link.

8 Ethernet Bridge Support
Designed to seamlessly integrate into existing Ethernet networks, the K60c system is built
for Ethernet connectivity services and provides network functionality as a standard Layer 2
(L2) Transparent Bridge (IEEE 802.1d), whereby the K60c cluster (a cluster being one Hub
with its group of up to seven 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 K60c system allows network management traffic to be encapsulated in a dedicated
management VLAN and can transport standard Ethernet frames, including oversize frames
(up to 1600 bytes including the FCS).
9 Installation Planning
When unpacking K60c units during install, be sure to do the following for each unit:
●Locate the label on the unit casing that lists the Serial Number (SN) and Host name
of the unit
●Record the SN on your registration card for future reference
●Record the Host name for future reference when provisioning the system
After installation of the K60c, perform the tasks described in Chapter 12 “System
Provisioning”.
