General Description
This specification provides general information regarding the performance and
integration of INPX-400, a complete wireless subsystem featuring UWB
capabilities in a small form factor module. The INPX-400 module is designed to
simplify the process of adding UWB capability without lengthy design cycles or
complex RF design. It is completely tested for functionality and performance
along with coexistence with other wireless standards. A full menu of
certifications will also be provided, simplifying the certification process
for your end product while further reducing valuable time-to-market. Based on
world-class silicon from Decawave, the INPX-400 has been fully optimized for
throughput and receives sensitivity using careful design practices. Software
development resources are available to create and optimize the wireless
subsystem for your application.
The specification maximum and minimum limits presented herein are to serve as
representative performance characteristics of the INPX-400 when properly
designed into a customer’s product. Inpixon makes no warranty, implied or
otherwise specified, with respect to design and performance characteristics
presented in this specification when used in customer designs.
The latest revision of this document supersedes all previous versions of this
document. Inpixon reserves the right to change this specification without
notice.

Host Product Integration
4.1 Integrating Inpixon UWB Module
The Inpixon UWB Module can be integrated into a host controller via a simple
USB interface cable with a 5-pin modular termination and screws to mount the
module board.
4.1.1 Connecting to Inpixon UWB Module
Inpixon UWB Module features a 5-pin 1.5mm-spaced header that provides an
integrated USB serial interface. Refer to the PIN Diagram for the 5-pin
configuration. 4.1.2 Serial Interface
Most modern operating systems would immediately recognize the UWB Module as a
serial device, without additional driver installation. Standard 115200/8-N-1
baud rate configuration is used for serial communication with the Inpixon UWB
Module.
4.1.3 Application Requirements
A UWB device operating under the provisions of this section shall transmit
only when it is sending information to an associated receiver. The UWB
intentional radiator shall cease transmission within 10 seconds unless it
receives an acknowledgment from the associated receiver that its transmission
is being received. An acknowledgment of reception must continue to be received
by the UWB intentional radiator at least every 10 seconds, or the UWB device
must cease transmitting.
4.2Antenna Consideration
4.2.1 Antenna Selection
Inpixon UWB Module’s antenna is tuned for 3.5GHz to 6.5Ghz frequency ranges,
with a peak gain of 5dBi, and efficiency of more than 70% across the bands.
Inpixon UWB Module must be used together with the antenna certified.
4.2.2 RF Exposure Consideration
Host Product Manufacturers must provide RF exposure statements and use
conditions in their end product manuals. If RF exposure statements and use
conditions are not provided, then the host product manufacturer is required to
take responsibility for the module through a change in FCC ID.
4.3Host Product Manufacturer Notice
The modular transmitter is only FCC authorized for the specific rule parts
listed on the grant (47 CFR Part 15 Subpart F), and the host product
manufacturer is responsible for compliance with any other FCC rules that apply
to the host not covered by the modular transmitter grant of certification. If
the host product the manufacturer markets their product as being Part 15
Subpart B compliant (when it also contains unintentional-radiator digital
circuity), then the host product manufacturer shall provide a notice stating
that the final host product still requires Part 15 Subpart B compliance
testing with the modular transmitter installed.
In addition, the Host Product Manufacturer must comply with the following
regulations:
- The INPX-400 modular transmitter must be labeled with its own FCC ID number, and, if the FCC ID is not visible when the module is installed inside another device, then the outside of the device into which the module is installed must also display a label referring to the enclosed module.
- This exterior label can use wording such as the following:
IMPORTANT: Contains FCC ID: 2AVTI-INPX400. This equipment complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.
4.3.1 OEM Integrator Text
This device is intended only for OEM integrators under the following
conditions: The module must be installed in the host equipment such that the
antenna(s) used for this transmitter must be installed to provide a separation
distance of at least 5mm from all persons and must not be co-located or
operating in conjunction with any other antenna or transmitter.
The module shall be only used with the antenna that has been originally tested
and certified with this module. The antenna shall not be modified. However,
the OEM integrator is still responsible for testing their end‐product for any
additional compliance requirements required with this module installed
(forexample, digital device emissions, PC peripheral requirements, etc.). The
end‐product may need Verification testing, Declaration of Conformity testing,
a Permissive Class II Change, or new Certification. Please involve an FCC
certification specialist in order to determine what will be precisely
applicable for the end product.
End product labeling: This transmitter module is authorized only for use in a
device where the antenna may be installed to ensure satisfying RF exposure
compliance. The final end product must be labeled in a visible area with the
following: “Contains FCC ID: 2AVTI-INPX400”, “Contains ISED ID: 26211INPX400”.
The OEM integrator has to be aware not to provide information to the end-user
regarding how to install or remove this RF module in the user’s manual of the
end product, which integrates this module. The end-user manual shall include
all required regulatory information/warning, as shown in this manual.
The Host Product Integration section must be followed when integrating this
device, including regulating the 10-second transmission cease requirement
(4.1.3 Application Requirements).
4.3.2 FCC 15.519 compliance for Handheld Operation
Inpixon UWB Module complies with FCC Part 15.519. The manufacturer claims that
the communication between the UWB Modules and other devices is for time
synchronization only. The transmission from this module is a beacon-type
periodic signal (default 150 ms) and will not contain any information.
4.3.3 FCC 15.250 compliance on 5925-7250 MHz
Inpixon UWB Module, when limited to channel 5 and 7 transmissions, complies
with FCC Part 15.250.
Operation is subject to other operation limitations in this document and must
prevent, e.g. via firmware, transmitting on any channel except channels 5 and
7 (allowed frequencies in range 5925 – 7250 MHz).
In addition, operation on board an aircraft or a satellite is prohibited.
Devices operating under this section may not be employed for the operation of
toys. Except for operation onboard a ship or a terrestrial transportation
vehicle, the use of fixed outdoor infrastructure is prohibited. A fixed
infrastructure includes antennas mounted on outdoor structures, e.g., antennas
mounted on the outside of a building or on a telephone pole.
