All information contained herein is provided “AS IS.” Lantronix undertakes no obligation to

update the information in this publication. Lantronix does not make, and specifically disclaims,

all warranties of any kind (express, implied or otherwise) regarding title, non-infringement,

fitness, quality, accuracy, completeness, usefulness, suitability or performance of the

information provided herein. Lantronix shall have no liability whatsoever to any user for any

damages, losses and causes of action (whether in contract or in tort or otherwise) in

connection with the user’s access or usage of any of the information or content contained

herein. The information and specifications contained in this document are subject to change

without notice.

This equipment has to be tested and found to comply with the limits for a Class B digital

device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable

protection against harmful interference in a residential installation. This equipment generates,

uses, and can radiate radio frequency energy and, if not installed and used in accordance with

the instructions, may cause harmful interference to radio communications. However, there is

no guarantee that interference will not occur in a particular installation.

PremierWave® 2050 802.11ac Embedded Wi-Fi® IoT Gateway Integration Guide 3

If this equipment does cause harmful interference to radio or television reception, which can be

determined by turning the equipment off and on, the user is encouraged to try to correct the

interference by one of the following measures:

1. Reorient or relocate the receiving antenna.

2. Increase the separation between the equipment and receiver.

3. Connect the equipment into an outlet on a circuit different from that to which the receiver

is connected.

4. Consult the dealer or an experienced radio/TV technician for help.

This device 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.

This device is intended only for OEM Integrators. The OEM integrator should be aware of the

following important considerations.

Labeling of the End Product

The label on the end product incorporating the PremierWave 2050 gateway must clearly state

that it contains an FCC-approved RF gateway. Canada and Japan also require a similar

statement.

For example, “This product contains RF transmitter ID # (put FCC, IC, CMIIT, and/or Japan

gateway grant numbers here).” The label must include the ID numbers for the regions where

the end product is installed. The grant numbers are below.



PremierWave 2050 FCC ID number: R68PW2050



PremierWave 2050 IC ID number: 3867A-PW2050



PremierWave 2050 Japan ID numbers: 201-152843



PremierWave 2050 China SRRC CMIIT ID: 2015AJ6847 (M)

RSS-GEN Sections 7.1.4 and 7.1.5 Statement for Devices with

Detachable Antennas

This device has been designed to operate with the antennas listed in the Certificate, and

having a maximum gain of 5.5 dBi. Antennas not included in this list or having a gain greater

than 5.5 dBi are strictly prohibited for use with this device, unless system level approval is

gained. The required antenna impedance is 50 ohms.

To reduce potential radio interference to other users, the antenna type and its gain should be

so chosen that the equivalent isotropically radiated power (EIRP) is not more than that

required for successful communication.

PremierWave® 2050 802.11ac Embedded Wi-Fi® IoT Gateway Integration Guide 4

Integration Notes

This gateway is authorized under limited gateway approval specific to mobile host equipment.

The antenna must be installed with a 20 cm space maintained between the antenna and users.

The transmitter gateway may not be co-located with any other transmitter or antenna.

As long as the two conditions above are met, further transmitter testing will not be required.

However, the OEM integrator is still responsible for testing their end product for any additional

compliance requirements required with this gateway installed (for example, digital device

emission, PC peripheral requirements, etc.)

In the event that these conditions cannot be met (for example certain laptop configurations,

general purpose PCMCIA or similar cards, or co-location with another transmitter) and

obtaining a separate FCC authorization will be required, then the FCC authorization is no

longer considered valid and the FCC ID cannot be used on the final product (including the

transmitter).

Changes or modifications to this device not explicitly approved by Lantronix will void the user's

authority to operate this device.

Note: With the purchase of any PremierWave 2050 family product, the OEM agrees to an

OEM firmware license agreement that grants the OEM a non-exclusive, royalty-free

firmware license to use and distribute the binary firmware image provided, only to the

extent necessary to use the PremierWave 2050 hardware. For further details, please see

the PremierWave 2050 OEM firmware license agreement.

Note: Please refer to the PremierWave 2050 802.11ac Embedded Wi-Fi IoT Gateway

Datasheet, available at www.lantronix.com/support/documentation, for the full compliance

specification and requirements.

2:Functional Description

Designed for quick integration with minimal engineering effort, the chip-sized PremierWave

2050 gateway provides simplicity and flexibility making it the easiest and fastest networking-

enabling gateway on the market.

PremierWave 2050 gateways are extremely compact networking solutions that enable

Ethernet or wireless connectivity on virtually any device with a serial interface. The included

industry-proven Lantronix gateway application and full IP stack allow seamless remote access

to device data simplifying design integration while providing robust connectivity.

The PremierWave 2050 gateway s can be utilized in designs typically intended for chip

solutions. A key difference with the PremierWave 2050 gateway is that there is virtually no

need to write a single line of code, translating to a much lower development cost and faster

time-to-market.
