1. Product Description
This document describes LITE-ON generic product requirement of 802.11 a/b/g/n/ac dual
band (2.4GHz and 5GHz) concurrent dual radios 3×3:3 indoor AP, which Lite-On product
model is WP838E.
The WP838E structure as SOC QCA9550+1×miniPCIe radio card (Lite-On WM863). One
radio offers 802.11n 450Mbps and another radio offers 802.11ac 1.3Gbps. See Figure-01
In mounting scenario, the WP838E can be deployed as wall mount and ceiling mount.
Via one Giga-bit Ethernet port, the WP838E can connect to the backbone network through
Giga-bit Ethernet interface. Besides, the WP838E also provides 802.3af/at PoE PD which is
able to be powered by PoE switch remotely. The WP838E also supports DC12V power source
option for the environment where PoE is not available.
The WP838E equips six RSMA connectors. (External antenna)

Basically WP838E is supposed to support the below specific software requirements. Most
likely customer will install owned SW rather than Lite-On’ SW, so that we only develop some
necessary SW features so that we can present performance in demo show and also for
certification.

FCC Statement:
Federal Communication Commission Interference Statement
This equipment has been 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. 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:
● Reorient or relocate the receiving antenna.
● Increase the separation between the equipment and receiver.
● Connect the equipment into an outlet on a circuit different from that to which
the receiver is connected.
● Consult the dealer or an experienced radio/TV technician for help.
FCC Caution: Any changes or modifications not expressly approved by the
party responsible for compliance could void the user’s authority to operate this
equipment.
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.
For product available in the USA/Canada market, only channel 1~11 can be
operated. Selection of other channels is not possible.
This device is restricted for indoor use.
IMPORTANT NOTE:
FCC Radiation Exposure Statement:
This equipment complies with FCC radiation exposure limits set forth for an
uncontrolled environment. This equipment should be installed and operated
with minimum distance 20 cm between the radiator & your body.
