Introduction
The SocketWireless® Wi-Fi® device server connects serial devices to an IP network via 802.11b/g wireless
networking. It enables you to build wireless networking into virtually any device allowing for remote monitoring, control
and configuration. The space efficient communications device (1” x 2.5”) integrates a complete TCP/IP protocol stack.
It can make your existing and next generation device, machine or system, IP-ready while you focus on developing its
core features.

Regulatory Requirements for the Wi-Fi Antenna
This section covers how to use the modular transmitter in order to maintain the modular transmitter approval
and RF exposure compliance.
Conditions to Satisfy Modular Transmitter Approval
This device is intended only for use by OEM integrators under the following 3 conditions:
1. The antenna must be installed such that 20 cm is maintained between the antenna and
the end user for all installations.
2. The transmitter module may not be located with any other transmitter or antenna.
3. The communications device is approved using the FCC "unlicensed modular transmitter
approval" method. Therefore, the communication device must only be used with the
originally approved antennas.
As long as the 3 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 with this communication device installed (for example, digital device emissions, PC
peripheral requirements, etc.)
IMPORTANT NOTE: In the event that any of these conditions CANNOT be met (for example
certain laptop configurations, location with another transmitter, or use of a different type antenna),
then the FCC authorization for the communications device is no longer considered valid and the
FCC ID CANNOT be used on the final product. In these circumstances, the OEM integrator will be
responsible for re-evaluating the end product (including the transmitter) and obtaining a separate
FCC authorization.
RF Exposure Statements Developers Must Include in the User Manual for End Users
The user manual for consumers must include the following information in a prominent location:
IMPORTANT NOTE: To comply with FCC RF safety exposure limits, the antenna used for this
transmitter must be installed to provide a separation distance of at least 20 cm from all persons and
must not be located or operating in conjunction with any other antenna or transmitter.
Regulatory Requirements for End Product Labeling
Suggested End Product Labeling
This transmitter module is authorized only for use in devices where the antenna may be installed in
such a way that 20 cm may be maintained between the antenna and the users (for example access
points, routers, wireless ASDL modems, and similar equipment). The final end product must be
labeled in a visible area on the exterior of the enclosure with the following or similar text: "Contains
TX FCC ID: AU792U07B06821".
FCC & IC Information to Consumers
The user manual for the consumer must contain the statements required by the following FCC and
IC regulations: 47 C.F.R. 15.19(a)(3), 15.21, 15.101 and RSS-Gen Issue 2 dated June 2007,
Sections 7.1.4 and 7.1.5.
Additional Information That Must Be Provided to OEM Integrators
Part 4 – Embedded Device Servers Chapter 10 – SocketWireless Wi-Fi (MT810SWM-IP)
The end user should NOT be provided any instructions on how to remove or install the modular
transmitter.
