Edgewater Wireless Proprietary Information 2
1 Introduction
The EWC24GWFR1 mini-PCI card is multi-channel WiFi card. It simultaneously supports 3 independent
IEEE 802.111bg compatible radio channels.
The EWC24GWFR1 enables the OEM to build high capacity WiFi Access Points for unique high
performance applications.
Module Summary
•Compliant with IEEE 802.11b/g
•FCC and IC certification
•Operating frequency range 2412-2462 MHz, locked by radio firmware

3 RF Guidelines
The EWC24GWFR1 card is certified to FCC and Industry Canada specifications for use in unlicensed
band applications operating at 2.412 to 2.462 GHz.
License ID:
FCC ID: ATX-EWC24GWFR1
IC: 10165A-EWC24GWFR1
To ensure compliance to the regulations for unlicensed band radio spectrum the system integrator must
observe the following guidelines:
•User accessible Antenna ports shall be unique connectors for purpose selected antenna
•The maximum EIRP of the final system product with external antenna shall be limited to 30dBm
•A system incorporating this module shall be designed by an RF Engineer such that a professional
installer can ensure that the combination of the selected antenna and maximum Transmit power
level shall not exceed maximum EIRP of 19.25dBi. (16.25dBm-card output power + 3dBi
antenna gain)
•The host communication interface to the radio module is proprietary and unique to Edgewater
Wireless (i.e. not open source). Specifically, the multi-channel interface API (Application Program
Interface) is of a unique architecture requiring specific knowledge of the configuration parameters
and data path algorithms to make it operational. Approved system Integrators must contact
Edgewater Wireless and apply for access to the required application notes that are limited to
approved integrators and is covered by non-disclosure agreements.
•Maximum conducted Output Power
o3 Channels 16.25dBm, +/- 0.5dBm
o2 Channel 16.25 +/-0.5 dBm total; 13.25dBm +/- 0.5dBm per carrier
o1 Channel 16.25 +/-0.5 dBm total; 11.55dBm +/- 0.5dBm per carrier
3.1 Compliance
Regulatory
•This radio transmitter, 10165A-EWC24GWFR1, has been approved by Industry Canada to
operate with the antenna types listed below with the maximum permissible gain indicated.
Antenna types not included in this list, having a gain greater than the maximum gain indicated for
that type, are strictly prohibited for use with this device.
•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 equipment has been tested and found to comply with the limits for a Class A digital device,
pursuant to part 15 of the FCC Rules and with Industry Canada licence-exempt RSS standard(s) .
These limits are designed to provide reasonable protection against harmful interference when the
equipment is operated in a commercial environment.
•This equipment generates, uses, and can radiate radio frequency energy and, if not installed and
used in accordance with the instruction manual, may cause harmful interference to radio
communications. Operation of this equipment in a residential area is likely to cause harmful
interference in which case the user will be required to correct the interference at his own
expense. Any modifications by the user of the product may void the user’s authority to operate
the product.
Antenna
•Maximum Antenna Gain 3dBi

Edgewater Wireless Proprietary Information 5
•Separate TX & RX antenna port via on-card non-standard RP-U.FL (UMCC) PCB connectors
•Authorized Antenna for Laird Part# RD2458-5-RSMA (reverse polarity SMA male connector) or
equivalent antenna
•“The antenna(s) used for this transmitter must be installed to provide a separation distance of at
least 20 cm from all persons and must not be co-located or operating in conjunction with any
other antenna or transmitter.”
Product Labels
•“The outside of the device into which the module is installed must display a label with Contains
FCC ID: ATX-EWC24GWFR1, Contains IC: 10165A-EWC24GWFR1”
4 Thermal Considerations
The radio dissipates a maximum of 7.6watts. Consideration must be given to thermal management such
that sensitive components on the card do not exceed their maximum operation temperature. It is
recommended that the integrator use an aluminum heat sink adjacent to the RF shield.
The following table provides thermal info and constraints that the integrator must consider in designing
the thermal management scheme.
