TRANSCEIVER IC
CEL’s MeshConnect EM357 Mini Modules use the Ember EM357 transceiver IC. This IC incorporates the RF transceiver
with the baseband modem, a hardwired MAC, and an embedded ARM® Cortex™-M3 microcontroller, offering an excellent
low cost high performance solution for all IEEE 802.15.4 / ZigBee applications.

ANTENNA
CEL’s MeshConnect EM357 Mini Modules include an integrated Printed Circuit Board (PCB) trace antenna. An optional
configuration with a Castellation pin is available for a connection to a 50-ohm external antenna of the user’s choice.
However use of an external antenna is not covered by the module's certification. See Ordering Information on Page 1.
The PCB antenna employs a topology that is compact and highly efficient. To maximize range, an adequate ground plane
must be provided on the host PCB. Correctly positioned, the ground plane on the host PCB will contribute significantly to the
antenna performance (it should not be directly under the module PCB Antenna). The position of the module on the host board
and overall design of the product enclosure contribute to antenna performance. Poor design affects radiation patterns and
can result in reflection, diffraction and/or scattering of the transmitted signal.
For optimum antenna performance, the MeshConnect modules should be mounted with the PCB trace antenna overhanging
the edge of the host board. To further improve performance, a ground plane may be placed on the host board under the
module, up to the antenna (a minimum of 1.5" x 1.5" is recommended). The installation of an uninterrupted ground plane on
a layer directly beneath the module will also allow you to run traces under this layer. CEL can provide assistance with your
PCB layout.
Here are some design guidelines to help ensure antenna performance:

Under Industry Canada regulations, this radio transmitter may only operate using an antenna of a type and maximum (or
lesser) gain approved for the transmitter by Industry Canada. To reduce potential radio interference to other users, the
antenna type and its gain should be so chosen that the equivalent isotropically radiated power (e.i.r.p.) is not more than that
necessary for successful communication.
Conformément à la réglementation d'Industrie Canada, le présent émetteur radio peut fonctionner avec une antenne
d'un type et d'un gain maximal (ou inférieur) approuvé pour l'émetteur par Industrie Canada. Dans le but de réduire les
risques de brouillage radioélectrique à l'intention des autres utilisateurs, il faut choisir le type d'antenne et son gain de
sorte que la puissance isotrope rayonnée équivalente (p.i.r.e.) ne dépasse pas l'intensité nécessaire à l'établissement d'une
communication satisfaisante.
POWER AMPLIFIER
CEL’s MeshConnect EM357 High Power Module (ZICM357SP2) includes a Power Amplifier (PA). This PA delivers
high efficiency, high gain, and high output power (Pout = +20.0 dBm TYP) to provide an extended range and reliable
transmission for fewer nodes in a network. For the ZICM357SP2, Power mode 2 with Power Setting "-2" is the maximum
setting allowed for FCC compliance. Operating in power mode 3 at higher power settings may damage the power amplifier.
SOFTWARE/FIRMWARE
CEL’s
field proven ZigBee compliant stack supporting the ZigBee PRO feature Set. EmberZNET PRO is a complete ZigBee
protocol software package containing all the elements required for mesh networking applications. For more information
regarding the software development for this IC, visit
CEL provides reference software that runs multiple functions and executes various commands. The firmware allows the
execution of IEEE 802.15.4 communication, validation and manufacturing tests. For example, users can setup a simple
ZigBee Point-to-Point network to perform Range and Packet Error Rate (PER) tests. The software can also place the module
in various operating modes, which allows for setting and/or testing various parameters.
The ZICM357SP0 uses the transceiver's Primary RF ports for transmitting and should use power mode 1.
The ZICM357SP2 uses the transceiver's Alternate RF ports for transmitting and should use power mode 2.
Never place the ground plane or route copper traces directly underneath the antenna portion of the module.
Never place the antenna close to metallic objects.
In the overall design, ensure that wiring and other components are not placed near the antenna.
Do not place the antenna in a metallic or metalized plastic enclosure.
Keep plastic enclosures 1cm or more from the antenna in any direction.
