WGM160P Wi-Fi
Module Data Sheet
The WGM160P is an ultra low power standalone Wi-Fi
®
module targeted for applications
requiring superior RF performance in noisy environments, low power consumption, high
KEY POINTS
security, integrated customer applications and fast time to market.
• Available
with integrated chip antenna or
an RF pin
The WGM160P module integrates all of the necessary elements required for a cloud
connected IoT Wi-Fi application, including 802.11b/g/n radio, integrated chip antenna,
certifications, microcontroller, Wi-Fi and IP stacks, HTTP server, and multiple protocols,
such as TCP and UDP. Co-existence with external 2.4GHz transceivers is supported.
• Antenna
diversity supported via secondary
RF pin
• IEEE
802.11 b/g/n compliant
• TX
power: +16 dBm
WGM160P can be configured to concurrently act as a Wi-Fi client and a Wi-Fi access
point, which is ideal for user friendly device provisioning. WGM160P can natively host C-
applications, removing the need for an external host controller. Alternatively, the Wi-Fi
Module can run in Network Co-Processor (NCP) mode, leaving the complexity of TCP/IP
networking to the module so that the customer’s own host controller can be fully dedica-
ted to processing the customer application tasks. The WGM160P module has highly
flexible host and peripheral hardware interfaces for wide application use.

Module Data Sheet
Typical Applications and Connections
5. Typical
Applications and Connections
5.1 RF
Connections
5.1.1 Antenna
Ports
The WGM160P offers two RF ports that support antenna diversity using an internal switch. In applications with only one antenna, the
unused port should be terminated to ground with a 47-51 Ω resistor. Leaving the unused port floating or tying directly to ground will
result in degraded performance. An external antenna connected to either RF port needs to be properly matched with at least -10dB
return loss (VSWR < 2).
5.1.2 Antenna
Diversity
In applications where multipath fading is a potential issue, such as indoors, a second antenna can be connected. A firmware feature
can be enabled to automatically determine which of the two antennas gives a better signal, allowing significant improvement in link reli-
ability.
5.2 Multi-Protocol
Coexistence
Packet Transmit Arbitration (PTA) pins are provide to share antenna and optimize coexistence performance with other networks includ-
ing other protocols. See Application Notes
AN1128: Bluetooth Coexistence with Wi-Fi
,
AN1017: Zigbee and Thread Coexistence with
Wi-Fi
and AN1224 Wi-Fi Coexistence with other 2.4GHz Radio Protocols for more information.

Module Data Sheet
Software Options
6. Software
Options
Several Wi-Fi Software options are available for the WGM160P. There are FMAC (Full MAC) driver examples as well as Gecko OS.
Gecko OS is a full-feature IoT operating system that provides networking and internet communications, security and includes over the
air firmware updates and cloud connectivity.
6.1 FMAC
(Full MAC) Driver
6.1.1 Architecture
Utilizing the Full MAC driver, both the lower MAC and upper MAC are running in WF200 of the WGM160P. The WF200 contains a
WPA/WPA2 personal supplicant, allowing it to handle full MAC responsibilities without utilizing the host MCU. The host receives an IP
packet and implements all stack layers necessary above it. The figure below shows the typical software architecture in Full MAC imple-
mentations.
Figure 6.1.
Full MAC Implementation
Note:
The WPA supplicant on WF200 does not support WPA enterprise. If WPA-enterprise is required, then it should be implemented
above the IP stack in the EFM32GG11 software.
6.1.2 Examples
Numerous software examples are available from Simplicity Studio or the GitHub repository. These examples utilize the MicriumOS Ker-
nel, FreeRTOS or Bare Metal (no RTOS). Unless otherwise specified in the repository, all examples are considered to be EXPERIMEN-
TAL QUALITY which implies that the code provided in the repos has not been formally tested and is provided as-is. They are not suita-
ble for production environment.

Certain alternate function locations may have non-interference priority. These locations will take precedence over any other functions
selected on that pin (i.e. another alternate function enabled to the same pin inadvertently).
Some alternate functions may also have high speed priority on certain locations. These locations ensure the fastest possible paths to
the pins for timing-critical signals.
The following table lists the alternate functions and locations with special priority.

External Antenna Types
This device has been certified with an integrated chip antenna as well as external antennas connected to either RF port or both. The
required antenna impedance is 50 Ω.
Table 11.1.
Qualified Antennas for WGM160P
Antenna Type
Maximum Gain
Connectorized Coaxial Dipole
2.14 dBi
Any antenna of the same general type and of equal or less directional gain as listed in the above table can be used in the regulatory
areas that have a full modular radio approval (USA, Canada, Korea, Japan) as long as spot-check testing is performed to verify that no
performance changes compromising compliance have been introduced. In countries applying the ETSI standards, like the EU countries,
the radiated emissions are always tested with the end-product and the antenna type is not critical, but antennas with higher gain may
violate some of the regulatory limits.
If an antenna of a different type (such as a chip antenna, a PCB trace antenna or a patch) with a gain less than or equal to 2.14 dBi is
needed, it can be added as a permissive change, requiring some radiated emission testing. Antenna types with more gain than 2.14 dBi
may require a fully new certification. Since the exact permissive change procedure is chosen on a case by case basis, please consult
your test house, for example while performing with them the EMC testing of the end-product.
11.2 CE
The WGM160P22A and WGM160P22N module is in conformity with the essential requirements and other relevant requirements of the
Radio Equipment Directive (RED) (2014/53/EU). Please note that every application using the WGM160P22A and WGM160P22N will
need to perform the radio EMC tests on the end product, according to EN 301 489-17. It is ultimately the responsibility of the manufac-
turer to ensure the compliance of the end-product. The specific product assembly may have an impact to RF radiated characteristics,
and manufacturers should carefully consider RF radiated testing with the end-product assembly. A formal Declaration of Conformity

11.3 FCC
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 undesirable operation.
Any changes or modifications not expressly approved by Silicon Labs could void the user’s authority to operate the equipment.
FCC RF Radiation Exposure Statement:
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. End users must follow the specif-
ic operating instructions for satisfying RF exposure compliance. This transmitter meets both portable and mobile requirements in ac-
cordance to the limits exposed in the RF Exposure Analysis. This transmitter must not be co-located or operating in conjunction with
any other antenna or transmitter except in accordance with FCC multi-transmitter product procedures.
OEM Responsibilities to comply with FCC Regulations:
OEM integrator is responsible for testing their end-product for any additional compliance requirements needed with this module instal-
led (for example, digital device emissions, PC peripheral requirements, etc.). Additionally, investigative measurements and spot check-
ing are strongly recommended to verify that the full system compliance is maintained when the module is integrated, in accordance to
the “Host Product Testing Guidance” in FCC’s KDB 996369 D04 Module Integration Guide V01.
• In
the typical case when the integral antenna of the WGM160P22A is used, a minimum separation distance of 40 mm must be main-
tained at all times between the human body and the radiator (antenna) to meet the SAR exemption for portable conditions. When the
WGM160P22N is used instead, the minimum separation distance is also 40 mm, unless only the RF port 2 is used with a dipole
antenna, in which case the minimum distance is 37 mm.
• The
transmitter module must not be co-located or operating in conjunction with any other antenna or transmitter except in accord-
ance with FCC multi-transmitter product procedures.
Important Note:
In the event that these conditions cannot be met, then for the FCC authorization to remain valid the final product will have to undergo
additional testing to evaluate the RF exposure, and a permissive change will have to be applied with the help of the customer’s own
Telecommunication Certification Body.

11.4 ISED
Canada
ISED
This radio transmitter (IC: 5123A-WGM160P) has been approved by
Innovation, Science and Economic Development Canada (ISED
Canada, formerly Industry Canada
) to operate with the antenna types listed above, with the maximum permissible gain indicated. An-
tenna types not included in this list, having a gain greater than the maximum gain listed, are strictly prohibited for use with this device.
This device complies with ISED’s license-exempt RSS standards. Operation is subject to the following two conditions:
1. This device may not cause interference; and
2. This device must accept any interference, including interference that may cause undesired operation of the device
RF Exposure Statement
Exemption from routine SAR evaluation limits are given in RSS-102 Issue 5.
The models WGM160P22A and WGM160P22N meet the given exemption requirements when the minimum separation distance be-
tween the antenna(s) and the human body is respectively 30 mm and 40 mm. In the case of the N variant, the minimum separation
distance could also be 30 mm but only in the case of using exclusively the dipole antenna at RF port 2, without configuring any trans-
mission out of RF port 1.
In other words, RF exposure or SAR evaluation is not required when the separation distance is same or more than stated above. If the
separation distance is less than stated above the OEM integrator is responsible for evaluating the SAR when using the module at its
highest transmission power.
OEM Responsibilities to comply with IC Regulations
The WGM160P modules have been certified for integration into products only by OEM integrators under the following conditions:
• The
antenna(s) must be installed such that a minimum separation distance as stated above is maintained between the radiator (an-
tenna) and all persons at all times.
• The
transmitter module must not be co-located or operating in conjunction with any other antenna or transmitter.
As long as the two conditions above are met, further transmitter testing will not be required. However, the OEM integrator is still respon-
sible for testing their end-product for any additional compliance requirements required with this module installed (for example, digital
device emissions, PC peripheral requirements, etc.).
IMPORTANT NOTE
In the event that these conditions cannot be met, then for the ISED authorization to remain valid the final product will have to undergo
additional testing to evaluate the RF exposure, and a permissive change will have to be applied with the help of the customer’s own
Telecommunication Certification Body.
End Product Labeling
The WGM160P module is labeled with its own ISED ID. If the ISED ID is not visible when the module is installed inside another device,
then the outside of the device into which the module is installed must also display a label referring to the enclosed module. In that case,
the final end product must be labeled in a visible area with the following:
“
Contains Transmitter Module IC: 5123A-WGM160P
”
or
“

Déclaration d’exposition RF
L’exemption tirée des limites courantes d’évaluation DAS est donnée dans le document RSS-102 Issue 5.
Les modèles WGM160P22A et WGM160P22N respectent les exigences d’exemption prévues lorsque la distance de séparation mini-
male entre le(s) antenne(s) et le corps humain est respectivement de 30 mm et 40 mm. Dans le cas de la variante N, la distance mini-
male de séparation pourrait également être de 30 mm, mais uniquement dans le cas d’une utilisation exclusive de l’antenne dipôle sur
le port RF 2, sans configurer de transmission sur le port RF 1.
La déclaration d’exposition RF ou l’évaluation DAS n’est pas nécessaire lorsque la distance de séparation est identique ou supérieure à
celle indiquée ci-dessus. Si la distance de séparation est inférieure à celle mentionnées plus haut, il incombe à l’intégrateur OEM de
procédé à une évaluation DAS.
Responsabilités des OEM pour une mise en conformité avec le Règlement du Circuit Intégré
Le module WGM160P a été approuvé pour l’intégration dans des produits finaux exclusivement réalisés par des OEM sous les condi-
tions suivantes:
• L’antenne
(s) doit être installée de sorte qu’une distance de séparation minimale indiquée ci-dessus soit maintenue entre le radiateur
(antenne) et toutes les personnes avoisinante, ce à tout moment.
• Le
module émetteur ne doit pas être localisé ou fonctionner avec une autre antenne ou un autre transmetteur que celle indiquée
plus haut.
Tant que les deux conditions ci-dessus sont respectées, il n’est pas nécessaire de tester ce transmetteur de façon plus poussée. Ce-
pendant, il incombe à l’intégrateur OEM de s’assurer de la bonne conformité du produit fini avec les autres normes auxquelles il pour-
rait être soumis de fait de l’utilisation de ce module (par exemple, les émissions des périphériques numériques, les exigences de pé-
riphériques PC, etc.).
REMARQUE IMPORTANTE
Dans le cas où ces conditions ne peuvent être satisfaites (pour certaines configurations ou co-implantation avec un autre émetteur),
l’autorisation ISED n’est plus considérée comme valide et le numéro d’identification ID IC ne peut pas être apposé sur le produit final.
Dans ces circonstances, l’intégrateur OEM sera responsable de la réévaluation du produit final (y compris le transmetteur) et de l’ob-
tention d’une autorisation ISED distincte.
Étiquetage des produits finis
Les modules WGM160P sont étiquetés avec leur propre ID ISED. Si l’ID ISED n’est pas visible lorsque le module est intégré au sein
d’un autre produit, cet autre produit dans lequel le module est installé devra porter une étiquette faisant apparaitre la référence du mod-
ule intégré. Dans un tel cas, sur le produit final doit se trouver une étiquette aisément lisible sur laquelle figurent les informations sui-
vantes:
“
Contient le module transmetteur IC: 5123A-WGM160P
”
ou
“
Contient le circuit IC: 5123A-WGM160P”
L’intégrateur OEM doit être conscient qu’il ne doit pas fournir, dans le manuel d’utilisation, d’informations relatives à la façon d’installer
ou de d’enlever ce module RF ainsi que sur la procédure à suivre pour modifier les paramètres liés à la radio.

11.5 Locating
the Module Close to Human Body
When using the module in an application where the radio is located close to human body, the human RF exposure must be evaluated.
FCC, ISED, and CE all have different standards for evaluating the RF exposure, and because of this, each standard will require a differ-
ent minimum separation distance between the module and human body. Certification of WGM160P allows for the minimum separation
distances detailed in
Table 11.2 Minimum Separation Distances for SAR Evaluation Exemption on page 43
in portable use cases
(less than 20 cm from human body). The module is approved for the mobile use case (more than 20 cm) without any need for RF expo-
sure evaluation.

CE
The RF exposure must always be evaluated using the end-product when transmitting
with power levels higher than 20 mW = 13 dBm.
For FCC and ISED, using the module in end products where the separation distance is smaller than those listed above is allowed but
requires evaluation of the RF exposure in the final assembly and applying for a
Class 2 Permissive Change
or
Change of ID
to be
applied to the existing FCC/ISED approvals of the module. For CE, RF exposure must be evaluated using the end-product in all cases.
Note:
Placing the module in touch or very close to the human body will have a negative impact on the efficiency of the antenna thus
reducing range.
