## **WGM160P Wi-Fi[®] Module Data Sheet** 

The WGM160P is an ultra low power all-inclusive Wi-Fi[®] module targeted for applications requiring excellent RF performance, low power consumption, high security, integrated customer applications and fast time to market. 

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. 

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 dedicated to processing the customer application tasks. The WGM160P module has highly flexible host and peripheral hardware interfaces for wide application use.

WGM160P Wi-Fi[®] 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 reliability. 

## **5.2  Multi-Protocol Co-Existance** 

Packet Transmit Arbitration (PTA) pins are provide to share antenna and optimize co-existence performance with other networks including other protocols. See Application Notes "AN1128 Bluetooth Coexistance with Wi-Fi" and "AN1017 Zigbee and Thread Coexistance with Wi-Fi" for more information.

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.

WGM160P Wi-Fi[®] Module Data Sheet Soldering Recommendations 

## **9.  Soldering Recommendations** 

The WGM160P is compatible with industrial standard reflow profile for Pb-free solders. The reflow profile used is dependent on the thermal mass of the entire populated PCB, heat transfer efficiency of the oven, and particular type of solder paste used. 

- Refer to technical documentations of particular solder paste for profile configurations. 

- Avoid using more than two reflow cycles. 

- Aperture size of the stencil should be 1:1 with the pad size. 

- A no-clean, type-3 solder paste is recommended. 

- For further recommendation, please refer to the JEDEC/IPC J-STD-020, IPC-SM-782 and IPC 7351 guidelines. 

- Above notes and stencil design are shared as recommendations only. A customer or user may find it necessary to use different parameters and fine tune their SMT process as required for their application and tooling.

## **11.  Certifications** 

This section details certification status of the module in various regions. 

The manufacturer address for the modules is: 

Silicon Labs International 18 Tai Seng #05-01 18 Tai Seng Street Singapore 539775 

## **11.1  Qualified 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 that is of the same general type and of equal or less directional gain as listed in the above table can be used without a need for retesting in the regulatory areas that have a full modular radio approval (USA, Canada, Korea, Japan). 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 manufacturer 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 (DoC) is available via https://www.silabs.com/products/wireless/wi-fi/wgm160p-wifi-module.

## **ISEDC (Français)** 

Industrie Canada a approuvé l’utilisation de cet émetteur radio (IC: 5123A-WGM160P) en conjonction avec des antennes de type dipolaire à 2.14dBi ou des antennes embarquées, intégrée au produit. L’utilisation de tout autre type d’antenne avec ce composant est proscrite. 

Ce composant est conforme aux normes RSS, exonérées de licence d'Industrie Canada. Son mode de fonctionnement est soumis aux deux conditions suivantes: 

1. Ce composant ne doit pas générer d’interférences. 

2. Ce composant doit pouvoir est soumis à tout type de perturbation y compris celle pouvant nuire à son bon fonctionnement. 

**Déclaration d'exposition RF** 

L'exception tirée des limites courantes d'évaluation SAR est donnée dans le document RSS-102 Issue 5. 

Les modules WGM160P22A and WGM160P22N répondent aux exigences requises lorsque la distance minimale de séparation avec le corps humain est de 30 mm. 

La déclaration d’exposition RF ou l'évaluation SAR 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 SAR. 

## **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 conditions 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. Cependant, il incombe à l’intégrateur OEM de s’assurer de la bonne conformité du produit fini avec les autres normes auxquelles il pourrait être soumis de fait de l’utilisation de ce module (par exemple, les émissions des périphériques numériques, les exigences de périphériques PC, etc.). 

## **REMARQUE IMPORTANTE** 

ans le cas où ces conditions ne peuvent être satisfaites (pour certaines configurations ou co-implantation avec un autre émetteur), l'autorisation ISEDC 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'obtention d'une autorisation ISEDC distincte. 

## **Étiquetage des produits finis** 

Les modules WGM160P sont étiquetés avec leur propre ID IC. Si l'ID IC 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 les référence du module intégré. Dans un tel cas, sur le produit final doit se trouver une étiquette aisément lisible sur laquelle figurent les informations suivantes: 

## “ **Contient le module transmetteur: 5123A-WGM160P** ” 

## or 

## “ **Contient le circuit: 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.

WGM160P Wi-Fi[®] Module Data Sheet Certifications 

## **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, IC, and CE all have different standards for evaluating the RF exposure, and because of this, each standard will require a different 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 41 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 exposure evaluation. 

**Table 11.2.  Minimum Separation Distances for SAR Evaluation Exemption** 

|**Certification**|**WGM160P with integrated antenna**|**WGM160P with external reference dipole**<br>**antenna**|
|---|---|---|
|FCC|24 mm|24 mm|
|ISED|30 mm|30 mm|
|CE|The RF exposure must always be evaluated using the end-product when transmitting<br>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.
