Certifications Cisco_Compatible_35x30 Cisco Compatible Extensions (Version 4)
Warranty Limited Lifetime 

All specifications are subject to change without notice 

The CF10G is certified for compliance to various ETSI, FCC, and MIC (formerly TELEC) standards, as well as Wi-Fi Alliance and Cisco Compatible Extensions (CCX) specifications. These grants, approvals and formal test reports may be leveraged by Laird customers to achieve their required device certifications.

The degree to which customers can leverage these Laird items is dependent upon the regulatory agency, industry body and the type of end device. If additional information or guidance is required, please contact our certifications group via email or by telephone at 330.434.7929.


Laird has secured certifications for the CF10G to the following ETSI standards:

These certifications were secured with the following configurations:

  • CF10G with a transmit power of 17 dBm with a 2.2 dBi dipole antenna
  • * CF10G with a transmit power of 18 dBm with a 0 dBi PCB omnidirectional antenna

Any of these certifications may be leveraged by mobile and portable device vendors as part of their self declaration to obtain the CE mark required by members of the European Union. ETSI/CE rules differ from those of the FCC and IC in that there is no provision for a modular approval. All approvals and certifications must exist at the device, rather than the radio module, level.

Laird has obtained a Frequency Authority Certificate for the CF10G in compliance with Annex IV procedures in article 10.5 of R&TTE directive 99/5/EC. Like all Laird devices, the CF10G is fully compliant with European Union Directive 2003/95/EC or Reduction of Hazardous Substances (RoHS) and Registration, Evaluation, Authorization, and Restriction of Chemicals (REACH) as per our Declaration of Compliance.

Laird 10- and 20-Series EN 300 328 v1.8.1 Updates

EN 300 328 v.1.8.1, which officially goes into effect on January 2015, includes new mandatory spectrum sharing requirements with the goal of reducing interference within the 2.4 GHz band. The following are the two main ways to achieve this: 

  • By incorporating adaptivity functionality such as DAA (Detect and Avoid), CCA (Clear Channel Assessment), and LBT (Listen Before Talk) 
  • By reducing the radio’s power, duty cycle, or both The 10-series and 20-series radios rely on the Broadcom BCM4318 chip.

Due to this, these radios have issues with the CCA aspects of spectrum sharing. Although we have received a Declaration of Conformity for the BCM4318, this is the extent of the assistance we have received from Broadcom. Despite repeated requests to Broadcom over the past 12 months, we have not received test reports that support this compliance or firmware updates to fix the CCA issues.

Given the above, our customers with these products currently have the following options: 


Laird has received the following grants for the CF10G:

Part 15 Subparts B (Class B), section 1.1310 (RF Exposure), and Part 15 Subpart C Section 15.247 a, b, d, and e. 

Class II Permissive Change

All above testing for the TWG-SDCCF10G grant was performed with the CF10G configured for 18 dBm (63 mW) transmit power. The following antennas were used during testing for the initial grant:

  • 2.2 dBi Dipole (whip or "rubber duck") antenna to result in an Effective Isotropic Radiated Power (EIRP, or the combined gain of the transmitter and antenna) of 20.2 dBm
  • 0 dBi Printed Circuit Board Omnidirectional antenna for an EIRP of 18 dBm

Subsequently, the following antennas were used for the Class II Permissive change addition:

  • 5 dBi Dipole (whip or "rubber duck") antenna to for an EIRP of 23 dBm
  • 2 dBi Printed Circuit Board Omnidirectional antenna for an EIRP of 20 dBm

Data sheets for the above antennas are available upon request by contacting the Laird certification group.

This grant is a Limited Modular Approval (LMA). Specific limitations are indicated on the grant:

  • The CF10G must be installed by an Original Equipment Manufacturer (OEM) such as a Portable Data Terminal vendor.
  • When using this grant, the CF10G must be installed only in mobile devices (devices which typically operate at distances greater than 20cm, or 7.9 inches, from the human body). When certifying portable devices (those that typically operate at distances less than 20cm from the human body) a new grant must be secured by the device vendor.

Note: Laird test data may be leveraged by the device vendor to minimize the cost and time associated with the certification process.

Industry Canada

Laird has secured an Industry Canada (IC) RSS-210 Certification based upon the FCC TWG-SDCCF10G grant. As such, this certification is applicable to mobile devices when using the CF10G set to 18 dBm transmit power with antennas as per the above. The initial grant is based on testing using the 0dBi PCB omnidirectional and 2 dBi dipole antennas while the subsequent grant was based on testing using the 2dBi PCB omnidirectional and 5 dBi dipole antennas. RSS-210 certifications for portable devices may be similarly leveraged from device-level FCC grants for portable devices as per the above.

MIC (formerly TELEC)

Laird has secured two MIC certifications to the following standards: RCR STD 33, ARIB STD T66, and ARIB STD T71.

Certification - Channels 1-13

Certification - Channel 14

These certifications were secured power with a power setting of 17 dBm (50mW) with a 2.2 dBi dipole antenna and a 0 dBi PCB omnidirectional antenna. As with Laird's ETSI certifications, device vendors may leverage this certification and the associated test reports when applying for MIC certifications at the device level.

Wi-Fi Alliance

Laird has submitted the CF10G to an authorized Wi-Fi Alliance test lab and as a result has received an Embedded Client Certification to the following standards: 802.11b, 802.11g, WPA (both personal and enterprise) and WPA2/802.11i (both personal and enterprise). For those host devices which include the CF10G and are using version 1.02.04 of the Summit Client Utility (SCU) and 1.02.05 of the device driver (or later versions of each), the vendor may assert that their device incorporates a Wi-Fi Certified Embedded Client. The vendor need not be a member of the Wi-Fi Alliance to make this assertion but may not use the "Wi-Fi Certified" logo in conjunction with their device.

If the device vendor is a member of the Wi-Fi Alliance, they may have WFA certification transferred to them only if they integrate the already-certified module into their device in a "hands off" manner; in other words, make no changes during integration that would impact the way in which the module operates. Laird will provide consultative services to those vendors who choose to pursue a Wi-Fi Alliance certification for their Laird Wi-Fi equipped devices.

Cisco Compatible Extensions

Laird is a member of the Cisco Compatible Extensions (CCX) program and has a direct license from Cisco for intellectual property relating to the various versions of the CCX specifications. Laird has submitted the CF10G to an authorized CCX test lab and has been found to be fully compliant with version 4 of the CCX specifications for application specific devices (ASDs). For those host devices which include the CF10G and are using version 1.02.08 of the Summit Client Utility (SCU) and device driver (or later versions of each), the vendor may assert that their device incorporates a Cisco Compatible radio module.

Device vendors who are members of the CCX program may also choose to secure CCX compliance for their end device. When incorporating the CF10G into their product with the above software version, the vendor need not be a direct licensee for Cisco intellectual property. Rather, in this case the device vendor need only submit their CF10G enabled device for CCX compliance testing to the version 4 test plan for ASDs. By leveraging Laird's "pre-approved" Wi-Fi software and by testing to the same plan, the vendor has a greater assurance that their actual testing will result in an end device compliance. Laird will provide consultative services to those vendors who choose to pursue CCX compliance for their Laird Wi-Fi equipped devices.
