802.11a/b/g/n and Bluetooth 2.1 Device Server Module
The SDC-WB40NBT is a Wi-Fi and Bluetooth Device Server module that supports 802.11a/b/g/n and Bluetooth 2.1. The module is a complete wireless communications subsystem that may be integrated into a variety of host devices via a number of available electronic and logical interfaces including UART, SPI, SDIO and Ethernet. Incorporating the Summit SDC-SSD40NBT radio, the WB40NBT provides all of Summit's hardware and software capabilities including dual band antenna diversity, an expanded operating temperature range, a fully integrated software suite and advanced Wi-Fi/Bluetooth coexistence. The module features a fully integrated IP stack and web server running on a Linux 3.0 kernel and may be accessed via a provided command line or browser interface for easy configuration and monitoring.
Please review the Hardware Integration Guide for complete device specifications.

The SDC-WB40NBT is certified for compliance to various CE, ETSI, FCC, Industry Canada, and Wi-Fi Alliance standards. Certification to MIC standards and Cisco Compatible Extensions (CCX) specifications are planned for the near term. The grants, approvals, and formal test reports associated with these certifications may be leveraged by Summit customers to achieve their required device certifications. The degree to which customers can leverage these Summit items is dependent upon the regulatory agency, industry body, and the type of end device.
If any additional information or guidance is required, please contact Summit's certification group via email or by telephone at 330.434.7929.
The SDC-WB40NBT has been tested for compliance to various CE and ETSI standards and specifications:
- EN 300 328 (Wi-Fi)
- EN 300 328 v1.7.1 (BT 2.1)
- EN 301 489
- EN 301 893
- EN 55022:2010 (Class B)
This testing was conducted with the following antennas:
These formal test reports 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 level rather than the module (radio) level.
The SDC-WB40NBT is fully compliant with Annex IV procedures in article 10.5 of R&TTE directive 99/5/EC.
Like all Summit devices, the SDC-WB40NBT is fully compliant with European Union Directive 2011/65/EU or Reduction of Hazardous Substances (RoHS) as per our Declaration of Compliance.
Summit has received the following FCC grants for the SDC-WB40NBT (FCC identifier TWG-SDCWB40NBT):
FCC Part 15.247 Subpart C
This grant relates to operation in the 2.412 to 2.462 GHz (ISM) and 5.745 to 5.805 GHz (UNII-3) frequency bands.
FCC Part 15.407 Subpart E
This grant relates to operation in the 5.180 to 5.240 GHz (UNII-1), 5.280 to 5.320 GHz (UNII-2), and 5.500 to 5.700 GHz (UNII-2 Extended) frequency bands.
These grants were secured with two dual band antennas:
The above grants are Modular Approvals. Specific limitations are indicated on each grant.
When using this grant, the SDC-WB40NBT 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: Summit test data may be leveraged by the device vendor to minimize the cost and time associated with the certification process.
The SDC-WB40NBT is certified to the Industry Canada (IC) RSS-210 standard. IC 6616A-SDCWB40NBT certification is based on FCC certification testing, using the same antennas and transmit power and covering the same frequency bands. Test reports and data sheets relevant to this certification may be found in the FCC section above.
The SDC-WB40NBT (NCC ID CCAB12LP1330T6) is certified to the National Communications Commission (NCC) standards:
The SDC-WB40NBT is certified to the following Australian/New Zealand standard:
Summit has submitted the SDC-WB40NBT to an authorized Wi-Fi Alliance test lab and as a result has received an Embedded Client Certification for the following standards: 802.11a, 802.11b, 802.11g, WPA (both personal and enterprise), and WPA2/802.11i (both personal and enterprise). For those host devices which include the SDC-WB40NBT, 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. Summit will provide consultative services to those vendors who choose to pursue a Wi-Fi Alliance certification for their Summit-equipped devices.
