Wireless Bridge Communications Subsystem
The Laird WB45NBT provides complete enterprise-class Wi-Fi connectivity with an integrated TCP/IP stack, full support for IEEE 802.11a/b/g/n and Bluetooth 4.0 dual-mode air standards with a fully integrated security supplicant providing 802.11i/WPA2 Enterprise authentication, data encryption, and BT protocol stacks.
The WB45NBT has a wide variety of interfaces including Fast Ethernet, serial UART, Hi-Speed USB, SPI, and I2C. The wireless bridge may be configured, monitored, and managed via a Command Line Interface (CLI) over an available dedicated console port, via a web interface over a wireless or Ethernet interface, or via a remote SDK interface over wireless or Ethernet.
The WB45NBT incorporates a Wi-Fi SiP module using Qualcomm Atheros AR6003 which supports IEEE 802.11a/b/g/n. The CSR (CSR8510) Bluetooth chip supports Bluetooth standard 4.0 which includes the Bluetooth Low Energy (BLE) and legacy modes. The product features an ARM9 processor running at 400 MHz, 64 MB of Lower Power DDR (LPDDR) memory, and 128 MB of NAND flash storage running at 1.8 V to minimize power consumption. Several GPIO lines are available for data acquisition and similar applications. The platform runs an embedded Linux operating system based on the 3.x kernel. A Software Developer’s Kit (SDK) with Application Programming Interfaces (API) and software tools are available for the development of custom software applications on the device.
The WB45NBT measures 40 mm long by 40 mm wide by 3.8 mm thick. The wireless bridge physically interfaces to the host device via an 80 pin board to board (B2B) connector (Molex SlimStack™ 54722 Series 80 Pin Connector P/N 54722-0804), which mates to a 1.5 mm stacking height mating part from Molex 55560 Series P/N 55560-0804. The WB45NBT may be secured to the host device via available grounded mounting holes. The WB45NBT operates at temperatures between -20° and + 70° degrees Celsius.
Contingent on compliance results, WB45NBT is a fully integrated module. It has its own RF shielding and does not require shielding provided by the host device into which it is installed in order to maintain compliance with applicable regulatory standards. As such, the device may be tested in a standalone configuration via a breakout board (SDC-BB45NBT).
The WB45NBT provides three U.FL type antenna connectors; the Main antenna (for Wi-Fi) and the Auxiliary (for Bluetooth) work separately to get the best coexistence performance. A third antenna connector multiplexes both the Wi-Fi and the Bluetooth signals into a single RF port through the use of a T/R switch however, this mode of operation is currently not supported. Supported host device antenna types include dipole and monopole antennas.
Regulatory operational requirements are included in this document and may be incorporated into the operating manual of any device into which the WB45NBT is installed. The WB45NBT is designed for installation into mobile devices which typically operate at distances greater than 20 cm from the human body and portable devices which typically operate at distances less than 20 cm from the human body.
The WB45NBT is certified as compliant with ETSI, FCC, and IC standards in addition to its Wi-Fi certification. CCX compliance and Bluetooth SIG Qualification are pending. Laird customers can leverage our grants, approvals, and formal test reports to achieve their required device certifications. The degree to which customers can leverage our certifications is dependent upon the regulatory agency, industry body, and the type of end device.
If any additional information or assistance is required, please contact the Laird wireless certifications group via email or visit our Technical Support Center.
The WB45NBT is compliant to various CE and ETSI standards and specifications:
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 WB45NBT is fully compliant with Annex IV procedures in article 10.5 of R&TTE directive 99/5/EC.
Like all Laird Wi-Fi modules, the WB45NBT is fully compliant with European Union Directive 2011/65/EU or Reduction of Hazardous Substances (RoHS) and Registration, Evaluation, Authorization, and Restriction of Chemicals (REACH) as per our Declaration of Compliance.
Laird has received the following FCC grants for the WB45NBT(FCC Identifier: SQG-WB45NBT).
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.
These 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 the following antennas:
Note: When using this grant, the WB45NBT must be installed only in mobile devices. Mobile devices are devices which typically operate at distances greater than 20 cm (7.9 inches) from the human body. When certifying portable devices (those that typically operate at distances less than 20 cm from the human body), a new grant must be secured by the device vendor.
The WB45NBT is certified to the Industry Canada (IC) RSS-210 standard. IC 3147A-WB45NBT certification is based on FCC certification testing, using the same antennas and transmit power and covering the same frequency bands. The IC grant and test reports relevant to this certification may be found below:
Laird has secured the following MIC certification:
The following test reports in support of the MIC certifications are available:
Laird has received the following Korea Certification grant (with its associated test report):
Laird has submitted the WB45NBT 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 WB45NBT, 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 Summit-equipped devices.
