When designing a Wi-Fi product, it’s important to keep in mind what channel set you want your product to use because each country allows and disallows different channels for various Wi-Fi operations. In other words, channels that are supported depend on the regulation in each country. Here is a summary of most countries:
In April, ETSI announced new mandatory spectrum sharing requirements for the 2.4 GHz band which will take effect January 2015. Laird’s MSD30AG/SSD30AG, 40NBT Series, WB45NBT, and MSD45N/SSD45N, have all been successfully tested to the new standard. The following is the status on the 10, 20, and 15 series radios:
Laird 10- and 20- Series EN […]
As a result of the growing number of innovative devices equipped with wireless technologies such as Wi-Fi, Bluetooth, and Zigbee coming to market, the European Telecommunications Standards Institute (ETSI) has updated two GHz band standards. Mandatory for market access in Europe, the standards updates are set to take effect in January 2015.
ETSI EN 300 […]
Recently, Network World published an article titled “Old-school Wi-Fi is Slowing Down Networks, Cisco Says”. The article goes into detail about two Cisco engineers who are proposing standards changes to scale down unnecessary traffic to Wi-Fi channels. According to the article, the early Wi-Fi standards that first made wire-free networking a […]

IEEE 802.15.4 is a standard developed by the IEEE to enable low power, mesh networks. It has seen tremendous use for SCADA, Wireless Sensor Networks, Industrial controls and other industries due to its ability to enable low-power sensing and controlling. 802.15.4 is also the physical layer […]
Embedded Wireless Solutions of Laird recently announced the release of the CL024 transceiver. The CL024 transceiver is a Frequency Hopping Spread Spectrum (FHSS) radio designed for license-free operation in the 2.4 GHz Industrial, Scientific, and Medical (ISM) band.
The CL024’s use of Frequency Hopping Spread technology is significantly beneficial. It enables multiple networks to co-exist in […]
A recent online editorial from Lisa Phifer argues that enterprise Wi-Fi deployments should focus on the 5 GHz band. According to Phifer, the current 2.4 GHz band is so congested with Wi-Fi, Bluetooth, Zigbee, and other interferers that it no longer serves its purpose. As a result, many device manufacturers are looking to […]
The Connectivity Products Business Unit (CPBU) engineering team has produced a C Library that enables embedded engineers to create software to communicate efficiently with the RM024 platform. The C Library includes several examples for utilizing basic AT commands as well as more advanced commands for reading and writing the RM024 EEPROM and for performing RM024 […]
During the development of our latest RAMP module, the RM024, we broke out of our florescent-lit Kansas office to enjoy some of the nice weather and put our new RAMP module, the RM024, through its paces. Specifically we wanted to do some real-world range testing and compare the RM024 with the LT2510, which it will […]
TV White Space has been called beachfront property as it represents the first new frequencies available for unlicensed use in some time. The frequencies are becoming available because the guard bands necessary for analog television transmission are no longer needed with digital TV transmissions.
It’s not all good news for the users of the unlicensed […]
