Wi-Fi is the world's most popular wireless communications technology and is the most common way computers, tablets, smartphones and other devices connect to the internet. Instead of using wired connections like Ethernet, Wi-Fi uses radio waves to transmit information at specific frequencies, most typically at 2.4GHz and 5GHz. IEEE 802.11 defines the network technical standards for Wi-Fi networks, and devices looking to utilize Wi-Fi technology must adhere to these protocols.
How We Support Wi-Fi
In today's world, any smart product must be Wi-Fi compatible, along with being interoperable with other wireless technologies protocols like Bluetooth®, Matter and Zigbee. DSR has extensive experience with Wi-Fi technologies and can develop Wi-Fi solutions from scratch or enhance existing ones, providing services at each level of the solution.
In the past, we have productized Wi-Fi/Bluetooth® components, developed customer-specific Wi-Fi solutions, and customized Wi-Fi components to increase connectivity. From protocol implementation, and development of applications, middleware and device drivers, to utilizing our automated testing and certification tools, DSR is the ultimate partner to meet your Wi-Fi development needs.

Examples Of Work
Assisted in the implementation of the Bluetooth®/Wi-Fi middleware, which sat on top of the CSR stack, for the infotainment system in the 2014 Toyota Prius.
Implemented a Radar Detection feature for a Wi-Fi driver that changes device communication frequency when an operating weather or military radar is detected.
DSR developed a suite of automated testing tools for Wi-Fi silicon chipsets, including functional, performance, regression and certification testing for chipset vendors.
Developed the Wireless Access in Vehicular Environment (WAVE) stack to support Intelligent Transportation Systems applications that enables an exchange of data through a fast-moving connection between high-speed vehicles and an infrastructure network.
Partnered with Qualcomm to update the ath9k Wi-Fi driver to support OpenWRT in order to simultaneously connect to more devices, which was used in classrooms to connect students' Wi-Fi pens to a teacher's monitoring device.
Ported the Wi-Fi to Bluetooth® Low Energy Bridge application to support new hardware, developed Android and iOS provisioning applications and supported with full product testing.
Porting Tayo Yuden Wi-Fi/Bluetooth® module Linux drivers to Android OS, enabling communication between hardware and the OS.
Testing and improving the throughput of Wi-Fi Direct solutions for a partner company.
