WLAN Driver Development

Intelligraphics' Wireless team consistently provides technically innovative PC-based & embedded-based WLAN driver solutions. Whether you are planning to create a desktop client, AP, embedded Wireless-device, wireless-handset, PDA, SmartPhone, PocketPC or any other WiFi-enabled product, you can count on Intelligraphics’s WLAN team, which has developed wireless drivers for industry leaders like Atheros, Intel, Marvell, Conexant, TI and others,  to assist you with WiFi Driver/Firmware development to reduce the time-to-market.

We have vast experience with the Microsoft NDIS driver model (NDIS 5.x/6.x) for Windows platforms (Windows 2K/XP/Vista/Windows 7). In addition, our engineers have expertise and have provided various driver solutions in WLAN domain with support for wide variety of Operating-systems like all Windows-versions (Windows 2K/XP/Vista/Windows 7), Windows CE, Windows-Mobile( 5/6.x), Linux-variants (both PC-based and Embedded Linux like eCos, uCLinux) , Android, MacOS, VxWorks, PalmOS, Symbian and the Novell ODI driver models.

Intelligraphics is one of the first Authorized Atheros Design Center (AADC) partners. The Intelligraphics engineering team has members who have been working with Atheros WLAN chipsets since their inception in the late ’90s. Intelligraphics as a company has been doing WLAN development since early 2000.  Our WLAN driver development team is comprised of experienced engineers. They are recognized industry veterans with expertise in a wide variety of WLAN technologies, protocols and hardware devices.
                   

Being AADC partner of Atheros, our team has detail knowledge about Atheros WLAN chipsets and software-architectures of various Atheros’ code-bases. We have also provided WLAN driver solutions with other major WLAN-chip makers like Intel, Texas-Instruments (TI), Broadcom, Marvell and ZeroG. Our team has knowledge and expertise with various interface bus specifications like PCI, PCMCIA, PCCARD, Mini-PCI, USB, SDIO and other bus specifications.

 Intelligraphics’ development team has strong experience with 802.11 architectures and various WiFi standards IEEE 802.11 a/b/g/n and expertise of developing WiFi drivers for emerging WLAN standards like 802.11k. Intelligraphics can provide driver solutions, from driver development to high-level application and GUI development. Our team can develop support for Access Points (AP), WLAN NICs as well as WLAN Sniffer/Injectors. Our development expertise includes designing and developing wireless solutions that meet the industry specifications as well as enhancing existing drivers with value added features specified by our customers.

 

Our Expertise

Intelligraphics has been involved with 802.11 driver and firmware development since early 2000. Being AADC partner with Atheros, Intelligraphics can provide customization of the entire line of Atheros based WLAN devices (AR5002, AR5005, AR5006, AR5007, AR5008, AR9001, and AR9002).
Our Wireless team has the expertise to enhance base-drivers from Atheros, Intel, TI, Marvel and Broadcom to meet the specific needs of customers, such as:
