Marvell Avastar 88W8897: Wifi 802.11ac, NFC and Bluetooth 4.0 Chip

Marvell has announced the Avastar 88W8897, a low-power radio chip supporting 802.11ac, near field communication (NFC) and Bluetooth 4.0, aimed at mobile and HD multimedia devices such as ultrabooks, tablets, gaming consoles and smart TVs. Marvell claims the 88W8897 SoC enables a rest of bill of materials (RBOM) footprint reduction of 40-to-50 percent and cost reduction of 75 percent compared to previous wireless solutions. Key features of Marvell Avastar 88W8897 chip include: Wi-Fi 802.11ac – This standard increases bandwidth available over the Wi-Fi link (theoretically up to 1 Gb/s) with throughput up to 867 Mbps for the 88W8897. This kind of throughput allows reliable high-definition (HD) video streaming, tunneled direct link setup (TDLS) and high-speed wireless backup and sync for mobile devices. NFC – NFC allows consumers to pay for items with the tap of a phone via mobile commerce and point-of-sale (e-wallet) applications. It can also enable one-tap pairing […]

Linaro 12.02 Release with Kernel 3.3-rc

Linaro has just released version 12.02 based on Linux Kernel 3.3-rc and Android 4.0.3. Among the key points, they have started to work on Freescale i.MX6 SabreLite board, included libav 0.8 to Ubuntu images which provides up to 160% performance improvement while playing real-media videos and XBMC is available via PPA. Here are the highlights of the release: Android Linaro Android can now be built with current GCC 4.7 snapshots. A 4.7 based toolchain build preview is also available. Linaro Android can boot on iMX6 Sabrelite boards. All test result spreadsheets have been streamlined and are now easier to use. Bluetooth enablement have been completed for the Origen board. A Prototype of using camera on Snowball was made. Presentations Given by Linaro Android Team this cycle “Binary Blobs Attack!!!” – Embedded Linux Conference. “What Android and Embedded Linux can learn from each other” – Embedded Linux Conference. “Integrating Projects Using […]

Using NFC for Bluetooth Pairing

The NFC Forum and the Bluetooth Special Interest Group (SIG) announced the publication of Bluetooth Secure Simple Pairing Using NFC. This new document provides developers with examples of how to implement Bluetooth Secure Simple Pairing (SSP) using NFC to take maximum advantage of both technologies when they are present in the same device. Bluetooth Secure Simple Pairing Using NFC describes the interaction of Bluetooth technology and NFC during SSP in details and provides examples of both negotiated and static handover in the most feasible use cases involving both technologies. Developers will find the examples useful guides for their own work, including: Pairing devices with little or no user interface (such as headsets and pedometers) to smartphones Pairing devices with extensive user interfaces (such as cars) to smartphones Pairing devices such as TVs and smartphones to share photos or to use the phone as a remote control While studying about this […]

List of Wireless Standards for Local and Personal Area Networks

While designing your embedded system, you may have to choose between different wireless standards to match your needs. I’ll provide a list a short and mid-range wireless standards, their description and links to open source software stacks (when available) to help you better understand the different options available. Wide Area Network wireless network such as LTE, Wimax, etc.. won’t be discussed in this blog entry. Mesh and IP Networks: Wifi (IEEE 802.11): Wifi is probably the most used wireless standard in consumer electronics devices today as it allows users to connect their device to their LAN wirelessly. An access point has a typical range of about 20 meters indoors and up to 100m outdoors. There are 4 standards 802.11a 802.11b, 802.11g and 802.11n. The latest has a theoretical throughput of 300 Mbps. Check out Wikipedia Wifi page for details. The Wi-Fi stack is part of the Linux kernel but you […]
