Today all mobile devices like Smart Phones, Laptops, Tablets, and many more possess several wireless transceivers. However, many chips, their related circuits, and antennas consume a lot of space on already cluttered PCBs (printed circuit boards).
The Texas Instruments WiLink 8.0, a 45-nm chip solution, is composed of 15 different wireless chips including a minimum of 5 mixed radios that are generally used for Laptops, smart phones, tablets, and many other mobile devices. Including radios like Wi-Fi 802.11 a/b/g/n, ANT +, Bluetooth, GNSS (Global Navigation Satellite System), NFC (Near Field Communication), Bluetooth Low Energy, and FM Radios transmitters and receivers. Its flexible architecture and design supports any combinations of such technologies and customizations to achieve unique market needs in the mobile industry.
WiLink 8.0 chip comes in a compressed WSP (Wafer Scale Package) and can be affixed directly onto the PCB. It contains all necessary power management mechanism, RF front ends, and a complete parallel existence mechanism. WiLink 8.0 chip, at system level, reduces consumption of power by 30%, size by 45%, and cost by at least 60% in comparison to existing multiple chip designs.
WiLink 8.0 – Block Diagram:
Such devices utilize a variation of Wi-Fi bands, typically the 2x2 MIMO, 802.11 b/g/n, 802.11 a/b/g/n or 40 MHz single-stream bandwidth versions. Also, some forms can touch up to 100-Mbit/s or more Wi-Fi TCP traffic on 2.4 GHz and 5-GHz bands. WiLink 8.0 chips claims the fastest streaming experience and HD video capabilities and contains direct Wi-Fi with wireless display. These chips have very negligible latency rate, less power consumption, and offer software support from open sources as well.
WiLink 8.0 Chip – A Battery Saver:
Today, every Smartphone, Tablet or Laptop users are suffering from poor battery performance mainly because of continuous background activities performed by different embedded chips like Wi-Fi, Bluetooth, NFC, GPS, etc... Amongst all the greatness that smartphones offer, one significant let down remains constant and that’s the miserable battery life, whether its Android, Blackberry, or Windows-based devices. WiLink 8.0 helps boost battery life in big way due to its unique technology and design to include more than 5 radios into one single chip.
WiLink chips like WL189x, WL185x, WL187x, and WL183x comprise Bluetooth Low energy, Bluetooth, FM Radio receiver and transmit, and ANT+. Apart from this WL187x and WL189x also includes GNSS capability too. This dramatically helps reduce power consumption and host-independent.
The WL1185x and WL189x contain NFC radios too. These chips are the first of their kinds with a complete NFC controller solution. WiLink 8.0 chip’s NFC solutions are already paired and tested with the best secure technologies from leaders in the industry who specialize in the protection of NFC (digital wallet) transactions containing mobile payment, ticketing, access control, and electronic keys. The chip WL180x has only Wi-Fi which addresses low end mobile markets.WiLink 8.0 chip solutions are in sampling process with today’s top level mobile OEMs. Products bundled with WiLink 8.0 chips are expected to hit the market after June 2012.
