Is it mandatory to have broadcast receiver as a separate file?

Can I buy a usb wireless broadcast and receiver dongle pair?

  • I am looking to get a new car stereo/video/mp3 player. It has a USB-connection. I want to buy a dongle to broadcast what the stereo is currently playing to be picked up by screens/tablets whatever that I want to install on the back of the driver and passenger seats. Say iPads for the sake of argument but I might go for other devices. So I am looking for a usb dongle 'broadcaster' and a pair of usb dongle 'receivers' that will handle the connectivity. Do these exist? {EDIT] this is the stereo I'm looking at: http://www.halfords.ie/webapp/wcs/stores/servlet/product_storeId_11101_catalogId_15551_productId_730003_langId_-1_categoryId_212562

  • Answer:

    Not yet (or at least not with good UX), so I think this is a startup opportunity for someone. As a computer engineer I can tell you that one of those could be 2 cm x 2 cm x 10 cm and have 3 hours battery life, using an ARM processor, a USB battery charger and undervolt cut out chip, and a Wifi Direct radio with front-end and baseband. Total of maybe $12 of electrical components, plus PCB fab and PCBA (expensive protos but dirt cheap in volume > 10k units), and a case design which can be 3D printed or aluminum. They would have fixed IP addresses (so no DHCP server needed) selectable by the user using a hardware dial with 2 to 8 "channel options". They would be recharged using the USB power standard through that same port when it connects to something that can power it (a host or a battery pack). They could also comply with the Qi wireless power standard, in both directions of being charged and chargin. The USB data connections would be bidirectional, letting the host be on either side, and supporting USB OTG as well as regular USB. They could operate near 5 GHz to avoid the traffic congestion on 2.4 GHz these days (Dec 2012)

I've been looking -- so far the most direct wireless solution I've found is this: http://www.everythingusb.com/cables-unlimited-wireless-usb-adapter-kit-15823.html I believe NetGear makes (made?) something similar.  Not being very savvy in this WUSB arena, I haven't found a simple answer that satisfies me. Perhaps someone here can expand?
