    Pandora Wi-Fi On 350kilobytes/s

    that's weird. I can scp files into my Freerunner over wifi (arm920t at 400MHz) at 800KB/s steady rate (about 1mbyte/s peak until cache gets filled). But that's severely clamped by two things: the multimedia chip (glamo) is between the CPU and the microSD card and it's MMIO is itself clamped to...

    Don't really know about windows. You'd need to set up a ram disk somehow. In linux you can just mount tmpfs wherever you want and you get this instant super fast low latency ram drive... Could you boot a linux live maybe ?

    I appreciate that very much. Thank you. EDIT: if you want to help with that or anything, hit me up

    I'm very sad that noone was capable of testing a local wifi link properly yet (no filesystem and internet bandwidth limit). I'm really interested in this. I hope it won't just fall into oblivion in this high traffic forum.

    Couldn't it be that the wifi speed is actually limited by SD write speed? Could anyone please try mounting tmpfs on pandora (mount -t tmpfs none /tmp/someplace) and wgeting a file inside of it ? Also, please do iwconfig <card> power off (disable power saving)

    Guess you're right.

    Except my pocket maybe.

    A powerhorse with 54mbit wifi clamped to 900KB/s (a 13% of theoretical maximum bandwith). EDIT: also, USB wifi doesn't consume anything when shut down if properly disconnected. And USB bluetooth HCI in Freerunner sinks about 20mA (3V) AFAIK. nothing compared to display backlight

    My point. Maybe pandora should've used USB-based chipset too. I gueseed the people knew what they were doing and it indeed was going to be what it is marketed as: a powerhorse. EDIT: sorry for double posting

    Fair enough. Touchbook is even more similar. I don't see N900 without a GSM inside and marketed as : '..a mixture between a PC and a gaming console..'

    Apparently so, mine does 12MB/s quite normally (ath5k). Well, looks like for once, I was incredibly lucky for a wifi card.

    Hi, thanks for your reply. Looks like you used a bad stick, the one in Touchbook gives a lot better performance (according to this: http://www.alwaysinnovating.com/wiki/index.php/Wifi it's rt3070 based). I hope the USB host in pandora itself isn't limited this way. And you can't really compare...

    OK looks like if wl1251_ps_set_mode hooks into wifi subsystem, power management is implemented. Could anyone with a pandora please post output of iwconfig ? EDIT: with the wifi connected to something, I forgot to add

    Nah, I do ARM hw design as well but just as a hobby (I just finished high school). I don't have enough money to get into making BGA chips on board so I was limited to ARM926EJ-S so far (the best one I found in TQFP). I think I know enough to know what's involved in transfering wireless frames...

    Is one month or so old really grave digging ? Ok sorry for not adhering to your rules then. I have been following pandora's site (and later developer blog too) since it was first announced. I considered it even before my Freerunner but I needed a phone too. I follow it a lot, just not the boards...
