Strange signals....
(old news - 06:33PM Monday Dec 17 2007)
tags: wireless · trouble · networking
Network World says that Microsoft's Xbox 360 doesn't always play nice with neighboring wireless signals. According to the report, a troublesome signal is generated by the device's on-board 2.4GHz radio, which is used for the system's handheld wireless controller. The strange interference was first picked up by the IT staff at Morrisville State College:
During the fall, Morrisville IT staff, working with Meru engineers and IBM, the network integrator, detected an unusual signal in the 2.4GHz band. . . The Cognio software, however, was baffled by this new signal: "Unknown emitter" was the classification. The signal shows up in the Cognio display as a kind of green-blizzard effect, covering a large swath of the 2.4 band.
The signal continues transmission even when the game console is off. The interference can't be that disruptive, Given this hadn't shown up on anybody's radar until this far into the 360's life-cycle.

Re: Perhaps PS3 Fan Boys Striking?

Fanboys? Give me a break. I'm the one that is on his 3rd 360 from RRoD. I learned a lesson, M$ sells junk. Getting a PS3 has allowed me to enjoy (true, games are few for now) playing with friends and nephew while the 360 awaits shipping box and return (likely not till 3rd week of Jan).

So immediately, the 360 fanboys jump to "it's a PS3 conspiracy". Nice. Try putting a 2.5", 320GB sata drive in your 360. Even if you could, M$ would sell it at $400, require a special cable, and DRM the hell out of it.

For the long term investment, the PS3 is wise. The 360 has already gone to the Elite (for HDMI and deired black case) but where are the 65nm chips? And smaller GPU (Falcon board)
Meh. Keep your 360.

You don't need to purchase an Elite to have HDMI. I got the Premium bundle ($350), and it has HDMI output.

don't really care, but

One thing I find interesting is that it's still going when supposedly "off." I'd rather not be having ANY signals coming/going from the thing except standby power, which isn't much... laptops can survive in "standby" and do no such thing.

Personally, never seen this affect anyone I know w/a 360.

Re: don't really care, but

I believe this is because when in standby you can turn on the console with the controllers, thus the radio needs to be on.

As others stated, it's only off if you unplug it, other than that it is in standby, the signal is for connecting to controllers to wake it up.

I have a lot of 2.4 in my house no problems. It's interesting that the Morrisville folks initially discovered the problem when it affected their BT cell headsets, not the wifi.

Re: don't really care, but

That's because the Xbox controllers are also Bluetooth, I believe. As are the Wii's controllers and, if I had to guess, probably the PS3's wireless controllers as well. This might make sense that it would interfere with Bluetooth... but I thought Bluetooth did not operate on the 2.4 GHz spectrum? Can anybody confirm which frequency Bluetooth operates on?

Close. The Wii also uses bluetooth protocols. The PS3 and the Wii use the standard. The 360 uses a proprietary system.

The 360 controllers do not use Bluetooth, they use a use a proprietary wireless signal. Bluetooth is also in the 2.4Ghz range, it starts at 2.402Ghz and ends at 2.48Ghz.

For what its worth the Bluetooth hub for my HTPC sits right next to my 360 and I've never had a problem.

Yep it does interrupt other things

i have a dgl 4300 D-links. had it set on auto for channel selecting but now i have it set on channel 11. Haven't had any problems as of yet (have had a 360 since the 2nd week it came out). The only thing that i could notice before i switched the channel is my 360 controller wouldn't do anything at times, never did it interfere with my wireless Internet at all. this isn't a new problem, but then again were talking about IT people that don't play video games, that or there PS Fan-boys

EDIT: Its known that the battery will drain when the controller is off, MS even admitted this.

Happens in Wal-Mart with the Demo units also

There is a fix installed at Wal-Mart stores to turn off the Wireless Controller interface on the 360 units, because it interferes with their Handheld Scanner units. Microsoft has known about this, since the units hit the stores, even before consumers knew about it.

If I still had the memo when I did marketing for Marketsource, and it was not proprietary info, I would post same.

2.4ghz signals affect the 2.4ghz band?

You mean to tell me that a 2.4ghz signal is affecting the 2.4ghz band? Say it ain't so!

Next, you're gonna tell me that using a 2.4ghz cordless phone may affect my wireless-G connections. Pretty soon, I'll have to move my wireless router from the top of my microwave oven 'cause some idiot will claim that the oven emits 2.4ghz radio waves.

Some devices are more..polite..than others, hence why some cordless phones make the band nearly unusable, while others don't.

Re: 2.4ghz signals affect the 2.4ghz band?

Indeed. But one must remember, it is an unlicensed band; you can broadcast whatever you want on it, so long as it doesn't exceed X amount of power. Hell, microwave ovens emit up to 1500 watts of power, they just do it inside of a Faraday cage. I don't know for sure, but I'd bet the old Amana Radarange (a 20 year old microwave oven that puts out about 1500 watts) probably doesn't have the best of Faraday cages and leaks a bit, thus affecting Wi-Fi and 2.4 telephones.

Actually, you're wrong. It's licensed to Amateur Radio operators first.. We can run up to 1500 watts on the band, and all other non-licensed users must accept interference from licensed stations.

Amateur Radio operators can broadcast whatever they want as long as it's unencrypted and non-commercial on 2.4GHZ. I have read of AR ops who have setup long range WiFi links, quite interesting.

Unlicensed users are permitted to use either 1/2 watt or 1 watt depending on certain factors, I believe WiFi would fall under the 1 watt limit. I'm not sure exactly about all the limitations, but I do know that if you have am Amateur Radio license you can legally transmit up to 1500 watts as long as you identify your station every 10 minutes and transmit unencrypted signals. What "unencrypted" actually is, is not clearly defined. Theoretically, a ham could design a new method to encode / decode the data, and as long as no password or key is set, it is "unencrypted." Hams do this all the time with PSK31, Packet and other modes that the average person can't just "listen" in on... A long range (20+ mile) WiFi link could be listened in on, but if they were to develop another way to encode the data, it could be limited in use to only people who have the software to decode it.

But you must comply with not only part 97 rules you also have to make absolutly sure that the antenna is far away from all living things. No one would ever run 1.5kw on 2.4 and we can only use a select few channles. AND the #1 thing you all must remember running it as a HAM OP requires you to not allowing anything that violates part 97 such as commercial useage, (ads are commerical) and language must not include the 7 words. And you cannot hide the meaning of the message so you can't use lol, rofl etc since they hide the meaning with a acronam. So You are better off just to not run it as a ham op. AND if you do run it you must use the SSID of HMSS:yourcall HaM operator Spread Spectrum:callsign You also have to have your beacon (broadccasting SSID) So to me, I will use just what I got. No need to use power. UNLESS you really are tring to use your link 10 or more miles away. And if you're not careful you can get into trouble. So It is not worth it.

Crap Routers

I would be more concerned with the quality of the routers. The xbox is not the only thing that operates in this range and myself and everyone I have come into contact with the xbox has never had any issues. Many run a Wii next to their xbox and there are never any issues.

Polluted spectrum.

If you want to know what I think, I think the 2.4GHz spectrum is over-used and polluted.

What's sad is that the portions of the entire radio spectrum that are available to Mr and Mrs Everyone are very very limited.

On my Wi-Fi network the maximum I get here is 5mbps (802.11G) whereas at my old house I could get 22mbps. This is with the same equipment, and both tests were performed with the router just 3 feet from the laptop. Being that my area has a much higher population density than where I used to live, there's probably a whole whack of interference. Changing channels barely makes any difference...

What do you expect with unlicensed spectrum?

Well duh. 2.4 GHz is an unlicensed allocation. Devices operate their in an unlicensed free-for-all, per Part 15 of FCC Rules. Of course they're gonna interfere. Part 15 says any unlicensed device just has to put up with it. Don't like it? Only turn on one piece of equipment at a time.

Amateur Radio operators are the primary users on the 2.4ghz band, we can run up to 1500 watts legally.
What you're referring too is the allowance of unlicensed stations to operate under certain strict rules (power/antenna limitations).

Almost anything can screwup WiFi

Ok.. my sons x360 sits 10 feet from his PC which uses a USB WIFI adapter to connect to my router. I've never noted any issues with this set up. He uses his head set, no problem. Uses his wireless controllers, no problem. Only issue I've ever had with WIFI is my older 2.4ghz handsets, sitting at the PC, will sometimes knock it offline but once I locked in the routers channel. That problem is no longer a issue. I think that the conditions have to be just right if people are having problems but right now.. I'm on the fence and will lean towards tossing in the BS flag on this one.

Component changes can happen late in production

Component changes can happen late in the production cyclem both as oart of manufacturing cost reduction efforts and due to component availability. The components themselves can be changed for the same reasons by their manufacturers, and they won't tell Microsoft if they think they won't get caught (if they reduce the cost of the component they don't want to tell MS and have to share part of the savings).

So it is quite possible to have this sort of thing show up this late. It's not supposed to be functionally visible of course. especially when it's likely to draw FCC attention and regulatory action, but it can happen.

Who Are They Talking To?

From the article,

Barber says the signal seems be created by the console's embedded 2.4GHz radio, which is used to communicate with the handheld wireless controller -- the gizmo with the buttons that manipulate a game running on the console. The Xbox also takes an optional Wi-Fi adapter, in the form of an USB dongle, to connect to a WLAN access point.

Barber says his "best guess" at this point is that the embedded radio, not the USB adapter, causes the signal. The signal is created even if the Xbox console is shut off: Just plugging its AC adapter into an electrical outlet seems to trigger the radio to look for -- and keep looking for -- a companion wireless controller. "It’s even worse when you have multiple Xboxes in an area," Barber says.


Who is the target audience here? Retards? Best guess? DUH! What a crap article.
