That is strange. They both run on 2.4 GHz. But the NZ90 can use BT and WiFi. |

Actually, cbulock, since you've just demonstrated an inability to grasp basic logic, you must be implicitly asking for YOUR count to be taken to zero.
The point is that they're dog-piling on and abusing the guy... and there's a history of that behavior with no apologies or repercussions when the messenger they've stoned turned out to be right. Why are you condoning that behavior, and how did you make it up to Ayasin after it happened to him? Or did you view "Lord of the Flies" as the second volume of "How To Make Friends and Influence People"? |
...and attacking the people who attack people doesn't exactly strengthen your position. Suggesting that the person can't grasp basic logic (though I don't know what specific principle of logic you're referring to) is little more than an insult. Had you simply stated your observation without the sarcasm at the beginning and end of your post, you could have conveyed the same message without drawing suspicion of hypocrisy. On a side note, I believe that Lord of the Flies is a much more accurate reflection of human nature than How to Make Friends and Influence People (or as I like to call it, "How to Deceive People into Believing You Are Someone That You're Not). | |

| My PowerBook G4 has both Bluetooth and WiFi (802.11b & g) and I find that if I'm on the outer perimeter of my range to the WiFi base station, AND I have Bluetooth on, there is interference. If I have a good signal for the WiFi, I find the Bluetooth doesn't interfere... at least not noticeably. | |

| that is totally fake.
the name is fake, also stuff like 48mb rom.
he's just come up with all the cool sounding features we would all like | |

And you really shouldn't be insulting people especially when the only facts that you have are from some totally anoynomus source. This could be true, but its like me coming on here as a guest, saying a have proof that pigs can fly, and then you calling people mindless losers because they don't believe it. |
The point you didn't notice is that those specs are possible and they could be done, while making pigs fly (on their own) would require a catapult, which are nowadays on short supply... | |

| Boy this thread got a little nasty there for a bit! Come on guys, we can do better. If this is a false rumor the guy is probably sitting back LHAO at us for bickering about nothing. Probably his intentions when he started this. | |

| so much bull, so little substance..........
this again brings us to the much debated topic...should unregistered users be allowed to post replys.
Much of the garbage gets posted by unregistered users....
and the start of this thread has its origins from on of them!

Nevermind...Im sitting here with BT, WiFI and a 2.4Ghz cordless phone. No interference | |

BT and WiFi should not cause interference witheachother or with corless phones. 2.4 Ghz BAND of radio frequencies from >2.3 Ghz to <2.5 ghz. There are multiple carrier waves within this spectrum which allow BT and WiFi to use the same frequency with little direct interference. It's the same as flying RC airplanes on different channels. All RC planes fly on a CHANNEL of the 72 mhz frequency band but do not interfere with each other because the receivers are narrow band receivers. If Sony has done its R&D properly, there negligable interference with the BT and WiFi devices. You’d be more likely to experience interference from oscillations in power lines outside your house than from a low power output Bluetooth device | |

There are multiple carrier waves within this spectrum which allow BT and WiFi to use the same frequency with little direct interference. | The important missing piece from your assumption is, how do they work?
Bluetooth automatically and somewhat randomly hops around the spectrum, tries a transmission, and if it fails (no ack), hops again. Cordless phones work this way too. WiFi looks for a clear channel first. But both 802.11b and Bluetooth have validity checks resulting in retries, so the result is speed degradation when sending data, not garbled data in the classic "interference" definition, and it impacts WiFi more because it takes longer to select a channel and because Bluetooth stomps on WiFi more than vice-versa.
The other form of interference that's relevant is entirely due to the antenna and wavelengths. That's more relevant to handhelds than to other devices. Basically each transmitter antenna causes severe distortion to other transmitter antennae inside a certain area based on the wavelenth. My physics is a bit rusty (although it was my degree), but I believe the number I ran across in some documentation was about six inches. One wavelength would be 0.125 meters roughly, or just under five inches, so that measurement does pass my sniff test.
So a fun experiment would be to have full-speeds tests bluetooth to bluetooth and WiFi to WiFi, ... moving a BT to one WiFi within an inch or so, and see if the effective speed of either degrades at all. | |
