Wifi speeds on P1i. |

Just wondering what speeds you guys have experienced with wifi on P1i. I have been finding it very slow and checked it with a speed test online on several different times. I wasn't expecting the 5-6 mb/s speed i get on my pc but my last wifi phone (wm5) was averaging 1.5 mb/s. My P1i is averaging about 150Kb/s which is no better than 3g. This is sitting right in front of a router on a 8mb/s line. I have double checked P1i is actually using wifi & not GPRS connection. Just thought it strange. Is this what I should expect from the phone? Any thoughts appreciated. |

P1i only supports wifi b which means the max it can recieve is 11mbps; not the 54 mbps that you would get with G. But indeed, such a low speed is odd. |

Yeah whats up with that whole b but not g thing. That sucks, they didnt even upgrade that on the W960. |

But W960 doesn't have this bug. I'm getting full speeds on my W960 when using WLAN.

I can only repeat the question of why you want a 56mbps wifi capability in your phone when the average broadband probably only has an 8mbps connection with your service provider?
but the issue of b and not g in P1 is not the question here and I am certainly acheiving higher speeds than mentioned here

Agreed. There's absolutely no need for downloading speeds above 11 Mbit/s on a mobile phone.

Doesn't really matter whether it's wifi b or g as far as internet is concerned does it? Unless someone has a connection running at over 11mbps? I'd quite like to get a 1/10th of that on my p1i! |

Do you have wifi power save turned on? |

Check power saving but also a bluetooth device working in the vincinity (10m) as BT is well known for degrading WiFi performance. |

Everyone who has a UIQ 3 phone... Just do a simple test... Open SE website on ur phone, in the default browser... Then go to press release and then the media section... Download a pic and see how long does it takes...
I did this with my P990 a long time back... And guess what??? I download a 3MB Picture from SE site and it took just 15 seconds... This means that the download speed was almost as fast as 2Mbps, just what I have on my laptop... (If anyone can't calculate just PM me)
But I am very sorry to say the speed during browsing is too slow... I think the reason might be either the phone's processor or it's the browser... But it's not the WiFi that's slow... The WiFi is fast enough and in India we only have 8Mbps as the highest speed at present... So even though I would prefer a wifi b/g than only b, I am satisfied with the speed just not the browsing experience... |

The important difference between b and g is in the way that they work. G will give a better signal and better performance in an enclosed space - its much less susceptible to interference from outside sources and less prone to having problems with the signal being reflected by walls etc.
Symbian seems to have something of a problem with WLan transfer speeds though, there is an interesting article somewhere on the net which details transfer speeds outside of the web browser on a N95. They did not get full speed from the connection, and indeed found some interesting performance drop offs with certain packet sizes.
As to the original poster, I'd ensure I was on latest firmware myself, WLan seems to be somewhat faster on the newest firmware, at least it seems that way for me. |

Here's that paper. (SymSmb development has started to recruit for betatesting for the UIQ version, btw  ).
In any case, it seems (I'm guessing) like there's a theoretical maximum of 5.5Mbps on the p1. And that translates into a throughput of about 2,5Mbps (320kb/s) in absolutely ideal circumstances. But (guessing again) it's likely that bus- speed, error correction and pauses, overhead, memory recovery and so on - and perhaps a weakness in symbian with returning calls, or perhaps an implementation weakness in the way external calls need to be resolved completely before negotiating a transfer again, and things like that - you'll never get all the way to that speed. Or, what you really get is peak speeds on somewhere near the maximum - and then drops for whatever different reason, and averages *wave* somewhere below that.
..some 250Kb/s isn't exactly bad on a mobile, though. Compare with the n95 in the linked test, for example (which tests in ideal conditions).. And, I mean, the n95 has about twice the processor speed, a newer modem, more power drain, as well as a quicker internal bus..
In other words, the only reason to get G- support for a phone would be if your network doesn't support b- standard. And, btw, the only reason a G- network is typically more resilient to noise, is that it pours more signal into it, and generates larger peaks on the signal. And then surviving more interference in practice. There's not really all that much about the g- standard that's inherently better than the b- standard. I mean, there's been other handshake and encryption algorithms introduced together with the g- standard that's very useful, and so on, but other than that.. |

Another thing - about the initial post: 1,5Mbit (megabit per second) is about (1,5*1000)/8 = 188Kb/s (kilobyte per second). And depending on the weather, that's about what you'll get on the p1 as well.
..You know, it wouldn't suprise me if it turned out that all the current mobile phones use the same chips in their modems..

Well, that makes kinda sense - when you think about it. |
