To
Yockers about SymSMB 2.00 Wi-Fi speed (^^^ above post).
First of all, let me answer your question. The bottleneck is phone.
Sure, its not unusual for software developers to blame the hardware, right?
So, before making our conclusions we have spend quite some time and efforts.
Was designed and written the special software for various tests.
Tested different phones and different routers and so on.
On another hand the same tests was used to find our if
our own protocol implementations in SymSMB 2.00 are in fact
clear and efficient. ... Yes, they are clear and efficient.
In result you could have a look at article below.
I wasn't able to find on Internet any similar publication, so if someone could send me
some links with similar information, I would really appreciate that. Finally, here is that article:
Wi-Fi. Finding speed... (Wi-Fi speed analysis of some Nokia smartphones)
It is quite big and illustrated publication, if someone feels that it is too big,
then here is some conclusions based on that article, but before that,
in order to save some words, please have a look at one picture from that article.
And below are some conclusions that are based on that publication.
1) Its not worth it to expect in the real life that phone with 802.11b or 802.11g
somehow mentioned in specification, will produce the similar speed that these protocols shows
on another devices that got bigger physical size, more electrical power and bigger antennas,
such as computers, routers and so on.
To put it simple, there are a lot of parameters under 802.11g description
and speed is just a one from them. And that 802.11g 54Mbps as well
as 802.11b 11Mbps are just the "theoretical maximum limits". Many people knows about that,
but not everybody.
2) The maximum real life speed of Nokia's E and N series S60 3rd edition Wi-Fi phones
is not higher then the maximum theoretical speed limit for 802.11b protocol.
3) Factual speed shown by Nokia 802.11b,g phones in ideal conditions is ~ 450 K/s.
4) In the real life it is reasonable to expect on Nokia S60 3rd Ed phones the Wi-Fi the speed around 350 K/s.
But all those are still words from developer, right?
I can offer the another approach as well.
Do you want to bet? Find for me the Wi-Fi application for series 60 3rd edition phone
that will demonstrate in similar condition the faster Wi-Fi speed then SymSMB 2.00
and I will give you a free copy of SymSMB 2.00. If you have paid already, then you will get money back.
Is it fair?
Frankly, i think that in order to be more realistic that should be modified like this:
"Find for me S60 3rd edition Wi-Fi application with
80% of speed of SymSMB v.2.00
and I will give you free SymSMB 2.00 copy."
Now its up to you to pick the more fair offer.
I don't know how you made that 80 Mb copy for 12 min, was it the Server case, or the Client case?
Was it from phone to computer or vise versa?
Still, as from my experience with SymSMB 2.00 your number are rather low then it should be.
Well, You've just made me to make one more speed test. Again.
Conditions:
Phone: N91
Computer: Windows XP, other tasks are also running on computer, during the test average CPU load is 15% and Max never exceeded 50%
Router: Linksys WRT54G with Wireless Network Mode set as Mixed (b and g) and Security mode set to Disabled, MAC filtering is on.
File set: 13 mp3 files with total size
100 Mb (105,267,908 bytes)
Distance between the phone and router: 1 meter.
Server case scenario - copy processes are initiated and performed on computer using Windows Explorer.
from computer to phone E:\ drive:
5 min 03 sec.
from phone E:\ drive to computer:
5 min 55 sec.
Client case scenario - copy processes are initiated and performed on phone using SymSMB 2.00 browser.
from computer to phone E:\ drive:
9 min 55 sec
from phone E:\ drive to computer:
7 min 24 sec
As you can see in my situation all test results are significantly better comparing to yours 84 Mb for 12 min.
There are 3 times advantage in best case and 1.5 advantage in worst case.
I guess that your data are for Client case scenario, otherwise it is significantly lower then it should be.
Again, many things depends on many other factors, how busy is your router, distance between
router and phone, do you have on router Wireless security Enabled or not and so on.
I would recommend do not set Wireless security to Enabled and use MAC filter limitation on router instead.
Make 4 tests like mines before and after and see the results, in some cases Wireless Security can
significantly lower your Wi-Fi speed.
Phone firmware upgrade and the router firmware upgrade are not bad options to have a look too.
If you would like to investigate your situation with the speed any farther
please feel free to contact us at support(AT)telexy(DOT)com or on

P.S.
The Wi-Fi speed on Nokia mobile phones was discussed some time ago
