i just got my izzi last night.
outdoor ~ 30-50% signal
indoor ~ 0-50% signal
not good at all
antenal doesn't help also
my area is ss24
anybody know where is the near transmission tower?
dont even want to hare my dl ul speed ...lousy
any tips to increase the signal?

ya i know, but they claim their transmission tower can cover 13km and SS23 is not too far away from ss24 which ss23 (~1KM) is their cover area

ss23 is in their coverage

Added on September 6, 2007, 1:07 pmi'm looking into diy my own cantenna/antenna
to boost up the signal
anybody heard of this?

doing that
wait and see, cos i need internet but not streamyx.

i thought iburst is operating in 1790mhz - 1795mhz range?
is the antenna working with this range?
-----
9 . At what frequency is iZZi in Malaysia operating?
Answer : iZZi in Malaysia operates at 1790Mhz to 1795Mhz band with a 5Mhz bandwidth.

some good news for me as when i point my antenna to different direction i managed to get 200-450kb/s (with 100% signal)
will post up my speed test soon.
i'm going to diy a cantenna soon but hard to find the raw meterial like N connector, good antenna cable & pig-tail
anybody know where to get this items?

this is my best reading & i'm not within izzi cover area

ss24 pj

what to do

anybody know where are their base station?

pls add in here

this is my result after install the homebrew antenna.
Signal improve alot constant 95%-100%
but the dl & up suck big time

I just re-format my pc and the connection seem to be better running @ 300-400kbps and my area is out of izzi coverage and currently using my own home brew antenna.

c the green lights?! it wasn't there before i use my antenna.

signal constantly at 90%-100% but i still happy with the speed, which previously i only get 10-30% signal and 30-70kbps

hi caprina,

will get back to u on this, let me re arrange the step to build the antenna first ok.

cool just dl 400++mb file within 1-2 hrs not using bt

previously i'm using xp sp2 but reformat it to xp sp1, speed improve alot, my MTU set at 1500 but will try 1400 tonight to see the difference.
going to build another antenna soon to see if double antenna is better then one, currently max dl is 80kB/s wan to improve it to 100kB/s or more.

Higher System Spectral Efficiency


In summary, all of the above technical characteristics in a typical iBurst system deployment scenario in a 5MHz spectrum, can be put together to explain how efficient use of frequency is achieved by iBurst system. The maximum data rate per user becomes 1,061 kbps for downlink and 346 kbps for uplink there by resulting in the total throughput per BS of 32.361Mbps as illustrated below.

Max cell Throughput (downlink) 1,061kbps x 21 + 707kbps x 3 = 24,402kbps
Max cell Throughput (uplink) 346kbps x 21 + 231kbps x 3 = 7,959kbps
Max cell Throughput (total) 24,402kbps +7,959kbps =32,361kbps

Since the spectrum (frequency bandwidth) is 5 MHz in typical deployments, theoretical iBurst system's spectral efficiency of total throughput per Base station becomes 32.361kbps/5MHz =6.47bps/sec/Cell

pick up fr http://global.kyocera.com/prdct/telecom/of...icalsystem.html

max per station is 24mbps, how can it support 500 ppl unless it reduce the quality right?

above calculation is based on per based station... i think

i saw the base station in damansara area
look like this one http://global.kyocera.com/prdct/telecom/of...images/f_le.jpg

i listed it in
http://www.wikimapia.org/#lat=3.133199&lon...=18&l=0&m=a&v=2
go add in more
but i dont think they (izzi) will like it

tmn mayang or tmn mayang jaya?
me in tmn megah next to mayang jaya
signal very poor 30% out site

but currently using my own antenna signal went up to 100%

this is my antenna

this is just a prototype, going to enhance to by building another parabolic type. the rec'ver point (N connector) is not perfect so going to correct it in my next project, but in the mean time it's fully functionable and signal is constantly 80-98% during connection even when it's rainning.

not pringles
cos pringles diameter & lenght is not the right type
it's more for 2.4Ghz not 1.79Ghz

izzi down!!!
