this not true wimax, my company use it... airzed using antenna and install into your premis... their transmitter at menara meraih ss19 pj..... true wimax using wifi card a/b/g....looooo...!

p/s: airzed control bandwith using packeteer packetshaper.....p2p very damme slow...!  vmad.gif

True wimax is not compatible with WiFi, dont give out wrong msg

WiMAX wont solve all issues, at best, the ping will be around 200ms. You won't want to play games with that kind of ping.

where is ur source to gv that comment? u built wimax izit? u so sure would be like tat?
damn la...pesimistic...i didnt say its bad...im saying u are full of shit or wat but hope u show abit prove b4 gv some weird claims la....no offence alrite?

i knw for the fact is wimax can bring tmnut to their knees to offer better service n cheaper price.ok..lets hope on ppl!!! icon_rolleyes.gif

Guess what, you are partly correct smile.gif

Well, bysquashy isn't talking crap. Any wireless tech. will always have poorer network latency than copper wire. You can't defy the law of physics. Look at it this way: air < copper < fiber optic

~200ms is, IMO, the average latency for OFDM (i.e. WiMAX) to the next hop (i.e., base station), after considering user traffic and NLOS-ness (Non Line-of-Sight). It can be better than 200ms, but you'd have to be one of the handful number of users camping on the WiMAX base station AND be in LOS to it. Best case scenario should be about 50-100ms. BTW, network latency to the Internet is subject to the number of hops taken to its destination, so that may very well exceed 200ms on average.

(prior to the WiMAX tender, I don't think anyone has ever heard of MIB Comm... ;P)

We tested with the current equipment, 1 AP to 1 CPE indoors, the latency is ~250ms. I'm not saying that technology won't improve, but this is my 1st hand exp.

but im stil in the blur state...this wimax run in 2.3ghz spectrum with 802.1a/b/g rite? so our normal laptop wit wifi capability could jus detect it n connect la...if i wan to get those extra usb extension antenna thinggy...need to buy la?
since u r wimax technical ppl....

Yeap, you'll need a new CPE. Intel will embed WiMAX in their new system, just like Centrino for WiFi, so we'll just need to wait a bit more. IIRC, WiMAX can run on 2.3Ghz-3.5Ghz, 2.3Ghz is the spectrum offered in Malaysia. Jaring plans to use thier 2.5Ghz spectrum to operate WiMAX. Most spectrum offered in other parts of the world is 2.5GHz.

got to improve the backbone first laa. of course the backbone are TM.

True.

QUOTE(husagi @ Mar 25 2007, 02:04 AM)
WiMAX is not WIFI (IEEE802.11a/b/g)
WIFI is not WIMAX

For both standards to be inter-operable, you'll need dual-band access device. If you want dual-band devices, you wait la. I think the cows will come home first. biggrin.gif

Once you have dual-band devices, then you can think about making your own home-made dual antenna systems. smile.gif

Wah....... that would be redundant biggrin.gif

so bysquashy, if interband connectivity is possible....then my place i put up tment n make it wifi, i could jus access my own broadband at home thru this wimax network izit?

wah then the hopping will me so much greater..like 300-400ms la....ok ok
another question, the CPE u talking bout is the usb thing izit? here can buy ah? u can gv recommend? i saw it on the net but i dunno what izit called...i tot there was 1 which could excess even 3g network n wimax....u got any idea?

I dont get the bolded part.
I think you got something wrong, for WiMAX its like GSM, you don't own the BTSs, you only own the handphone. So in wimax's case, you'll only need to have a CPE or wimax capable laptop. For WiFi, you need AP and the wifi card.

The CPE that we tested is PCMCIA for lappys, its spec can support up til 10Mbps. WiMAX technology is still at a infancy age. As we are talking, the RnD is still solving many issues and trying to live up to its name.

I'm assuming you are asking when will it be ready for the market? I would say sometime around Q4 2007 or Q1 2008

RM1250 ???

Im pondering...

10,000 BTS
cost RM 250,000 per station
Total investment = 10,000 x rm250,000
= RM2,500,000,000 (ie RM 2.5bil)

Total possible subscriber = 2,000,000 (ie 2 mil)

Cost per subscriber = RM2.5 bil / 2 mil
= RM1250/-

I would say the above is FLAWED CALCULATION as it ASSUME ONE TIME SUBSCRIPTION PAYMENT. But subscribers pay every month.

And according to the "flawed" calculation, if the total investment can be paid back in one month period... ITS A DAMN GOOD BUSINESS as the service providers receive RM2.5 billion monthly (excluding other costs)...  whistling.gif

RM250K for a base station would be naive, there are a lot more cost into it. Such as upgrading the current backbone, integrating with it, etc etc


Added on March 28, 2007, 10:20 amI have an interesting news to share

QUOTE
Fitch: WiMAX will be 'moderately disruptive' for telecoms mart
Source ~ Business Times
News is updated by Corporate Resource Library

Mac 26,    FITCH Ratings last week said the emergence of WiMAX services in Malaysia would be "moderately disruptive" for the telecommunications market over the longer term.Malaysia recently awarded the much sought after WiMAX spectrum to four small bidders, sidelining bids from three large telcos, namely Telekom Malaysia ™, Maxis Communications and DiGi.

Fitch said while Maxis should remain relatively unaffected there would be implications for TM's fixed broadband operations as well as for DiGi's longer term competitive position in mobile communication.The four successful applicants were Bizsurf (M) Sdn Bhd, MIB Comm Sdn Bhd, Asiaspace Dotcom Sdn Bhd and Redtone CNX Broadband Sdn Bhd, with the first three each awarded 30MHz in the 2.3GHz band for provision of services in Peninsular Malaysia, while Redtone was allocated 25MHz in the same band for Sabah and Sarawak.

The licence allocations are tied to stringent rollout requirements, which call for a service provision of at least 1Mbps and 40 per cent population coverage by 2009, at an estimated capital expenditure of about RM300 million for each operator over the next three years.Fitch said although WiMAX, the trade name for a group of wireless standards that encompasses both fixed-wireless and portable/mobile deployments, is still largely an unproven technology, it could prove moderately disruptive to telecom markets over the longer term.

"By eliminating the need for copper or fibre last-mile installation, WiMAX offers a lower-cost replacement option for traditional broadband solutions such as digital subscriber lines (DSL) and cables."Additionally, the mobile version of WiMAX is expected to support voice and data access at high vehicular speeds," said Priya Gupta, director, corporates.

Impleamentation of WiMAX will be a bit hard due to technical difficulties because I think its only Malaysia using the 2.3Ghz band.

I know there is one operator providing Pre-WiMAX even before the license spectrum is tendered.

May be it will be something like Maxis's wireless broadband modem.
