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

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.

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

Towards WiMax
--- 8< --- snip --- 8< ---
Till these days, hype on WiMax is never ending. I still see media reports promising 50 Mbps bandwidth for up to 70 km radius of coverage. Such performance may be possible only if there is only one user using a WiMax base station which is going to be a very expensive proposition! WiMax cannot solve all broadband problems. There are limits of what it can do. If we can get to share 20 Mbps within up to two km radius, we should be ecstatic. With such performance, to provide 20% of coverage for the whole of Malaysia (with a total land area of 330,000 sq km) it would require at least 5,000 base transmission stations (BTS). If a BTS only manages to provide good coverage within one km radius, the figure would increase to a staggering 20,000 BTS. Assuming 10,000 BTS are required and each one would cost RM 250,000, the total investment would be RM 2.5 bil (excluding the end-user devices and civil works)! With a possibility of 2 mil subscribers, the cost per subscriber would be RM 1,250. But the margin of error in the number of BTS could be as high as 100%. [Note: The above figures are for illustration only.]. Does this make sense? I leave it to the readers to ponder.

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

err...i think he means to make we ponder how much to make the subscription cost and when ROI can be achieved based on that monthly subs fee..if RM50/month...ROI would be 25 months...would any company wanna sustain that long?

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.

yup, I know that he wants us to ponder (I did quote his particular line with bold letterings)... but to even suggest or implying subscription rates be in the vicinity of that RM1250, to me, is simply ridiculous. biggrin.gif

However I do respect his other views. smile.gif

true la banzai...i realize that his calculation doesnt seems realistic if v to pay rm1250 monthly...the jus say suggestion but stil he's abit OVER bout it..
he stil has the wireless broadband rite..so dun la intimidate ppl bout the high cost of wimax rite?
my2 cents but he is funnyly weird showing abit of sore loser face..kaka
no offence

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

2.3 ghz band because it is the most popular. the fact is that there are many spectrun reserved for wimax, the one awarded to these smaller companies is the 2.3 ghz spectrum. most telcos in malaysia have spectrum in the range of 2.5, 3.5, 5.x and 10.x already assigned to them all the way back to circa 2000/01 that can be used for wimax so they don't really need the 2.3 ghz.

why they participated in the tender i don't know. a political stunt perhaps? the telcos are already testing wimax in certain areas using equipment designed for 2.5 and 3.5 ghz spectrums so no biggie to them.

good for their share price only.

Wimax a long long way to go.

Interesting, to get the 4 Wimax 2.3Ghz licensee to build a single network. A recepi for non starter.

Then why bother issuing 4 spectrum block then?

I guess CMC haven't thought thing through b4 carrying them out. rclxub.gif

KTAK inc probably rollout wimax and then lease the network to the 4 licensee.

At least thing would happen

Remember the recent announcement that WiMax services will be available in Msia b4 the end of the year?

Has anyone heard when the service will be launched in Sarawak? Or anywhere else for that matter. So far it seems so silent.

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