no but id love to know more about the company.......24Mb wireless....for residential...thats amazing.....how much?
I don't know, where you saw 24 mbit/s.
There's a 2 mbit (24:1 contention) and 3 mbit (16:1 contention) packages.
Now, these are fairly straight forward FWA packages and most FWA ISPs can deliver these.
WiMAX is more expensive to rollout at the moment and still has child sicknesses. I know of issues with one of the manufacturers for FWA equipment, where their WiMAX not is up to par yet, so most providers move straight back to the older products, once they tried it. Too many quality issues yet to sort out. Other WiMAX products seem to work well. Essentially Fixed WiMAX is just the next generation of FWA non-Wimax products and will slowly replace the older solutions over the next years, increasing bandwidth a tad for the users and improving latency, but it is NOT revolutionary !!!
Providers specificly advertising for it are just taken advantage of the hype around it, that's all

Roaming to different countries presumes same band or a multiband modem. That's hardly possible with Mobile WiMax as in many countries any allocation is either too small or too high a frequency or non-existent.
Same argument used for GSM. You have multi-band GSM devices out there now don't you?
In most countries 3.5GHz/3.6GHz is used for Fixed Wireless. Pretty useless band for mobile use.
Actually no, higher frequencies allow for better mobile handover and give higher throughput rates dependent upon QAM level obviously.
700MHz is only available in the USA at present and they have decided of 3G/LTE route for that band.
Not true. Look at Asia, Pacific, Australia, even Ireland...
2.1GHz is 3G in Europe.
2.3GHz is in use already, though Comreg has allowed a test
2.6GHz is about the only Europe Mobile WiMax band and not available yet in many countries. Not available in Ireland due to MMDS.
The 'two bands' actually **** up WiMAX IMHO - although they allow for a greater distribution of cells and thus reduce overall network cost (approx. by a factor of 2 to 'three band').
Due to lack of infrasturcture EDGE/3G for Data is about 80% ++ used for Fixed Internet access in Ireland. In other countries EDGE/3G/HSDPA is mostly used for Mobile/Ronaming use.
No idea where you get the idea that EGDE/3G has 80% fixed usage in IE - but there ye go.
There is ONE Mobile WiMax handset, a few PC Modems and one dual 3G/WiMax mobile. Virtually all are Operator/Country specific.
Similar argument to GSM initially. At the start travellers had multiple handsets for different markets. I had three for travelling.
As well as USB, PCMCIA, ExpressCard, MiniPCI, and other laptop/PC formats there are pocket WiFi/Ethernet routers and DATA GADGETS with EDGE/3G/HSDPA.
I'd have beleived you two years ago re WiMax built into laptops & Gadgets (apart from phones), but mostly it isn't happening and looks less likely. You'll get WiFi/BT/EDGE/3G/HSDPA built in on many netbooks/laptops. Mobile WiMax is likely now to be only niche product for two operators Sprint/Clear in USA and the Summa Telecom in Moscow.
Don't agree. Intel will push WiMAX enabled chipsets with their mobile chipset package.
Many EDGE/3G/HSDPA modems support 5 bands. As do many smart phones, allowing almost worldwide use. I'd have believed it was coming 4 years ago, but even the largest network (Sprint/Clear) is depending on the Intel/Motorola/Google money. They'll reband to another band unless you sign up for about 1M modems.
If you read into any of the WiMAX operators and vendors, you will see that they have planned their business around producing full coverage and market penetration by around 2012. They're just building their networks now. As Three did over the first few year before 'real' launch.
A few years ago for Data the competition was IPW (taken over by Nextwave for TDTV), Kyocera iBurst, Flarion Flash-OFDM (taken over by Qualcomm) and Mobile WiMax.
IPW vs WiMAX was Beta vs VHS - WiMAX won.
GSM has progressed from GPRS to EDGE and EDGE2, 3G to HSDPA, HSUPA and HSPA+, CDMA-1 has stalled on EVDOrevA, Rev b is dead due to LTE.
The problem that all of these have had in the past is overselling, quoting the peak sector speed as if this is a user speed and neglecting to mention that speed is as little as 1/20th on some at cell edge and that for real broadband speeds and user loads you need 20MHz+ rather than the 1.25MHz, 4MHz or 5MHz that operators really have.
Fundamental misunderstanding of the capabilities of the technologies here. They do what they're designed to do. Technically, they're 'broadband' (hate using the term) - practically they do not deliver what the press, media, marketing, etc... present as 'broadband'.
Then for a dense urban network you need x3 or x 6 the spectrum to avoid interference. Mobile WiMax only solves Multipath. It doesn't solve issues of Spectrum/ power/speed/capacity/range magically. Some things it doesn't even do as well as EDGE or HSDPA, and certainly worse in all cases than Flash-OFDM. LTE on the downlink is also OFDM.
Spectrum efficiencies and channel planning are fundamentally RF problems. The issue to date is that very few RF people can make the logical leap to RF for data and design to their training - i.e. GSM. Ne'er the twain shall meet...
Mobile Wimax is never going to deliver Broadband.
Mobile anything is never going to deliver 'broadband' as 'broadband' is 'presented'. It will deliver mobile data at an approrpiate throughput to the technology used.The CPE (user Modem) hasn't enough power and the allocations don't have enough spectrum.
Not true. Power is defined by the regulator. Spectrum is always a factor for any mobile technology. The spectrum allocated in 3.5 and 3.7 in Ireland does the job.
Real broadband needs copper, coax, fibre or controlled contention FIXED wireless. At a pinch a Nomadic Wireless system with much higher power than MobileWimax/EDGE/HSDPA and option for a fixed aerial can do Broadband.
Agreed.
However, WiMAX isn't what people think of as broadband. Similarly, other mobile data technologies.
My forecast for 2009 /2010 is that Mobile WiMax will be a "ghetto" system run by Niche operators that can't get GSM/EDGE/3G/HSDPA or LTE licences and used only by those that can't get real broadband and not too worried about a real mobile/roaming system for all cities and most countries.
My forecast is that over the coming four years WiMAX may merge with LTE - both taking the other's good 'bits' and dropping the bad 'bits'. Also, that VoIP will become more prevalent and handsets will become data devices with voice rather than voice devices with data.
WiMAX may win out, however, as the backoffice and CSN is less complicated and more flexible. Handover remains an issue - however, a vendor rather than a standards based issue...
It's been over hyped. Big time.
It's been misunderstood and misrepresented. Big time.
Telco is scared of WiMAX as they are too heavily invested in the progression of GPRS/EDGE/3G/HSDPA/CAMEL/LTE/yadda yadda yadda. WiMAX is a lower cost implementation. Also, the need for top heavy organisations with massive transmission, RF, OAM, departments overpaying under qualified jumped up pencil jockies who call themselves Engineers who can't Engineer their way out of a paper bag without raising a trouble ticket to the vendor.
"Where's my support on that?" - Dear Lord!
Now, don't get me wrong - I'm not all gun-ho WiMAX FOR EVAH. It's just misunderstood and misrepresented. Someone needs to set things straight.0
probably not then...
