Posted in Telecoms, 26th March 2008 20:09 GMT
Australian wireless carrier Buzz Broadband has shuttered its WiMAX network, describing the technology as a "disaster" that has "failed miserably".
Speaking at an international WiMAX conference in Bangkok, Garth Freeman, CEO of Buzz, claimed the technology didn't work indoors more than 2Km from the base station and had latency as high as a second. High latency is a problem for many internet applications, including the VoIP service that Buzz promoted to get customers.
The lack of in-building penetration is a result of using high frequencies, which can carry lots of data but have shorter ranges and can't get into buildings, as anyone using a 3G network will testify. There has been a hope, in the industry, that WiMAX would magically solve these problems but radio frequency physics remain problematic."
Det är nu det vi pratat om länge men politikerna vill så gärna tro att det går att helt magiskt klara sej undan billigt - men så blir det mycket dyrare i längden då man snålar på de initiala investeringarna. Som att köpa dyra stövlar som håller i 50 år mot att köpa billigt skräp som måste förnyas varje år och hela tiden läcker ...
Radioteknik ÄR besvärlig och med usla protokoll så fungerar den riktigt dåligt - som WIMAX. Mobiltelefonin har åtminstone tuffa protokoll som hanterar de värsta problemen någorlunda hyfsat. Men deras basstationer är riktigt dyra ...
