The Wall Street Journal reports on an expected demonstration by Samsung of a 4G network: Many kinds of networks are now labeled 4G (fourth generation), such as Sprint Nextel's planned mobile WiMax network, because 4G originally meant "all Internet protocol." No more of this circuit-switched emulation with proprietary this and that. (There will probably still be proprietary this and that in 4G, of course.)
Samsung will reportedly show a mobile data system that operates at 100 Mbps at speeds up to 60 km per hour (37 miles per hour) as well as a nomadic connection with 1 Gbps performance. The Journal notes that NTT DoCoMo showed 2.5 Gbps at 12.4 mph--in the lab--as part of a previous technology demo.
Service using this definition of 4G isn't expected until 2010.
Update: Coverage from the Korea Times says that "yesterday's" demo--the international dateline plays havoc with us all--showed not just a demonstration of 1 Gbps performance at rest, but Samsung disclosed they had hit 3.5 Gbps at 5 km/h (3 mph) in the lab, thus surpassing NTT DoCoMo's reported top rate.
The demos took place in a bus that showed 32 simultaneous streaming high-definition video streams while video telephony and Internet browsing was also going on.
