NTT DOCOMO will begin verifying its new Long Term Evolution network’s performance in the Tokyo area, prior to the full-scale launch of the fourth-generation network in December 2010.
The aim is to verify the LTE network system for speed, latency, stability of inter-cell handover and other conditions required for commercial operation.
DOCOMO expects to confirm 5 MHz-bandwidth throughput of 37.5 Mbps on downlinks and 12.5 Mbps on uplinks, and later 10 MHz-bandwidth throughput for maximum 75 Mbps on the downlinks and 25 Mbps on uplinks. .

The recent announcement by privately held TelX of its TelX Ethernet Exchange signals the growing trend towards carrier ethernet services for enterprise connectivity and mobile backhaul, says Nemertes Research.
The TelX Ethernet Exchange, offered in partnership with Neutral Tandem, creates a 21-location network of Ethernet exchanges across the United States, similar to the Equinix Ethernet Exchange or CENX.
Exchanges offer enterprises and mobile service providers the ability to extend end-to-end class of service and management services across multiple carriers.
Enterprise interest in carrier Ethernet is skyrocketing, with 73 percent of organizations saying they use at least some carrier Ethernet today, and 91 percent projecting use by the end of 2010.

LTE is the Network of the Future; HSPA+ is the Bridge

LTE is the Network of the Future; HSPA+ is the Bridge
Operators can still rely on their HSPA (high speed packet access) and HSPA+ networks to satisfy customers’ bandwidth needs even as Long Term Evolution gets rolled out globally, said Ronny Haraldsvik, SpiderCloud VP, at a Communicasia panel (Accedian is at the show).
The device ecosystem has to ramp up even after spectrum has been awarded and the networks are built, he said. Furthermore, LTE coverage will only be available in pockets, with operators unlikely to offer nationwide coverage all at once.
Ovum analyst Nathan Burley concurs. “We have to remember that coverage won’t be everywhere from day one,” he said.
Voice support is another issue that complicates matters, as LTE originally was designed as a  high-speed, high-bandwidth data enabler, not a voice network. Burley said voice will still contribute 47 percent of operator revenues into 2015.
That isn’t to suggest anybody thinks LTE is anything but the future. And there is simply some point where it will make sense to switch, said Dirk Wolter, Alcatel-Lucent CTO North and Southeast Asia.
While some observers had deemed LTE and WiMax as competing technologies, most now believe WiMax operators will eventually migrate to an LTE platform to stay commercially viable.
