Cisco is predicting that the advent of 4G services will lead to an explosion of new video applications that will transform telecom service providers into what the company is dubbing “experience providers.”
Suraj Shetty, the vice president of marketing for the Cisco Worldwide Service Provider Marketing, said during an interview this week that companies’ investments [...]
Cisco this week extended its Unified Computing System data center convergence platform with rack mountable servers, saying the new form factor represents an “entry level” into UCS and more choice for customers.

Cisco introduced the CRS-1 (Carrier Routing System) on May 25, 2004, as its first multichassis core router platform.

Bluetooth last week stopped being chained to the low-power, low-throughput radio that has been both its strength and its weakness. New code lets Bluetooth applications now run over 802.11g wireless connections in the 2.4GHz, with a throughput jump to 20M to 24Mbps, from 1M to 3Mbps.
We talked to one of the key creators of [...]
