Ultra-Wideband: New Ultra-Connectivity for the Enterprise?: Page 8 of 9

According to Staccato Communications' Aiello, the main impediment for UWB in the enterprise is concern about security.

"Nothing else holds back the IT manager," he said.

There was a time when IT personnel installed a new network element and then watched for security problems, but today assuring network security comes first. Aiello said what some see as UWB's biggest negative - its short range - actually could help quell security concerns.

For instance, if a network is configured so access is not granted below, say, 54 Mbps, UWB's range then would be limited to the immediate area. This would significantly reduce the possibility of improper use.

Yet not every enterprise necessarily wants to improve its network, especially if it represents change. While Staccato's Aiello said, "combining an 802.11 network with UWB will create the ultimate capacity for the enterprise," to reach this pinnacle, UWB devices must prove they cannot only work together but interoperate with myriad other wireless devices without interference.
