What is one of the biggest risks facing wireless devices?. Wireless communications were always prone to security issues well before any of the 802.11 standards. So the AT&T Lab members created a report, Labs Technical Report TD-4ZCPZZ, “Using the Fluhrer, Mantin, and Shamir Attack to Break WEP.” This test was successful in breaking WEP encryption. This is because the SSID is part of the process of connecting to a wireless network.

Wireless Networking Security

In the case of a 2 or 5 MHz radio band and transceiver power up to 1 W (as in the case of the current wireless LAN standards) the wireless communications can usually be heard from outside the building where the network is operating. Wireless Networking - SANS ©2001 14. Use encryption in the higher layer protocols. Automated tools are freely available to crack WEP encryption, so it is necessary to implement encryption in the higher layer protocols. Wireless Networking - SANS ©2001 15.

Digital RF Transport

tailieu.vn

In wireless communications, poor dynamic range is most apparent in data communications. Clearly, wide dynamic range is critical as more data services consume the wireless spectrum.. What limits dynamic range in an analog RF transport system? Loss and noise. And RF transport systems generate a variety of noises. Figure 2 compares the impact of loss and noise in analog and digital RF transport systems.. It is loss and noise that make digital and analog RF transport systems so different.

Cisco Unified Communications Unifying Communications Communications Infrastructure

Management can easily align this one unified system to the business core values, while delivering on the com- mitment to provide one system that meets all of the company’s communications needs.. Cisco’s unified communications vision combines individual systems with different communications capabilities into a cohesive, powerful communications ecosystem. The power of the system is not the system itself, but the human capabili- ties that are enabled from the utilization of the system.

E-Band Wireless Technology. The 71-76 and 81-86 GHz bands (widely known as “e-band”) are permitted worldwide for ultra high capacity point-to-point communications. E-band wireless systems offer full-duplex Gigabit Ethernet connectivity at data rates of 1 Gbps and higher in cost effective radio architectures, with carrier class availability at distances of a mile (1.6 km) and beyond.. The significance of the e-band frequencies cannot be overstated.

Throughout its million square-foot campus, Cedars-Sinai relies heavily on fast and reliable communications. Prior to the year 2000, Cedars-Sinai relied on a combination of overhead paging, beepers and two-way radios to connect with its physicians and staff, as was the case with most hospitals at the time. But in its continuing effort to provide the best care, Cedars-Sinai was an early adopter of wireless infrastructure as a means of speeding communications..
