Wireless Broadband Router

bits in the chip are damaged during transmission, statistical techniques embedded in the radio can recover the original data without the need for retransmission. To an unintended receiver, DSSS appears as low power wideband noise and is rejected (ignored) by most narrowband receivers.

Question Would the information be intercepted while transmitting on air?

Answer WLAN features two-fold protection in security. On the hardware side, as with Direct Sequence Spread Spectrum technology, it has the inherent security feature of scrambling. On the software side, WLAN offers the encryption function (WEP) to enhance security and access control.

Question What is WEP?

Answer WEP is Wired Equivalent Privacy, a data privacy mechanism based on a 64-bit or 128-bit shared key algorithm, as described in the IEEE 802.11 standard.

Question What is WPA?

Answer Attempting IEEE802.11i standard, Wi-Fi Alliance has chosen from preliminary version a group of specifications called WPA (Wi-Fi Protected Access).

Specifications of WPA are:

•TKIP Integration (Temporal Key Integrity Protocol) to allow key change dinamically and integrity control of packets.

•Advanced mechanism to manage authentication and access control to network services in centralized mode (802.11x through EAP, TLS use is necessary)

•Authentication key is different to key used for encryption

This protocol is more strong that WEP encryption.

Question What is WPA2?

Answer Recently approved by Wi-Fi Alliance, the new standard WPA2 is an evolution of WPA (Wi-Fi Protected Access), supported by almost compatible IEEE802.11g clients.

WPA standard, required to repair WEP weakness, has only a
