Flashcards do conjunto (9)
- 1is High-Rate DSSS (HR-DSSS) operate is the unlicensed 2.4 GHz to 2.4835 GHz ISM band802.11b
- 2operate in the 5 GHz frequency space using an RF technology called Orthogonal Frequency Division Multiplexing (OFDM)802.11a
- 3Used a new technology called Extended Rate Physical (ERP) -ERP-OFDM- but were still meant to transmit in the 2.4 GHz to 2.4835 GHz ISM Frequency band Data rates of 6, 9, 12, 18, 24, 36, 48, and 54 Mbps are possible using this technology802.11g
- 4defines a new operation known as High Throughput (HT) This provides PHY and MAC enhancements to support data rates of up to 600 Mbps an therefore aggregate throughput above 100 Mbps802.11n
- 5amendment defines Very High Throughput (VHT) enhancements 6 GHz. The technology will only be used in the 5 GHz frequency bands where 802.11a/n radios already operate Wider Channels 802.11n introduced the capability of 40 MHz channels, which effectively doubled the data rates 802.11ac brings us the capability of 80 MHz and 160 MHz channels802.11ac
- 6This amendment defined a Robust Security Network (RSN) The intended goal of an RSN was to better hide the data flying through the air while at the same time placing a bigger guard at the front door802.11i
- 7Authentication 802.11i defines two methods of authentication using:IEEE 802.1X authorization framework or
preshared keys (PSKs) - 8a client station is able to establish a QoS stream and set up a security association with a new access point in an efficient manner that allows bypassing 802.1X authentication when roaming to a new access point802.11r-2008
- 9to provide a way of delivering management frames in a secure manner802.11w (robust management frames)
