In relation to the 802.11 series of standards, which of the following best describes Direct Sequence Spread Spectrum (DSSS)? Select two.
- DSSS is more sensitive to fixed-frequency RF noise in the 2.4GHz ISM band than FHSS.
- DSSS is more significantly affected by multipath from narrowband sources than FHSS.
- A DSSS access point can handle a larger number of simultaneous connections than a FHSS access point.
- DSSS has higher throughput in Point-to-Point links than FHSS.
Answer(s): A,B
Explanation:
service set identifier (SSID) is a unique, case sensitive, alphanumeric value from 2-
32 characters long used by wireless LANs as a network name. This naming handle is used for segmenting networks, as a rudimentary security measure, and in the process of joining a network. The SSID value is sent in beacons, probe requests, probe responses, and other types of frames. A client station must be configured for the correct SSID in order to join a network. The administrator configures the SSID (sometimes called the ESSID) in each access point.Some stations have the ability to use any SSID value instead of only one manually specified by the administrator. If clients are to roam seamlessly among a group of access points, the clients and all access points must be configured with matching SSIDs. The most important point about an SSID is that it must match EXACTLY between access points and clients.
There are two kinds of scanning: passive scanning and active scanning. In finding an access point, client stations follow a trail of breadcrumbs left by the access point. These breadcrumbs are called service set identifiers (SSID) and beacons. These tools serve as a means for a client station to find any and all access points.
