Which of the following is true of a 2.4 GHz RF link at a distance of 5 miles (8 kilometers).(Choose all that apply)
Answer(s): A,D
From the study guide, Visual LOS is not required for a successful point-to-point connection. However RF LOS is required. Additionally, the Fresnel zone must be at least 60% clear of obstructions. Earth bulge is only factored in for greater then 7 mile links.
Which two RF spread spectrum technologies does IEEE specify in the 802.11 standard? (Choose two)
Answer(s): B,C
REF FOR B: a typical 802.11 frequency hopping WLAN might be implemented as an enterprise wireless networking solution while HomeRF is only implemented in home environments due to lower output power restrictions by the FCC ORFrequency agility refers to the radio'sability to change transmission frequency abruptly within the usable RF frequency band. In the case of frequency hopping wireless LANs, the usable portion of the 2.4 GHz ISM band is 83.5 MHz, per FCC regulation and the IEEE 802.11 standard.REF FOR C//In the 2.4 GHz ISM band, the IEEE specifies the use of DSSS at a data rate of 1 or 2 Mbps under the 802.11 standard.Under the 802.11b standard-sometimes called highrate wireless-data rates of 5.5 and 11 Mbps are specified.
What are the two types of scanning used with wireless LANs? (Choose all that apply)
When you install, configure, and finally start up a wireless LAN client device such as a USB client or PCMCIA card, the client will automatically "listen" to see if there is a wireless LAN within range. The client is also discovering if it can associate with that wireless LAN. This process of listening is called scanning. Scanning occurs before any other process, since scanning is how the client finds the network. 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.
A wireless portal interconnects LANs conforming to what IEEE standards? (Choose two)
Answer(s): A,C
An access point is considered a portal because it allows client connectivity from an 802.11 network to 802.3 or 802.5 networks. Access points are available with many different hardware and software options. The most common of these options are:? Fixed or Detachable Antennas? Advanced Filtering Capabilities? Removable (Modular) Radio Cards? Variable Output Power? Varied Types of Wired Connectivity
