Limitations to Line of Sight
Limitations to Speed
Limitations to Bandwidth
Direct Sequence Spread Spectrum
Combines data signals with higher bit rates to transmit over a wider band.
Frequency Hopping Spread Spectrum
Hops from various frequency channels to spread the signal.
Orthogonal Frequency Division Multiplexing (OFDM)
, Has overlapping signals act independently to increase data transmission efficiency.
Multiple Input Multiple Output (MIMO)
Uses multiple antennas to increase channel capacity
Wireless Local Area Network (WLAN)
Manages the use of wireless devices, which have sensors or antennas to connect and
communicate over high frequency radio waves. However, since these signals reduce the need
to depend on wires, it does not mean that cables are omitted.
Local Area Networks
Wireless systems are typically integrated into...
Wireless Router
Performs functions of a router and includes a built-in access point (AP) that connects
wireless-enabled devices to the internet, wired LAN, or WLAN. These are mostly used in
residential and small business where many users can be supported on a single device.
Wireless Access Point (WAP)
Small base station devices with a built-in network adaptor, antenna, and radio transceiver.
Wireless Access Point (WAP)
Organize the communication of all wireless devices connected in a wired LAN.
Wireless Access Point (WAP)
Mostly used in large businesses and venues to provide wireless services.
Wireless Network Interface Card (WNIC)
A radio transceiver that enables wireless connectivity to a WLAN. These are typically connected
to a computer's motherboard or USB port.
network topology
refers to the location of devices so they can communicate and provide optimal coverage and
capacity.
