RTS-CTS – Request to Send, Clear to Send
|
o Host Transmits a Request to Send Signal
o Access Point Transmits a Clear to Send Signal Host may transmit Others must wait o RTS/CTS is optional |

802.11 Standards:
|
- 802.11g – most common
- 802.11n – becoming much more common, catching up with 802.11g - LOOK AT POWERPOINT |

MIMO – Multiple Input / Multiple Output
Wireless Mesh Networks No wired LAN Uses multiple access points to forward frames to each other Difficult to design and implement Smart Antennas Can direct signal energy to and from devices Helps to determine the best way to send a signal |
- Uses different antennas (may be internal, you may not see them) to send the data
- Signals arrive at different times based on when sent by each antenna - Allows for higher speeds, can send more information - Longer propagation distances |

Wireless Mesh Networks
|
- No wired LAN
- Uses multiple access points to forward frames to each other - Difficult to design and implement because access points in the middle tend to get overloaded |

|
Smart Antennas
|
- Can direct signal energy to and from devices
- Helps to determine the best way to send a signal - gives stronger signals |
