The downside of using RTS/CTS is that for each data packet you trans-
mit, you must transmit and receive another packet, which will affect 
throughput.
Packet Encapsulation (Encapsulation Menu)
The Encap option and the related encapsulation table commands of 
ShowAdd and Remove are of concern only when both of the following 
conditions exist:
n You are assembling a wireless LAN that incorporates non-Aironet 
equipment.
n The non-Aironet equipment uses a proprietary method of packet 
encapsulation that is different from the method used by Aironet.
If your wireless LAN consists only of Aironet components, use the 
default Encap value of 802.1H and disregard the information in follow-
ing discussion “Packet Encapsulation in Mixed Networks.”
Packet Encapsulation in Mixed Networks
Aironet LAN software allows you to assemble a wireless infrastructure 
using components from different suppliers. When combining equipment 
from different sources into a wireless LAN, you might need to accom-
modate different methods of packet addressing and conversion. The 
complete subject of packet addressing is beyond the scope of this man-
ual, and our purpose here is to provide only basic guidelines and consid-
erations.
To combine a mix of equipment from alternate suppliers into a wireless 
LAN, you need to know the packet encapsulation methods used by the 
different suppliers. If you determine that your infrastructure will be 
mixing packet encapsulation methods, you will first need to determine
