Works in the 2.4 GHZ range

802.11A
Speeds up to 54 mbps
It has 23 clean channels (with no overlap)
Works in the 5.9 GHZ range
Cell radius of about 270 feet

1. Determine the number of networks required and convert to Binary
5 in binary is 00000101
So the first three bits of the last Octet is required for the subnet mask
128 + 64 + 32 = 224
The new Network Mask is 255.255.255.224

2. Reserve sub-net bits and determine Network Increment Range
The sub-net bits are the first three bits of the last Octet
A total of 8 subnets are possible here. Although we need only 5
    To calculate the number of subnets, its 2 to the power
    of the number of sub-net bits or 2 to the power of 3.
The Network Increment Range for each of the seven sub-networks is equal
to the smallest subnet bit value. In this case: 32

3. Use Network Increment Range to determine host IP range for each sub-network
Network ranges:
Sub-Network 1 -     192.22.5.0 to 192.21.5.31
Sub-Network 2 -     192.22.5.32 to 192.22.5.63
Sub-Network 3 -     192.22.5.64 to 192.22.5.95
Sub-Network 4 -     192.22.5.96 to 192.22.5.127
Sub-Network 5 -     192.22.5.128 to 192.22.5.159
Sub-Network 6 -     192.22.5.160 to 192.22.5.191
6 - Not required This example
Sub-Network 7 -     192.22.5.192 to 192.22.5.223
7 - Not required This example
Sub-Network 8 -     192.22.5.224 to 192.22.5.255
9 - Not required This example

Each network can support up to 30 devices as
the first and last address of each range are used
for the subnet ID and Broadcast Address.
