9.1.3 Wireless Architecture Facts

There are (a)   types of frequency bands used on wireless routers.

The (a)   GHz range is a longer frequency that can travel through physical barriers like walls and floors.

The (a)   GHz range has a faster transfer rate, allowing it to move data more quickly.

• This allows the data stream to be more unpredictable from outside the network, making it harder to intercept and eavesdrop on.

• Direct sequence spread spectrum

• Orthogonal frequency division multiplexing

• Frequency hopping spread spectrum

it can avoid interference if certain channels are blocked within that frequency.

• Direct sequence spread spectrum

• Frequency hopping spread spectrum

• Orthogonal frequency division multiplexing

Makes the transmitted bandwidth signal wider than the data stream needs.

• Orthogonal frequency division multiplexing

• Direct sequence spread spectrum

• Frequency hopping spread spectrum

• Uses a physical mesh topology with a logical bus topology.
