NS3 Wifi Projects

Benefits of NS3 WIFI Projects:

• It offers extended access, cost reduction and mobility create opportunities for new applications as well as the possibility of creative new solutions for legacy applications
• Cost reduction.
• Extended access.
• It’s an Ethernet placement.
• Gives flexibility.

Characteristics of WIFI:

• Signal strength and range.
• Speed needs.
• Operating frequency.
• Channels .
• Data rate throughputs.
