Congestion occurs when machines send too many packets to a network too quickly from the transport layer. . Performance will become degraded as packets are dropped and lost.. 1 Network Architecture Introductory material This module uses the example from the previous module to review important networking concepts: protocol architecture, protocol layers, encapsulation, demultiplexing Dynamic Wireless Communication between Peer-to-Peer UAVs Simon Khan AFRL Information Directorate Integrity  Service  Excellence Objectives Today’s collection of Tactical .. Wireless is Global. The standard radio frequencies run in the range of 3Hz to 300 GHz. There is other frequencies used for example the 222 MHz through 225 MHz is for amateur radio. If your interested in what frequencies your country is using for what? Take a look at the frequencies.
