Systems and methods for communication protocols in communication systems are disclosed. In some embodiments, systems and methods for communication protocols in communications systems include implementing efficient techniques for supporting single and multiple protocols. In some embodiments, systems and methods for communication protocols in communications systems include providing a multimode communication device that includes a first network layer configured to route data between nodes on a network according to a first network layer protocol; a first logical link control layer in communication with the first network layer and transmitting data to and from the first network layer and providing data flow control; a second network layer configured to route data between nodes on the network according to a second network layer protocol; a second logical link control layer in communication with the first network layer and transmitting data to and from the first network layer and providing data flow control; a media access control layer providing channel access control and transmitting data to and from the first logical link control layer and the second logical link control layer; a physical layer configured to transform data received from the media access control layer into signals for transmission and transmit the signals, to receive signals from the network, convert the received signals into data and provide the data to the media access control layer.
