With the advent of multi-processing and multi-core systems, parallels in multiplexing radio-frequency (RF) transmission by Multiple-Input-Multiple-Output (MIMO) is advantageous. Convergence architecture for Beyond-Fourth-Generation (B4G) communications is considered utilizing open standards,MIMO and P2P topology. The system is observed as a software host-media-processing (HMP) appliance aggregated with modularized interfacing for distributed network communications. Experiments conducted on the modular interfacing components demonstrate active and passive wireless link properties of 802.11 b, g and n under LOS, NLOS, VLOS scenarios as compared to Ethernet. Codec's used in the system (G711a, G711u, G723.1, G726-32, and G729a) for communication are tested under QoS bandwidth starvation for behavior of bi-directional throughput within the networked system. UDP protocol saturation tests on IPv6 and IPv4 are conducted. The model of the appliance is proposed for voice, data, and video communications anytime, anywhere.
