From the assumption that bacteria nanonetworks are achieving actions of communication through electric potentials and fields, in this paper those processes of (Nitrogen and sugar) phosphotransferase systems (PTS) that would led to bacteria communications, are modeled by classical electrodynamics. Under we propose that bacteria communications are using the free ions of Potassium to exert electric fields to others bacteria to accomplish a determined task such as chemotaxis. Thus the concentration of Potassium ions are the cause to define nanonetworks previous to achieve tasks to improve the wellness of a bacteria population. How these species behave are of importance to prepare and anticipate well-design strategies inside of the territory of the Internet of Bio-Nano Things (IoBNT).
