An exciter system (1, 2) able to communicate information between an exciter unit (10) and one or more remote units (12) or between multiple exciter units (10). The exciter units (10) may include wireless type exciter devices, such as optimum exciters (14), or they may include wired equivalent type exciter devices, such as direct connect exciters (16). The exciter devices (14, 16) inject or extract RF currents (24) in the metallic framework (22) of a vehicle. The remote units (12) couple electromagnetic fields (26) with the metallic framework (22) of the vehicle. The information is exchanged with the exciter devices (14, 16) by communications equipment (20) that modulates or demodulates the RF currents (24) and/or electromagnetic fields (26) with the information. As the RF currents (24) and/or electromagnetic fields (26) reach everywhere within, on and in close proximity to the vehicle the information is communicated throughout.

Un système d'excitateur (1, 2) est capable de communiquer des informations entre une unité d'excitateur (10) et une ou plusieurs unités distantes (12) ou entre les unités d'excitateurs multiples (10). Ces unités d'excitateurs multiples (10) peuvent comprendre des dispositifs excitateurs de type sans fil tels que des excitateurs d'optimum (14) et peuvent comprendre aussi des dispositifs excitateurs de type équivalent tels que les excitateurs à connexion directe (16). Les dispositifs excitateurs (14, 16) injectent ou extraient les courants RF (24) dans la carrosserie métallique (22) d'un véhicule. Les unités distantes (12) couplent les champs électromagnétiques (26) à la carrosserie métallique (22) du véhicule. Les informations s'échangent avec les dispositifs excitateurs (14, 16) via des équipements de communications (20) qui modulent ou démodulent les courants RF (24) et/ou les champs électromagnétiques (26) avec les informations. Comme les courants RF (24) et/ou les champs électromagnétiques (26) pénètrent partout dans le véhicule ou directement ou à proximité de celui-ci, les informations sont communiquées de façon extensive.
