A method for programming a network transceiver, the method comprising the steps of: a) receiving RFID data from an RFID device (28, 40) in proximity to the network transceiver, said RFID data being received via an RFID antenna (38, 39) in communication with an RFID reader or an RFID memory positioned inside an electromagnetically shielding housing of the network transceiver, said RFID data defining an operating configuration of the network transceiver; and b) programming the network transceiver according to the operating configuration defined by the received RFID data; wherein the RFID antenna (38, 39) is positioned inside the electromagnetically shielding housing of the network transceiver; wherein the electromagnetically shielding housing comprises an aperture for allowing electromagnetic signals to pass therethrough; wherein a smart label or an internal/external RFID repeater is attached to the housing, wherein the smart label and the internal/external RFID repeater comprise: - an electromagnetic substrate configured with electrically conductive material or ferrite material, preferably completely covering the aperture, to attenuate electromagnetic emissions radiating through the aperture; - an internal RFID antenna (60, 90) at least partially protruding through the aperture; wherein the smart label further comprises: an RFID tag secured to or embedded in the substrate, the RFID tag including the internal RFID antenna and having stored thereon the RFID data defining the operating configuration of the network transceiver, the RFID tag acting as said RFID device (28, 40); and wherein the internal/external repeater further comprises: an external repeater RFID antenna, and a connection between the internal RFID antenna and the external repeater RFID antenna, the internal/external repeater relaying the RFID data from said RFID device (28, 40). a) receiving RFID data from an RFID device (28, 40) in proximity to the network transceiver, said RFID data being received via an RFID antenna (38, 39) in communication with an RFID reader or an RFID memory positioned inside an electromagnetically shielding housing of the network transceiver, said RFID data defining an operating configuration of the network transceiver; and b) programming the network transceiver according to the operating configuration defined by the received RFID data; - an electromagnetic substrate configured with electrically conductive material or ferrite material, preferably completely covering the aperture, to attenuate electromagnetic emissions radiating through the aperture; - an internal RFID antenna (60, 90) at least partially protruding through the aperture; wherein the smart label further comprises: an RFID tag secured to or embedded in the substrate, the RFID tag including the internal RFID antenna and having stored thereon the RFID data defining the operating configuration of the network transceiver, the RFID tag acting as said RFID device (28, 40); and wherein the internal/external repeater further comprises: an external repeater RFID antenna, and a connection between the internal RFID antenna and the external repeater RFID antenna, the internal/external repeater relaying the RFID data from said RFID device (28, 40).
