Abstract:
1. An encoded information reading (EIR) terminal comprising: a microprocessor electrically coupled to a system/data bus; a memory communicatively coupled to said microprocessor; an EIR device selected from the group consisting of: a bar code reading device, an RFID reading device, and a card reading device, said EIR device configured to perform at least one of: outputting raw message data containing an encoded message and outputting decoded message data corresponding to an encoded message; a multi-band antenna; and a wireless communication interface comprising a radio frequency (RF) front end electrically coupled to said multi-band antenna; wherein said RF front end comprises a micro-electromechanical (MEMS) filter array, said filter array comprising one or more band-pass filter; wherein each band-pass filter of said MEMS filter array is electrically coupled to one of: a bias voltage source, an oscillating signal source; wherein said radio frequency front end is electrically coupled to at least one of: an analog-to-digital (A/D) converter electrically coupled to said system/data bus and a digital-to-analog (D/A) converter electrically coupled to said system/data bus; wherein said wireless communication interface is configured to perform at least one of: transmitting radio signals in one or more frequency regulatory domains, receiving radio signals in one or more frequency regulatory domains; wherein each band-pass filter of said MEMS filter array is electrically coupled to a switch, said switch being electrically coupled to one of: said bias voltage source, said oscillating signal source; wherein said microprocessor is configured to execute an operating frequency selector software program, said operating frequency selector software program configured to dynamically control said switch; and wherein said operating frequency selector software program is configured to dynamically control said switch based on estimated cost of data transmission.
