A programmable logic device (PLD) with a JTAG port, such as an FPGA, is provided with a wireless JTAG adapter to enable wireless communications. Multiple PLDs connected with wireless-to-JTAG adapters can be wirelessly linked in a network to form a large boundary-scan chain serial interface. To communicate with the PLDs having a wireless JTAG port, a host PC running application software is also equipped with a wireless transceiver.
