The thesis deals with problems of navigation blind in buildings, where is not possibility navigation by GPS (Global Positioning System). This thesis contain resolution through the use of communication units, placed in floor of buildings. This comunication units, equipped with receiver and transmitter, can give direction for blind by send own identification to transceiver in speciál stick (the thesis does not contain solving of the stick), which can information blind of position. Two comunication unit solution are available, that differs by using component part. The main difference is in use control unit of circuit. First circuit use as control unit ATAR862-3 (microprocessor and transmitter in one case) and the second one use microprocessor ATmega 8L. Both component made by Atmel corporation. Circuit with ATmega 8L is more exacting on curent consumption, but solving this problem is available and communication unit has low pretensions and long life. The part of thesis is program, which solving communication protocol for no-problem communication between unit in floor and special stick.
