PURPOSE: An apparatus for preventing data errors in a WLL(Wireless Local Loop) system is provided to prevent the discontinuation of service by detecting and removing the error of transmitting data generated when a channel card is disconnected or an abnormal channel card is operated. CONSTITUTION: An apparatus for preventing data errors in a WLL system consists of a channel card part(10), a demultiplexing access part(20), an addition part(30), a parity detection part(40), a control part(50), and an error detection and removing part(60). The channel card part(10) processes forward data and reverse data. The demultiplexing access part(20) demultiplexes a plurality of transmitting data. The addition part(30) adds the demultiplexed data. The parity detection part(40) detects the parity error of the transmitting data. The control part(50) manages the system. The error detection and removing part(60) detects and removes the error of the demultiplexed data.
