The Realtek RTL8185L, fully complying with IEEE 802.11a/b/g specifications, is a low-profile highly integrated cost-effective Wireless LAN network interface controller that integrates a Wireless LAN MAC and a Direct Sequence Spread Spectrum (DSSS) baseband processor onto one chip. To reduce protocol overhead, the RTL8185L supports Short InterFrame Space (SIFS) burst mode to send packets back-to-back. A protection mechanism prevents collisions among 802.11b nodes.

The RTL8185L implements Direct Sequence Spread Spectrum (DSSS), Complementary Code Keying (CCK), and Orthogonal Frequency Division Multiplexing (OFDM) baseband processing to support all IEEE 802.11a, 802.11b, and 802.11g data rates. Differential phase shift keying modulation schemes, DBPSK and DQPSK with data scrambling capability, are available, along with complementary code keying to provide data rates of 1, 2, 5.5, and 11Mbps, with long or short preamble. A high speed Fast Fourier Transform (FFT)/Inverse Fast Fourier Transform (IFFT), combined with BPSK, QPSK, 16QAM and 64QAM modulation of the individual subcarriers, provides data rates of 6, 9, 12, 18, 24, 36, 48 and 54Mbps, with rate compatible punctured convolutional coding with a coding rate of 1/2, 2/3, and 3/4. When in Realtek Turbo Mode, the RTL8185L provides a data rate of 72Mbps.
