8.2 PHY
The ATWINC3400-MR210CA module WLAN PHY is designed to achieve reliable and power-efficient
physical layer communication specified by IEEE 802.11 b/g/n in single stream mode with 20 MHz
bandwidth. The advanced algorithms are used to achieve maximum throughput in a real world
communication environment with impairments and interference. The PHY implements all the required
functions such as Fast Fourier Transform (FFT), filtering, Forward Error Correction (FEC) that is a Viterbi
decoder, frequency, timing acquisition and tracking, channel estimation and equalization, carrier sensing,
clear channel assessment and automatic gain control.
Features
The IEEE 802.11 PHY supports the following functions:
Single antenna 1x1 stream in 20 MHz channels
Supports IEEE 802.11b DSSS-CCK modulation: 1, 2, 5.5, and 11 Mbps
Supports IEEE 802.11g OFDM modulation: 6, 9, 12,18, 24, 36, 48, and 54 Mbps
Supports IEEE 802.11n HT modulations MCS0-7, 20 MHz, 800 and 400ns guard interval: 6.5, 7.2,
13.0, 14.4, 19.5, 21.7, 26.0, 28.9, 39.0, 43.3, 52.0, 57.8, 58.5, 65.0, and 72.2 Mbps
IEEE 802.11n mixed mode operation
Per packet Tx power control
Advanced channel estimation/equalization, automatic gain control, CCA, carrier/symbol recovery
and frame detection
8.3 Radio
This section presents information describing the properties and characteristics of the ATWINC3400-
MR210CA and Wi-Fi radio transmit and receive performance capabilities of the device.
The performance measurements are taken at the RF pin assuming 50Ω impedance; the RF performance
is guaranteed for room temperature of 25
o
C with a derating of 2-3 dB at boundary conditions.
Measurements were taken under typical conditions: VBATT=3.3V; VDDIO=3.3V; temperature: +25ºC
