6.2 PHY

6.2.1 Description

The ATWINC1500B 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 20MHz bandwidth. Advanced

algorithms have been employed to achieve maximum throughput in a real world communication

environment with impairments and interference. The PHY implements all the required functions that

include FFT, filtering, FEC (Viterbi decoder), frequency, timing acquisition and tracking, channel

estimation and equalization, carrier sensing, clear channel assessment, and automatic gain control.

6.2.2 Features

The ATWINC1500B IEEE802.11 PHY supports the following functions:

• Single antenna 1x1 stream in 20MHz channels

• Supports IEEE 802.11b DSSS-CCK modulation: 1, 2, 5.5, 11Mbps

• Supports IEEE 802.11g OFDM modulation: 6, 9, 12,18, 24, 36, 48, 54Mbps

• Supports IEEE 802.11n HT modulations MCS0-7, 20MHz, 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, 72.2Mbps

• 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

6.3 Radio

This section presents information describing the properties and characteristics of the ATWINC15x0-

MR210xB 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

C with a derating of 2-3dB at boundary conditions.

Measurements were taken under typical conditions: VBATT=3.3V; VDDIO=3.3V; temperature: +25ºC
