4.2 Hardware Architecture
This 802.11b/g/n device is operating at 2.4 GHz ISM band, it supports 20 MHz and 40 MHz
(optional) channels.
The WiFi design is based on Broadcom BCM4319 chipset.
The Broadcom BCM4319 is a highly integrated single chip solution for 2.4GHz 802.11n-ready wireless
local area network that enables a high performance 1X1 configuration for wireless station maximum
throughput and range, it integrated a multi-protocol MAC, baseband processor, ADC and DAC
converters, 1X1 radio transceiver, RF switch in all-CMOS device.
