Chapter 1 TGR1900 Theory of Operation
1.1 Overview of the Router
The TGR1900 integrates a Switch, Firewall, NAT-Router and Wireless AP. The TGR1900
delivers exceptional range and speed, which can fully meet the need of home networks and
users demanding high networking performance.
The TGR1900 utilizes a high speed ARM CPU. The router provides up to 600Mbps (2.4GHz) +
1300Mbps (5GHz) wireless connection with wireless clients. It is compatible with IEEE 802.11a,
IEEE 802.11b, IEEE 802.11g, IEEE 802.11n and IEEE 802.11ac products. Multiple protection
measures include Wi-Fi Protected Access (WPA2-PSK), as well as advanced firewall
protection.
Management of the device is provided by Google cloud services. All of the system software
for the platform and specifically for the control of all radios is signed and authenticated at
every time of initialization (booting). Google will build and distribute upgrades using the same
secure boot mechanism.
