1.1INTRODUCTION
The WiMAX Outdoor CPE with router/Bridge functionality provides WiMAX connectivity to wired
LAN networks. The CPE functions as a WiMAX gateway providing wired and wireless broadband
Internet access services through connection with a WiMAX base station. The CPE is easily installed,
utilizing Plug and Play functionality. In addition to web-based configuration, users can update firmware,
simplifying installation and operation of the device. The CPE operates in Router mode and Bridge
mode, both providing Internet access:
1.1.1ROUTERMODE
In Router mode, the internal IP address is acquired through dynamic host configuration protocol
(DHCP), static IP address, or PPPoE connection to the WiMAX base station. With enabled
DHCP service, connected PCs and notebooks can acquire addresses from the CPE.
A CPE deployed for operation in the router mode is basically used to provide a gateway to hosts
on a local area network where the CPE hides all the traffic originating from the LAN behind its
IP address which is assigned from the public domain, which makes the traffic appear as if it’s
originating from the CPE itself. A router CPE implements Network Address Port Translation
protocol (NAPT).
1.1.2BRIDGEMODE
This mode requires minimal presetting, with the internal IP address configured in the same or
different network segment as the WiMAX base station. Bridging is a forwarding technique used
in packet-switched computer networks.
A CPE deployed for operation in the bridge mode is basically used to provide Ethernet service to
enterprise customer locations. An enterprise location has a CPE with an Ethernet interface that
could support one or many user hosts in the local network through a switch. CPE supports both
IP and Ethernet CS. If Ethernet CS is supported by the network then Layer 2 connectivity can be
established between SS and CSN. In this case, the network service to the enterprise customer is
an Ethernet service from the core network all the way to the enterprise MS.
