Mobile broadband providers should install many network elements in case this is the first deployment of mobile broadband or data service. For them who already have the data service such as CDMA 1x and GPRS, they only need to upgrade the network element to support mobile broadband service. Upgrading the network is including, upgrade the RF network capacity, increasing the international internet bandwidth capacity and upgrading the interface capacity on the network such as Router, Switch and Firewall
The primary of network elements that should be installed to have mobile broadband service includes, Public Data Servicing Node (PDSN), Authentication, Authorization and Accounting (AAA) Server, Charging Gateway, Internet Gateway. Meanwhile in core network, usually they already existed by utilizing current network elements such as BTS and BSC. Both of core network elements are used to be upgraded the license to support mobile broadband service. However if mobile broadband providers migrate to the different platform, suppose GPRS to WIMAX or CDMA 1x to WIMAX then they need to change the entire of network elements including BTS and BSC.
Others network elements of mobile broadband that should be considered are data comm networks such as router, switch and firewall. Even though they already existed in current network but we need to give more attention about the its capability to handle huge traffic that will come from mobile broadband subscribers. Transport network such as transmission media also needs to be upgraded to carry out huge traffic. Migrating to the optical network is the common strategy to prevent network bottle neck
Meanwhile in the border which will connect to the outside (internet and three parties), security system should be deployed to prevent undesired traffic from mobile broadband subscribers or outside (internet or three parties). Firewall, cache engine and Intrusion Prevention Systems (IPS) should be deployed to make sure the network security
