Once telecommunications companies have decide to have mobile broadband service meanwhile previously they provide CDMA 1x or GPRS service than they need to prepare upgrading the network to support mobile broadband service. There are many network elements which should be upgraded such as Base Transceiver Station (BTS), Base Controller Station (BSC) and increasing the capacity of transmission media (backbone). Major upgrading on the core network element is mandatory to have the next generation network platform from previous one. Telecommunication companies with CDMA platform need to upgrade their network to EVDO platform to have mobile broadband service as the next network. Meanwhile telecommunication companies with CDMA platform should upgrade to 3G platform to have mobile broadband service
There are more network element should be upgraded to support mobile broadband service. Upgrading the capacity of the network interface on the router, switch/catalyst is the thing that can not be missed. If CDMA 1x or GPRS services require fast Ethernet which can handle maximum throughput 100 Mbps, mobile broadband service require 10 times of that capacity. Upgrading the network to have Giga byte throughout should be done to all of network element which involve to the mobile broadband service. Network interface of charging gateway also need to be upgrade to handle huge traffic that will hit the charging gateway. Each interface should be upgrade to the Giga byte Ethernet or optical fiber port. Huge traffic that will hit the network element is the main reason why network port should be upgrade to Giga byte or optical fiber port.
The network interface port on the servers which server part of mobile broadband service such as streaming and download contents, game services also should be upgraded to Giga byte or optical fiber port. The same way should be done on others network elements such as firewall, bandwidth management, cache engine etc. Upgrading the network to support mobile broadband service is to anticipate huge traffic which definitely will come and prevent network bottleneck.
