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.

Optical fiber and Satellite transmissions are the most transmission media which used to use by telecommunication companies to carry huge traffic from backbone network. With high capacity they can cater, optical fiber and satellite transmission will be the first option while telecommunication planning team decides to deploy telecommunication infrastructure.

There are many network elements which can split high transmission capacity of optical fiber into many small capacities e.g. E1 capacity (2 Mbps) and per time slot (64 kbps). Telecommunication manufacture (vendor) deploys such network element such as Synchronous Digital Hierarchy (SDH) to fulfill requirement from telecommunication companies which could manage the backbone traffic up to several Giga bytes. Telecommunication manufactures which already have deployed the SDH system and has been deployed on the wide market are Alcatel, Siemens, Nokia, Ericsson and NEC. They are produce high capability network element which connect to directly to optical fiber

Satellite transmission in alternative solution once telecommunication companies can not provided optical fiber for the backbone transmission or there is no E1 transmission via radio microwave to carry out low and middle traffic. Satellite transmission is high costly transmission media which will be the final second choice while optical fiber to carry out the huge backbone traffic is unavailable. Since the high cost to deploy satellite transmission, there will be a few of network provider which provide satellite transmission lease line.

Usually telecommunication companies which have international internet backbone will use one or more media transmission optical fiber, Synchronous Digital Hierarchy (SDH) and satellite transmission. Rich telecommunication companies will have one or more of them. It is very expensive to deploy optical fiber, SDH or Satellite transmission networks to reach international internet gateway but telecommunication companies will have a lot of benefits once they have installed optical fiber, SDH or Satellite transmission networks

1. Optical fiber network

Telecommunication companies should deploy optical fiber network from their HQ office to the international internet gateway. There could thousands kilometers of optical fiber they should run to reach international internet gateway. It is depending on type of optical fiber, this deploying require much investment. Deploying optical fiber network will gain huge backbone link which could be more 10 GBps (depending on the optical fiber type and infrastructure to support)

2. Synchronous Digital Hierarchy (SDH) network

SDH network is actually radio microwave transmission with high E1 capacity. SDH network reach up to 64 STM1 and it means there will be 64 x 63 x 2 Mbps. SDH has high flexibility rather than PDH (Plesiochronous Digital Hierarchy) where the speed allocation can be divided in to time slot bases. It is like on optical fiber network, deploying SDH network also spend much money and telecommunication companies should consider well before they deploy SDH network

3. Satellite transmission network

Satellite transmission has much delay response compared to optical fiber and SDH network. Usually telecommunication companies will use satellite transmission network for the back up link in case primary link (optical fiber or SHD networks) is getting problem. Satellite transmission network is the most expensive investment compared to optical fiber network or SDH networks

There are many ways to optimize wireless and broadband internet services instead of increase more international internet bandwidth. They are;

1. Applying data accelerator with client server platform

With data accelerator, wireless and broadband internet subscribers will have multiple choices to display the type of internet traffic they will receive on the laptop/computer. Data accelerator can improve the speed of internet access experienced by wireless and broadband internet subscriber while they use client software. Basically data accelerator is client server platform where the entire of internet traffic will be forwarded by server to international internet gateway and server will cache it. While wireless and broadband internet subscriber activate the client software, server will reduce and remove some unnecessary packets before subscriber receive the traffic. It is very important applying data accelerator to the wireless and broadband internet service to achieve stable connection and speed

2. Bandwidth management

Telecommunication companies can not manage the behavior of wireless and broadband internet service to limit the download file, real time streaming video (RTSP) and attaching huge file while sending e-mail. Telecommunication companies can not say to wireless and broadband internet service to limit them. What they can do is manage the bandwidth to the entire of purpose while subscriber access to the internet. Telecommunication companies used to will manage the total of international internet bandwidth they have and divide it into several segments. For example, telecommunication companies will limit download access to have only maximum 30 Mbps, http protocol will have 50 Mbps, and Real Time Streaming Video (RTSP) file will have 20 Mbps etc. Bandwidth management makes sure that each protocol and application will have dedicated bandwidth and they will be interrupted when one protocol or application was saturated

Data accelerator and Bandwidth Management will reduce many complaints of wireless and broadband internet service and give significant benefits to the wireless and broadband internet subscribers

High demand from mobile telecommunication subscribers on the mobile broadband internet service definitely produces more revenue to the telecommunication companies even though some of telecommunication companies campaigned cheap tariffs to one or more their telecommunication services especially to the data and voice services. To give better telecommunication services especially to the data and voice services e.g. mobile broadband internet service to the mobile telecommunication subscribers, telecommunication companies should make sure that telecommunication infrastructures able to handle huge traffic come from subscribers. Usually telecommunication companies will enhance their telecommunication infrastructure with many methods to optimize data and voice services such as:

1. Deploying VOIP service to handle long distance call

Once voice traffic increase very fast especially long distance call, telecommunication companies will face critical issue that is link transmission to carry out the traffic from mobile telecommunication subscribers. More over, usually telecommunication companies did not have transmission backbone such as optical or Synchronous Digital Hierarchy (SDH) networks. Deploying Voice over IP (VOIP) network to handle long distance call is a make sense solution. With the VOIP network, the same mount of link transmission could carry out more than four times traffic from mobile telecommunication service compared to traditional call

2. Applying data optimization on the data service environment

The main problem on data service e.g. mobile broadband internet service is issue on Radio Frequency (RF) capacity which reserve channels for data service from mobile telecommunication service especially to the telecommunication companies which did not dedicated allocation for data service. Beside RF issue, internet bandwidth also shares the problem on data service. Telecommunication companies used to optimize the entire of data service environment with data optimization which will be applied on the client (mobile telecommunication subscribers) or data service infrastructures. Data optimization could be inserting new device such as data accelerator and bandwidth management on the mobile broadband internet service.

The goal of deploying VOIP and applying data optimization is mobile telecommunication subscribers will experience better telecommunication services
