CLEAR is one of wireless internet provider with WIMAX platform which allowing their subscribers in the entire of cities to get high speed internet access with average 3 to 6 Mbps and burst over 10 Mbps. With this speed, if you are a CLEAR WIMAX subscriber, you can do many things from your laptop or desktop such as stream movies, play online games and video chat on the go.

Wireless internet service what ever the platform they used either WIMAX, EVDO or HSDPA is mobile broadband service which has unstable connection.

UK is one of the few countries which adopted mobile broadband technology to provide high speed internet access for their subscribers and increase broadband coverage. 3 mobile and Orange are two mobile broadband providers which dominate the network coverage in UK. Broadband providers like 3-mobile, T-mobile, Orange, Vodafone, Virgin media and O2 provide mobile broadband service with maximum speed up to 7.2 Mbps and some providers up to 14.4 Mbps. There also a plan to upgrade the mobile broadband network to ha 4 Generation to offer a speed up t0 100 Mbps. Most of mobile broadband providers are using 2G, 3G and 4G, HSDPA (High Speed Downlink Packet Access) technologies to adopted reliable network. Mobile broadband dongleuniversal serial bus also know USB (universal
serial bus) modem is the common device to access mobile broadband service in UK

There are two dominant mobile broadband plans in UK, mobile broadband pay per month and mobile broadband pay as you go. In a monthly plan, mobile broadband subscribers get free mobile broadband dongle and sign up for 18 or 24 months contract. Meanwhile in a pay as you go service, mobile broadband subscribers should buy USB modem and will pay if they access to internet only. Subscribers which subscribe to mobile broadband pay per month and pas as you go will have the same speed and coverage. 3 mobile is one of mobile broadband providers which offer MiFi Service to allow some subscribers to share to the same network

Bakrie Connectivity with their new mobile broadband AHA is also doing the same to provide hybrid modem technology. With hybrid modem technology, Bakrie Connectivity subscribers will still access wireless internet service on CDMA 1x while they can not get EVDO signal on particular area. Basically hybrid modem technology permits us to select what network platform available on particular area. Hybrid modem technology by default will select the best network platform in this case CDMA Rev A or CDMA Rev B. Once its area can not covered by those signal but CDMA 1x is available then your internet connection will be served by CDMA1x platform.

Hybrid modem technology allows us to keep connected with any available network. There are also modem technology which built with single technology platform either CDMA or EVDO platform. In such modem, once an area get no EVDO signal then a modem technology with CDMA platform is useless and vice versa. Mobile broadband providers for some reasons such as modem tariff. Bakrie Connectivity with their mobile broadband service called AHA provided such modem technology as well

To have high performance of mobile broadband service either 3G, EVDO or WIMAX service, mobile broadband provider should do many efforts on the telecommunication networks. Data optimization is one of the important things need to be executed on the telecommunication networks with many strategies and scenarios. Since mobile broadband service requires high bandwidth utilization, optimization on transport layer will affect to the entire of mobile broadband performance.

Data optimization on transport layer includes replacing the current low capacity of transmission network into higher capacity. Traditional network to serve traditional service (voice and SMS) will require several E1 transmissions to connect one BTS to the BSC. To meet to requirement on mobile broadband service, this connection should be upgraded to the higher capacity link e.g. optical fiber, SDH/SONET since there will be huge traffic will flow on this transport layer from the mobile broadband customer that may come together at the same time. Data optimization on this transport layer should be planned preciously and detailed. Some areas where mobile broadband customer is very significant should have bigger capacity on transport layer rather than rural area

Telecommunication network

Another part of telecommunication network which should be optimized to have affordable mobile broadband service is technology platform which serving mobile broadband service. Evolution on telecommunication technology should be planned integrated by utilizing current technology. Mobile broadband provider with 3G platform should plan to migrate to the 4G technology as the next platform. Meanwhile mobile broadband provider with EVDO Rev A platform should plan to migrate to the EVDO Rev B to produce high speed internet access than previous platform.

Data optimization in these strategies is very expensive and need long term vision to develop. More over, integrating with current telecommunication network is mandatory to reduce the cost. Actually the cheaper data optimization on mobile broadband service is available and some of mobile broadband provider implement it to provide optimum service

Wireless internet service includes CDMA and GSM platforms and its next generation network e.g. 3G, 4G and EVDO platforms. In terms of CDMA platform, there are many network elements of wireless internet service on the CDMA platform which involve on the data service call flow such AAA (Authentication, Authorization, and Accounting), Public Data Serving Node (PDSN), Home Local Register (HLR) and charging system

Wireless internet service call flow on Radio Frequency level

Mobile internet service session which comes from modem or mobile phone is the first initialization of the wireless internet service call flow. Radio Frequency will reserve the resource for this session if any resource is available. I case, radio frequency resource is full capacity then network busy notification will be sent to mobile internet service session

Wireless internet service call flow on Public Data Serving Node (PDSN)

Public Data Serving Node PDSN will process the entire of wireless internet service call flow. Public Data Serving Node PDSN will communicate with the Base Station Controller through the BSC PCF address (interface A10/A11). Public Data Serving Node (PDSN) connects to the AAA (Authentication, Authorization, and Accounting) servers, allocating IP address for the subscriber, maintaining the session including disconnect the session. Session which comes from BSC will be forwarded by PDSN to AAA server for authentication process at the first stage. While authentication process is pass, PDSN will allocate a IP address for the subscriber.

Wireless Internet Service Call flow on AAA (Authentication, Authorization, and Accounting)

Telecommunication companies could implement AAA (Authentication, Authorization, and Accounting) into two stages where authentication and accounting call flow could land into different network element. This mechanism has many benefits and can be implemented for many purpose such as accounting forwarding, proxy accounting etc. Authentication process will identify several of authentication information while session arrives on authentication server such as username, password, domain and IMSI (International Mobile Subscriber Identification). Authentication will acknowledge the authentication process if the session meets the requirement (username, password, domain and IMSI is valid). In case one or more of authentication information is not passed then authentication service will reject the session

Accounting process will be executed by charging system if telecommunication companies divide AAA (Authentication, Authorization, and Accounting) process into two stages
