Mobile Broadband modems are required by broadband providers to increase subscriber’s growth. Actually they can get broadband modem on the market but sometimes broadband providers offer more benefit while subscriber buy broadband modem provided by broadband providers. This broadband modem either 3G modems or EVDO modems are locked from others mobile network providers. Locked means that the modem can not be used to others SIM card from others network providers. Unlocking broadband modem means that this modem can be used with different SIM card. Typically, broadband modems are divided into Dongle (USB stick) and Data card. Dongle (USB stick) is the popular broadband modem provided by broadband providers

There are several broadband modems which used to be unlocked and can be used to different network such as Huawei, Three and T-Mobile. Huawei Modem is the common modems will be locked by some unlock modem providers due to Huawei supplies all networks with 3G data card including O2, Three, T-Mobile and Vodafone as well. In Huawei cases, unlocking the modem can be done by remove the networks lock on Huawei Data cards by providing the network unlock for the device. Several Huawei modem types which can be unlocked and can be used to several network such as Three, T-Mobile and Huawei are E156, E156G, E160, E160G, E169G, E170, E172, E176, E180, E182E, E196, E270, E271, E272, E510, E612, E618, E620, E630, E630+ , E660.

Modems unlocking can be done by several types and most of them are locked by unlocking code and unlocking by software. To generate unlock code, modem unlock provider requires your IMEI number. Meanwhile unlock by software, you should connect to your PC and running the unlocking software. Several 3G modems that can be locked by code are some 3G modems made by Huawei, Vodafone, Three, Orange, T-Mobile and O2 and they are modems and Dongles.

Mobile broadband comparison: EVDO and HSDPA

engineer — Thu, 08 Jul 2010 09:39:13 +0000

Mobile broadband comparison will lead broadband provider to select which one the best network suit to their network. If mobile broadband provider wants to compare EVDO and HSDPA service and select which one the best technology they can deploy, some parameters they need to consider while compare both are: What current technology they are deploying. It will take much investment while broadband provider migrates to the next generation network. Upgrading the current technology to the next generation network is the best way to reduce investment instead of replacing the entire of current network.

The next parameter while they are doing mobile broadband comparison before deploying is availability of support of mobile broadband service such as support system from the manufactures. Then we compare which the next generation network having full support system to maintain the network. Broadband provider needs also to compare each of manufacture that will support your service. The things they need to consider is how they can meet your requirement to deploy your broadband network. Broadband provider also needs to compare each of manufactures to make sure that each of mobile broadband network elements will work with others manufactures. Network interoperability is the common issue while they already deployed network with various manufactures on the same network

The next parameter when you are doing mobile broadband comparison before deploying network infrastructures is network equipment that will be used by subscribers such as USB modem, Stick modem, dongle, laptop, card and high end mobile phone which support 3G network. More end user equipment available in the market, mobile broadband provider will have more potential subscriber while launch the service. We need to compare which the most modem and dongle used by subscriber in the market and whether they are open market or belong to particular mobile broadband provider exclusively. Mobile broadband comparison also needs to be done by mobile broadband user to determine which the best mobile broadband service they will buy

Hybrid modem technology: Bakrie Connectivity AHA modem

engineer — Mon, 28 Jun 2010 00:33:48 +0000

Mobile broadband providers which already upgraded their network platform will still keep old network and provided the old service to their subscribers. For example CDMA mobile providers which already upgrade to the EVDO Rev A or EVDO Rev B or GSM network platform to 3G or 4G. They will serve at least 2 wireless internet service, CDMA 1x and EVDO service. The main reason due to it is need high cost investment to replace traditional network (CDMA or GSM) to the new one (CDMA Rev A or CDMA Rev B). Therefore they will provide hybrid modem technology to support both network platforms to their wireless internet subscribers.

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

Bakrie Connectivity introduces AHA broadband service with EVDO technology

engineer — Fri, 25 Jun 2010 16:18:28 +0000

Bakrie Connectivity as the Bakrie Telecom subsidiary introduces mobile broadband service product called AHA. AHA is Broadband Wireless Access (BWA) which supported by EVDO technology. With AHA introduction, Bakrie Connectivity enrich mobile broadband service with EVDO technology in Indonesia market after Smart Telecom which already launched since last year.

Mobile broadband technology is usually divided into two type, fixed line technology and wireless technology. Mobile broadband technology with fixed line requires broadband provider to provide direct connection from their core network to subscribers. Cable modem and xDSL (Digital Subscriber Line) is some of mobile broadband technology which using fixed line technology. Both services are using fiber coax cable and twisted copper. Meanwhile mobile broadband technology with wireless technology refers to technology that use point to point or point to multipoint connection from broadband provider and subscribers. Broadband wireless technology is using microwave in various frequency between 2.5 to 45 Ghz. EVDO services which launched by Bakrie Connectivity with the product called AHA is one of broadband technology which using wireless technology.

Broadband technology using wireless technology is growing very fast since giving high mobility and more value added for subscribers. Beside EVDO technology which used by Bakrie Connectivity their product called AHA, WIMAX is another broadband technology which using wireless technology. WIMAX has two types, line of sight (LOS) and non line of site (NLOS). The lost WIMAX system is point to point operation and it is much better than NLOS. However, LOS system did not facilitate to large broadband subscriber. Meanwhile NLOS system is point to multipoint operation which allows many subscribers.

Broadband technology such as EVDO and WIMAX required high resource capacity on the network. Bakrie Connectivity as the new mobile broadband provider with their product AHA moment should provide those much resource to support high speed internet access for their subscribers

EVDO – Evolution Data Only/Optimized

engineer — Thu, 17 Jun 2010 15:16:56 +0000

Broadband provider should consider others alternative technology to provide wider service coverage instead of traditional service such as cable and DSL. It depending on the current wireless network they have, EVDO – Evolution Data Only/Evolution Data Optimized is one option for CDMA platform. With EVDO platform, mobile broadband subscriber could have high speed internet access in many areas, any where and any time they want to access internet, download large file etc. EVDO – Evolution Data Only/Optimized is the next generation of CDMA 1xRTT and deployed to provide greater speed than CDMA 1x RTT which only have speed 50 Kbps – 100 Kbps (burst to 144 Kbps).

There are several platforms on EVDO – Evolution Data Only/Optimized which indicating the capability to download and upload:

EVDO Rev 0: can provide 400kbps-1000kbps to download (bursts up to 2.0Mbps) and 50kbps-100kbps to upload (bursts to 144Kbps)
EVDO Rev A: can provide 600Kbps-1,400Kbps to download (bursts to 3.1Mbps), and 500Kbps-800Kbps to upload (bursts to 1.8Mbps)
EVDO Rev B: up to 9.3 Mbps to download and 5.4 Mbps to upload

EVDO – Evolution Data Only/Optimized is working on CDMA network. Mobile provider with CDMA platform can utilize their traditional network to deploy EVDO (Evolution Data Only/Optimized service). They can integrate current network with EVDO platform. They only need to upgrade some network element to support EVDO platform such as AAA and PDSN itself.

Deploying EVDO – Evolution Data Only/Optimized is the thing that should be prioritized by mobile provider with CDMA platform as at the same time huge network migration to offer high speed internet access happens at many mobile providers either on GSM platform and WIMAX.

EVDO call flow: PDSN to Accounting server

engineer — Thu, 10 Jun 2010 09:49:55 +0000

Two nodes which have the main function to the EVDO call flow is PDSN and accounting server. Public Data Service Node (PDSN) is responsible to all the process related to data service session such handling Point to Point Protocol (PPP) session, allocation IP Pool, processing authentication authorization and accounting (AAA) process etc. meanwhile accounting server is responsible to the charging process of EVDO service. Accounting server will rate to any EVDO service packages and deduct subscriber balance. To execute this process, accounting server need to Intelligent Network (IN)

EVDO call flow on PDSN to accounting is related to charging purpose. This call flow describes how the session from EVDO subscriber comes to PDSN is happening and how the data call reach the accounting server and finally how the accounting server deduct the balance from Intelligent Network (IN). On the EVDO call flow, PDSN will receive accounting request from subscriber to accounting server. Usually PDSN will have more than 1 accounting servers. Some PDSN can do prioritizing and some PDSN can have more than one accounting server per domain. Accounting request which comes to PDSN then will be forwarded to the proper accounting server suppose primary accounting server. Then accounting server will check the DN subscriber whether they have sufficient right to access EVDO or not. If the user has sufficient rights then accounting server will response to PDSN for this session

The next step of EVDO call flow while accounting server responses the session is query the balance status to Intelligent Network (IN) before allowed to access EVDO service. There is particular protocol used by accounting server to check the status and reserve balance from IN. some accounting server will reserve a mount of balance before subscriber access the EVDO service. Since there are two types of EVDO service, prepaid and postpaid subscriber then there will be different call flow on the deduction process. The next step of EVDO call flow once the query and reservation balance to IN is complete is flowing traffic and service from subscriber to destination

The failure point of Value Added Service (VAS): Application programming interface (API) Facebook

engineer — Sun, 25 Apr 2010 17:36:47 +0000

Telecommunication companies that offering Facebook application as the part of Value Added Service (VAS) either on mobile broadband service such EVDO, 3G and Wimax should anticipate the changing on Application programming interface (API) by Facebook it self. This could happened especially on mobile facebook developer which using open source Facebook Java Application programming interface (API). Telecommunication Company which plan to provide Facebook application on the bundling mobile phone should deployseveral network elements and application client server to accommodate such Value Added Service (VAS)

To deploy Facebook application on such VAS, there are 2 components that should be deployed. The first is the Facebook client which will be inserted to the mobile phone with Facebook application. The second is middleware server which response any request comes from facebook client to facebook.com. Middleware server should interact with facebook.com so facebook client (mobile phone user) can generate facebook application and can do many activities there such as updating the status, commenting and change the profile. To interact with facebook.com, middleware server use Facebook Java Application programming interface (API) protocol provided by facebook.com itself.

Due to huge traffic especially the traffic comes from mobile facebook application trigged facebook.com to keep updating and changing the open source Java Application programming interface (API) protocol. This changing should be anticipated by mobile developer which responsible on middleware server and synchronize their facebook Java Application programming interface (API) with the new changing. More often, the changing on Facebook API is minor which means that only several sub modules were changed but it is still impacted to the customers experiences while they accessing facebook through mobile phone. The impact of API changing which did not synchronized on midlleware server could be time out response while mobile user tries to access facebook.com. Facebook mobile developer should anticipate this API changing that may come anytime.
