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

Transport technology of mobile internet service

engineer — Tue, 16 Feb 2010 16:06:28 +0000

Transport technology

Transport technology means technologies which utilize to carry out the traffic, mobile internet service traffic from mobile internet subscriber to internet gateway. Transport technology responsible to deliver huge traffic which should come from mobile internet service especially on 3G, EVDO and WIMAX services

Types of transport technologies

Telecommunication companies used to used optical fiber, SONET/SDH and satellite as the transport technologies to support high traffic utilization on mobile internet service. Optical fiber, SONET/SDH and satellite used to utilize to deliver the traffic on the core network

Optical Fiber

There are two types of optical fibers, single mode and multi mode fibers. Single mode has a small core rather than multi mode. Single mode fiber forces the light waves to stay on the same path/mode. Single mode fiber keeps the light going farther before they need to be amplified. Meanwhile multi mode fiber has much larger core than single mode. Multi mode fiber signal can not as far before they need to be amplified

SONET/SDH

Synchronous Digital Hierarchy (SDH) and Synchronous Optical Network (SONET) nodes are known as Add Drop Multiplexers (ADMs). SONET was developed at United Stated and SHD in European. SONET can deliver the packet up to 50 Mbps meanwhile SDH 150 Mps

Satellite

Telecommunication companies will utilize satellite technology for secondary link and will be delivered the traffic while primary link (optical fiber) goes down. There are two types of satellite technology, active and passive. A passive satellite only reflects received radio signals back to earth. An active satellite acts as a repeater; it amplifies signals received and then retransmits them back to earth.

PSTN (Fix) vs GSM (Mobile) communications

engineer — Fri, 29 Jan 2010 15:50:18 +0000

It was that Public Switched Telephone Network (PSTN) is the only one option for people to make communication with someone else. Few years later, technology was changing and people prefer to use mobile communication (GSM) rather then PSTN. The main reason is mobile communication is giving more flexibility rather than fix communication (PSTN). Mobile communication (GSM) support their activities much better rather fix communication (PSTN). As the result, now days we can see mobile communication (GSM) is growing faster rather than fix communication (PSTN)

From the technology perspective, growth of mobile communication (GSM) infrastructures is giving more benefit since they have flexibility and more simple during deployment rather than fix communication (PSTN) infrastructures. Telecommunication company which plan to deploy telecommunication network with mobile platform such as GSM, CDMA and 3G will invest many kind of telecommunication infrastructures which upgradeable, high compatibility with others vendor and high availability of resource to support many service such as mobile internet service. We can not find the same things right now if we will deploy the same telecommunication network with fix platform such as Public Switched Telephone Network (PSTN)

Evolution of telecommunication technology reduce inefficiency equipment while deployment which used to happen on fix communication platform (PSTN) such as cabling on each termination point. As we know that Public Switched Telephone Network (PSTN) is having a lot of cabling connection from one point to another one. On the Public Switched Telephone Network (PSTN) service, if Telecommunication Company has 1000 subscribers on particular area means that they should run 1000 peer cables from terminal cable point to each of subscriber home

We will not find the same thing on the mobile communication (GSM, CDMA or 3G). Telecommunication Company with mobile platform will deploy Base Transceiver Station (BTS) on particular area to cover people who want to make a mobile communication at that area. They will upgrade the capacity while they face lack of resource at that area with simple way and faster. The same thing will happen to all services including mobile internet service. Meanwhile on the fix communication service such as Public Switched Telephone Network (PSTN), Telecommunication Company will face big issue once they want to upgrade the capacity at the same area.

Beside, people begin to leave Public Switched Telephone Network (PSTN) service for personal purpose, the new technology is created to replace the old one which mean that old technology should be replaced. In the next few years, we will find Public Switched Telephone Network (PSTN) service no more

engineer — Sat, 16 Jan 2010 17:44:46 +0000

High demand on BlackBerry services is responded by each telecommunication companies which offer BlackBerry service to provide high technology to enrich to service. Various packages is also given by each telecommunication companies to spoil mobile telecommunication subscribers. As the result, almost each of telecommunication companies offers BlackBerry service either GSM or CDMA platform. Telecommunication companies companies in Indonesia are also doing the same despite of mobile internet service such as 3G and EVDO. BlackBerry technology to support the service is the key point to make sure that BlackBerry service is running properly. BlackBerry technology used to divided into BIS (BlackBerry Internet Service) and BES (BlackBerry Enterprise Service)

A BIS (BlackBerry Internet Service) is giving high speed mobile internet service access either through 3G or EVDO platform. Meanwhile BES (BlackBerry Enterprise Service) is providing a service which allows mobile telecommunication subscriber to access their internal corporate network. Telecommunication companies are running the server on the BIS (BlackBerry Internet Service). Each of data which coming to handheld is encrypted data and high security level. Telecommunication companies assign which kind of application will be available on the BlackBerry mobile phone. Meanwhile on the BES (BlackBerry Enterprise Service), the buyer corporate responsible to run the server

A BIS (BlackBerry Internet Service) connect the mobile telecommunication subscriber with their mobile phone BlackBerry to telecommunication companies through internet. Meanwhile BES (BlackBerry Enterprise Service) connects mobile phone BlackBerry to corporate server.

BIS (BlackBerry Internet Service) is a service which used to used by individual mobile telecommunication subscribers and small corporate to support many kind of business processes especially push mail service. In order to receive email, the mail server should support Post Office Protocol (POP3) and Internet Message Access Protocol (IMAP). Email will be received in about 30 seconds to 20 minutes and BIS (BlackBerry Internet Service support to have accounts up to 10

BES (BlackBerry Enterprise Service) is used to use by middle and up corporate to support many kind of activities. It is like a PC. BES (BlackBerry Enterprise Service) support to Microsoft exchange, Lotus and Novell servers. The benefits of BES (BlackBerry Enterprise Service) is real time push mail, contact and task compared to BIS (BlackBerry Internet Service) which has a delay

Migrating to the next technology: CDMA1x to EVDO

engineer — Sat, 05 Dec 2009 18:31:37 +0000

To meet mobile telecommunication subscribers which always grow up, each of telecommunication companies should plan their telecommunication infrastructures to have smooth processing while they should migrate to the next technology. High demand on broadband internet service either 3G or EVDO service is giving new opportunity for each telecommunication companies to provide broadband internet service instead of traditional wireless internet service e.g. CDMA 1x Rtt and GPRS. High demand on broadband internet service is also giving a challenge for each telecommunication companies especially to provide smooth migration from the traditional network to the next generation network. There are many things need to be prepare once telecommunication plan to migrate current technology to the next technology generation.

The first thing, they should decide which the next technology proper to the current one. Suppose, telecommunication companies have CDMA platform and CDMA 1xRtt is the technology to provide wireless internet service, then the proper next technology is EVDO (Evolution Data Only/Optimized). CDMA 1xRtt technology will give limited speed (153 kbps) to wireless internet subscriber. It is not recommended speed to compete with telecommunication companies which offer broadband internet service with 3G platform. Migrating to the EVDO technology is the best solution to give high speed internet experience to the mobile internet service

The second thing is trial EVDO technology to the existing CDMA 1xRtt platform. Trial is intended to identify whether any interoperability issue between CDMA 1xRtt with EVDO platform. Usually telecommunication companies will assign particular Base Transceiver Station (BTS) and Base Station Controller (BSC) with Public Data Service Node (PDSN) which already have EVDO license. EVDO platform should give high speed internet experience up to 2.7 Mbps while testing. EVDO is the next generation of CDMA 1x platform and it means there will be no significant changing on the current telecommunication infrastructure while they deploy EVDO platform

The third is upgrading the current CDMA 1x platform to the EVDO platform. EVDO is high speed internet access which requires high capacity on each network element which supports it. Network element which should be upgraded to the high capacities is Base Transceiver Station (BTS), backbone transmission and internet gateway.

Evolution of telecommunication technology to support Data Service

engineer — Mon, 23 Nov 2009 03:13:22 +0000

Telecommunication companies should take some necessary action while they provide Data Service to their mobile telecommunication subscribers including migrate the current telecommunication technology to the latest one. Data Service requires subscriber satisfaction and to meet this requirement high speed internet access experience will be the first priority while subscribers decide to use Data Service provided by telecommunication companies. Evolution of telecommunication technology in Indonesia is running very well and there are many implemented the latest telecommunication technology there.

1. Internet access through Public Switching Telephone Network (PSTN)

It was there is only one telecommunication service which only provided Data Service through Public Switching Telephone Network (PSTN) in Indonesia. Therefore Data Service was provided refer PSTN service. It was that telecommunication companies provided dial up connection while subscriber want to access internet service with has limited bandwidth (64 kbps)

Then it was upgraded to the latest DSL technology such as DSL (Digital Subscriber Line) such as ADSL (Asymmetric Digital Subscriber Line), SDSL (Symmetric DSL), HDSL (High Data bit rate DSL), and VDSL etc. Telkom is one of the telecommunication companies in Indonesia which provided Data Service with xDSL technology

2. CDMA1x 2000 and GPRS

CMDA 1x 2000 and GPRS are giving very limited internet access (115 kbps). CDMA1x 2000 and GPRS are the first Data Service provided by telecommunication companies while GSM and CDMA platforms introduced in Indonesia. In these platforms, mobile telecommunication subscriber will still face slow speed while accessing internet service especially during peak hour. Telecommunication companies usually did not separate between voice and data channel that is why CDMA1x 2000 and GPRS is getting slow speed. Bakrie Telecom, Smart Telecom and Starone are providing CDMA1x 2000 to their subscribers. Meanwhile Telkomsel, XL and Indosat are still providing GPRS service even though they already 3G service

3. 3G service

Next evolution of telecommunication technology on the GSM platform is 3G service which giving broadband internet access to the subscriber up to 7 Mbps. Telkomsel, XL and Indosat are telecommunication companies which provided 3G service

4. EVDO service

EVDO is new evolution of telecommunication technology on the CDMA platform. EVDO is giving broadband internet access as 3G services which up to 7 Mbps. Smart Telecom is the only telecommunication company in Indonesia which provided EVDO service

5. WIMAX Service

WIMAX service will come soon in Indonesia. There are some new telecommunication companies and existing one will provide WIMAX service and

Optical Fiber, SDH and Satellite transmission

engineer — Mon, 09 Nov 2009 18:22:22 +0000

Telecommunication companies which offered broadband internet service to the mobile telecommunication subscriber should plan carefully to the entire of data service infrastructures especially to the international internet bandwidth and how they will reach it. Rich telecommunication companies used to have one or more media transmissions to reach international internet gateway. By deploying media transmission to reach international internet gateway, meaning telecommunication comapanies have invested the backbone link that will be needed by others telecommunication companies and service provider such as Internet Service Provider (ISP)

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
