End of June 2010, First Media will introduce the first Wimax 4G Internet service in Indonesia. It will do if the test certificate successfully pocketed operation-worthy (ULO) from the Directorate of Standardization Ministry Kominfo DGPT.

The first launching in the form of soft launch will be held at First Media on Monday, June 28, 2010, in Lippo Karawaci, Tangerang, Banten.

The presence of technology Long Term Evolution (LTE) 4G cellular networks, had feared would make the service through a network Wimax Broadband Wireless Access (BWA), withered in the bud. However Menkominfo Tifatul Sembiring promise I will not ignore Wimax for LTE.

Worldwide Interoperability for Microwave Access (Wimax) should be implemented this year. In addition because the technology is ready, the service also has issued a lot of money for licensing fees.

WiMax is the most appropriate platform to bring broadband services in urban or rural. Target 50 million broadband users could be realized in 2015. But, unfortunately, less supported by the government.

Technology for Worldwide Interoperability Microwave Access (Wimax)) which is a broadband wireless access technology (broadband wireless access or BWA) with high-speed access and wide-reaching is predicted to grow more slowly in Indonesia.

"WiMAX does not have the mobility to provide a broadband connection to the remote villages in Indonesia," said Senior Director, Services, GSM Association (GSMA), Jaikishan Rajaraman in his press statement here on Monday.

Some telecommunications operators would be doing some intensive preparation.

One of the winning bidder BWA or Selection Based Local Fixed Network Using Packet Switched Radio Frequency Band 2.3 GHz for Wireless Broadband Service Needs (wireless broadband) technology WiMax 'fallen' alias operate principle licenses revoked.

It is a PT Internux. This company won the bidding Banten and Greater zone (zone 4) with PT First Media Tbk. Internux won a tender with a bid price of less than Rp 110 billion. Meanwhile, the price offered in the first rank of First Media is Rp 121.2 billion.

However, Internux then do not pay the total liabilities plus Radio Frequency BHP and penalties until the end of the specified time limit, ie, February 22, 2010.

The government plans to re-tender
Showed its seriousness to develop Broadband Wireless Access (BWA) in Indonesia, the government finally decided to hold a tender early last year which was marked by the signing of two ministerial regulations (Candy) and two Ministerial Decree (KM) by the Communication and Information Minister Muhammad Nuh.

But, unfortunately, up to the limit payments last chance on 26 April 2010, two consortia, namely the consortium of PT Rahajasa Media Internet on behalf of the Consortium for Wimax Indonesia (KWI) and the consortium of PT Comtronics Systems and PT Adiwarta Perdania, unable to meet their payment obligations.

Specifications 802.16 / m
IEEE 802.16 / m according to the cellular layer requirements of IMT Advanced Next Generation Mobile Networks. The features and technologies in IMT-Advanced are:
1. Design of a general nature worldwide
2. Suitable / compatible with layananan contained in the fixed networks
3. Have a good kulitas
4. Small terminals that can be used for broad usage.
5. Service capabilities of multimedia applications in a broad range.

Mobile WiMAX 802.16 / m is the 'air interface' which offers a new spectrum efficiency and throughput in accordance with the requirements of ITU for 4G technology development kedepannnya. IEEE 802.16 / m is to standardize data transmission speed is higher on mobile devices. Data speeds up to 1Gbps and possible distribution via wireless broadband access is an alternative to cable, DSL, and 3G. Broadband spectrum that is used in the frequency range from 2.3 GHz-3.5 GHz and the use of OFDM / OFDMA (Orthogonal Frequency Division Multiplexing Access). With the use of OFDM / OFDMA is considered to bring efficiency gains in terms of frequency bandwidth, coverage areas, installation and cost. Development by the IEEE 802.16 standardization began in March 2007 and scheduled for completion around the year 2009.

Two new wireless technologies are emerging seem to compete. WiMAX (Worldwide Interoperability for Microwave Access) was born earlier than LTE (Long Term Evolution). In the device and handset vendors support more readily than LTE, WiMAX in 2009. While LTE will be developed after the year 2010. Each of these technologies by the International Telecommunications Union (ITU) will be candidates for 4G network standards (at least 100 Mbps for data transfer) at least in the year 2009.

Mobile WiMAX is a wireless broadband solution that enables mobile and fixed network konfergensi broadband via an extensive radio access technology and flexible network architecture. Water interface on Mobile WiMAX applying Orthogonal Frequency Division Multiple Access (OFDMA) to obtain multi-path performance is better in the environment of Non Line Of Sight (NLOS). To support the growing bandwidth channel (scalable) from 1.25 MHz to 20 MHz, IEEE 802.16e introduces the Scalable-OFDMA (SOFDMA), Mobile Technical Group (MTG) on the WiMAX Forum is developing the Mobile WiMAX system profiles that enable mobile system configured

Mobile WiMAX based on IEEE 802.16e standard enables WiMAX systems applied to portable and mobile applications as well as fixed and nomadic. Mobile WiMAX introduces OFDMA technology (Orthogonal Frequency Division Multiple Multiple Access) and supports several other features to provide mobile broadband services for users in the state of motion up to speeds of 120 km / hr. These features include:

Government and local industry optimistic WiMax operators will be held for the Wimax internet service that is affordable, because the market economies of scale will be quickly achieved.

Suhono Harso Supangkat, special staff Minister for Communications and Information Technology (Communication and Information Minister), said the local industry does not need to worry too much for responding to the high costs that are borne by the operator of the tender results.

Base Station (BS)
Element / WiMAX devices generally consist of BS in the center and the CPE at the customer side. However there is still an additional devices like antennas, cables and other accessories. Is a device transceiver (transmitter and receiver) that is usually installed one location (colocated) with a network of Internet Protocol (IP). From this base station will be connected to multiple CPE interfaces with media of radio waves (RF) WiMAX standard. BS components consist of:

Wireless anything what advantages and disadvantages?

Advantages:
When compared with dial-up
· Fast as broadband access
· IP numbers can change, such as Dial-Up Access
· Can access anywhere, provided in hotspot areas
· Cheap, fast and flexible
· Umbrella for many users in a hotspot.
Disadvantages:
· To use the WiFi we must exist in an area accessible by WiFi or the term 'hotspot'.
· WiFi coverage area is still small, the signal can not penetrate walls.
· Access Point is more easily infiltrated by a virus
· Bugged easy data exchange

WiMAX Benefits
Bandwidth and reach of WiMAX enabled technology is used in the following applications:
Linking one-Wi-Fi hotspot with other Wi-Fi hotspots and the Internet;
-Providing the latest broadband access alternatives other than cable and DSL;
-Provide telecommunications services and high speed data;
-Provide a different source for internet connectivity
as part of the company's sustainability plans. Where, if
a company has an Internet connection and cable-based
wireless, especially from different providers, such connectivity
will not be affected by the unavailability of the same services.

The need for connections, especially the Internet, which today has become even more secondary purposes in large cities, of course requires a good connection system, quickly and economically in order to utilize this facility will comfortably.
Two advances in today's Internet is a broadband (fast access) and wireless. WiMax standard combines these two things, provides high-speed Internet access via wireless connections. Because WiMAX can be accessed from a relatively far distance, this standard is
solution "recent" is effective for providing quick access to home users, and to create a hotspot-ho spots in places such as airports, campuses, and other small communities.
Based on the IEEE 802.16 standard, WiMAX uses architectural point-to-multipoint, which makes it an ideal way to provide quick access to the locations where cable-based connections will be very difficult and costly. WiMAX can also be a solution to provide fast access to suburban areas,
where high speed lines are not yet available. Compatibility is that WiMAX connections can be combined or transferred to LAN network or other wireless-based cable.

Huawei Technologies ("Huawei"), a leader in providing next generation telecommunications network solutions for operators around the world, today announced the successful hold 2.5 GHz WiMAX commercial network with coverage of Southeast Asia's largest for Globe Telecom, the first operator in the Philippines, which launched broadband services.

The government's move to clean up the frequency band is driven by inputs from the winning bidder WiMax 16.d and as a continuation of the steps that are no longer DGPT extend the permit on the tape that the allocation was intended for the implementation of these technologies.

WiMAX is an international standard of the BWA that refer to the IEEE 802.16 standard. This standard is then further developed by a joint forum between companies of the world who are members of the WiMAX Forum. IEEE 802.16 has several variants that are meant to develop performance and capabilities of WiMAX technology. Types of IEEE 802.16 standards can be seen in the following table:

WiMAX technology is the basis of the IEEE 802.16 standard that allows data transmission services for Broadband Wireless Access (BWA) as an alternative to cable access or DSL. This teknologi is an attempt to answer the need for greater data rate, wide coverage, and compatibility between components in the network. Large throughput of course be an initial target of developing an access technology. This is driven by the increasingly diverse communications applications made by customers. With high data rate allows the network to be able to handle various kinds of transmission, both the transmission of voice, data, and video. WiMAX Forum states that only one Base Station, in theory, reach the cell coverage radius of 50 km with the ability of the system can transmit data at speeds up to 75 Mbps per carrier for the type of fixed and portable access

Tender broadband wireless access (BWA) successfully held this year. WiMAX implementation was already in sight. However, one problem still prop. The government insists on using a version of WiMAX 802.16d, and 802.16e WiMAX industry request.

In Indonesia, Wimax is not as popular as Wi-Fi (Wireless Fidelity). But as one state licensed Wimax (Worldwide Interoperability Mobile Access), Indonesia has the authority to apply this technology to the telecommunications operators who have a mobile readiness readiness both in infrastructure and operational readiness-maintanance. Wimax wireless broadband access are expected to provide fresh air in the midst of the telecommunications industry competition and market needs.

Condition:
You have installed Vista and now you want XP to be on the second boot, and when you do, your Vista is not detected anymore, so you have to choose between re-format your drive and then install it again, or you repair Vista and it does not matter.

But you can run both in a dual boot without having to reformat.
Seetlah your Vista install, you install XP as the drive x:> (x is the drive of your choice, it could be d:, e:, etc..)

After you restart the computer, boot to Vista it does not appear, do not worry.
Next please you boot from the CD / DVD Vista, select repair the installation, now booting from the Vista works, but XP does not boot up, do not worry once again.

Place the CD / DVD drive your Vista in Vista (after entering the desktop) and go to the Start Menu, All Programs, Accessories and right click on the Command Prompt and click on Run As Administrator

Now follow some of the following commands:

Use Bootsect.exe to restore (restore) the MBR and boot from the Vista code that transfers control to the Windows Boot Manager program. To do so, enter the following command at the command prompt:

Drive: \ boot \ Bootsect.exe-NT60 All

In this command, Drive is the drive where the installation media is Windows Vista.

Use Bcdedit.exe to manually create entries in the BCD Boot.ini file for the earlier versions of OS Windows. To do so, enter the following command at the command prompt.

Note that you need to look at it again in the following command is that the Drive is the drive where Windows Vista installed.

Drive: \ Windows \ system32 \ bcdedit-create (NTLDR)-d "Description for earlier Windows version"

Note that the words "Description for earlier Windows version" you can change the text or any text. For example, you write it with "Windows XP" or "Windows Server 2003"

Drive: \ Windows \ system32 \ bcdedit-set (NTLDR) device partition = x:

Note that x: is the drive letter for the active partition.

Drive: \ Windows \ system32 \ bcdedit-set (NTLDR) path \ ntldrDrive: \ Windows \ system32 \ bcdedit-displayorder (NTLDR)

Restart your computer.

Good luck!
