Fiber-to-the-Antenna

Posted by James Donovan on February 22nd, 2012

Due to the high investment in new network infrastructure, mobile communications operators are tending to focus on operating costs (OPEX). The increasing number of cells and the parallel operation of different network technologies (GSM, UMTS, LTE) mean that the costs for operating and maintaining the network are also constantly rising. This trend is in stark contrast to stagnating turnovers caused by flat rates and falling call charges. The driving forces for turnover are now high-speed Internet, data services and media content.

Over the last decade, cell site architectures have been evolving from the legacy cell site architecture where large radios are located remote from the antennas, to an architecture wherein a separate RF portion of the radio can be located more closely to the antenna. This separation of the digital radio, BBU (Base Band Unit), from the analog radio, RRH (Remote Radio Head), allows for a reduction of the equipment foot print at the site and for a more efficient operation of the network. The next stage in the evolution of the site architecture is the actual integration of the radio into the antenna and the distribution of the radio functionality across the antenna elements. This is called an active antenna.

Conventional base systems use coaxial cables to transmit the high-frequency signal from the base station to the remote mast antenna. An advantage of remote radio systems is the use of optical fiber connections called FTTA (fiber-to-the-antenna) to link the RRH to the base station.

How can you best optimize your current infrastructure and adapt to these new technologies? What is the best method for adjusting existing tower components to meet new critical needs of deploying remote radio heads without overloading the tower? How do you ensure adequate fiber capacity that will enable you to grow beyond tomorrow while making sure CAPEX/OPEX costs don’t spiral out of control in the process?

At CommScope, we believe that the solution begins with the basics: your transmission line cable system. It is the core component of your infrastructure. Laying the groundwork for what comes next starts with a fiber optic infrastructure specifically designed for distributed remote radio head deployments.

Why is ISO 9001 2008 Important?

What is ISO 9001 2008?

ISO 9001 is an international quality management standard. It is rapidly becoming the most popular quality standard in the world. Thousands of organizations in over 100 countries have adopted it, and many more are in the process of doing so. 

Why? Because it controls quality. It saves money. Customers expect it. And competitors use it.

ISO 9001 applies to all types of organizations. It doesn't matter what size they are or what they do. It can help both product and service oriented organizations achieve standards of quality that are recognized and respected throughout the world.

ISO is the International Organization for Standardization. It is located in Switzerland and was established in 1947 to develop common international standards in many areas.

Its members come from over 150 national standards bodies. ISO's purpose is to facilitate international trade by providing a single set of standards that people everywhere would recognize and respect.

Why is ISO 9001 2008 Important?

ISO 9001 is important because of its orientation. While the content itself is useful and important, the content alone does not account for its widespread appeal. 

ISO 9001 is important because of its international orientation. Currently, ISO 9001 is supported by national standards bodies from more than 150 countries. This makes it the logical choice for any organization that does business internationally or that serves customers who demand an international standard of excellence.

ISO 9001 is also important because of its systemic orientation. We think this is crucial. Many people wrongly emphasize motivational and attitudinal factors. The assumption is that quality can only be created if workers are motivated and have the right attitude. This is fine, but it doesn't go far enough. Unless you institutionalize the right attitude by supporting it with the right policies, procedures, records, technologies, resources, and structures, you will never achieve the standards of quality that other organizations seem to be able to achieve. Unless you establish a quality attitude by creating a quality management system, you will never achieve a world-class standard of quality.

Finally, ensure you have a right partner which had been ISO 9001:2008 certified and we have it to ensure customer satistaction.

Namun pada fungsi yang lebih luas CCTV dapat dipergunakan sebagai alat untuk membantu perusahaan untuk meningkatkan bisnis pada perusahaan tersebut.

Bagaimana sebuah CCTV dapat meningkatkan bisnis sebuah perusahaan ? 

Pada kenyataannya pada saat sebuah perusahaan memasang sebuah CCTV pada sebuah gudang maupun kantor hanya sebagai pengawas agar tidak terjadi tindakan kriminal pada fasilitas perusahaan tersebut. Namun jika kita ingin memperdalam fungsi dari CCTV tersebut, CCTV dapat dipergunakan untuk mengawasi alur kerja yang telah ditetapkan. Apakah prosedur yang telah diterapkan oleh perusahaan telah berjalan dan apakah prosedur tersebut sudah berjalan secara efektif. Mungkin saja bila diamati dari hasil rekaman CCTV selama kurun waktu tertentu ditemukan bahwa terjadi kelebihan karyawan pada bagian/departemen tertentu dan direkomendasikan untuk pemindahaan ke divisi yang lain yang memerlukan karyawan tambahan.
 

Dari hasil evaluasi ini perusahaan dapat meningkatkan efektifitas pekerjaan yang secara otomatis akan membantu untuk meningkatkan efisiensi biaya. Selain itu, dapat meningkatkan efektifitas produksi pada sebuah pabrik tentunya.

Kami sebagai penyedia solusi IT dapat membantu Anda untuk memberikan solusi-solusi yang dapat meningkatkan bisnis anda di masa yang akan datang.

Is Your Network Ready?

Technology's changing everything from when, and on what device, we watch our favorite TV shows...how many devices are connected on our networks...to how we communicate and share content. Is your communication network ready for the challenges -- and opportunities -- ahead? CommScope shows you three key areas to focus your resources so you and your network will be ready for the future of technology.

Technology, Intelligence, Energy

Technology, Intelligence, Energy - Three words that probably best sum up the key challenges and opportunities for network infrastructures, whether they are wired or wireless.  As with most things in life today, it is all about the money. However the real opportunity is to find solutions, even if they cost a little more on day one, that can reap rewards that far exceed any extra paid.

It is clear that networks need to be ready and smarter to support all the smart devices, tablets, homes, data centers and video connected…all at once.

Networks need to be dynamic enough to stay ahead of the intelligence (management, monitoring, security) curves in the road and in the cloud.

And networks need to be powered efficiently enough to deliver the bandwidth to empower communication around the world…cost effectively.

In the midst of hard financial times around the world, it is still an exciting—yet challenging—time in our industry. There are opportunities…if we can overcome the challenges. This video highlights these challenges, opportunities and the potential for solutions.

Right now millions of people around the world are texting, tweeting, messaging, and posting…downloading apps, books, and music…uploading videos and photos…managing the business of life at home, at work, and on the go…sharing content, knowledge, and hope…and in some countries, enjoying access to networked communication for the first time.

It’s all made possible by the networks you build. At any given moment, these networks help people, businesses, and governments across the globe operate, expand, and connect.

What is the future of our industry in terms of bandwidth, technology, energy, and intelligence?  How will things change/have they changed already? What opportunities will it bring for all of us? And what challenges will we face on the way there?

PIM Happens – Why, What, When?

Posted by James Donovan on January 30th, 2012 |

For wireless cellular networks to achieve their full operating potential, each sector within the network must perform up to its design standard. When this does not occur, the economic impact to the service provider can be substantial:

• lost revenue at that site

• customer dissatisfaction and churn

• increased infrastructure cost

• reduction in cell site coverage area

To achieve the full operating potential of each node in the network, each radio frequency (RF) component and interconnection of the RF path components must be properly installed, verified and maintained to ensure optimum performance overtime.

Viewed from the RF perspective, to maximize performance it is essential that:

• the wireless carrier signals be efficiently propagated from the transmitter output through the RF path components with minimum loss and distortion

• upon receiving the RF signal from the mobile handset at the base-station antenna (BSA), the signal must be efficiently propagated back to the basestation receiver

• interference/noise at the base-station receiver within the frequency band of the handset uplink signals must be lower in magnitude than the system noise floor

There are more components than ever in the RF transmission path, including cables, connectors, amplifiers, antennas, and each additional component is another potential source of signal degradation. All of these components contribute to INCREASING system Insertion Loss and REDUCING the overall Return Loss value, which simply stated means “The system performance is getting worse”.

Wireless operators have invested and are investing a lot of money into 3G and 4G networks and will continue to do so for the next generation of technologies. These investments are often overlayed on the existing network, utilizing existing tower equipment such as coaxial feeder cable, filters and base station antennas. Steps need to be taken to avoid potential signal degradation that can result from overlays, especially when adding new frequency bands. Passive Intermodulation (PIM) is one of the causes of signal degradation, and the incidence and cost of PIM is no longer simply a nuisance—it is a critical threat to network efficiency, channel capacity, and bottom line profit.
