Servicios de Banda ancha y 3G

“Any place, Every where”

When wideband speech refers to a system for Internet connection and data transmission. Currently, broadband is one of the best options to enjoy as a data rate much higher than what happens with access via dial-up. In addition, broadband also maintains a permanent Internet access without interrupting the telephone line and resorting to external modems.

Cuando hablamos de ancho de banda nos referimos a la velocidad y capacidad de la transmisión de datos en una red. Dicho dato depende tanto del tipo de estructura que presenta la red como los dispositivos que soportan y emiten la señal. En el mercado existen varias tarifas, fijas las cuales brindan un servicio básico, limitado, y las dial up o Premium, las cuales ofrecen una conexión más rápida y estable a cierta red.

El funcionamiento de la banda ancha se basa en la utilización de tecnologías DSL y de cable módems. Sin embargo, en la actualidad, la tecnología WiFi, que no necesita cableado, está creciendo más y más, especialmente para suplir a aquellos usuarios que viven en áreas sin las tecnologías o capacidades necesarias para establecer complejos sistemas de cable módem. La fibra óptica, el material utilizado para la transmisión de datos en banda ancha, ha demostrado ser mucho más eficiente que el cobre y mucho más eficaz en relación a la velocidad posible adquirida.

Depende de gran manera tanto de los dispositivos emisores de la red, tanto como los receptores pues si existe un fuerte ancho de banda pero el dispositivo receptor cuenta con un adaptador ya sea inalámbrico como alámbrico de poca capacidad, la conexión se verá limitada, el ancho de banda siempre ira de la mano con una optima administración de los…...

3g Technology

...3G, short for third Generation, is a term used to represent the 3rd generation of mobile telecommunications technology. Also called Tri-Band 3G. This is a set of standards used for mobile devices and mobile telecommunication services and networks that comply with the International Mobile Telecommunications-2000 (IMT-2000) specifications by the International Telecommunication Union.[1] 3G finds application in wireless voice telephony, mobile Internet access, fixed wireless Internet access, video calls and mobile TV. Several telecommunications companies market wireless mobile Internet services as 3G, indicating that the advertised service is provided over a 3G wireless network. Services advertised as 3G are required to meet IMT-2000 technical standards, including standards for reliability and speed (data transfer rates). To meet the IMT-2000 standards, a system is required to provide peak data rates of at least 200 kbit/s (about 0.2 Mbit/s). However, many services advertised as 3G provide higher speed than the minimum technical requirements for a 3G service. Recent 3G releases, often denoted 3.5G and 3.75G, also provide mobile broadband access of several Mbit/s to smartphones and mobile modems in laptop computers. The following standards are typically branded 3G: the UMTS system, first offered in 2001, standardized by 3GPP, used primarily in Europe, Japan, China (however with a different radio interface) and other regions predominated by GSM 2G system infrastructure.

As are the hardware and software needed to create and secure the networks. Each location will be set up with its own Wireless local area connection and they will all utilize the Internet to provide a Wide Area connection for the company as a whole. LAN, WAN and Wireless technologies Local Area Networks, or LANs, are a grouping of computers networked together in a generally small geographic area. LAN technology refers to the hardware and software used to create a local area network. The most common wired methods are Ethernet and Token Ring, and WLAN technologies using IEEE 802.11. WAN or Wide Area Network technologies include ATM. TCP/IP, and Frame Relay to connect and transfer data across large distances. Using a cable such as an Ethernet cable computers on a LAN are required to share the network when passing data packets back and forth. Before sending data across the network each computer checks the line for other transmissions. If the line is clear the computer sends the data, if not the computer waits. This method is called CSMA/CD. Wireless LANs or WLANs use RF signals to transmit data across the network. Every computer on a wireless local area network share the same frequency and take turns sending data just like using a cable. Wireless LANs use CSMA/CA to check for an open line of communication to it......

3g Historically

...and other options. 3G is the network expansion which allowed direct internet connections, Wideband data access, simultaneous voice, data, music, and telephone, plus network based apps all rolled into one. 3G is the network which allows you to use the cell phone as a credit card. 4G is a network in the planning stages, although some companies say they are implementing parts of the 4G net now. 4G includes a network specification (engineer talk for basic requirement), for 100 megabit to 1 gigabit data transfer rates while highly mobile worldwide. It also includes high quality of service requirements for multimedia support (real time audio, high speed data, HDTV video content, mobile TV, etc). 4G is coming, but is not here yet, because the specs are still being worked over at the ITU (Intenational Telecom Union) in Geneva.  A 3G/4G network is one where the network meets all the 3G ITU Specifications, and also has upgraded to meet the 4g Specifications as they are ratified by the ITU. What they want to say when they Announce the 3G/4G Network is that they are ready for the future. Most engineers will tell you that they really mean they'll say anything to sell their phones.

A Generic Wan

...A generic wide area network uses the following components: Component | Description | WAN cloud | The WAN cloud is the collection of equipment that makes up the WAN network. The WAN cloud is owned and maintained by large telecommunications companies. It is represented as a cloud because the physical structure varies, and different networks with common connection points may overlap. Few people thoroughly understand where data goes as it is switched through the "cloud." What is important is that data goes in, travels through the line, and arrives at its destination. | Central Office (CO) | The central office is a switching facility connected to the WAN, and is the nearest point of presence for the WAN provider. It provides WAN-cloud entry and exit points. | Local loop | The local loop is the cable that extends from the central office to the customer location. The local loop is owned and maintained by the WAN service provider. Typically, it is UTP, but it can also be one or a combination of UTP, fiber optic, or other media. The local loop is often referred to as the "last mile" because it represents the last portion of the WAN up to the customer premises. | Demarcation point (demarc) | When you contract with a local exchange carrier (LEC) for data or telephone services, they install a physical cable and a termination jack onto your premises. The demarcation point is the line that marks the boundary between the telco equipment and the private network or telephone......

Technology of 3g

...3g or third generation mobile technology refers to the standards set by International Telecommunication Units (ITU). This technology allows mobile operators to offer more options to users including mobile broadband. 3G facilitates devices like mobile phones and mobile dongles to deliver broadband speed internet. Most new top of the range mobile phones are 3G enabled, making it easy to check emails and browse the web on the go. Internet use via mobile phones has been slow to take off but mobile broadband via dongles, has taken off extremely fast. Mobile broadband allows customers to browse the internet, email and download files, music and video clips from their laptops and PCs wherever there’s mobile coverage. 3G technology is made possible by two complementary technologies, HSDPA and HSUPA (high speeds downloads and upload packet access, respectively). These technologies enable mobile broadband users to access of up to 7.2 Mb downloads and uploads with speeds of up to 1.76 Mb via a mobile dongle, USB modem or data card which they plug into the USB port of their laptop or PC. 3G can offer speed up to 7.2 Mb as it uses the air waves more efficiently, than its predecessors such as 2G and GPRS which offered limited internet connectivity. The initial foundation of 3G can be traced back to 1970s when Luigi Galvani investigated the nature and effects of electrophysiology, and began experiments with muscular stimulation by electrical means.

...NT2799: Week 3 WAN Management Exercise 3.1 Michael K Higdon Critical Components of a Project In the following document you will be given an overview of how budget and schedule are critical components of all projects that you encounter in your everyday business. I am going to give you some ideas and concepts that you can use to alter the outcome of said project. I am not saying that my ways are the best ways to be successful in your project management needs. I am going to communicate what has worked for me in the areas of Quality, Time and Cost. In project management there is something that we use called “The Project Management Triangle”? It uses these three key variables as the guidelines in building your projects success. I once overheard a client at my job telling someone that they can have the project done fast, good and then there is cheap. You have to pick two points of the triangle that you want. You can never have all three. I do not believe this philosophy when it comes to success in the business field; I think that you can have all three. When breaking down a project triangle let me give you some background. Fast usually refers to the timeline in getting the job done that has been asked. When you talk about Good, this refers to the quality that you will receive and cheap refers to the cost or resources throughout the project. I am going to review all three points of the triangle, as well as the importance of quality. In addition, I......

...3G And 4G Advancements in the mobile communication industry are changing the way we live our daily lives. “Researchers and technology leaders envision a future immersed in wireless communication that will play a pivotal role in realizing this Network Utopia — a world of smart, intercommunicating everything.”[1][2] 3G, 4G and beyond networks are already taking the first steps toward achieving this goal. 3G systems allow the use of speech and data services together and have higher data rates compared to 1G and 2G, with speeds of up to 14Mbit/s. 4G systems will be an all IP based solution seeing data rates of up to 100Mbit/s – 1Gbit/s for mobility. Even though at the moment 4G systems have not been implemented, the race to develop a 5G mobile communication system has begun. 5G systems will have flatter architecture than 4G and be completely wireless with no limitations. The paper will focus on how the limitations of 1G and 2G networks has led to the development of 3G and 4G, and looks at existing and proposed mobile systems architectures. The review will show that wireless technology is moving towards allowing a user to communicate with anyone, at anytime anywhere. High Data Transfer Rates: Stationary devices will have data rates of up to 2.05Mbits/s, for devices moving slowly data rates of 384Kbits/s will be available and for devices that are being moved fast will have data transfer rates of 128 Kbits/s.Broader bandwidth: Allow the use of speech and data services......

Microsoft Project will be used as a tool to organize and manage the complete project, and it will include budget and schedule. We also must remember that the main design centers are in San Francisco, Detroit, Paris, Tokyo, and Sao Paulo, with Corporate Headquarters lodged in San Francisco. The remaining offices are used as sales offices. Consider the company to operate on a 24 hours a day and 7 days a week basis, because it is global. It has been said, that with the advent of globalization, WAN has become a major artery for communication between remote offices and customers in any corner of the globe. Additionally, with data center consolidation, applications are moving to centralized data centers and clouds. We can also take advantage of virtualization within the centralized data center. WAN plays an even more critical role, because ABC survival is dependent on the availability and performance of the network. In the past reliable connectively was predicated upon performance with the utilization of private WAN using Multiprotocol Label Switching (MPLS) or leased line service. This norm is very expensive and the least cost effective for ABC. It was basically impossible to have WAN transport in order to support growing bandwidth requirements for remote-site connectivity.

...Local are networks (LAN) is a computer network covering a small geographic area, like a home, office, school, or group of buildings. Has a High speed (1000 mbps) Tends to use certain connectivity technologies, primarily Ethernet and Token Ring. LANs tend to have fewer problems associated with them, as there are smaller numbers of systems to deal with. Wide area network (WAN) is a computer network that covers a broad area. It does have slower speeds of about 150 mbps. WANs tend to use technologies like MPLS, ATM, Frame Relay and X.25 for connectivity over longer distances Differences between (LAN) & (WAN) (LAN) is typically owned and managed by a single company or organization. LAN also experiences fewer data transmission errors and overall fewer problems as a whole as opposed to WAN. WAN has a high cost maintenance and lower bandwidth. In conclusion the major differences are going to be cost, efficiency and coverage Describe common physical topologies and a logical topology : Physical topology refers to how the network is wired it can be either a ring topology where all the hosts are connected together or a bus topology where there is a network medium and each host connects to that medium by wire. A logical topology in the other hand governs how the network is going to work. For example all the hosts in the network are connected through a central connecting point that’s the physical topology however the way the protocols and hardware are designed to......
