Can I get unlimited mobile broadband?

Broadband applications such as Internet consultation, video on demand (VoD), payg broadband, compared to Ethernet, SDH technology is more complex; and voice over IP (VoIP) are real incentives for the deployment of OEoF to businesses. This model is called Fiber To The Building.

Synchronous Digital Hierarchy (SDH)

SDH or Synchronous Digital Hierarchy is a high-speed transmission technology, based on a “ring”. This type of structure provides a different geographical route, ensuring a backup path in the event that the primary path becomes unavailable. The transmission speed is organized in multiples of 155 Megabit / s and can reach 2.5 Gbps.
Among the characteristics of this technology, we can note that:

  • SDH equipment is not available to everyone;
  • the granularity of the transmission rates is only suitable for telecommunications operators.

The metropolitan network

A Metropolitan Area Network (MAN) is a network that covers approximately an urban area. The MAN is an intermediary between the WAN  (Wide Area Network) and the LAN (Local Area Network).
This new model, already widespread outside our borders, consists of the contractual provision of a passive cabled optical fiber network infrastructure by an organization (private or public). An intermediary is responsible for maintaining, administering, and making the infrastructure profitable while stimulating the market for both end consumers and service providers.

Some examples

Many experiments are now underway:

  • Sweden: in 2000, B2 Bredband AB started a metropolitan network (Ethernet over optical fiber) whose main target is collective residential housing. By simply connecting their computer to a network wall outlet available in their home, the customer will be able to access Internet services with a symmetrical speed of 10 Mbit / s. Through partnerships with large Swedish real estate organizations, home broadband no contract, B2 Bredband AB provides more than 80,000 households with services such as IP / TV, video, or games on demand.
  • Italy: e.Biscom’s FastWeb service interconnects over 300,000 homes and 50,000 businesses through a direct fiber-optic connection. By 2010, the operator plans to interconnect all Italian cities of more than 45,000 inhabitants, thus covering more than 1 million households. FastWeb has fully embraced the concept of “triple play” by offering users asymmetrical 10 Mbit / s Internet service, as well as television and video on demand, telephony, and videoconferencing services. Companies can opt for speeds of 1 or even several Gbit / s, thus having access to services such as disaster Recovery or VPNs. Fastweb is based on the metro Ethernet model;
  • Ireland: the government has launched, in partnership with local and regional authorities, the creation of 25 metropolitan networks in towns and cities where no telecom infrastructure is available. These new fiber-optic networks will be managed by a single organization and access to fiber will be open. Here again, the OEoF model was chosen.
  • Netherlands: many cities have initiated projects to make fiber optic available. The city of Amsterdam plans to connect all private homes and businesses to the fiber-optic network, which represents 450,000 connections. The authorities have also opted for the model of owning the passive network (by Citynet Amsterdam) and delegating the active layer of the network to a third party in order to obtain an “open” network allowing citizens and businesses maximum freedom. choice of services;
  • United States: Verizon is preparing a very high-speed Internet service offering using optical fiber to reach its customers. They will use the FTTP (Fiber To The Premises) model to reach at least half of its residential customers in a few years. The technology will make it possible to offer customers a broadband connection with a data rate of 30 Mbit / s. Verizon has about 40 million customers today;
  • Japan: at the end of March 2004, nearly 1.15 million Japanese were connected to the Internet through a fiber-optic connection with a speed of 100Mbit / s. Forecasts indicate that by 2006 this figure will rise to more than 7.73 million connections, virgin no contract broadband, thus dethroning ADSL  or cable connections.

What 4G frequencies are used by operators to deploy very high-speed mobile?

Since November 2012, mobile telephone operators have started rolling out 4G,  no contract fibre broadband , and are already offering new offers. But what is 4G? How does it develop? What will it change in our daily life? 4G ( Fourth generation) 4G (or Fourth generation) is a new technological advance in mobile telephony, which succeeds 2G and 3G. The second-generation (2G) corresponds to the arrival of the new communication standard for mobile phones: GSM (Global System for Mobile Communication). It improves international voice communications and allows, thanks to the digital circulation of data, the sending of SMS. The Third Generation (3G) represented by the UMTS standard offers fast speeds ranging from 2 to 42 Mb / s and thus initiates access to the Internet from a mobile, as well as video viewing and video telephony. 4G, under the LTE-Advanced standard, is today a real revolution since it offers a multiplication of speeds thanks to two phenomena...

Can I get temporary broadband?

What is the difference between ADSL, VDSL, and fiber? The ADSL and the VDSL are two technologies that borrow the traditional telephone line to pass the Internet data, no contract broadband , the television stream, and the telephone (VoIP). The first allows speeds of up to 25 megabits / s and the second up to 100 megabits / s. Depending on the equipment installed by the ISP at your telephone exchange (or distributor), you will benefit from one or the other. Please note: these data are only theoretical. The further away you live from the telephone exchange, the lower the actual speed will be. If your building has fiber, opt for optical fiber which offers much better performance and much higher speeds. Be careful, however: with some operators, How do I know the speed at which I can really claim? You should check with each ISP, including indicating your phone number on their website. Do not hesitate to consult our comparator of Internet service ...
