Telecommunication networks

A telecommunications network is a set of devices, transmission channels and procedures by which two remote user terminals connected to the network (e.g. telephones, computers, cell phones, fax machines, webcams, etc.) can exchange information.

Access network

The access network (so-called last mile) is the network that connects the business site to the first communications station in the area.
It uses various transmission media (copper, fiber or radio) based on available technologies and the Customer’s bandwidth needs.
The most widespread access technologies are those that use copper and fiber optics or a combination thereof.
The distance of the local business site from the street cabinet or the local communications station affects the performance of the service supplied on copper and too much distance will eventually make the service impractical.

Asymmetric access

Implemented on shared or dedicated (naked) lines, they are designed for residential or business use where the primary use is browsing and streaming content on the internet.

Symmetric access

Implemented exclusively on dedicated lines, they are designed for professional use where the concurrent use of services (voice, VPN, cloud services, desktop sharing, etc.) is required. This means low latency, higher guaranteed minimum bandwidth and faster recovery times in the event of line failure.

Transport network

The transport network is the network that connects the national and international access networks together.
It mainly uses high-capacity fiber transmission media.
Operators (like Welcome Italia) and Service Providers are the principal network nodes that make up the so-called Big Internet.

Network management

The technological development of the telecommunications networks has allowed the Operators the opportunity to adopt network resource management policies (known as overbooking) that can transfer important economies of scale to end-Customers.
These economies, based on the intensity of simultaneous use of resources, however, require the Operator to employ higher network monitoring and control capacity than in the past, to avoid undesirable degradation of performance due to saturation (i.e. bottlenecks).
In practice, each Operator wishing to pursue demanding quality objectives must be able to measure and constantly adapt their services to the habits and needs of their Customers.

The difference lies in control

The continuous development and the increasing availability of services and applications delivered over the network have made the telecomms infrastructure a strategic asset for the growth of any business.

At Welcome Italia, we work every day to ensure the highest standards of service and so we have created:

  • a high-capacity transport network, with redundancy system, dedicated to our Vianova Customers, to allow secure connections with our two Data Centers
  • a sophisticated measurement and control system that can track real-time voice and data traffic broken down for each area, so as to scale the transport network transmission capacity to levels that always exceed the maximum peak usage of our Customers
  • an area of ​​our website reserved for our Customers where, with a view to maintaining a relationship of maximum transparency, we display a chart of actual bandwidth consumption, selectable for each site, that automatically updates every minute
  • a Line TestWI service, unique in its kind, able to detect not only the access speed of the individual computer from which the test is executed (as everyone does), but to simultaneously measure the sum of the access speeds of all devices (computers, servers, WiFi terminals, etc.) connected to the Customer’s LAN

Access technologies

  • FTTC (Fiber To The Cabinet) – The fiber optic connection comes to an external cabinet very close to the user’s premises (typically within 700 meters), to then reach the end-Customer site via a copper twisted pair with VDSL or VDSL2 technology
  • FTTH (Fiber To The Home) – The fiber optic connection reaches the user’s particular site directly
  • xDSL – The individual user’s site is reached by one or more copper twisted pair cables using ADSL (asymmetric) or SHDSL (symmetric) connected directly to a DSLAM installed in the local telephone exchange
  • WLL (Wireless Local Loop) – The individual user site is reached by a shared-bandwidth point-to-multipoint radio link or dedicated-bandwidth point-to-point with Hiperlan or WiMax technologies
