Landline telephony

Landline telephony

Landline telephony entails a phone that is connected through a plug to the landline phone network that is built on phone towers and copper wires. Even wireless phones can be included in landline telephony in this sense. Mobile networks and IP telephony are however systems that are built on completely different technologies.

Landline telephony has existed in Sweden since the 1870s and the development of the landline phone network has in large part been a public undertaking. Almost all buildings in the country have been able to connect to the so called copper network. Now we’re in the middle of a paradigm shift.

The landline phone network is being terminated in many parts of the country and will be replaces by the mobile alternative. There are both pros and cons with this and we’ll take a closer look at it in this text.

  • Landline telephony is often called the copper network due to the copper wires it’s built on
  • The system has existed for more than 100 years
  • A benefit with landline telephony is that the phone works during power failures
  • The landline network will be replaced by new technology
  • The new system for telephony has higher capacity
  • Calls through IP telephony and mobile networks will be strong
  • The landline network is also used for ADSI internet

Why terminate the copper network?

Landline telephony is being replaced with modern technique. Copper networks need maintenance and aren’t considered profitable when the customer base is decreasing due to new and better alternatives. The lifeline for the copper network has been its’ use for DSL and ADSL, which are techniques for data transfer in different frequencies than those used for voice.

With almost everyone owning a mobile phone today, the need for landline telephony is steadily decreasing. Parts of the copper network lack the capacity that many require and its’ therefore seen as a less attractive alternative than fiber and mobile telephony.

Telia is today a private company and has, in another way than when it was public, adjusted to what most cost efficient alternatives. Mobile solutions are cheaper for carriers. Another argument for the termination is that it’s far more sensitive to accidents.

Critique against the termination

In some parts where the termination has begun, there’s still no better alternatives. There are many households that get stuck in the gap between two different techniques are suffer because of it.

The landline phone networks had a current supply that was independent of the individual households. This means that it was possible to call even if power failures were to occur. Now it requires charged extra batteries. For those that have yet to adapt to the new mobile technology, this is seen as an issue.

When you’d make emergency calls with a landline phone the carrier could directly see your location, which isn’t possible with a mobile phone. Some feel worries about the new telephony due to radiation exposure. New developments and changes always bring new critiques.
