What is a cordless phone?

A cordless phone (portable phone) is one in which the handset connects to the base unit via a radio link rather than a cord. That makes the handset portable within the range of the radio waves. In the setup, the base station connects to a telephone line. The base station also charges the handset, even as it transmits telephone signals.

What is a digital cordless phone?

A digital cordless phone is one that utilizes the Digital Enhanced Cordless Technology (DECT). Like traditional cordless phones, it can connect to the base wirelessly. As such, you don’t need to plug a telephone line directly into the phone. Instead, the telephone line connects to the base unit.

What are the advantages and disadvantages of digital cordless phones?

  • The first advantage of digital cordless (or DECT) phones provides a wide range of 50 to 300 meters. That’s much better than would have been possible with a landline.
  • Digital cordless phones have bases that support at most six handsets. Therefore, you can place a handset in each room for more convenience. You may also use them in the office.
  • If you use a repeater, you can increase or double the range of the phone. That makes it possible for the signal to penetrate thicker walls.
  • Most DECT phones allow you to connect and use Bluetooth headsets to make and receive calls. It works well for people whose work involves receiving a lot of calls.
  • DECT phones come with advanced features such as call blocking, caller ID, and crystal-clear speakerphones. It all depends on the model you want to buy.
  • DECT phones have one major drawback, which is their constant need for power. That means the loss of electricity will cut off your communication.

How do cordless phones work?

A cordless phone, whether analog or digital, has two components – the base unit and the handset. The bane unit has a port through which you connect it to a telephone line. Also, it has a power inlet that connects directly to mains electricity. The radio part of the phone sends and receives signals to and from the handset.

The handset, on the other hand, has a speaker, microphone, keypad, ringer, and radio. It also has an LED or LCD and a rechargeable battery. The speaker is the component that gives you the sound you hear. While the microphone picks the voice and converts into electrical signals, the keypad is for dialing. The buzzer ringer alerts you when someone calls, and the radio sends & receives signals. Regardless of whether it is an LED or LCD, the display shows the caller ID and telephone numbers. Lastly, the rechargeable battery powers the phone.

Remember, a cordless phone works when you plug in the base unit, and the handset has a charged battery. When a call comes in, the base unit sends a signal to the handset. As a result, the ringer sounds prompting you to pick the call. When you answer a phone call, the conversation will move back and forth between the base unit and speakerphone. That’s also true when you call another telephone number.

How to set up a cordless phone?

Setting up a cordless phone takes the same necessary steps, regardless of the brand name. Start by selecting a spot where you can connect the base unit to electricity and a telephone line. Plugin the base unit, connect the telephone line, and that’s it. You are ready to start making and receiving calls.

If your system requires you to charge the battery, then make sure you do that. If you don’t, your phone system may not work as expected. You may want to configure details such as the date and time, answering machine messages, and so on. Also important is changing the call blocking features.

Can I make mobile calls on a cordless handset?

Yes. Most cordless phones allow for wireless connection to mobile phones. Some use an essential Bluetooth connection, allowing you to make and receive mobile calls via your handset. A good example is the Panasonic Link2Cell Cordless Phone, which offers connectivity with mobile phones. Still, other models make it possible to transfer contacts between the two phone systems.

The more advanced cordless phones connect to smartphones via your home’s Wi-Fi network. That allows you to receive calls on your smartphone and read messages remotely. With that, you don’t need to be within the phone’s network range to make or answer calls. The best example is the VTech IS8151-5 Super Long Range 5 Handset DECT 6.0 Cordless Phone with Siri and Google Assistant.


The popularity of cordless phones has been increasing over the last few years. That’s mainly because they work for the elderly, hard of hearing individuals, and so on. Even if you have a mobile phone, you can still install a cordless phone system in your home. The most advanced devices work together with virtual assistants to enhance your connectivity.
