How Does a Fax Machine Differ From a Cell Phone?

How Does a Fax Machine Differ From a Cell Phone?

Fax machines

Fax machines use tones to communicate with each other and establish a connection. Tones here refer to a specific frequency that fax machines use while transmitting data.

The most important tone for a fax machine is the recognition tone. Its purpose is to identify a fax number that belongs to a fax machine on the line. After establishing the connection, the fax machine will send a series of handshaking tones to negotiate data transfer.

These tones synchronize the two machines and ensure that the data is received correctly. Analog lines, which are used in landline telephones, can carry these tones without distortion. This makes them the ideal choice for traditional faxing.

Cell phones

On the other hand, mobile phones use digital signals to communicate. These digital signals are made up of 1s and 0s, which are then translated into data humans can understand.

The use of digital signals is the main reason why you can’t just connect a fax machine to a cell phone and expect it to work. The two devices use different methods to send and receive data, so they are inherently incompatible.

However, it is still possible to connect fax machines to your smartphones. In some cases, you may need special hardware or software to do this. Let’s look at the methods you can use.

How to Connect a Fax Machine to a Cell Phone

Wireless phone jack system

A wireless phone jack is a system that uses two units — a transmitter and a receiver. This system uses a base station that can connect to corded and cordless phones, answering machines, fax machines, and computer modems. You can purchase a wireless phone jack system in most electronics stores.

Fax over Internet Protocol (FoIP) providers

FoIP is a way of sending a fax using an Internet connection instead of a phone line. FoIP providers typically offer both cloud-based and on-premises solutions. To use FoIP, you must purchase a special adapter that connects your fax machine to a digital server. This is where you can save your fax documents on cloud storage services for ease of access and retrieval.

While FoIP offers many advantages over traditional fax lines, the cost of adapters and monthly fees for service providers deter many users.

VoIP fax adapter

A VoIP fax adapter is a device that turns the signal from a traditional fax machine into packets of data that are transmitted through the internet.

HTTPS is one such special fax adapter. Since faxes need to be encrypted, it uses Secure Sockets Layer (SSL). The fax must go through a server, so fax adapters can only work with others. You need to have a subscription with a FoIP company that supports the specific fax adapter.

FoIP providers primarily provide a gateway service while offering the HTTPS fax adapter as an add-on service. However, these fax adapters and FoIP providers do not come cheap.

Can I Use My Fax Machine Without a Landline?

No, you cannot use a fax machine without a landline. Fax machines are technically telephone devices that use the landline network to send information.

What’s the workaround? Use a mobile fax app, which makes it possible to send and receive a fax using your mobile phone without a landline or even a fax machine.
