We live in a hyper-connected world where communication is the key to business success. From hand-written letters to emails, from phone calls to video conferencing and from walkie-talkies to cellular push-to-talk apps, communication has greatly evolved to facilitate instant global connectivity. As more and more businesses rely on mobile devices to keep their field workforce connected, push-to-talk apps are gaining popularity.
If you have worked in the field, or if your business has a field workforce then you must already be familiar with the term push-to-talk. It is a half-duplex communication mode that is used by devices such as walkie-talkies and land mobile radios. But what does half-duplex mean? If walkie-talkies work on a half-duplex mode of communication, then does a full duplex exist too? Let’s understand the various modes of communication.
What is Simplex Communication?
Simplex communication is a uni-directional mode of communication in which two devices are connected, but only the sender can transmit messages and the receiving end can simply listen. This mode of communication creates a one-way channel for information transmission.
Advantages of simplex communication:
- It is a one-way transmission and utilizes the full capacity of the communication medium.
- Enables greater data transmission at a time since the entire bandwidth is utilized.
Disadvantages of simplex communication:
- Presents only unidirectional communication.
- No inter-communication between devices.
- Cannot be widely used for modern-day communication.
What is Half Duplex Communication?
Half-duplex communication is when two devices are connected, and both the sender and the receiver can communicate, but not simultaneously. It is a bi-directional mode of communication in which the sender and receiver can transmit voice messages one at a time.
Advantages of half-duplex communication:
- It is easy to implement.
- No hardware complications.
- Offers time-saving communication.
- Can be leveraged over cellular and radio networks.
Disadvantages of half-duplex communication:
- Lower speed and performance in comparison to the full-duplex method.
What is Full Duplex Communication?
Full-duplex communication is a bi-directional mode of communication in which both the sender and the receiver can communicate simultaneously. Unlike half-duplex communication, full duplex communication can establish a continuous two-way connection.
Advantages of full-duplex communication:
- High-performance in comparison to half-duplex communication.
- Faster speed of transmitting and receiving the data.
- It doubles the utilization of the bandwidth.
- Best suited for modern-day office communication.
Disadvantages of full-duplex communication:
- Not all network equipment supports a full-duplex system.
- Connectivity may be time-consuming in comparison to half-duplex communication.
- Sometimes causes difficulty for the administrators to diagnose the issue in the network due to instability.
Difference Between Simplex, Half Duplex, and Full Duplex Modes of Transmission:
Parameter | Simplex Communication | Half-Duplex Communication | Full-Duplex Communication |
|---|---|---|---|
| Direction of communication | It is one-way communication in which only the sender transmits the message and the receiving end hears the message. | It is two-way communication in which both the sender and the receiver can transmit messages, but one at a time. | It is two-way communication in which both the sender and the receiver can transmit messages simultaneously. |
| Sender & Receiver | The sender can only send the data but not receive it. | Both sender and receiver can send and receive the data. | Both sender and receiver can send and receive the data. |
| Bandwidth | Simplex communication makes full use of a single bandwidth. | Half-duplex communication makes lesser use of a single bandwidth in comparison to full-duplex mode. | Full-duplex communication doubles the use of transmission bandwidth. |
| Performance | Yields a lower performance compared to half and full-duplex modes. | Yields a lower performance when compared to the full-duplex mode of communication | Yields the maximum performance as it makes use of double the bandwidth. |
| Examples | Televisions, radios, monitors, keyboards and microphones connected to speakers. | Walkie-talkies, two-way radios, land mobile radios. | Cellphones, telephone lines. |
| Industry Use-Cases | Emergency services, security services, healthcare, education, retail. | Construction, Logistics, Retail, Warehousing, Mining, Security services, Emergency services. | All industries. |
Why Is Half-Duplex Communication Ideal for a Field Workforce?
While most of the corporate world enjoys the benefits of full-duplex communication, some industries with a field workforce find cellular phone calls cumbersome and futile. Industries such as construction, warehousing, logistics and transportation, etc. have a field workforce that operates from remote, high-risk environments where speedy communication is critical. Two-way radios such as walkie-talkies leverage half-duplex communication to offer instant push-button connectivity.
The field workforce functions in hazardous locations and operates heavy equipment. Here are some reasons why half-duplex communication outstands full-duplex communication for field employees:
- Hands-free communication
- Quick press-button connectivity
- No fuss of dialing numbers and typing long messages
- Straightforward and no-frills communication
