"Since January 1, 2011, the model approval for analog walkie-talkie devices in the 150MHz and 400MHz frequency bands will be suspended. Analog walkie-talkie devices that have obtained model approval certificates will no longer be subject to extension procedures after the model approval certificates expire; until 2016 China will completely ban the production and sales of analog walkie-talkies, and analog walkie-talkies will be completely replaced by digital dedicated walkie-talkies and withdraw from the market." This is the determination of China’s gradual transition to digitalization of the production, sales and use of dedicated analog walkie-talkies in the 150MHz and 400MHz frequency band Now that several years have passed since the timetable and roadmap, the overall evolution has made significant progress. Today we will talk about the difference between digital and analog. What are their advantages and disadvantages?
The analog walkie-talkie is a traditional radio type, while the digital walkie-talkie is the latest radio technology, and each has its own unique differences. The analog two-way walkie-talkie was first introduced into the business world around 1933, but by this time the US military had been using it for 20 years. Initially, the use of analog walkie-talkies was limited to a few people, but it later developed into a more popular way of communication. Radio is a reliable means of communication. Commercial, military, industrial and personal use radio every day. So we need to figure out new ways to keep radio waves open to everyone.
Analog technology has existed for a long time, and during this time the innovation of this technology has reached its peak. When there is nothing to add to the analog, the digital radio system was invented to meet today's society’s need for rich functionality.
The signal types of analog and digital walkie-talkies are different, but the two types of equipment also have many other differences, such as sound quality and price. Because of the invention of digital radio, wireless communication has grown and developed. Improvements to digital walkie-talkies include:
1. Larger call range 2. Better sound quality 3. Increased reliable coverage 4. Advanced software availability
These are just some of the advantages of digital platforms. Analog walkie-talkie also has its own advantages. Since its birth, analog walkie-talkies have been the main form of two-way wireless communication. Today, many radio systems still operate in analog mode. With the development of digital technology, more and more professionals are turning from analog to digital.
Traditional analog two-way radios usually come with standard options, such as push-to-talk, scanning, limited encryption options and simple one-to-one or group conversations. Historically, due to innovative gameplay, analog radios were able to perform many additional tasks.
The functions of digital walkie-talkies are different. Some walkie-talkies have the same functions as analog walkie-talkies, while some digital walkie-talkies have additional functions. Depending on the manufacturer and the type of walkie-talkie equipment you buy or lease, the included features will vary greatly. All digital walkie-talkies can almost guarantee 30-50% longer battery life than analog walkie-talkies. This is because digital radio transmitters do not operate around the clock.
The sound quality of a standard analog walkie-talkie will decrease as you use it to continuously approach or exceed its allowable maximum range. At this time, all you hear is white noise. For digital walkie-talkies, the sound quality you hear will remain the same regardless of the maximum distance.
Today's analog walkie-talkies use frequency modulation (FM), which can generate a constant sound signal wave. This is a fairly simple system installation, which makes analog radios cheaper. Despite the low price, the penetration rate of analog walkie-talkies is still declining.
The number 1 or 0 represents a digital signal. Depending on the number, the voltage value is also different. The digital signal includes an algorithm that can identify conversations and background noise; this means clearer communication. Wireless digital signals are considered as reliable as wired digital signals.
Advantages of analog radio
Since analog walkie-talkies have been around for a long time and have a wide range of applications, there are many accessories and additional components to choose from. The analog system is easy to use and is generally well known to the public. These systems efficiently use bandwidth.
Disadvantages of analog radio
In most cases, only one two-way conversation can be conducted using the same channel in a given time. The receiver and transmitter are made to adapt to specific transmissions. Equipment can be upgraded, but technology cannot be upgraded. Commercial application software cannot be used for simulation.
Advantages of digital walkie-talkie
One channel can have more conversations. Device ID, enhanced text messages and status buttons can all be embedded in digital broadcast channels. Your bandwidth consumption is reduced by digital walkie-talkies. Existing infrastructure and antenna systems can be used to transmit digital signals. Since advanced algorithms can detect the difference between conversation and background noise, background noise is greatly reduced. Many new software applications are always available. The digital platform enables you to use digital and analog radio at the same time.
Disadvantages of digital walkie-talkies
Users who use it for the first time need more time to learn how to use it. Digital signals cannot tolerate radio frequency (RF) signals, so if there is too much radio frequency noise, the signal will drop erroneously. Because it is a new technology, the price of digital walkie-talkies is relatively expensive.
