What is UHF CB Two Way Radio?

UHF CB is a class-licensed citizen’s band radio service authorised by the governments of Australia, New Zealand, Vanuatu, and Malaysia in the UHF 477 MHz band. UHF CB provides 77 channels, including 32 channels (16 output, 16 input) allocated to repeater stations. It is similar in concept to 27 MHz CB Radio in the United States, Australia, and New Zealand.

Class licensing means that users do not have to apply for a licence or pay a licence fee however they must comply with the regulations of the class licence.

User equipment designs are similar to commercial land mobile two-way radio except the maximum legal output power is 5 Watts. External antennas are permitted and commercially manufactured antennas have gains as high as 12 dB. Handheld transceivers (handy talkies) are permitted and have transmit power from 500 mW to 5 W (full legal power) and are relatively cheap compared to full-sized transceivers. Operation in the band is restricted to modes F3E and G3E (FM or PM of analogue voice telephony) except for channels 22 and 23, which are data modes only.

Channel 5 and 35 are the designated emergency channels in Australia, Vanuatu and Malaysia, and are not to be used except in an emergency. Making an emergency call involves switching the radio to Channel 5 with duplex on, and trying again with duplex off if there’s no response. In New Zealand channels 5 and 35 are not emergency channels, they are available for general use in duplex (repeater) mode. In New Zealand, if you use UHF PRS for emergency, you rely on someone listening on the same channel. Scan all channels for activity before requesting assistance.

Channel 9 is the designated emergency channel in Malaysia.

Channel 11 is the ‘call channel’ and is only to be used for initiating calls with another person, who should quickly organise another vacant channel to continue their discussion.

Channel 22 and 23 are only to be used for telemetry and telecommand. Packet data and voice transmission are not allowed.

Channel 61, 62 and 63 are reserved for future allocation and transmission on these channels is not allowed.

When Buying a Walkie Talkie, is it Better to Choose a Long Antenna or a Short One?

We all know that the antenna of the walkie talkie is proportional to the transmission and reception of the walkie talkie. The antenna is a device that transmits electromagnetic waves into the air. We usually use walkie talkie, in order to send more energy (or power) to the air, so that when the other party receives the signal, there is enough energy to restore the content of the information. The antenna is an important part of the transmitting part. Today, Xiaobian will talk with you about the choice of long antenna or short antenna when buying walkie talkie?


In fact, the antenna of the walkie talkie is not distinguished by the length of the antenna, but by the frequency band. Although the antenna is usually selected with long or short antennas, the final selection is based on the frequency written by the walkie talkie. You can look at the bottom of the antenna. Generally, there will be remarks at the bottom of the antenna to explain the applicable frequency range of the antenna. If the frequency written by the walkie talkie is within this range, the antenna is applicable. Of course, each interphone manufacturer produces each interphone with a central frequency.

5G New Construction Accelerates The Development of Private Network Communications, The Public Network Can Open Up New Market Space?

In our daily life, we often see the police on duty and subway dispatchers wearing an intercom at work. Whenever something happens, press the switch to talk to colleagues in the headquarters or elsewhere. The communication network between walkie-talkies is called “private network communication”, which is generally used in specific industries or enterprises. Its users are mainly industrial users who have high requirements for network reliability and security, including governments, railways, subways, and airports. , Ports, power, petrochemical, mining, water conservancy, etc.

Although ordinary users seldom contact, whether it is the smooth holding of large-scale events, international events, or timely response to earthquakes, fires, and terrorist attacks, they cannot do without private network communication. It can even rescue lives in critical moments. And the characteristics of reliable performance, low cost, and customization make private networks have irreplaceable advantages in industry applications

However, it is worth noting that the evolution of private network technology is still relatively slow compared to the public network, and the arrival of the 5G era may change this form. Some experts said that in the 5G era, because 5G takes into account the needs of vertical industries from the overall system design, the situation of “private public network” will become more obvious. The 5G public network built by telecom operators can serve industry users very well through special technology; private network service providers can make full use of public network broadband wireless communication network resources to build necessary private network communication services on the public network And broadband-based services. From this perspective, the integration of public and private networks will better meet the needs of industry users and promote the industry to create a huge market

Relevant data show that the global private network market is about 10 billion to 20 billion US dollars, but the opportunity of the public network private market will expand more than 10 times. Industry users will increase their investment in the construction of their dedicated communication network and supporting terminals, software, services, etc., to ensure the operation of their dedicated network communication system. Therefore, the upgrade and transformation of existing private network communication networks based on 5G technology on a global scale will bring huge market space

Specifically, the traditional private network solves the problem of voice coverage, and focuses on converging communications under the background of “new infrastructure”. Public and private networks are interconnected, and information and video are interconnected. Intelligent public safety and emergency communications will be Bring a lot of business opportunities. At the same time, the “new infrastructure” pays more attention to to B and to C customers, and supports more scenarios and applications with the support of new technologies such as 5G, cloud computing, and artificial intelligence. In addition, “new infrastructure” is an important driving force for economic growth, and capital support such as special bonds and special funds will also bring great increases.

What is Ham Radio?

Amateur Radio (ham radio) is a popular hobby and service that brings people, electronics and communication together. People use ham radio to talk across town, around the world, or even into space, all without the Internet or cell phones. It’s fun, social, educational, and can be a lifeline during times of need.

You can set up a ham radio station anywhere! In a field

at a club station

Although Amateur Radio operators get involved for many reasons, they all have in common a basic knowledge of radio technology and operating principles, and pass an examination for the FCC license to operate on radio frequencies known as the “Amateur Bands.” These bands are radio frequencies allocated by the Federal Communications Commission (FCC) for use by ham radio operators.

2 Practical Reasons to Use Two-Way Radios

1. Safety

Safety is the No. 1 concern for any professional cleaner or custodial firm. According to the U.S. Bureau of Labor Statistics, in 2015 custodians and cleaners suffered an average of 50,000 injuries that required them to take days off from work. Even more staggering, the industry is in the top 20 most hazardous occupations, along with logging, professional fishing, and roofing.

Cleaning injuries can range from accidental exposure to hazardous chemicals to slips, trips, and falls. Two-way radios are valuable tools for anyone who works in an isolated or remote area as custodians often do. Unlike cell phones, which may not be able to receive or send a signal and can be hard to operate in the midst of an emergency, two-way radios can provide immediate and reliable communication.

For example, most professional-grade, two-way radios have a programmable emergency alert button located on the top of the unit. During an emergency, workers can push the button to immediately send out an alert to either the entire network or a specific user. The signal will reveal which radio sent the alert. This feature allows two-way radio users to instantly communicate with each other while maintaining distance between them, which is especially valuable in this age of the highly contagious coronavirus.

2. Efficiency
A two-way radio is a useful tool for maximizing efficiency in any facility setting. Consider a cleaning crew dispatched to a large office building with multiple floors. One worker may encounter a problem on the seventh floor that requires a second opinion or supervisory instruction. With a professional-grade, two-way radio, the worker can instantly notify another team member or supervisor to receive the additional support needed to get the job done. Not having to leave a location to secure help saves the worker time and saves the company money.
