The Motorola system officially released the new MTP3000 series TETRA handheld walkie-talkie products, which has further improved safety and reliability than the original products, and adopted a new standard in audio effects.

The MTP3000 series is equipped with the most sensitive receiver on the market (the sensitivity of all existing TETRA walkie-talkies has been enhanced to a -2db), reaching a network 14% higher than the specifications of the European Telecommunications Standards Institute (ETSI). Coverage and expansion of network coverage by 30%. Adhering to the philosophy of “excellent audio quality”, the MTP3000 has optimized volume and speech intelligibility, combined with a state-of-the-art PA system to ensure clear, smooth voice calls even in extremely noisy environments.

In terms of airframe configuration, the MTP3000 series walkie-talkie has greater sensitivity and 1.8W output power, achieving optimal network coverage, increasing coverage within the building and enhancing customer safety. At the same time, they are equipped with two control knobs for volume adjustment and talk group selection. When the user wears the product on the body, there is no need to worry that the walkie-talkie is not in the line of sight and affect the operation. This configuration and experience similar to that of the simulator can also help users make an easy transition from analog to digital. In addition, the MTP3000 Series features a new, fast and rugged (IP65 certified) wing connector that allows users to load and unload accessories in less than two seconds. The MTP3000 Series is also fully supported by Motorola’s integrated terminal management system, ensuring that the organization can effectively master the overall team situation of all terminals.

The new MTP3000 has a number of exquisite ergonomic designs, such as slight protrusions of the buttons, and a reasonable spacing for easy and accurate operator input and optimum hand feel during use. At the same time, the bottom interface of the MTP3000 has been specially designed to have a self-cleaning function and is easy to clean.

With a number of new features to meet operational needs, the MTP3000 Series offers more choices for users in the public security, fire, armed police, urban rail transit, and airport, port, and energy industries to meet their diverse product needs.

Jiang Hao, Chairman and President of Motorola Systems (China) Co., Ltd., government and corporate customers hope to obtain TETRA walkie-talkies with higher security, ease of use and durability to assist people who often use walkie-talkies in harsh environments. Ability to focus on mission-critical execution. The MTP3000 Series offers a comprehensive upgrade in performance while maximizing the ability of users to manage different devices and accessories. It is believed that with its excellent audio, reliable security and excellent functions, the MTP3000 series walkie-talkie can further meet the communication needs of customers and help them to achieve the best at every critical moment.

It is reported that the MTP3000 series currently has three models MTP3100, MTP3150 and MTP3250, all of which are available now, offering a full range of products in both 350MHz and 800MHz.

For different users and different industries, radios can generally be divided into professional radios and amateur radios.

Civil walkie-talkie

   On different occasions, these two walkie-talkies play their respective functions, so where are the differences?

Professional walkie talkie

   Most users of professional radios are used in the professional business of group teams. Therefore, the professional radio walkie-talkie is characterized by simple and practical functions. In the design, there are a variety of communication interfaces for users to make secondary development. The frequency report setting is mostly through computer programming, the user can not change the frequency, the panel displays only the number of channels, does not directly display the frequency point, the frequency has good confidentiality, the frequency stability is also high, and the frequency is not easy to run.

  In long-term work, its stability and reliability are high, and the operating temperature range is wide, generally ranging from -30 degrees to +60 degrees. The working frequency of the professional machine is a part of V high section (148-174MHZ) and V low section (136-160MHZ) in the VHF section. The other part is the whole section (136-174MHZ). However, in the UHF band, most of the U-segment (450-470MHZ) and U-segment (400-430MHZ), very few U-segment (400-470MHZ). The performance, reliability and stability of professional machines are higher than those of amateur machines. The price is naturally higher than that of amateur machines, and some are even higher.

Amateur radio

  A radio walkie-talkie designed and manufactured to meet the needs of radio enthusiasts. Such walkie-talkies can also be called “playing machines”, and fans who play walkie-talkies are called “HAM” or “ham”. Due to the limited frequency range of the radio, the environmental conditions and usage requirements of the radio are different from those of professional walkie-talkies. The main feature of the amateur machine is that it has a small size, complete functions, and frequency scanning. The frequency can be directly set on the panel, and the frequency point is displayed on the panel. Its technical indicators and equipment for this amateur personal radio service, each country has opened a dedicated frequency band allocated to amateur radio sports enthusiasts. The frequency bands opened in China are 144?146MHZ and 430~440MHZ, which are also commonly used in countries all over the world. In October 2001, the Radio Frequency Plan of the People’s Republic of China issued by the National Radio Administration of the Ministry of Information Industry specifically stated for amateur radio enthusiasts and amateur services. “Amateur service: self-training and mutual communication for amateur radio enthusiasts. Radiocommunication services for technical research. Amateur radio enthusiasts refer to those who are formally approved and interested in radio technology, whose interests are purely personal hobbies and do not involve profit.”

Note for walkie talkie use:    

1.Why the antenna of network mobile radio is not external?
Re: Because the antenna will lose signal in the process of transmitting.
The longer the length of the antenna, the greater the loss.

In order to reduce the signal lose,and the engineer use the best feeder line.
They reduce the antenna length to 1 meter for testing,and turns out the internal antenna has better signal than external antenna.
Also test 1.5~2.5m.the result is the same.the internal antenna has the better signal.

2. Why do traditional platforms use external antennas?
Re: Because the traditional mobile radio use low frequency 400Mhz,the antenna signal lose is very small.
The network mobile radio is high frequency 2000mhz,the antenna lose is large

3. The main antenna mainly depends on the area of the antenna. The size of the radio is large, so the antenna area can be 4-5 times of the cell phone antenna, and the effect will be better than the external antenna.And the cell phone is also a built-in antenna that can be used well.

4. Why it can be external of the GPS antenna ?But the network antenna is not recommended external?
Re:Because the GPS antenna has power, it can be took the power signal, but the network antenna has no power, it can only take the frequency and loss is large.
