1. Overview of Handheld Terminal Technology

Handheld Terminal is a portable intelligent device that integrates data collection, processing and transmission functions. It has become one of the core tools for the digital transformation of modern enterprises. As an important carrier of mobile computing technology, handheld terminals integrate three core technologies: automatic identification, wireless communication and mobile computing, and show unique value in improving operational efficiency and optimizing work processes.

From the perspective of technical composition, modern handheld terminals usually include the following core modules:

Hardware system: including computing components such as processors, memory, storage, and data acquisition components such as cameras, scanning engines, and RFID readers

Operating system: Android is the mainstream, and some industrial scenarios still use systems such as Windows IoT

Communication module: supports multiple wireless communication protocols such as 4G/5G, Wi-Fi 6, and Bluetooth 5.0

Human-computer interaction interface: multi-mode design such as touch screen, physical buttons, and voice interaction

As an advanced form of handheld terminals, mobile computers integrate more powerful computing power and richer functional modules. Modern industrial-grade mobile computers not only have the data collection function of traditional handheld terminals, but also can run complex business applications and support real-time data analysis and decision-making.

According to the latest data from VDC Research, the global handheld terminal market will reach $5.8 billion in 2023, of which products with integrated handheld RFID functions account for more than 40%. It is estimated that by 2028, the market size of mobile computer products supporting RFID reading will exceed $10 billion, with an annual compound growth rate of about 11.5%. This growth is mainly driven by three aspects: first, the acceleration of digital transformation in the retail industry, second, the surge in demand for intelligent transformation in the manufacturing industry, and third, the strong demand for efficiency improvement in the logistics industry.

2. Technological evolution of handheld terminals

(I) Review of development history

The technological evolution of handheld terminals can be divided into four key stages:

The first stage (1990-2000): the period of single function

Early equipment is represented by Symbol Technologies' PTT series, which is mainly equipped with barcode scanning function and uses a proprietary operating system. The equipment weight generally exceeds 1 kg and the battery life is only 3-4 hours. The products in this stage are mainly used in warehousing and logistics fields, and the functions are relatively single.

The second stage (2001-2010): Technical standardization stage

With the popularity of Windows CE system, the MC series launched by Motorola (now Honeywell) has become an industry benchmark. The device began to support handheld RFID reading, the protection level was upgraded to IP54, and the battery life was extended to 8 hours. The important breakthrough during this period was the widespread application of the EPC Gen2 standard in 2006, which solved the compatibility problem between different devices.

The third stage (2011-2020): Intelligent transformation period

The introduction of the Android system has completely changed the application ecology of handheld terminals. The new generation of products represented by Honeywell's CT series integrates edge computing capabilities, supports multi-mode data collection (RFID+barcode+image), and has cloud data synchronization functions. Industrial design has also made significant progress, with the weight reduced to about 600g and the protection level generally reaching IP65.

The fourth stage (2021 to present): Fusion and innovation period

Currently, mobile computer-type handheld terminals are showing three major development trends: one is the full support of 5G technology, the second is the integration of AI acceleration chips, and the third is the integration of AR/VR functions. Honeywell's latest CT60 series is equipped with Qualcomm QCS6490 processor, with AI computing power of 15TOPS, supporting real-time object recognition and analysis, and powerful handheld RFID reading capabilities.

(II) Core technology breakthroughs

The technological innovation of modern mobile computer-type handheld terminals is mainly reflected in four aspects:

1. Processor performance leap

Mainstream devices have upgraded from single-core ARM processors to eight-core/ten-core architectures, with computing power increased by more than 20 times. Taking the Snapdragon 660 used in Honeywell CT40 as an example, its performance is close to that of mid-range smartphones, and it can smoothly run complex business applications while processing handheld RFID data collection tasks.

2. Data collection technology innovation

The new generation of handheld RFID scanning engines can read at a speed of up to 1,000 times/second, and the UHF band reading distance exceeds 12 meters, while supporting batch reading of 300+ tags. In addition, the introduction of computer vision technology has enabled mobile computers to have the ability to associate image recognition with RFID data.

3. Comprehensive improvement in communication capabilities

Supports 5G SA/NSA dual-mode, Wi-Fi 6 and Bluetooth 5.2, with a theoretical transmission rate 10 times higher than 4G. Datalogic's Skorpio X5 also innovatively uses MIMO antenna technology, which greatly improves the quality of handheld RFID signal reception, especially suitable for high-density tag environments.

4. Optimized human-computer interaction experience

The 6-inch full HD touch screen has become standard for mobile computers, and some models support glove and wet hand operation. The introduction of voice interaction function has increased the efficiency of handheld RFID operation by more than 40%, and the AR visualization interface has greatly reduced the difficulty of tag positioning in complex environments.
