Types of Programmable Handhelds

Programmable handheld devices are small computing equipment. They are mobile and can be carried easily. Some programmable handheld computers have connectivity options and can be connected to the network. They are used in many industries, such as healthcare, logistics, and retail. Some of the handheld computers can be programmed and are used for specific applications.

The following are some of the types of programmable handhelds:

• Mobile Computer

These are handheld computers that can be easily transported. They are also referred to as portable computers. They have features like a display screen, memory, and an operating system. One can use them to perform tasks that are done on a desktop or laptop. Mobile computers are used to perform tasks such as reading barcodes and accessing databases.

• Handheld Barcode Scanner

These are devices that are used to read barcodes on products. They are small and can easily be held by the hand. They are commonly used in retail stores and warehouses. Handheld barcode scanners can be connected to a computer through a USB cable. Some are wireless and use Bluetooth technology to connect to a computer.

• Handheld RFID Reader

A radio frequency identification (RFID) reader is a handheld device that can use radiofrequency to identify and track tags that have been attached to objects. The RFID reader can be connected to a computer. It can also be a handheld device that is portable and used to read RFID tags. An RFID tag is a small object that can be attached to an object. The tag has a microchip that stores information about the item.

• Multifunction Test Computer

This is a handheld device that is used to test different things. It is used in industries like manufacturing and engineering. The device can be used to measure things like temperature, pressure, and voltage. It can also be used to perform diagnostics on other equipment.

• Mobile Point of Sale (mPOS)

This is a small handheld computer that is used by retailers to accept payments from customers. The mPOS can be a smartphone or a tablet that has a card reader attached to it. It can also have a barcode scanner to scan the products being purchased. The mPOS can connect to the internet using Wi-Fi or a cellular connection.

Functions and Features of Programmable Handhelds

Programmable handheld radios come with features that make them useful for various applications.

• Frequency Range:

Handheld radios are available in different frequency models to meet varied needs. The frequency range indicates how well the radio can communicate with other radios. VHF models are ideal for outdoor use, while UHF models work well for indoor use and outdoor with obstructions. Dual-band models can work with both VHF and UHF bands. The frequency range of radios is usually 136 to 174 MHz for VHF and 400 to 520 MHz for UHF.

• Power Output:

The power output of handheld radios is usually 5 watts, which is enough for short-range communication. Some models have lower or higher power output. Those with 7 watts can communicate over a longer distance. Users may need to get a license for radios with more than 2 watts of power output.

• Channel Capacity:

Handheld radios can have a channel capacity of 1 to 5000 channels. Most radios come with 16 to 128 channels, which is enough for most users. Radio systems with many users need radios with more channels, so they can assign a unique channel to each user.

• Scanning Mode:

Programmable radios have different scanning modes. The common ones include channel scanning, priority channel scanning, and multi-channel scanning. Channel scanning allows the user to scan all the channels to see which one is active. Priority channel scanning scans the priority channel first and then the other channels. Multi-channel scanning scans two or more channels at the same time.

• Noise Reduction:

Some programmable radios have noise reduction features to make it easier to communicate in a noisy environment. The features filter out background noise and make the voice of the user clearer. The radios also have VOX technology. It allows the user to talk without pressing the PTT button. The radio detects the voice of the user and transmits it when the user is done speaking.

Applications of the Programmable Handheld

Programmable handheld devices are used in various industries and sectors. They include the following:

• Healthcare: Handheld devices are used to scan the barcode of patients. Clinicians and nurses use them to administer medication, which helps prevent errors and ensures patient safety. Handheld devices are also used in diagnostic testing, where they provide instant results and help in making quick medical decisions. They are also used to monitor patients with chronic diseases.
• Inventory management: Programmable devices are commonly used in stock management. Workers use them to receive and transfer inventory data. They are also used to track shipments and ensure that goods are delivered on time. Handheld devices are also used to verify the accuracy of stock levels. They connect wirelessly to the main database to ensure that all the information is up-to-date.
• Manufacturing: Programmable devices are used in the manufacturing industry in several ways. They are used to monitor equipment and identify any problems. Handheld devices are also used to collect data and input it into the system. Workers can use them to scan barcodes and track the progress of a project. The devices help in reducing errors and improving efficiency.
