Various Types And Features Of A UHF RFID Reader

By Jose Carter


In the last few decades, the engineering sector has incorporated the evolving technologies for the need to structure sophisticated devices that have wide applications in diverse sectors. This motive led to the invention and renovation of UHF RFID reader which has a superfluity of applications in many fields. It uses the electromagnetic waves to track the tagged items. It is usually installed with a GPIO and an API that provides communications between the software used and its hardware components.

Reader models in the current market are launched into two broad classes that have an intensive use in the industrial setting. One of them is the fixed reader that come up with two, four or eight antennas ports. They are featured by their high task performance and increased sensitivity to the stationary applications. They are also fitted with subsystems that offer a moderate aggregate performance.

The other type is composed of mobile brands that are highly flexible in terms of their functionality proximity. They have a single antenna that is integrated into the system. They lack ports that support additional antennas. This is well restituted by their ability to perform a superfluity of programs due to the on-board processing feature. They further use in-house developed package for them to function.

The readers are usually structured with certain specifications that make them unique in terms of comparison to other types of readers in the market. Their power specifications consist of a slew of suitable options. You can use the power adapter, power over Ethernet, battery or the customized in-vehicle option for vehicles and forklifts. The powering style used determines the proximity of installation of the devices.

In addition, they are also featured according to the networking technology used to carry out their tasks. They are usually interconnected with a reliable source of the network that offers a stream-able data transmission and connectivity. Others are plugged into a host computer which limits their mobility. The connectivity adopted mainly revolves around; Wi-Fi hot-spots, Bluetooth connectivity, Local Area Network, use of serial ports as well as secondary connectivity ports.

In addition, their reading rate is also depended on the amount of the available antenna ports. This is solely determined by the intended application requirements which are dictated by reading zones. Fixed readers with a specified amount of antennas are set to cover one zone or a few varied ones depending on the tagged items and its speed. Integrated antennas are used in applications with a small read zone to carry task like retail or file tracking.

Moreover, the systems also come with additional utilities in order to provide new functionality that can foster the current system. One of the added utility is the HDMI which allows a display to be directly plugged into the device. Other includes the USB ports, GPS for the mobile types used in large deployments, and a camera for applications used in remote areas for documentation of the tagged item status. Cellular capabilities are also installed for readers that operate in regions with no Wi-Fi.

Therefore, the ultra-high RFID reader portrays an optimal functionality as a result of a full operation-ability of its software and hardware components. The device undergoes a series of structural innovations to make it fit in the current rapidly evolving environment. This has favored the engineering of more customized readers to boost their efficiency.
