# 4 Port RFID Reader
## What is a 4 Port RFID Reader?
A **4 port RFID reader** is a versatile device designed to manage multiple RFID antennas from a single control unit. In my experience working with access control systems, deploying a multi-port reader significantly streamlined operations at a corporate headquarters. We needed to monitor both pedestrian and vehicle entrances simultaneously, and the **4 port RFID reader** provided the perfect centralized solution. My technical aptitude allowed me to configure the zones effectively, assigning specific antennas to different doors and gates.
### Technical Specifications and Parameters of a 4 Port RFID Reader
When selecting a **4 port RFID reader**, understanding its technical capabilities is crucial. Here are detailed specifications for a typical high-performance model. *Please note: These technical parameters are for reference data; specifics need to be confirmed by contacting backend management.*
* **Physical Dimensions:** Main Unit: 180mm (L) x 120mm (W) x 35mm (H). Each antenna port supports standard SMA female connectors.
* **Operating Frequency:** 860 MHz ~ 960 MHz (UHF), complying with global regional standards like ETSI EN 302 208 and FCC Part 15.
* **Protocol Support:** ISO/IEC 18000-6C (EPCglobal Gen2).
* **Read Range:** Adjustable from 0.5 to 12 meters per port, depending on antenna gain and tag type.
* **Interface:** Ethernet (10/100 Mbps TCP/IP), RS-232, RS-485, and Wiegand output for seamless integration with existing systems.
* **Power Supply:** 12V DC, 2A.
* **Chipset/Processor:** Typically integrates a dedicated UHF RFID processor (e.g., Impinj R2000-based solution or similar proprietary chipset).
* **Multi-Port Management:** Supports anti-collision algorithms to handle over 200 tags per second across all four ports.
#### Key Features and Applications
The primary advantage of a **4 port RFID reader** is its consolidation of functionality. I firmly believe that for medium to large-scale installations, this architecture offers superior reliability and easier maintenance compared to deploying multiple single-port readers.
