AWID LR-3000: LONG-RANGE RFID READER
The AWID LR-3000 is an Ultra-High-Frequency (UHF) long-range RFID reader primarily engineered for Automatic Vehicle Identification (AVI) and hands-free access system applications, such as gated communities, parking facilities, and industrial rolling gates.
KEY TECHNICAL FEATURES
Passive Tag Technology
This Awid RFID it operates using cost-effective, battery-free passive UHF credentials. Because the tags don’t rely on internal batteries, they offer an unlimited operational lifespan.
Adjustable Field & No Cross-Talk
Installers can program the RF power level and the read repetition rate in the field. This allows you to tighten the read zone diameter (typically about 6 feet wide at max distance) to prevent accidental lane cross-reading or “tailgating” triggers.
Optional Arming Control
The reader features a transmission control loop input. It can be paired with a buried vehicle loop detector or safety photo eye so that the reader only emits an RF field when a physical vehicle is present.
Credential Ecosystem Integration
The LR-3000 uses AWUD’s proprietary encryption for communication. It can seamlessly integrate with standard building access systems, allowing users to utilize dual-technology credentials (like the uAxcess series) where the same card works for long-range vehicle gates and close-range building doors.
Visual Status Indicators
Built-in dual LEDs provide instant visual feedback during installation and troubleshooting—steady Red indicates solid DC power, and a blinking Green verifies a successful tag read.
CORE SPECIFICATIONS AND PERFORMANCE
BENEFITS
PERFORMANCE AND OPERATION
Longer Reading Distance
Offers a tag reading distance of commonly up to 25 feet (7.6 meters), and sometimes more depending on mounting, credential type, and environment.
Eliminates Stop-and-Wait Entry
This Awid RFID allows vehicles to continue moving smoothly past the reader without stopping.
No Cross-Reading or Interference
Features programmable RF field strength and transmission only as needed to prevent cross-reading between lanes and interference between readers. An optional buried loop can also be used to arm the RF circuit.
Cost-Effective Credential Lifespan
Utilizes economical, passive, battery-free tags and cards that provide an unlimited operational life.
High Price-to-Performance Value
Delivers a distinct price and performance advantage over conventional long-range proximity card and active-tag RF systems.
DESIGN AND INSTALLATION
Single-Unit Construction
Features its electronics and antenna integrated into a single, small, compact, and attractive enclosure (9.8 X 9.8 X 1.3 inches).
Simplified Setup
Requires no reader programming and features simple wiring for easy installation. Installers also do not need FCC registration.
Weatherproof Design
Has an IP65 protection class rating, meaning it is suitable for outdoor use with direct exposure to the environment and requires no additional protective housing.
Clear Status Monitoring
Built-in dual LEDs provide easy status tracking, using a steady red light for power and a blinking green light for successful tag reads.
INTEGRATION AND FLEXIBILITY
System Interoperability
Can be interfaced with all standard access systems and AVI (Automatic Vehicle Identification) systems, supporting simultaneous Wiegand and RS-232 data outputs. It also shares the same code format as proximity readers.
Dual-Use Credential Compatibility
Can be combined with AWID’s uAxcess door access readers. This allows the exact same hand-held card to be used for both vehicle gate access at a parking facility and physical door access for people inside the building.
Versatile Tracking
Provides security and physical access tracking for varied applications, including vehicles at gates, people at doorways, wheelchairs at elevators, and gurneys at hospital entrances.
Wide Selection of Credentials
Supports a diverse range of passive vehicle-mounting tags (such as windshield, rearview mirror, sunvisor, sideview mirror, and metal-mount options) as well as hand-held cards.
Secure Communications
Assures facility security by utilizing AWID’s proprietary encryption for communications between the reader and its credentials.
HOW DOES IT WORK?
The AWID LR-3000 works by establishing a continuous, localized wireless communication zone using Ultra-High-Frequency (UHF) Radio Frequency Identification (RFID) technology.
GENERATING THE RF FIELD
FREQUENCY HOPPING
The reader continuously transmits a low-power, circular-polarized RF (Radio Frequency) field in the license-free 902 to 928 MHz UHF band. It uses frequency-hopping technology to prevent signal interference with other nearby wireless devices.
CONTROLLED TRANSMISSION (OPTIONAL LOOP ARMING)
To avoid unnecessary RF emission and prevent lane cross-reading, the reader can be wired to an optional buried vehicle loop detector. When a vehicle drives over the loop, it closes a circuit that “arms” the reader, causing it to transmit the RF field only when a vehicle is physically present.
ENERGIZING THE PASSIVE TAG
BATTERY-FREE ACTIVATION
When a vehicle equipped with an AWID passive tag (such as a windshield sticker or rearview mirror tag) approaches within its 25-foot range, the tag enters the reader’s circular RF field.
BACKSCATTER COUPLING
Because these passive tags are completely battery-free, they harvest electromagnetic energy directly from the reader’s signal to power up their internal microchip. The tag then alters and reflects (backscatters) the signal back to the reader, transmitting its unique encrypted ID number.
DECODING AND SECURE VALIDATION
PROPRIETARY ENCRYPTION
The integrated antenna captures the weak reflected signal from the tag and passes it instantly to the built-in reader electronics.
DATA VERIFICATION
The reader uses AWID’s proprietary encryption protocols to securely decode the communication. If the tag format matches (ranging from 26-bit to 50-bit Wiegand formats), the reader processes the data.
VISUAL CONFIRMATION
The moment a valid tag is read, the reader’s LED indicator blinks Green (while a steady Red light remains on to show the device has constant DC power).
RELAYING DATA TO THE ACCESS SYSTEM
SIMULTANEOUS DATA OUTPUT
Once decoded, the reader immediately sends the credential’s data out through its integrated 10-conductor shielded cable.
PANEL COMMUNICATION
It broadcasts this data simultaneously via Wiegand (up to 500 feet to a standard access system panel) and RS-232 (up to 75 feet to a local computer or serial device). The main access system panel then verifies if that specific vehicle ID has authorization to enter and triggers the gate operator to open without requiring the driver to stop.
