RFID Reader WH-SR1000
The RFID reader supports long distance indoor environment wireless communication with active
RFID tags, and basically provides 5 functions:
Private encryption protocol enforced wireless transmission to RFID tags;
Receiving encrypted wireless signals from RFID tags;
Transmission to the backbone via Ethernet;
Receiving signals from the backbone via cable and Ethernet;
Signal transferring, encrypting and decrypting between wireless channels and cable
communication
Similar to the base stations in telecom cellular network, each single RFID reader covers a cellular
zone, and hence multiple readers work together to cover certain area.

1. High sensitivity, supports long distance transmission and receiving up to 100m approximately
under ideal scenario. The actual covering radius still relies on on-site tests to determine.
2. Being with encrypted communication (private protocol), the reader strengthen the security at
3. With strong resistance to multiple sorts of interference, thereby guaranteeing the reliability at
4. Supports full-duplex communication with active tags Tag-RRL100 and Tag-DRL100, pass
operational signals to, and collecting feedback & heartbeat signals from those types of tags.
5. Simultaneously works with no more than 400 tags in the cellular zone, in order to guarantee
sufficient level of performance and availability.

RFID Tag Tag-RRL100 & Tag-DRL100
The two sorts of active RFID tags are specified to provide RFID technology supported interactive
functions, which includes:
Private encryption protocol enforced wireless transmission to a RFID reader through long
Receiving encrypted wireless signals from a RFID reader;
Switching on/off the lighting module controlled by receiving signals, thereby providing a visual
guiding function. A RRL tag has four lights in different colors, whilst a DRL tag has one in white;
Detecting the clicking of the button, and hence transmitting Feedback signal to a reader, which
can be seen as the trigger of certain IT functions;
Transmitting Heartbeat signal to a reader at a certain time interval as the indicator of its
operating status;
Features
1. Simultaneously operating without collision. A large group of tags can work within a limited area
2. The tags support full duplex communication, transmission and receiving took place
3. As active tags, Tag-RRL100 and Tag-DRL100 need batteries as their power supply; it is due to
their higher power consumption to support long distance transmission of wireless signals. For
the two types, their average total operating hours between recharges are 9 hours over 1.5 years
(self-discharge considered) or 240 hours (constant on);
4. The tag battery is monitored, and alert can be generated if the power level becomes

System: Interaction between RFID Reader and Tag
1. A round of operation starts with the RFID reader receiving a Switch-on signal from the
backbone system via Ethernet (cable) . The reader then converts the instruction to wireless
signaling, and broadcasts it via antenna RF1.
2. All tags (both types) in the coverage of the reader will receive the signaling via their receiving
antennas; after deciphering and processing the signaling, each of the tags obtains its target tag
ID and compares the ID with its own unique ID in its chip (EPC zone). If a tag whose ID is same
as the target ID, it will determine itself as the target tag and then switch on the LED on itself.
3. If the button of a tag (both types) is clicked, the tag will send a encrypted Feedback signal to the
reader via its transmission module. The signal is called Feedback because it is expected to take
place after lighting up and is prepared for sending back to activate certain following operation.
4. The reader receives the Feedback signal, deciphers, processes and converts it into a message,
which will then be sent to the backbone system via Ethernet.
5. The two types of the tags transmit their own working status signal (Heartbeat) to certain
readers at a certain time interval via their transmission modules.
6. The reader receives the Heartbeat signal, deciphers, processes and converts it into a message,
which would then be sent to the backbone system via Ethernet.
7. The two types of tags are designed to support full duplex communication. Above
communication 2 and 3, 2 and 5 can be carried out simultaneously; whilst 3 (press the button)
and 5(periodic heartbeat) can be carried out successively at a very short time interval.
