2.4GHz Active RFID System |
Excellent Performance for Different Applications
Passive RFID (battery-less) is very popular in logistics
for its low cost, however, it is subjective to too many
constraints such as liquid and metal environment.
Usually passive RFID system requires careful trial
testing and tuning, in situations where items are more
valuable that you cannot afford missing; and the items
maybe not so RF friendly (liquid and metal); plus you
want to have a more automated and flexible system; then
an Active RFID system should be considered.

Agile Performance
The latest Active RFID system, HKRAR-EM series, consists of a
2.4GHz reader and different types of transponders which
actively transmit signals. It have excellent anti-collision
ability which scans 100 tags per second. Without
connecting to network, it can store up to 800 tags
information before network is back. Even the objects are
heavy metallic or liquid, the powered RFID tag can transmit
the ID back to system effectively. The battery life of tag
can typically run 5-10 years depends on RF settings and models.

High Reliability
Comparing with typical passive RFID systems, HKRAR-EM series
have high anti-jamming function in difficult environment
where non-friendly RF material is present.
New Wireless
Version
The HKRAR-EMWF (WF demotes
Wireless) can work as a
Mobile Reader or Data Collector. Now, the reader only requires a
power supply from a power adaptor or a portable battery. Through
IEEE 802.11b/g, the reader gathers the tag information and
transmit to the wireless router, which is a common network
infrastructure in many buildings. Once powered, HKRAR-EMWF is
instantly connected and become part of the system.

High Flexibility
Without the troubles of the wired network installation,
HKRAR-EMWF
provides a larger flexibility in designing the data
collector locations. In cases such as exhibitions, the booths
and area are subjected to change in each events.
HKRAR-EMWF
can
be easily relocated according to all specific situations.

Data gathering in Sensor Network
The robust Empress Active Reader is designed to work with
sophisticated sensor tags for applications like motion and
temperature monitoring. The fast data transfer enables short
data transfer time, it means a large amount of sensors can
perform download at once when they enter reading zone. |
