Advantages of semi-active RFID
Compared with active RFID products:
Semi-active RFID products do personnel positioning management, the
positioning accuracy is more accurate, and can be positioned in each room;
To achieve the same positioning accuracy, the cost of semi-active RFID
products is much lower, and to achieve the same effect, the cost is basically
half of that of active RFID products;
Semi-active RFID products have a smaller recognition distance error, about
10cm, while active RFID can only be a rough fuzzy distance, the signal is
erratic, and there is no way to be accurate;
Semi-active RFID tags, usually in a dormant state, do not consume power,
and are very power-saving. The battery can be used for 5 years, while active
RFID tags usually send signals continuously, which consumes a lot of power.
Relative to GPS satellite positioning:
Semi-active RFID product positioning can accurately locate every room in
each building, while GPS positioning can only go to a certain area of a
certain area of a city, a certain street, a certain building in a
community.
Relative to the mobile phone area positioning:
Semi-active RFID product positioning can accurately locate every room in
each building, while mobile phone positioning can only go to a certain area of
a certain area of a city, a certain street, a certain building, and a
certain building.
To sum up, in comparison, semi-active RFID technology products have their
own unique advantages in terms of economic cost, positioning accuracy and
effect, which is why we initially chose semi-active RFID technology as our
company. The reason for the core technology.
