    NEW Marktrace MR3848 RFID 2.4G Active Tag 2.4 GHz 80 Meter Module Card
    2.4GHz RFID refers to a system using active RFID tags and readers that operate on the 2.4GHz frequency band to identify and track items or people . This technology is characterized by long read ranges, active power sources (like batteries), and strong anti-collision capabilities for reading multiple tags simultaneously. Common applications include asset management, personnel tracking, attendance management in schools, and various industrial automation scenarios.

    AI Overview
    WLAN Frequency Bands ⋆ | WiFi Frequency Bands | 2 GHz vs 5 GHz
    The 2.4 GHz radio frequency band is a globally harmonized, unlicensed radio frequency used by many devices, including Wi-Fi, Bluetooth, cordless phones, and microwave ovens . It offers a good balance of range, with signals able to penetrate obstacles like walls more effectively than higher frequencies. However, its popularity also makes it prone to significant interference and slower speeds compared to other bands, such as 5 GHz.
    Key characteristics:
    • Range:
      2.4 GHz signals have a longer range and can penetrate solid objects like walls and floors better than higher frequencies.
    • Speed:
      It is generally slower, with speeds often maxing out around 100 megabits per second (Mbps), compared to 5 GHz and higher bands that can exceed 1 gigabit per second (Gbps).
    • Interference:
      This frequency band is often overcrowded due to the high number of devices that use it, leading to significant signal interference.
    • Wavelength:
      It has a longer wavelength, approximately 12.5 cm, which contributes to its greater ability to travel farther and penetrate objects.
    Common uses:
    • Wi-Fi :
      Opens in new tab
      Many Wi-Fi networks use this band, especially for devices in different rooms or further from the router.
    • Bluetooth :
      Opens in new tab
      Bluetooth technology operates in the 2.4 GHz band for short-range device connections like headphones and smartwatches.
    • Cordless phones :
      Opens in new tab
      These devices, along with baby monitors and other household gadgets, also utilize the 2.4 GHz band.
    • Microwave ovens :
      Opens in new tab
      The 2.4 GHz frequency is also the resonant frequency of water, which is why microwave ovens operate at this band.
    Advantages:
    • Good coverage:
      Ideal for reaching a wide area and providing connectivity to devices located far from the router or in other rooms.
    • Penetration:
      Better at passing through solid objects, which helps maintain a connection in a cluttered environment.
    Disadvantages:
    • Congestion:
      The high number of devices using this frequency often leads to signal congestion and interference, which can reduce speed and stability.
    • Lower speed:
      Typically offers slower data transfer rates compared to higher frequency bands like 5 GHz.

    Can you be tracked with an RFID tag?
    The phrase 'tracking people' along with 'RFID', is commonly misunderstood and misinterpreted as people can be “tracked anywhere” with an RFID tag . However, RFID tags must be within a certain read range of compatible equipment in order to be read, usually between 1 – 20 meters.
