      "question": "What EIRP does a fixed UHF reader transmit?",
      "answer": "Regional firmware limits the EIRP. FCC firmware (US, Canada ISED) allows +36 dBm EIRP (4 W) under 47 CFR Part 15.247 with a 6 dBi antenna and the appropriate duty cycle. ETSI firmware (EU, UK) allows +33 dBm ERP (2 W ERP = +35 dBm EIRP) under EN 302 208 v3.3.1. SRRC firmware (China 920-925 MHz) allows +33 dBm EIRP. ARIB (Japan) allows +33 dBm EIRP. Every reader in this catalogue is software-adjustable per port from +10 dBm up to the regional maximum."
    },
    {
      "question": "How many antennas can I connect to one reader?",
      "answer": "Most enterprise fixed readers ship in 4-port or 8-port variants. Impinj R700 and R420 come in 2-port, 4-port and 8-port SKUs. Zebra FX9600 ships in 4-port and 8-port. CAEN R1260 is 4-port. For >8 antennas per zone the architecture is either (a) multiple readers on an LLRP fleet, or (b) an antenna multiplexer (Impinj xArray, Times-7 MUX). A single R700 cycles through its 8 ports in a round-robin RoSpec; a typical cycle completes in 200-400 ms depending on antenna-dwell configuration."
    },
    {
      "question": "Is LLRP required or can I use only the vendor SDK?",
      "answer": "Vendor SDKs are convenience wrappers over LLRP under the hood (Impinj Octane SDK, Zebra RFID SDK, CAEN easy2read). You can integrate with the vendor SDK without ever writing raw LLRP. LLRP direct is the right choice when (a) the deployment mixes multiple reader vendors, (b) you need full control over RoSpec / AccessSpec for edge cases (BlockWrite, Kill, Lock, dense-reader mode), or (c) the integrator is an RFID middleware vendor building a vendor-neutral ingest. Most single-vendor deployments use the vendor SDK."
    },
    {
      "question": "Can a fixed UHF reader encode tags, or only read?",
      "answer": "All readers in this catalogue support the full EPC Gen2 write command set (Write, BlockWrite, Lock, Kill, Access) via LLRP AccessSpec. In practice fixed readers are rarely used for bulk encoding because the geometry (multi-antenna, 2-4 m range) makes addressing a specific tag unreliable. For high-volume encoding the normal architecture is a dedicated RFID printer-encoder (Zebra ZT411R, SATO CL4NX-J RFID) with a near-field antenna tuned for 5-10 cm write distance. Fixed readers are appropriate for one-off tag updates (aggregation, commissioning, inventory-state changes) in-place."
