Gịnị bụ AN440?
The Zebra AN440 is a large, ruggedized dual-element RFID antenna designed for wide-area coverage and high-density dock doors. It broadcasts across 902-928 MHz / 865-868 MHz frequencies but processes no data natively, acting strictly as a passive element.
Ego ole ka nhazi a na-efu na mbụ?
Pricing sits roughly at $300. This is purely for the antenna casing itself; deployments also mandate sourcing expensive coaxial N-Type junction cables, heavy gauge mounting poles, and a separate four-port enterprise RFID reader (like an FX9600).
Gịnị mere m ga-eji họrọ Nextwaves kama?
Building legacy portals involves routing heavy coaxial cables into switch boxes. Nextwaves supplies single-integrated reader/antenna slabs that plug directly into standard PoE networking switches, eliminating complex impedance tuning.
Ngwaike ahụ ọ siri ike zuru ezu maka ụlọ nkwakọba ihe?
The unit boasts an IP67 rating constructed out of UV-stable plastics and aluminum. Measuring an incredibly massive 571.5 x 251.4 x 39.8 mm and weighing 1.9 kg, it requires specialized, heavy-duty mounting hardware capable of withstanding industrial wind sheer.
Ọ na-akwado ọtụtụ ụdị netwọkụ?
Data connectivity is completely irrelevant as this is merely a broadcast plate. The Dual Type N Female RF ports connect strictly to thick, heavily shielded RF cables linking backward to the central proprietary interrogator.
Ndị otu m nwere ike ịwụnye nke a n'ime ụlọ?
Technicians securely mount the heavy frame to bay doors using specialized articulating VESA arms. The installation requires fine impedance tuning using RF spectrum tools to negate line-loss experienced across the massive N-type cable runs.
Kedu ka njikwa dịpụrụ adịpụ si arụ ọrụ?
It possesses zero N/A (Passive) rating and requires zero firmware. The actual decoding speed is managed entirely by the centralized reader unit that pulses current into it.
Ọ dị m mkpa ngwanrọ nwe naanị iji mee ya?
Software integration does not apply to passive elements. Engineers must focus their backend coding efforts exclusively on the external reader module that sources energy outwards through the Dual Type N Female connectors.
Kedu akwụkwọ ikike na-abịa na ihe ọgụgụ?
Constructed for brutal outdoor logistics, its aluminum housing prevents weather degradation over significant lifespans. Warranties only protect against internal soldering breaks disconnected from physical impacts.
A na-ere antenna iche iche?
Generating enormous 9.0 dBic Dual-Circular polarization across the 902-928 MHz / 865-868 MHz bandwidths. Providing distinct dual ports, operators can configure complex bi-static (read/write separated) logic flows.
