Ajụjụ A Na-ajụkarị
Gịnị bụ S9028PCL/PCR?
The Laird S9028PCL (Left-Hand) and PCR (Right-Hand) are ruggedized, circularly polarized passive antennas. Locked strictly to the 902-928 MHz (FCC) North American block, they project high-gain beams when excited by external active transceiver logic.
Ego ole ka nhazi a na-efu na mbụ?
A raw plate costs roughly $150. Integrators assume the subsequent costs of securing high-end RF reader controllers, shielding coaxial cable trenches, and engineering the required Linux-based software routing frameworks.
Gịnị mere m ga-eji họrọ Nextwaves kama?
Building portal chokepoints using discrete RF antennas entails painful impedance engineering. Nextwaves consolidates both the powerful RF board and the IP gateway inside one sealed panel, removing external logic entirely.
Ngwaike ahụ ọ siri ike zuru ezu maka ụlọ nkwakọba ihe?
Operating inside an IP54 weather-resistant shell, it measures roughly 260 x 260 x 33 mm and weighs 1.04 kg. It readily handles dense warehouse grit but lacks sealing necessary for intense wash-down cycles.
Ọ na-akwado ọtụtụ ụdị netwọkụ?
Network routing is completely non-applicable to physical broadcast plates. All connections occur physically over Coaxial Type N / SMA edge sockets trailing strictly back to the active master block.
Ndị otu m nwere ike ịwụnye nke a n'ime ụlọ?
Physical setup involves aiming the plates accurately along heavy-duty VESA arms. Network engineers must use expensive VNA spectrum analyzers to assure proper RF alignment and calculate decibel line-loss over the coaxial lengths.
Kedu ka njikwa dịpụrụ adịpụ si arụ ọrụ?
With a N/A (Passive) rating, read volumes depend exclusively upon the parent system driving the board. Expanding throughput necessitates replacing the parent reader matrix, not the passive plate itself.
Ọ dị m mkpa ngwanrọ nwe naanị iji mee ya?
There is zero software logic present. Programmatic interfaces must be directed towards the SDKs controlling the central interrogator box supplying current through the coaxial leads.
Kedu akwụkwọ ikike na-abịa na ihe ọgụgụ?
Like most large passive elements, the rugged fiberglass radome shields the array components securely, offering standard 1-year defenses against purely manufacturing-related breakage.
A na-ere antenna iche iche?
Pushing an aggressive 8.5 dBic output, operators typically alternate Left and Right Hand (PCL/PCR) models on opposing portal walls across the 902-928 MHz (FCC) band to destroy complex multipath nulls.
