It is primarily used in Smart City applications to transmit data reliably from underground sensors—such as smart water meters, gas monitors, and sewer level sensors—to surface-level gateways." } }, { "@type": "Question", "name": "What frequency bands and wireless technologies does this antenna support?", "acceptedAnswer": { "@type": "Answer", "text": "This antenna is optimized for Low-Power Wide-Area Network (LPWAN) technologies. It typically supports NB-IoT, LoRaWAN, Sigfox, LTE-M, and standard 4G/LTE cellular networks, operating efficiently across Sub-GHz frequencies (such as 433MHz, 868MHz, 915MHz) and higher cellular bands." } }, { "@type": "Question", "name": "Is the manhole antenna capable of withstanding harsh street environments?", "acceptedAnswer": { "@type": "Answer", "text": "Yes, it is designed for extreme durability. The antenna features an IP68 waterproof rating to survive flooding and underground submersion. Furthermore, its heavy-duty radome provides a high IK impact rating (crush resistance) to withstand the weight of heavy vehicles passing over it." } }, { "@type": "Question", "name": "How is this low-profile antenna installed on a manhole cover?", "acceptedAnswer": { "@type": "Answer", "text": "The antenna is designed with a low-profile, dome or flat structure. It is typically installed via a secure through-hole screw mount directly onto the manhole cover. This flush-mount design prevents tripping hazards and avoids damage from street sweepers or snowplows." } }, { "@type": "Question", "name": "Can WHWireless customize the cable and connector for my specific underground sensor?", "acceptedAnswer": { "@type": "Answer", "text": "Absolutely. WHWireless offers full OEM/ODM customization services. We can customize the cable type, exact cable length, and s...
