### 4. Functionality

The RFA-O4-NM2-WG operates as an omni-directional antenna, radiating RF energy uniformly in all horizontal directions. This design makes it ideal for central access point installations where uniform coverage around the antenna is required.

Working Principle:
The antenna converts electrical signals from a wireless transceiver into electromagnetic waves and vice versa. Its 4dBi gain provides moderate amplification, extending the effective range without creating narrow beam patterns. The vertical polarization ensures compatibility with most WLAN devices and access points.

Use Cases and Applications:
- Outdoor Wi-Fi access points and base stations
- Industrial wireless LANs (IEEE 802.11b/g/n)
- Point-to-multipoint wireless bridges
- Wireless video surveillance systems
- Smart city and IoT network deployments
- Outdoor hotspots and campus networks
- Long-range wireless sensor networks

Compatibility:
- Compatible with ORing’s RF cables (e.g., RFC-NM-SMR-150, RFC-NM-SMR-1000)
- Works with RF surge protectors (RFP-NF-NM-WG) for lightning protection
- Can be mounted on magnetic antenna bases (RFB-M2-150, RFB-M2-1000)
- Integrates with ORing’s industrial routers, access points, and wireless bridges
