Ethernet Radio

Point-to-point wireless links are used when fiber optic or cable connections are challenging or when quick connections are needed.
Line-of-sight (LOS) is optimal for 2.4 GHz wireless links. Near-line-of-sight (NLOS) and non-line-of-sight (NLOS) connections are possible at different frequencies.
Wireless links operate in 2.4 GHz or 5.8 GHz frequency bands, adhering to WPC (Wireless Planning & Coordination Wing) regulations.
Transmitted power levels are limited by WPC's specifications, depending on frequency.
Throughput ranges from 25 Mbps to 750 Mbps, with potential to cover distances exceeding 50 km.
These links support various data types (voice, data, video).
Each link comprises an indoor unit (IDU), outdoor unit (ODU), external antenna, and a CAT-5e cable.
Integrated outdoor unit/antenna models are available.
Software for configuration and management is crucial.
Ethernet Radios can be used for diverse applications: building connectivity, high-speed internet access, replacing leased lines, video surveillance, voice over IP, and multimedia.
Point-to-point or point-to-multipoint configurations exist.

Security Considerations

Wireless links are vulnerable and security measures may include:
Linking outdoor units to prevent unauthorized use.
MAC Authentication is recommended to secure the links.
Two-way locking for increased security is preferred.
Encryption (IEEE 802.11i/ FIPS-197) is crucial for data security.
A stable power supply is needed to ensure uninterrupted operation of the Ethernet radio system.
