Sidebar: Glossary -- Wireless Mesh Networks
Dec 22, 2008,
- Mesh Network: a communications network composed of radio nodes organized to overlap one another in a mesh topology. The nodes work in harmony with each other creating the "cloud" or network.
- The 4.9 GHz band is licensed-protected spectrum with sufficient capacity for video surveillance. Licensees are authorized to operate on an authorized channel in this band for 10 years.
- The 2.4 band has 14 frequency channels, 11 of which are permitted for unlicensed use by the FCC. The 2.4 band is limited by the number of non-interfering channels available.
- Single-Radio Architecture: Uses same frequency for access and backhaul and is subject to interference as the number of users increases.
- Dual-Radio Architecture: Separates access frequency from backhaul frequency limiting interference, though still can suffer interference on the backhaul.
- Multiradio Architecture: Has dedicated, separate radios for the access and each backhaul route, ensuring there's no interference between nodes.
