A network bridge device filters data traffic at an inter-network boundary. Bridges reduce the amount of traffic on a local area network (LAN) by dividing it into two segments.
How Fast Is 802.11g Wi-Fi Networking?
The 802.11g standard for wireless networking supports a maximum bandwidth of 54 Mbps. Yet some 802.11g-compatible home networking products may advertise speeds of 108 Mbps or more. And neither number accurately reflects the real-world performance of 802.11g. How fast, then, is 802.11g Wi-Fi networking?
Wi-Fi Hotspots
Wi-Fi hotspots provide Internet access to wireless network devices in public locations such as downtown centers, cafes, airports and hotels. Businesses are increasingly using Wi-Fi hotspots for their internal (intranet) networks. Follow these guidelines to use WiFi hotspots most effectively.
Kbps, Mbps, Gbps
A data rate of 1000 bps is equivalent to 1 Kbps (or kbps); higher data rates are represented in Mbps and Gbps. Slow network interfaces like modems, and serial ports function at Kbps speeds.
