Hotspot NetworksThe first-to-market, detailed guide to hotspots--the "killer app for 802.11"--provides need to know information on these open-to-the-public wireless networks that are springing up in hotels, airports, cafes, and even parks. Using this resource, engineers can cost, design, configure, implement, and install hotspots, or develop service applications in this hot new market. Written by Dan Minoli, one of the top voices in networking, this reference tells readers how to deliver wireless Internet and telecom that's 40 times faster and 1/10th the cost of conventional networks. |
