| Post subject: | Hybrid Radio Networks - RF Layers |
Current literature in MRT Journal, Mission Critical Magazine, this website, and weblogs such as WiFi News, talk about the variety of RF in licensed and unlicensed frequencies and the fact that RF spectrum is now connected to the internet. Operators, network managers, and CIOs now must contend with a variety of decisions in how to best utilize the variety of available networks in a hybrid network manner. For example, let's say you are an operatore of a large 802.11 WiFi network for a city. How does the 802.11 network fit your data needs? How does the 802.11 WiFi network layer onto your private radio system? The radio system can pass and send voice and data but certainly the radio band is a "narrow" band when compared to the "broader" band of an 802.11 WiFi broadband network. Furthermore, how do the hybrid networks fit into an "I.T. internet protocol" strategy? Is there a "grand I.T. strategy" that needs consideration when deploying a communication system? I think the answer is yes and this website is quite helpful in understanding some of the issues. Hope you all had a great Easter. FLX |

Sean - Interesting information and approach by COCO How CoCo works: The software sits on top of existing networks and acts like a conference call, allowing individuals and other networks to connect. "The CoCo protocol is the fabric that sews it altogether," said Peter Erickson, vice president of business development. In practice: With the software, a handheld device equipped with only a wireless Internet chip can act like a walkie-talkie and communicate with UHF or VHF radios. The device can also connect to a wireless Internet access point and view video. It can also make phone calls without a cellular connection. The only requirement is that it is in line of sight with another device using CoCo. See weblink: http://seattletimes.nwsource.com/html/b ... ace06.html Here are some other interoperability products 1) Motorola Motobridge used in State of Florida for state interoperability. http://sion.motorola.com/pages.aspx?pag ... escription 2)Cisco IPIC rsystem with routers http://www.networkworld.com/news/2005/1 ... radio.html 3)the interoperable switch by Raytheon http://www.jps.com/index.asp?node=118 |
