en 4networking, recently unveiled a new PCI LAN adapter that allows users to stay connected to the network at 10 Mbps of speed while operating in the 5.8 GHZ band which guarantees interference free connections. These systems are priced at around $400 US. This means that Network administrators can use a Windows CE device that is Terminal Served into their workstation, and move about the building doing administrative tasks without being tied down. Microwave WAN configurations are also becoming very popular, due to their cost effectiveness, as well as relative ease of installation. Microwave communication is possible between sites approximately 25 to 30 Km apart. Distance of microwave communication is restricted primarily because of the curvature of the earth. Transmitter and Receiver tower height also affect this equation Obviously the terrain affects the equation as well. Microwave is popular in metropolitan areas and provides an effective means for signal transmission to various locales outside a metro area. There are several problems with Radio type transmission systems. Distortion becomes a very real problem. Signal distortion is not a matter that should be taken lightly. It happens in most transmissions, just like when lines that were originally designed for voice transmission are used for data transmission, some distortion occurs. Humans easily filter out distortion when it occurs by the human ear when it happens between 2 people having a conversation. This happens quite often. We become used to the noise or distortion, unless it is Beken 5extreme enough to create a problem communicating, we just drive on. This isn’t necessarily the case with data transmission. Since data is generally transmitted by electronics, of some kind, they have preprogrammed methods of dealing with distortion. Latency is a type of distortion. Many times it is called propagation delay. With the global reach of networks latency can, a...
