General Advice Wireless technology is solving the bandwidth crunch Wireless technology is coming of age. Our appetite for bandwidth is insatiable Wireless has always been an alternative for high-speed connections, but never has the range of choices been as great nor the rate of innovation as rapid Wireless technology is rapidly evolving to become • easy to use • cost efficient • flexible in network design • secure and reliable • quick to deploy • with smooth upgrade path and no need for retraining With technology becoming cheaper, broadly deployed and easy to use, more off-the-shelf applications are becoming available to meet the surge of demand. - join the 27 million mobile professionals enjoying • connections when no others are possible • connections at lower cost in many scenarios • faster connections • backups to landlines • networks that are much faster to install Wireless video communication systems are achieving the performance of traditional microwave transmission products at a fraction of their cost. Simple to install and operate, the user can perform tasks with minimum amount of support from distributor or manufacturer. No license required. Two categories: • low power fixed points – easy to set up and maintain. o Video conferencing o Distance learning o Security and surveillance o Video distribution • low power mobile links - performance varies according to antenna selection, location and site configuration. Experience necessary. (Internal interference (multipath) results from reflected signals from the transmitter interfiering with the direct signal at the receiver) - companies that specialize in wireless integration will be able to assist with a site survey. Software packages that characterize the terrain of particular areas may be helpful Fixed wireless devices usually derive their electrical power from the utility mains, unlike mobile wireless or portable wireless that tend to be battery-powered. (mobile and portable systems can be used in fixed locations, efficiency and bandwidth are compromised compared with fixed systems). Mobile or portable, battery-powered wireless systems can serve as emergency backups for fixed systems in case of a power blackout or natural disaster. Unlike cellular and other mobile wireless systems, fixed-wireless systems use fixed antennas with narrowly focused beams. A 3 degree to 4 degree beam is not uncommon. And unlike cellular systems, in which base stations communicate with dozens of mobile stations, broadband systems usually operate in a point-to-point manner, though a number of point-to-multipoint systems are in development Middleware Integrating systems and applications. Internal systems must be able to talk to one another before they can interface effectively to external suppliers, customers, and other trading partners over the Internet. The term Middleware is used to describe a broad array of tools and data that help applications use networked resources and services. This market is expected to expand aggressively. The potential demand far outstrips the present capacity of present solution suppliers, and is growing at a rate of 1000% annually. Solution suppliers are continually developing middleware that is • More user friendly • Better optimized to CPU architecture • More efficient at doing more with less. A successfully integrated wireless system enables collaborative operation and ‘smart working’, increasing the speed of business reaction time, reducing costs, and facilitating seamless straight-through transaction processing.
