“Convergence” is a hot technology term that has many meanings, depending on which manufacturer is using the term. In my perspective, convergence is simply defined as: the integration of multiple technology platforms into one collective network infrastructure. One example is our Motorola Wireless LAN/WAN solution. The Motorola wireless solution creates a wireless backbone that allows complete integration between data systems. These systems might be: desktop or laptop wireless computers, PDA devices, touch screen devices, barcode scanners, and/or voice communication devices. These devices could be portable phones, PDA wireless phones, nurse call systems, and walkie-talkie devices. SVP technology (Spectralink Voice Protocol) provides the ability to operate voice communications over the wireless LAN/WAN. The wireless business class switch provides multiple wireless channels in which separate voice or data components can operate independently or as an integrated network. Security can be maintained at different levels for each channel. This means a typical wireless client environment can now have the best of all wireless worlds all managed by one wireless switch solution:

• An unsecured wireless data network for its visitors to use for internet access

• A wireless data network with high security for its own internal users

• A voice wireless network for its internal local mobile voice users

• Additional wireless networks for other solutions

In addition, the current wireless technology 802.11n provides fast, expanded bandwidth capabilities at 384mb versus the older technology which limited bandwidth to 56mb. Wireless networks are now secure, fast, and reliable; however, the design and installation of those networks can be challenging. Wireless network installations and the provider that installs these wireless network installations will often use the “pin-the-tail on the donkey” approach. This approach basically involves guessing the number of Access Points required and guessing where each of the Access Points should be located in the client facility. This creates an ineffective wireless LAN/WAN and destroys the clients’ perception of the stability and reliability of the wireless technology and network. The wireless network provider should have sophisticated wireless site survey software that allows the facility floor plan to be scanned into a file, which then integrates with computer hardware and software. The facility structural information is then input into the site survey software such as metal or wood studs, brick walls or drywall walls, false ceilings or fixed ceilings. This allows the site survey software to calculate baseline wireless transmission standards to then identify the number of Access Points required. It also identifies the location where the Access Points should be installed. Additionally, it tells us the required signal strength vs. the actual strength. Finally, it pinpoints any outside interference, the speed or bandwidth, and any other important measurements to ensure a reliable, stable wireless environment. The site survey software will be utilized by the installation team throughout the installation. My team has spent countless hours taking down wireless network systems that were not installed correctly. Therefore, it is highly recommended that a pre-site survey be performed by using sophisticated software to provide an accurate design and quote of what products are required for the wireless network. Once the wireless network is installed, a follow-up site survey should be performed to compare the design to the actual installation. Follow these simple guidelines and you will be a satisfied wireless network client.
