IPIQ Network Installation Tips Clark Roundy Martin Boulter Using Wi-Fi Signal Mapping Technology as a Sales Tool By Clark Roundy, VP marketing & product management, & Martin Boulter, custom service manager, Luxul Installers of wireless networks can influence customer satisfaction by demonstrating a high level of expertise and knowledge specific to the customer’s network. There is a simple and cost-effective method for increasing your credibility as a wireless network integrator, while also adding real value to the solutions you offer and install. Wi-Fi is not an exact science and requires a certain amount of know-how to deliver reli-able and seamless coverage. Wi-Fi users can be demanding, and oftentimes skeptical about the value being delivered. What if you could show a customer a map of their entire building, com-plete with a graphical representation of actual wireless coverage? Take that concept one step further and show a comparison between old and new network coverage; or between alternative technologies. How would this improve your ability to demonstrate and charge for expertise, while also giving you confidence in making rec-ommendations that work? Such Wi-Fi Signal Mapping tools are readily available and simple to use…and the best news of all? Using this technology to deliver greater value to your Wi-Fi installations is FREE! Why Use Wi-Fi Signal Mapping Tools? 2. Compare different Wi-Fi technology options; 3. Identify potential problem areas; and 4. Optimize network coverage What Wi-Fi Signal Mapping Technology Should I Use? Because it is free and relatively ease to use, Luxul typically recommends Ekahau HeatMapper. HeatMapper allows for the cre-ation of a color-coded heat map showing wire-less coverage within a particular environment. Download for PC use at: http://www.ekahau. com/products/heatmapper/overview.html. For MAC users, Luxul recommends Netspot http:// www.netspotapp.com/. What Equipment is Needed? There are a number of ways network installers can use Wi-Fi Mapping tools to demonstrate value to their customers. As a manufacturer of Wi-Fi equip-ment, Luxul always recom-mends that installers use Wi-Fi Signal Mapping tools to: Using Wi-Fi Mapping tools requires only the following: UÊ"˜iÊ&#0a;œ“«ÕÌiÀÊqÊ7ˆ˜`œÜÇL>Ãi`ʏ>«Ìœ«Ê with a wireless network adapter.

When Mapping Signal Coverage, What Am I Looking For? Tools like Ekahau HeatMapper al-low for the creation of a color-coded heat map showing wireless cover-age within a particular environment. 1. Perform before and after compari-sons; The choice of router or access points (AP), antenna technologies, and other components will all have an impact on Wi-Fi network per-formance. When evaluating the wireless net-work signal reach and comparing different tech-nologies, test the following: Wireless Coverage – If a wireless network already exists or different technologies are being evaluated, test to determine wireless equipment capabilities and identify where there are holes in coverage. This will help to determine optimal device placement and equipment decisions. Distance – At short range, standard APs with dipole antennas will likely provide sufficient coverage. At longer ranges and wherever there are possible obstructions, other types of anten-nas (i.e., high-gain directional and Circular Polarized) as well as higher-powered AP tech-nologies should be considered. With Ekahau HeatMapper, multiple technol-ogies can be compared simultaneously to help determine an optimal solution for both cover-age and distance. Once setup, HeatMapper will identify the approximate location of each active radio on the map. When a highlighted radio is selected, the heat map for that radio is then displayed in colors that indicate the follow-ing: Blue (best signal available), Green (excel-lent signal), Yellow (very good signal), Orange (good signal), Red (poor signal), No Coloration (no signal) ÊqÊÃÊ`i“œ˜ÃÌÀ>Ìi`ÊLÞÊ̅iʅi>Ìʓ>«Ê in the image, the selected radio shows a good signal profile throughout a large portion of the building. Other active radios within the envi-ronment can also be seen, which can introduce signal and interference challenges that can now be more easily addressed. This can be a fantastic sales tool that demon-strates installer knowledge, while also ensuring optimal Wi-Fi network functionality. Mapping out the wireless signal can save time and effort by identifying potential issues before the instal-lation is complete. It’s also important to note that while signal strength is an important factor in a network deployment, data throughput is also an essential measurement of network efficiency and should not be overlooked. A properly functioning net-work must demonstrate both consistent signal stability and sufficient data throughput. Luxul recommends at a minimum the use of Internet Speed Tests to test basic bandwidth and the use of iPerf for more advanced measurement.
