WiFiRanger utilizes its proprietary firmware along with a combination of custom and vendor-supplied hardware. You may be able to use off-the-shelf hardware to perform some of the same functions as a WiFiRanger, but you will not achieve the functionality of an actual WiFiRanger device. WiFiRanger products are the result of over a decade of focused development, both mechanical and firmware, to create the highest performance and most user-friendly solutions for the mobile industry. A DIY solution often poses several technical and usability issues that are unforeseen during the purchasing stage. Once purchased, several Do-It-Yourselfers have contacted us to see if they can purchase a WiFiRanger system directly to overcome the deficiencies of their DIY kits.
