About Telkonet The Telkonet PlugPlus(TM) family of networking and internetworking products offers a viable and cost-effective alternative to the challenges of hardwired and wireless local area networks (LANs) due to the fact that Telkonet products provide connectivity over existing electrical wiring and do not require the costly installation of additional wiring or major disruption of business activity. Telkonet PlugPlus products are designed for use in commercial and residential applications, including multi-dwelling units and the hospitality and government markets where the Telkonet system can, in many cases, be implemented more quickly and less expensively than adding dedicated wiring or installing a wireless system.
