Recently they have added innovative products like networked CCTV, Cloud based storage, wifi extender, tablets etc.
The company does seem to have a monopoly in terms of brand name and marketing in the networking domain. In my circle of competence I have observed Dlink being used in LAN/ OFC cables, Switches, Hubs, Wifi Routers etc,
SHIFT FROM VOICE CALLING to DATA SERVICES (i.e. broadband, 3G/ 4G). Over the next few years, I expect internet enabled calls to completely replace voice calling. The fact that homes, offices and digital work culture makes us more dependent on wi-fi (or internet). Further, with time more and more people are going to opt for broadband/ wi-fi connections at homes and offices. D-link also provides security and surveillance equipment including cameras and home automation equipment. I am bullish on security and surveillance related themes also.
