Overview Frequency Spectrum by its literal meaning is “any signal that can be represented as an amplitude that varies with time has a corresponding frequency spectrum”. In cellular industry parlance, frequency spectrum is of utmost importance since success & efficiency of every single key performance parameter of any cellular network depends on it. Since frequency spectrum is a national resource, therefore it should be distributed judiciously among all service providers (including ISPs). Government regulatory authorities play a key role in the distribution of frequency spectrum among service providers for their respective countries, globally. Present Scenario If we talk with respect ...Read more

CAPWAP networking protocol (RFC #5415) protocol as all Wi-Fi engineers would know is a widely used networking protocol that enables a central WLAN controller to manage a collection of Wireless Access Points, and most of the WLAN industry is using the CAPWAP in their solutions the same way. However, if we see little more into the CAPWAP semantics, CAPWAP networking protocol is designed very flexibly, and can be leveraged advantageously in multiple wireless scenarios and deployments. One such deployment scenario, I can think of is selective data path forwarding from an edge WLAN controller to a remote WLAN controller. But, ...Read more
It was only a few years ago that most western technology companies would think “software development” when asked “what does India represent to you?” While it certainly holds true today that India is a great source of software engineering talent, the bigger opportunity for western technology companies is to look at India in a comprehensive manner.
