"I held a moment in my hand, brilliant as a star, fragile as a flower, a tiny sliver of one hour. I dripped it carelessly, Ah! I didn't know, I held opportunity", Hazel Lee.

Anjan Ghosal does not like letting a good opportunity slip away. After selling his Wi-Fi Data Offload business in 2011 in a very successful exit to Ruckus Wireless, he had the option to take some time off. "It was a great feeling! After many years of grinding effort, it was fun to prove a lot of skeptics wrong!" smiles Ghosal.

The explosive growth of mobile data has led to a number of challenge for mobile operators. Wi-Fi Offload addresses data traffic congestion in LTE networks – one of these key challenges. But there is a bigger challenge in managing signaling traffic – cryptic data messages that flow between the various network elements to keep them running. Signaling is the "central nervous system" of all telecom networks. If the signaling network fails, it will bring the entire wireless network to a grinding halt.

"In past lives we helped network operators manage their data traffic in 4G networks. The focus at Diametriq™ is to extend smart routing and management to their signaling networks."

As operators and standards bodies came together to address this issue by proposing specialized "signaling routers", Ghosal saw that as a golden opportunity. With a couple of employees, Ghosal started Diametriq to build intelligent routers to manage signaling routing in LTE networks.
