MetroPCS enters the VoIP age. Who will be next?

MetroPCS became the first US carrier to take the leap to voice-over-LTE, combining its voice, messaging and Internet services onto a single IP network. Verizon, AT&T, Sprint and T-Mobile have VoLTE plans of their own but they don’t necessarily have the same motivations for getting there.

Qualcomm, Ericsson just brought mobile calls into the IP age

Qualcomm and Ericsson have successfully passed a voice call from an LTE network to a 3G one, paving the way for mobile carriers to begin migrating their voice traffic onto all-IP 4G networks. Once that happens, operators can start shutting down their 2G and 3G networks.

I survived 2001, and even IPO’d! Lessons for weathering a downturn.

A market collapse, a cash crunch, and an IPO. I experienced it all in 2001. Now that another (even broader) recession is upon us, I offer my hard-earned lessons for “weathering through” uncertain economic times. (I write often about such topics my blog,Market Mine.)

We had $40M in revenue, and we were profitable, but when the bubble burst in spring 2000 – we ran into a cash crunch. We were growing the sales channel but also investing in infrastructure, so we knew we would need access to more capital soon.

But Simplex was an old style company, growing with a real product. In early 2000 I couldn’t talk eyeballs or click-throughs, so I had been unable to get attention from investment bankers. We just weren’t a sexy dotcom story.

Our line of credit was coming to its end and TransAmerica Finance was not going to renew it. They were scared, just like everyone else. So, we were forced to concentrate on conserving our cash to weather through — not knowing how long it would be until things got better. We survived, and eventually did go public. Here are the lessons we learned from the trials of 2001, I think they will be as useful in today’s downturn… Read More about I survived 2001, and even IPO’d! Lessons for weathering a downturn.
