Category Archives: WAN Emulation

WAN Emulation is the simulation of a WAN (or GPRS, 3G, ADSL, DSL, Satellite, Radio etc) network in such a way that you can plug in real devices (clients, servers, switches, routers) into the emulated network to test how an application will perform over the emulated network.

It’s Worse than that Jim – Bandwidth is not equal to Link Speed either.

So how fast is Mobile Broadband (3G) really

Posted on January 20, 2009 by Frank Puranik

Recently, I got myself a 3G “dongle” so I could connect my laptop and be on the Internet anywhere at a “reasonable” speed. If you haven’t re-visited these gadgets recently you might not have noticed that they’re up from the … Continue reading →

Are You Testing in Realistic Network Environments?

Posted on January 5, 2009 by Frank Puranik

Happy New Year! Just before Christmas we exhibited at the TestExpo show, which specialises in tools for testing software. Chatting with the testers and developers during the show I’m still amazed that when testing, and during the development process itself, … Continue reading →
