I don't understand your question in the context of LoadRunner. Perhaps you chose the wrong forum?
LoadRunner would emulate a browser just fine, including mimicking different connection speeds. If you want to do other types of testing, like functional, other tools would be needed.
Try running a search (upper right of this page) and see what pops up, or look in the Web Testing forum for relevant topics.
Resistance is futile.
Which testing tools are useful for Browser Emulation ?
