Sierra Wireless MC8781


Recommended Posts

You are right:

Those two have receive equalizer with dual antenna diversity.

- MC8780: 850/2100 MHZ optimized for Europe and Asia Pacific

- MC8781: 850/1900 MHZ optimized for North America

And this card supports tri-band UMTS/HSPA so in MC8781 case I think it prioritize UMTS/HSPA usage - cause between GPRS and UMTS it expects EDGE and cause of US optimization in europe it doesn't detect any so it pushes it to higher frequency. That is why I have observed higher speeds on this modem or this is another placebo effect ;)

I'll soon get my hands on MC8775 so I'll have a comparison.

My friend just bought Sierra Wireless MC8775 for his WinXP thinkpad. I had 30 minutes to check it against my E6400 Lion and I'm happy to report that it works! I had issues connecting by AirCard Watcher that I use for MC8781 but I guess this can be easily fixed by using other one (for 875U).

Well, the one thing I know: it is NOT in USB mode. There is no USB storage or partition to be seen. At least in Finder, PathFinder and Disk Utility.



Is this out of your System Information or have you used any kind of a tool to extract this info?
