Originally posted by RonHendriks1966 Well it needs to be much faster then the transferrate for Eye-Fi to be a real workable tool I think.
Roughly 2MB/sec which is also approximately the same speed as the Eye-Fi.
It's one 802.11n transfer channel (802.11n can do two) bottlenecked by the SD memory speed (at least the Eye-Fi was bottlenecked by that).
The Eye-Fi creator (he was answering questions on model mayhem) said the limit was around 17Mbit/sec which is roughly 2MB/sec.
Transfer smallest JPEG (6MP?)....that's the only way you'll get an acceptable experience.
Even then, the code on the card has to do roughly this:
- do I have stuff to transfer?
- is wifi connected?
- bring up server so others can connect to me
- if memory is not busy (you're not doing image preview or taking photos), do transfer
So the theoretical 2sec for that 4MB file turns into 5sec or more...
