as you certainly know, LTE (4G = Long Term Evolution) is the latest
radio communication technology coming in many countries now. It
is designed to provide VDSL like data rates over the air.
Now, since we have the same Qualcomm chipset in our OPTION
GTM601W as the iPhone 4 has, I played a little with the AT commands
this morning and found this command:
gta04:~# ./femtocom /dev/ttyHS_Application
Manufacturer: Option N.V.
Revision: 220.127.116.11 (Date: Jan 5 2011, Time: 11:14:34)
As you can see, ATLTE is accepted and takes a parameter 0 or 1,
while ATLET is rejected.
After issueing this command I had the impression that some http pages
are loaded at much faster speed than with 3.5G (UMTS).
Unfortunately the command is not described in
nor anywhere else. So we have to experiment ourselves.
