Re: Cellphone connection - faster? Or other?


Use a UMTS / 3G internet service and openvpn
You might need a server with a real IP since all the providers in Germany I have been testing use a NAT to hide you from outside.

O2 and Fonic block SIP but they do have also interesting dayflats.
Note that on the Fonic dayflat you are limited to GPRS if you are over 1 GB per 24h. On the O2 monthly packs you are limited to GPRS if you are over 5 GB per month.

If you use a USB surf stick make sure you use an external antenna. This will make your ping times and packet loss rate much better.

PING ( 56 data bytes

64 bytes from icmp_seq=3 ttl=244 time=130.836 ms
--- ping statistics ---
4 packets transmitted, 4 packets received, 0% packet loss
round-trip min/avg/max/stddev = 130.836/133.656/141.010/4.267 ms

At night, pings are less than 100ms.

Google a bit and you will find a posting from me how to use a Huawei G3 device on NetBSD 5.

I am calling from one phone to another one,
each phone being connected to a NetBSD
system. When the call is taken, a serial
connection is established between both
computers, and with the help of slattach
that serial connection can be turned into
a TCP/IP connection.
