Hi People,
Have been experimenting with the "hamserv" AX25/tcpip BBS system Written
by Ken williams G3TMH.
This system allows smtp/pop3/http/nntp & telnet access to both ax25 packet
mail and internet mail, depending on how it is configured.
I have been running a mail server that is available from the
www.gb7abc.net web site, along hamserv and other software that allows mail
recieved from winpack to be transfered to hamserv's nntp queue for access
by people on a tcpip system, such as the 2.4 Ghz wlan system I have been
experimenting with. Although only simple, the system has allowed my
network partner, vk3yy, to use outlook express to access this
winpack>>>hamserv mail over our wireless lan system.
The mail, that took me 20 to 30 minutes to get via 1200 baud ax25 was
transfered to glenn's system in only a few seconds!!!!!
The plan, eventually, for the wireless lan system is to utilsie the normal
ax25 bbs software, like hamserv and fbb and have 2.4 GHz uses, select
their mode of entry to the bbs's for mail, FBB will do telnet and can act
as a gateway between hamserv and the user or then could use winpack's
ability to telnet to fbb and transfer mail directly to an interface that
they are already used to using.
Anyway, just a few more happenings.
Hopefully, we will have another amateur locally on the network within the
next few days. Both Glenn (vk3yy) and myself have set up dishes in his
direction so as he can establish a path to either or both of us to test
his system.
It is quite apparent to both glenn and myself from what we have
experienced that one must not give up too quickly with setting up a
wireless lan to cover a large distance. When we first started testing some
months ago we could only manage a sniff of a beacon here of a hint of a
beacon there, then to the odd ping every now and again to a 1 Mbuit/s link
for a short time. Now with the refining of our antennae and coax runs, we
have estabilshed a link that is in the low -80 dbm range which is good
enough for 11 Mbit/s and a guarrantee of 2 or 5.5 Mbit/s.
Currently, glenn has 100mW of power situated at the base of his dish with
about 2 m of ldf-450 coax. Power is supplied over the ethernet cable (PoE)
to his host PC. My system consists of 89mW (dont ask me why the
manufacture could not round it off??????) with a 6m run of LDF-550 coax
and a 2m run of flexiable FSJ-50 (??) coax into the shack with teh AP
mounted onto on the bench linked via ethernet cable to my hub where I can
use any number of PC in my home network to access the link. Plans are to
move my AP to the back of the dish but first a suitable sealed enclosue
and manufacture of PoE devices are needed. It should bring up received
signal strenght indications RSSI to high to mid -70 dbm's which would more
or less guarrantee our 11 Mbit/s speed.
As more and more local people wish to get involved, the need to establish
a central repeater/AP/bridge-to-multipoint-bridge system will become
paramount and we are always on the look out for a suitable high sited low
interference level position.............
Regards
Mark
