Linksys, Dovado & Netgear all have PCMCIA slot versions of their WiFi 
WAN routers. These work now today with 3G/HSDPA and with PCMCIA card in 
Finland/Slovakia.

The OpenWRT can be customised once we figure out Linux driver and runs 
on all 3 of these boxes. The manufacturers will be releasing Irish 
Network OFDMA firmware. The Slovak folks are working on F-OFDM driver 
for OpenWRT already.

USB only works in Finland/Slovakia. USB/PCMCIA/PCexpress 3rd gen before 
end 2007.

At the minute only PCMCIA (cardbus 3.3V).

Today the only driver I see working is XP. At public launch there will 
be XP, Vista, OS X. The retail CD has Redhad Enterprise kernel 2.6.9 
binary ready to run and its full MPL/GPL source

I'm assured the linux driver works, but I have not access to that 
flavour of Linux.

Maybe with people here we can get CentOS, Ubuntu, Fedora etc 2.6.20 
working and also Elf3 PCMCIA handheld PC (2.4 kernel).

I've spent about 2 weeks and not got the supplied source to compile. 
I've successfully compiled the Slovak 2.6.20 kernel source on Fedora 
Core6 and Fiesty Fawn Ubuntu and tried it with the working Irish 
ft2000.img (DSP file) and QFT supplied and Slovak ft1000.conf in /etc/pcmcia

Yes. But I'm not allowed to say. It's mostly not distinguishable from 
using DSL or  Metro.  Obviously you  get less  speed  on any wireless 
system as users are added. The quoted 3 speed is for one user only in a 
sector with view of mast and wind behind :) I think 3G is max about 25 
users and then 26th dialup fails.  The 4G OFDMA supports 1 to 127 
streams and <50ms  from "sleep"  to  upload/download . I think the limit 
of   Static IPs  of sleeping modems in a 4G OFDMA cell is possibly the 
entire subnet. There is no dialup.

I'm 6km from Raheen. I don't know when a Limerick base will be live. But 
there definitely will be one with up to 25km radius  possibly or more on 
fixed external Yagi.

The range on the built in aerial seems good. I'm unfortunately not at 
liberty right now to say what that range is. But you won't be disappointed.

Not really. The 3G/HSDPA technology actually  maxs out about 70k for 3G 
and only a little more for HSDPA.  Who knows when  O2/Voda/3 will deploy 
HSUPA which allows higher upload speeds. *

No. Digiweb is primarily a ISP providing a DATA NETWORK. They are NOT a 
phone operator!

The only thing Digiweb blocks and will block on 4G is Port 135 .. Port 
139 to protect people who don't know to remove MS Bindings to NIC and 
other Windows issues. They will even remove that blocking on your IP if 
you convince them you need it and understand what you are doing!

Metro has real phones and SIP built in. Neither Skype nor any 3rd party 
VOIP/SIP (Smart 076, Blueface etc) is blocked or shaped. Of course only 
Metro built in SIP and 4G Digiweb SIP will have managed QOS direct on 
Digiweb's private network to Digiweb's Gateway, altogether better than 
3rd party VOIP across random Internet Routing.

Every Internet protocol and port can be routed on Digiweb Metro & 4G. 
There may be some eircom imposed restrictions on DSL Bitstream, I don't 
know. I don't think Digiweb FWALA wireless has any restrictions.

Not really. In terms of speed, cap, contention, price Metro is better 
but fixed. 4G is mobile, though cheaper than dialup as a fixed solution 
and can do longer distances with a outdoor yagi.

I can't publicly  comment on that, except that if you cancel eircom 
line, the 2way sat can be cheaper than dialup but near 700ms ping. Watch 
for new product announcements.
