This is really interesting information. I didn't know a lot of this, and
do get asked this a lot. Thanks to everyone who has posted.

Hi Ratko,

it depends a lot on your coverage requirements, as well as on the number
of endpoints you need to support.

If it's more than a few phones and more then what could be covered by a
couple base stations, the price of Polycom (ex-KIRK) DECT systems
becomes quite competitive. (ie. covering large areas with "traditional"
systems isn't exactly cheap eiteher).

Nominal coverage area for DECT systems is around 30-50m indoors and
100-300m outdoors, if I recall correctly, but this rarely translates
well in reality as it depend heavily on the environment. Anyway,
usually, the coverage is much better than that of standard 802.11
wireless and it should be determined by a site survey before a purchase
decision is made. 

There are several configurations for KIRK systems:

600v3 - this is an all-around system, as it can work in 

single cell mode: one active "server" and up to 6 repeaters - only the
server needs ethernet connection, the repeaters only need wireless
signal and AC power

or multi-cell mode, where more 600v3 units can cover a larger area, or
you can build coverage islands (this is one killer feature, a
"traditional" system might not be able to counter, especially if you can
use existing ethernet cabling to add new "islands" to the network). 

Unless you have a very large system, all "Kirk Wireless servers" act as
base stations (will have active radios in them)

600v3 can do SCCP as well (phones will appear as  Cisco7940 on the
CallManager)

Each 600v3 base station can support up to 12 simultaneous voice channels
(this is a LOT more than most "traditional" systems will do - that are
more close to 4 or the like).

the 6000 is a newer system, where you'll always need a "server", that,
although comes in a wall-mountable box like the 600v3 has no radio in
it. You can add "base stations" to it, that are the same size as
repeaters (10x10cm, if I recall correcty) but are PoE powered and
connect to the Ethernet network.

Wile it's been a while I've worked with them, but I think above 4-5 base
stations the 6000 system starts to be cheaper than the 600v3 (with the
same number of BS-s).

The 6000 is SIP only. Also it has an even larger scalability than the
600v3, although channels per base station is somewhat lower.

In Multicell 600v3, or 6000 systems, each base station can support up to
3 repeaters.

Also: You can connect almost any DECT handset to both Polycom Kirk
systems. Any handsets that you can choose which base station to connect
to (on some DECTs designed for home use only this isn't possible I
believe, as they are hardcoded for their own base station).

Regards,

  Zoltan Kelemen

Thanks for your replay, as I understand, I need KIRK wireless server,
wireless base station, several repeaters and the number of phones...
Is't this to much? What is the coverage of a station? I know the
phones a pretty expensive too.

Regards
Ratko
