iskash point-to-point ili multipoint
reshenie.

ne.
za 1-wiq w powecheto sluchai dostawchicite predpochitat da instalirat
multipoint za da ne kupuwat nowo ustrojstwo ot tqhnata strana za wseki

za 2-riq ako e multipoint trqbwa da e 802.11b syvmestimo, ima mnogo
prichini za towa.
a ako ne e multipoint moje da e kakwato si iska jylta marka na kakwato

ogromniq overhead ot wsqkakwi podpomagashti predawaneto po shared
mediata (efir) ostawat okolo 7. Az poweche ot 6mbps ne sym wijdal.
