PtM connections are the most usual way how wireless ISPs connect their customers. They put access point somewhere high in the tower above the city or on some high building and then point their client antennas to this access point.
This is a point to multi-point link with additional wireless cards and antenna for a backbone connection. Such links are useful when creating a WISP infrastructure, for example you have main Internet source with 5 GHz base station and lots of 2.4 GHz clients in various sides of the city. Such kits can be but in localized parts of the city and contain 2.4 GHz omnidirectional antenna and 5 GHz directional antenna to main base station.
These are MikroTik proprietary wireless protocols to achieve outstanding performance on a very long range links. Regular wireless links will have large time delays for data traveling on a long distances, with nstreme you do not have to worry about this anymore.
Nstreme 2 goes even further by using two wireless cards in each end - one for transmit and one for receive.
Our customers have links of 60 km and speed of 35 Mbps without turbo mode.
