Also these types of wireless links are very useful if you need to create backbone link from some distant radio access point to your main Internet source. Point to Multipoint PTM connections are primarily used by 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. Point to multipoint Why choose Mikrotik? Cost effective solution High-speed wireless data links (Up to 108Mbps) Connection distance up to 70 km without repeater sites IP - NAT, Routing, DHCP Security - Firewall, Secure Tunnels Control - Queues, Proxy, Accounting, HotSpot Fast and simple installation for base station and clients Reliable and instant 24 hour internet access Backbone link + AP 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.

Backbone link Basic requirements to create a wireless links are: Direct Line of sight between both points of presence Distance between points of presence is: up to 25 km for point-to-multipoint links up to 70 km for point-to-point links Use of 2.4 or 5.2-5.8 GHz solutions according to the local regulations. 

In some countries obtaining a special license might be required. Our wireless systems come with Mikrotik RouterOS software preinstalled. RouterOS will enable you to use many features such as: firewall, NAT, bandwidth management, different kinds of tunnels, HotSpot and others. Nstreme and Nstreme2 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. Nstreme WDS WDS (Wireless Distribution System) is the best way how to interconnect many access points and allow users to move around without getting disconnected from network. 

Using this system you can cover large areas and allow users to move for large distances while still being on-line. This system allows packets to pass from one wireless AP (Access Point) to another, just as if the APs were ports on a wired Ethernet switch. APs must use the same standard (802.11a, 802.11b or 802.11g) and work on the same frequencies in order to connect to each other.
