Link
High-speed wireless systems are
used to provide internet access to
end-users using point-to-point or
point-to-multipoint architecture.
Wireless data links take place where
there is no infrastructure for internet
access or in places where bandwidth
offered by current channels is too
low. With our wireless equipment you
can get high bandwidth on a very long
distances at very reasonable price.
Our equipment provides various features
including firewall, NAT, VPN, Bandwidth
Management, QoS and many more.
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
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. |

Point-to-point links
PtP links are an excellent way how
to make connections between two sites
and achieve high data transfer speeds.
This is an ideal way how to connect
two offices. Also these type of wireless
links are very useful if you need
to create backbone link from some
distant radio access point to your
main Internet source. For creating
such connections we recommend to use
our 5 GHz and 2.4 GHz wireless client
kits.
A customer
from Bulgaria reports:
"This 35Mbit at 57km is with non-turbo
mode, unidirectional, with random-data=no.
Machines on both ends are 700MHz C3.
During the test, both routers (that
have few more Atheros interfaces each),
were not transporting traffic." |

Point-to-multipoint setup
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. |

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.

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.
A customer from Bulgaria reports:
"65 km, AR5213, 37 Mbit with
n-streme (TCP test), We're using 2.4
GHz proccesors or better, 5GHz-turbo
mode"
To make this setup, you can use:
Two PCs with Celeron 700 or higher
Four Atheros PCI wireless cards with
pigtails
Four antennas
Two IDE flash disks with latest version
of RouterOS software. |

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.
