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 ABC Online?

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 unidirectional 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.
