High Performance WIFI link: Unterschied zwischen den Versionen

Version vom 3. Mai 2009, 22:05 Uhr

1 Project goals

This is the master project of all these WIFI link projects. All the other projects only served for acquiring according knowledge, but this time, we'll do the real thing: Set up a link over 30 kilometers. Since we intend to connect DB0MHB with a high performance link to the AMPR Amateur Packet Radio network, we want to hook MHB to the Deutsches Forschungsnetz over the Fachhochschule Regensburg.

This project must be seen in the context of the southern German initiatives such as that of DARC district Oberbayern to extend the Austrian HAMNET into Germany. District Oberbayern has decided to spend some thousands of euros for buying the necessary hardware to establish a number of high speed links, using exactly the same hardware platform as we're doing. Lest, we're not extending the network from south to north, but we're establishing one single link from north to south. But we clearly support the idea that our networks are growing together, which will require some more investments by other carriers.

Precursors of this project are these projects:

• Setting up a WIFI link between DL8RDS and DB0MHB
• Turn a Fonera router into a link station

2 Hardware

We have the same hardware on both sides:

• 1 meter diameter parabolic dish from Ebay
• Mikrotik RouterBoard 433
• WLM54SAG MiniPCI WLAN Interface
• R5H Mikrotik HighPower WLAN interface
• Custom Frequency License to transmit within the Amateur Radio bands

Cost estimate:

• dishes 60 Euro
• Router hardware 430 Euro
• several working hours

3 Software
