Configuring a point to multi point as a technology for me, arises as the need for more people to use devices to connect to the internet. Assuming in a community of a million persons having at least one or two mobile devices, computers and gadgets which they will definitely connect to the internet, putting up a point to point link will be like construing masks and putting up communication equipment and radios every inch of the community, and this will be very awful for any one to do this. Hence the need for a point to multi point arises.The data communication companies also employs this technology of configuring a broadcasting radio as an access point so that where ever a user is, as long as the user is on a line of sight, connection is made automatically without waiting for point to point dedicated link. A point to multi point link can go as far as 7-12 Miles on a straight line of sight depending on the data communication infrastructure use to establish the connection.
Point to Multi point links is widely used when central location needs to be accessed via several nodes. Although It is a more complicated version of Point to Point link. Hence in other to make it stable and successful several steps have to be taken into account when creating such links. Nodes (CPE) are at various locations; therefore ACK parameter should also be taken into consideration during the configuration.
Even though some data communication companies has refuse to embrace this technology, maybe due to what I might call their inability to successfully manage such links or reason best known to them. I see it as wast of resources, if you can, and refuse especially when your located within a range of 7- 12 miles to the service provider. Meanwhile you can have access to transmit using a frequency that no one else or two persons could be using around you. if your using unlicensed radio offering you zero or minimal interference, high throughput, and greater signal, all depends on the configuration employed.
Having outline some basic principles of point to multi-links, lets setup this link, using a 5 GHz mikrotik out door unit.
When your setting up a point to multi point link using this mikrotik equipment, your should be aware that you will be exposed to interference because these radios operates on a free licence frequencies which means you will have so many others radios broadcasting on the same channels also.
In other to optimize and stabilize your Mikrotik wireless links and improve the throughput, we going to show you how you can use the Super channel feature on Mikrotik device to optimize your wireless links and by so doing, increase your throughput. Frequency altering and guessing is a very sensitive issue and Mikrotik has chosen frequencies available for selected countries. So using the super channel feature might constitute an offence, depending on your country of deployment.
When you’re done with the set up, next thing is to lunch your Winbox application to access your Mikrotik radio. For me I normally Log in with Mac address.
It is important that the frequency on the access point link is entered in the scan-list of the station radio; so that you will be able to see the access point radio when you scan from the station. To get the best frequency to use, you should consider entering some frequencies in the scan-list of the access point, and then click on snooper. This I do always because what it will do is to run a snoop test on the frequencies and then determine the ones with less usage around the environment. You can then select the one with less usage and enter it into the space for frequency on the access point. With this setup you will have an optimized link with less interference.
