Bandwidth & Throughput
- Bandwidth is calculation maximum amount of data that travel trough a channel.
- Throughput is the real maximum amount of data that "actually" travel through a channel successfully.
- So... bandwidth is just calculation, throughput is the real according to some parameters like interference, freznel zone, visual LOS and etc,
- Channel width is lists of wireless band. Improving channel width will make throughput increase. But it will increase interference too.
- Interference is unwanted signals that have same or almost same frequency that interrupt each other
- Data rate not indicate throughput, because data rate always change dinamically according to its environment.
- Data rate is throughput for half duplex communication.
- For full duplex communication usually half of data rate,
- Improve data rate will make power propagated increases.
- CCQ (Client Connection Quality) is persentage that shows effectiveness of bandwidth.
- Formula of CCQ is average of Tmin divide by Treal calculated every frame transmitted.
- Tmin is time to transmit data at highest rate without retries.
- Treal is time to transmit data in real condition.
- Good CCQ will get good throughput.
- Requirements for get good CCQ:
- Good Signal Strenght
- High SNR
- Ideal Freznel Zone
- Free interference
- Access list is used for authenticate which station that permit to connect AP.
- Connect list is used station to athenticate whice AP that want to connected.
- Default forwarding:yes means client can send traffic to another clients in same APs area.
- Default authenticate:yes means all client that not limited by access list will authenticated and connected.
- CAPsMAN is feature in Mikrotik that allow wireless centralization. It means you can configure many AP via controller. Controller is called CAPsMAN and AP that controlled is called CAP.
- Station Mode
- station : most simple client mode
- station-wds : activate WDS bridge
- station-pseudobridge : includes MAC translation so wireless interface can join in bridge
- station-pseudobridge-clone : use station-bridgeclone-mac address function
- AP Mode
- ap-bridge : standard for Access Point
- bridge : same with ap-bridge but just receive one client
- wds-slave : ap-bridge mode have ability to scan AP with same SSID and built WDS link to that AP. If AP disconnect, it will re-scanning and will connect again
- Special Modes
- alignment-only : activate align transmit mode that used to antenna pointing
- nstreme-dual-slave : its used for dual-nstreme
