MikroTik Mission
We create Intel (PC) based network
solutions, because:




Hardware cost can be adjusted to the client’s
needs – contemporary or ‘server-quality’
Intel is the most powerful and most price
attractive platform
Easy hardware upgrade
RouterOS can be easily upgraded with new
functionality

MikroTik Mission (cont.)
How do we do things?:

We are a small WISP ourselves, therefore we are
able to develop solutions for our customers based on
our own experience
Our customers are:




Internet Service Providers (ISPs)
Hardware wireless ISPs – more than 45 countries
Software RouterOS – almost all countries (120+)
Organizations requiring IP network solutions for their
own needs – corporate networks (Intranets)

VPN
128bit encrypted tunnels
Applications:


Permanent tunnels between routers
PPTP Access Concentrator for many clients
(Windows workstations) and mobile clients
(work from home and while traveling)

Ethernet over IP (EoIP) Tunnels
Application:




To bridge Ethernet LANs
Can be used together with PPTP tunnels
Bandwidth can be limited over the tunnels
Providers can sell bandwidth to the corporate
customers for their Intranet needs

Can be used as IEEE 802.11b AP in
several ways:






Simple Access Point
Wireless AP and Ethernet router in one box
Wireless AP and PPPoE Access Concentrator
Can have several wireless interfaces
Can be a wireless client and an AP
Can be used to register other APs and bridge
the networks
