The figure below shows the Intranet of a company and two connected remote branch offices. Office A is connected to the main company Intranet via a geostationary earth orbit (GEO) satellite link. The satellite link has a high data rate of 1 Gbit/s, but also a high propagation delay of 250ms. Inside office A, stations are connected to a wireless access point based on IEEE 802.11b with 11 Mbit/s. The wireless stations can be considered stationary and are placed within a quadratic area of 400m square around the access point. For the connection of office B, the company has leased a fixed line with a data rate of 2048 kbit/s (see parameter sheet for delay of the link).
