A connection node provides a high bandwidth connection on demand to mobile units that are in need of increased bandwidth for data transfers. In this manner, the connection node can supplement the bandwidth available to a mobile unit so that large volumes of data can be communicated to and from the mobile unit. A movable antenna automatically focuses its reception area on the mobile unit's location, after which, a high bandwidth connection can be established for high-speed data transfer. The high bandwidth connection is maintained, such as by tracking the mobile unit with the antenna, even if the mobile unit is moving.
