The design work of Group of Seven painter J.E.H. MacDonald was not only central to his personal artistic development, but inseparable from the graphic design industry in Toronto from the 1890s to the 1930s: the "golden age" of book and magazine illustration. This connection has been largely overshadowed by his painting. Now this splendid book, tracing MacDonald''s involvement with fine printing, book design and commercial art, raises the profile of graphic design as a formative influence in Canadian visual culture.

If you've been searching for a way to get up to speed on IEEE 802.11n and 802.11ac WLAN standards without having to wade through the entire specification, then look no further. This comprehensive overview describes the underlying principles, implementation details and key enhancing features of 802.11n and 802.11ac. For many of these features the authors outline the motivation and history behind their adoption into the standard. A detailed discussion of key throughput, robustness, and reliability enhancing features (such as MIMO, multi-user MIMO, 40/80/160 MHz channels, transmit beamforming and packet aggregation) is given, plus clear summaries of issues surrounding legacy interoperability and coexistence. Now updated and significantly revised, this 2nd edition contains new material on 802.11ac throughput, including revised chapters on MAC and interoperability, plus new chapters on 802.11ac PHY and multi-user MIMO. An ideal reference for designers of WLAN equipment, network managers, and researchers in the field of wireless communications.
