The Quest for Wireless Gigabit:
Recent Advances in the Wireless Physical Layer
Brandon Heller
Abstract:
A number of recent advances in the physical layer are enabling wireless communications devices to reach ever-greater speeds. These developments in modulation techniques, coding, and radio architecture enable better spectrum allocation, more power-efficient, error-resistant transmissions, and more flexible architectures for receiving signals. Many of the advances are being included in upcoming standards, like 802.16 and 802.11n, and will likely improve the already-fast adoption of wireless networking equipment.
