IEEE MIMO-Assisted MPR-Aware MAC Design for Asynchronous WLANs
The use of multiple-packet reception (MPR) in wireless networks is known to improve throughput especially in high-traffic conditions. The lack of synchronization among the nodes in random access systems introduces significant challenges toward the adoption of MPR in the PHY and the MAC design for systems using MPR. In this paper, we propose an asynchronous MPR method for the PHY and also design a compatible random access MAC for wireless local area networks (WLANs). Relying on space-time coding techniques,...

InfoWorld Broadcom to unveil four chips for faster '5G Wi-Fi'
The International Consumer Electronics Show next week may be a major launchpad for a new, faster generation of Wi-Fi that goes about three times faster than current gear, with at least one major silicon vendor announcing and demonstrating a set of chips for the IEEE 802.11ac standard. Broadcom is announcing the four chips for PCs and consumer electronics products on Thursday, a few days ahead of the massive trade show that formally opens next Tuesday, and said it is already shipping the...
InfoWorld Coming next year: 802.11ac for faster Wi-Fi
Gigabit-speed wireless LAN products based on the emerging IEEE 802.11ac standard will start shipping next year and usher Wi-Fi into its next era of high speed and long range, communications chip maker Broadcom said Thursday.
InfoWorld MediaTek lays groundwork for gigabit WLANs
Semiconductor company MediaTek has introduced a system-on-a-chip (SoC) that will be used to power wireless routers based on the 802.11ac wireless networking standard, which promises gigabit speeds, the company said on Monday. The upcoming 802.11ac standard will offer higher speeds than what is currently possible using 802.11n thanks to the use of more spectrum and more advanced antenna technology.
InfoWorld Aruba to buy Avenda for BYOD security
Wi-Fi infrastructure vendor Aruba Networks will buy Avenda Systems to expand its network security offerings and help enable BYOD (bring-your-own-device) strategies in enterprises. Aruba announced the deal on Thursday as it reported financial results for its first fiscal quarter ended Oct. 31. Pending regulatory approvals, Aruba expects the acquisition to close during the second quarter of its 2012 fiscal year, which ends Jan. 31.
