A group of IEEE standards for wireless personal area networks (WPANs). Following are the individual technologies. See WPAN.
802.15.1 - Bluetooth
Working with the Bluetooth SIG, the IEEE standardized the lower layers of the Bluetooth specification. Approved by the IEEE in 2002, 802.15.1 is fully compatible with Bluetooth 1.1. See Bluetooth.
802.15.2 - WPAN and WLAN Co-existence
Explores methods for interoperability between WPANs and WLANs as well as the ability to transmit in the same geographic area without interference.
802.15.3 - High Rate Systems
A WPAN standard for data rates greater than 20 Mbps.
802.15.3a - Very High Data Rate - UWB
A variety of proposals were reviewed for the ultra-wideband (UWB) standard, but the Task Group was dissolved in 2006. The IEEE's involvement helped to narrow many proposed methods into two, one of which was multiband OFDM (MB-OFDM). MB-OFDM was adopted by the WiMedia Alliance. See UWB.
802.15.4 - Low Data Rate Systems
A WPAN standard for devices that can run on batteries for months and years. Nodes can be configured as reduced function devices (RFDs), which communicate with full function devices (FFDs) only. FFDs can communicate with RFDs or FFDs. See ZigBee.

- Keeping the same revised look and feel as the recent 17-inch M17x version, the Alienware M15x is an imposing black slab of computing power that's thicker and heavier than most 17-inch laptops. We love having high-end options such as Intel's uberpowerful Core i7-920XM CPU, and it's a plus that...

- The Gateway NV5207u is what happens when a slow processor happens to an otherwise respectable budget-priced laptop. It's a good-looking notebook with a large screen, a decent port assortment, and a couple of extra features to sweeten the deal. But its AMD processor is a poor performer despite being dual...

- You can't argue with a large-screen, value-priced laptop when it delivers good performance, and looks nice to boot. We appreciated the Toshiba Satellite A505-S6960 when we reviewed it in our 2009 back-to-school retail roundup, liking its affordability, large screen, strong battery life, and excellent-sounding speakers. Just a few months later,...

- We've said it before, and we'll say it again: especially in this economy, it's hard to hate a laptop that only costs $350. It's even harder to hate a Windows 7 laptop that costs that much. The Toshiba L455-S5975 is, by 50 dollars, the least expensive notebook computer in our...

We call these 14-, 15- and 16-inch systems members of the "mainstream" category, and...

- Declaring the eMachines EZ1601-01 the best all-in-one Nettop we've seen is kind of like saying swine flu is our favorite vaccination-resistant virus.
