	NEW 5.8 GHz cordless phones: are they better than 2.4 GHz? (Site not responding. Last check: 2007-09-05)
		When a system is employed in a confined space such as an office or home, many obstacles such as office equipment, walls, and doors obstruct the handset-to-base path and prevent signals from circumnavigating barriers like they could in a less densely occupied area.
		The primary benefit of 5.8 GHz models is the avoidance of interference with 802.11b wLANs and microwaves.
		In addition to their other advantages, the 2.4 GHz and 5.8 GHz frequency bands are above the range that most scanners can intercept, making it much more difficult for eavesdroppers to listen to your conversations.

	Deployment Information - White Papers - The Benefits of 60 GHz Unlicensed Wireless Communications (Site not responding. Last check: 2007-09-05)
		The 57-64 GHz band is located in the millimeter-wave portion of the electromagnetic spectrum, where the wavelength varies from ten millimeters (30 GHz) down to one millimeter (300 GHz).
		Point-to-point wireless systems operating at 60 GHz have been used for many years by the intelligence community for high security communications and by the military for satellite-to-satellite communications.
		The wedges for 2.4 and 24 GHz links are substantially larger than the 60 GHz link, even though their operational link distance is the same (1 km).

	gigahertz - a Whatis.com definition - see also: GHz
		The gigahertz, abbreviated GHz, is a unit of alternating current (AC) or electromagnetic (EM) wave frequency equal to one thousand million hertz (1,000,000,000 Hz).
		An EM signal having a frequency of 1 GHz has a wavelength of 300 millimeters, or a little less than a foot.
		An EM signal of 100 GHz has a wavelength of 3 millimeters, which is roughly 1/8 of an inch.

	An Introduction to 10 GHz Wideband Operating in Ontario
		The 10 GHz band (10.0-10.5 GHz or 10000-10500 MHz) is one of the easiest microwave bands to get on, primarily as a result of its proximity to frequencies heavily used by various types of radars and the resulting equipment availability.
		Most 10 GHz FM operation is by portable stations who normally use some sort of tripod to support the antenna and at least some part of the electronic part of their equipment.
		It tends to be difficult to make good use of them for 10 GHz wideband FM because they usually happen at night and early in the morning, at which time you need to arrange with another ham to go to portable sites, probably more than 100 km apart to try for a contact.

	GHz
		When referring to a computer processor or CPU, GHz is a clock frequency also known as a clock rate or clock speed representing a cycle of time.
		A oscillator circuit supplies a small amount of electricity to a crystal each second that is measured in MHz or GHz, where "Hz" is the abbreviation of Hertz, "M" representing Mega or one million and "G" representing Giga or one thousand million.
		In addition to GHz and MHz there is KHz or 1,000 Hz.

	Sharky Extreme - '+$ArtG+' - '+$ArtC+' - '+$ArtN+'
		For the first time in a long while, the Duron was also on the defensive (at least in terms pure core speed) and this rapid speed jump for the Celeron caught a lot of people by surprise.
		It is also interesting to note that AMD not only introduced their enhanced core with the Duron 1 GHz, but that the Duron 1.1 GHz was the follow-up.
		Exactly how fast the Duron 1.1 GHz really is a more important question, since as we have found out from the Pentium 4, a higher core speed may not always get you the performance crown.

		The 7 GHz models cover from 5.9 to 8.5 GHz with 19 dBi gain; the 13 GHz Megahorns provide 20 dBi of gain from 12.7 to 13.2 GHz; and the 14GHz models cover from 14.5 to 15.35 with 20 dBi gain.
		Alternatively, the 2 GHz antenna can be ordered with a mounting plate and a standard "N" connector for the RF signal.
		In this configuration, the 7 and 13 GHz Megahorn antennas are supported by a lightweight mounting bracket on a medium weight tripod.

	AMD Bridging the GHz Divide - MegaGames pc
		Performance based ratings or not AMD are beginning to realize that they are falling far behind their rivals in processor clock speed.
		Whether PR ratings are an accurate representation of what a processor will do for you or not AMD cannot be seen to fall so far behind Intel since they too were involved in the GHz wars and seemed to enjoy the attention that they received when they reached the 1GHz mark first.
		Based on the curerent GHz to PR rating ratio, it is expected that the 2400+ will clock at 2.06 GHz while the 2600+ at 2.2 GHz.

		The performance of the dual G4 1 GHz and the single 933 with Photoshop was almost identical--identically fast, granted, but it would have been nice to see a big difference between the two.
		Beginning with the same image, I converted the background to a layer, applied bevel and emboss and satin, rotated the canvas 360 degrees in 90 degree increments and then performed a horizontal and vertical flip of the layer.
		Action 4 consisted of converting the background to a layer, resizing the canvas 500 percent, rotations and flips as in the previous test, scaling the layer 64.7 percent and then trimming the layer.

	Slowest Athlon 64 humbles fastest P4 in gaming
		This new model runs at the same 2 GHz frequency as the flagship product, but does so with 512 KB of level two cache, which is half of what the 3200+ model has.
		For those who need superior gaming performance than a 3.2 GHz P4, but at less cost, these benchmarks indicate that the Athlon 64 3000+ is the way to go.
		It was a smart move on AMD's part to release this device at the same frequency as its sibling, but with half the level two cache, as it still betters the P4 in the very important world of gaming.

	Intel Pentium 4 3.4 GHz - Prescott and Northwood - hardCOREware.net
		The Northwood version of the 3.4 GHz has actually been available for a while; we even used it in a recent video card review.
		Interestingly, the new 3.4 GHz Prescott features the exact same Thermal Design Power spec as the 3.2, and thus should be no hotter or cooler than the 3.2 GHz version.
		We compared the new 3.4 GHz Prescott and Northwood to the entire Hyper-Threading lineup of P4 CPU's, and of course threw in the Athlon64 3400+.

	PCWorld.com - Intel's Pentium 4 to Top Out at 3.8 GHz
		Several processors running at 3.8 GHz and slower will receive the extra memory, which improves performance by permitting the chip to store larger amounts of frequently accessed data close to the processor.
		Single-core chips running at 4 GHz or faster might eventually surface for low-cost PCs, says Nathan Brookwood, principal analyst with Insight 64 in Saratoga, California.
		Even if Intel made no changes to the current Pentium M design to improve power consumption on Yonah, which is unlikely, a dual-core Pentium M running at around 2 GHz would consume about 40 watts of power.

		While the top of the line 3.06 GHz Pentium 4 is far too expensive for most hardware enthusiasts, it is one of the most anticipated Intel processors ever.
		Simply put, the goal is to maximize execution resources by executing instruction streams from multiple threads simultaneously, thereby exploiting parallelism at the thread-level rather than just the instruction-level.
		Tests with the first revisions of the 2.4 GHz Pentium 4 Xeon revealed that HyperThreading could push performance in server applications about 0-30% higher, and workstation applications typically get a -10 to +20% boost.

		First of all, there's just not much to talk about here beyond a 200 Mhz bump in CPU speed. Secondly, by all indications, this is the end of the line for the highly acclaimed 0.13 micron Northwood Pentium 4.
		While the 3.20 is perfectly stable at the high temperatures it reaches with stock cooling (expect to see it in the mid-60's Celsius after a while of gaming), many people looking for a silent or quiet computing experience will have to look elsewhere.
		Prescott should show up sometime this fall, also at 3.20 Ghz, and it won't be a moment too soon.
