Networks using lower frequency spectrum tend to fare better in rural areas as their signals propagate better, especially in hilly areas.
In an announcement of sorts yesterday, DARPA reportedly said that the project's goal is to use "set of handheld devices" to track down a specific "signal emitter of interest" using radio frequency geolocation, and presumably some other measures they're not about to dish the details on.

The slower signals are sent using a different antenna using the same frequency channel.
McDonald was also the third physician in the world to perform a procedure called conductive keratoplasty -- a noninvasive surgery for farsightedness that involves using radio-frequency energy to heat small spots around the cornea.
High frequency traders, using powerful computers to trade in nanoseconds in high volume, are courted by exchanges because volume equals profits.
With HackRF in the hands of hackers or security researchers, in other words, no wireless signal would remain secure just by virtue of using a unique, unfamiliar frequency.

O'Donoghue's victory was marred when he received a two-day ban (27 and 28 May) for using his whip with excessive frequency and not giving his mount time to respond.
The engineers found a way to kick-start a radio-frequency device wirelessly using an external power source initially, but running the device afterward on the output of power generated by the inner ear.
The ticket systems and frequency of the trains using the line, also needed to be improved, he added.
That conundrum was solved by getting the high-frequency signals to penetrate deeper using alternating waves of electric and magnetic fields.

The BLPC predicts power consumption of bit lines by using replicated bit lines to monitor the frequency of the ring oscillator.

They ranked the locations based on frequency of positive and negative words using the Mechanical Turk Language Assessment word list.
The Swiss Federal Railways has improved efficiency in recent years too, by using double-decker trains and increasing its trip frequency.
Their basic concept is to use light to transmit the quantum information using interferometers, which are instruments that change the frequency of light waves, then recombine them to get particular effects.

Things smaller than the wavelength of the beam you are using will not show up, so increasing the frequency (ie, reducing the wavelength) means that finer details can be picked out.
Belly has found that stores that use its service have seen an increase in 20% frequency of customers coming to the business after using Belly.
There is also concern that Bluetooth devices will conflict with those using 802.11b, since the two technologies share the same frequency band.
What does Dr Paxton - who is using the Loch Ness phenomenon to analyse how science handles anecdotal and low frequency data - think?

Broadcom and Atheros say that making the interface information public would be illegal, because it could allow users to change the parameters of a chip in ways that violate the rules for using unlicensed spectrum (for example, by increasing its power or changing its operating frequency).
Using millimeter wave technology, which the TSA says emits 10, 000 times less radio frequency than a cell phone, the machine scans a traveler and a robotic image is generated that allows security personnel to detect potential threats -- and, some fear, more -- beneath a person's clothes.
