Great new book by Dr. Robert Jeffress, “Choosing the Extraordinary Life.” Get it and enjoy! @LouDobb

Radio signals at any frequency travel at the same speed and they all travel the same infinite distance unless something stops them. Also, the signal power received by a given antenna will fall off with the inverse square of distance and this is also independent of frequency.
At the same time however lower frequencies will tend to be received with higher signal levels and so the useful range of a system is often longer when lower radio bands are used.
This is due to a number of factors:
Normal antenna dimensions scale with wavelength and so lower bands use larger antenna leading to a larger “effective aperture”. This means that a lower band with receive more of the radiating signal than a higher band. Note however that this is not the case if you are using the same size parabolic antenna to receive for example a satellite link.
Lower bands tend to diffract better than higher bands and so they are better at delivering useful signal in behind buildings and indoors which improves coverage. This is very useful in cellular mobile systems where direct line of sight paths are often not available
Base station antenna however are often easier to build for higher bands and so more complex antenna systems may be used. This tends to mean that antenna patterns may be made more directive and so more power is directed towards the devices. This has not be a significant issue in previous generations of cellular mobile but we should expect 5G to exploit this using a technique called beam steering.
Net effect is that bands like 800 MHz will offer better coverage than say 1800 MHz. We use this to offer both longer range, and hence support wider separation between cell towers in rural areas, and to offer higher percentage of coverage in urban areas.
For this reason we tend to call bands below 1GHz “coverage bands” and higher bands whixh often have more spectrum are “capacity bands”. A good mobile network will use both types of bands.

the internet of things
everything even your dining room table will have an ip address
all the way down to your garbage, and if it was seperated properly
Hello @Sara @DarkSlayer @retiredDep just sticking my head in the door to say hi
@JonJon Hi Missed you. I was thinking about you today. Hope your doing great.❤ ☕
thanks, doing average I guess lol
nice to be missed
@JonJon Your one of the good guys. I figured you had been working a lot.
hey brutha
Newly elected Congressnurse in the 14th CD, Lauren Underwood, is under investigation by the IL State Board of Elections for illegal voting in IL and DC. Matthew Quigley is challenging her in 2020. Listen and share because it won't be in the nightly news.

@DarkSlayer well I lot of the wind went out of my sails after all the stolen electiosn etc. I just cant watch this stuff minute by minute anyore. WAY too depressing. and now the Dems gonna be grandstanding everyday? ugghhh
@JonJon The world today.
discord been frozen too. i finally had to relaod it to get in here
hell no. happy with all these crooks still riding high? nope
paaaaaatents
Woooo
🎀
@Fremp See if Dizzy wants to tell you a "funny" joke so I can kick him. LOL
