DJT in ! And blatently disregards federal law and wipes an email server in the middle of an investigation…. Maybe that could pay off? The real conspiracy is that these towers are put up by government, sometimes in the form of LEO with stingray, but also actual full scale towers, in order to spy on citizens and visitors. One well known sign you have been logged on to one of these spying towers is a degraded signal to 3G. Another sign is that you are on federal property, where this seems most common.
It is known once you are paired with a tower in this way, your phone is essentially open for automated data collection — but they really want your contact list, call history, location history.. Well heck, they apparently take it all.
I think I;ve been doing to much radio work. Seems to me that she should be immune to mind control, because it appears she has no mind to control. Woodpeckers were famous for making nests in the feedhorns of our C-Band and Ku-Band satellite uplinks. So this silly animals did not know, that they would taste much better properly fried than just microwaved? Seem them, tried them. They still loose effectiveness after a while. Of course, as a ham I may be a bit biased when it comes to antennas.
Good point. They can effectively be dislodged with explosives. Sadly, archaic federal and state regulations prohibit this. Yup, I disagree completely. Your rights to have a pretty back yard end at your property line.
No need to stare at them raiding ones blood pressure, an eyesore is more preferable to a constant odor or noise that there is no escape from. Of course citizens resist. You think they put these in expensive hoods? You are complaining about people trying to maintain their very average property values. So, in your sick view of humanity, having money and using it to create jobs is somehow evil?
Are they evil too? Or do they get a pass because they sign your paycheck? Property values are a myth. Your property rights end at your property line. You have no right to dictate what happens beyond that line unless it poses a safety or health risk to the entire community. Antennas do neither. Get over yourself already. The most ridiculous one in this area is there is a section of Highway 18 in the angeles mountains that was hit by a forest fire some years ago, clearing the entire area of pine trees.
Or are you just saying that no one knew it was there until it survived the fire? They have no cogent point. They only have vapid indignation — like disliking the color of the emperors coat. They didnt even condemn the appearance of the antenna itself so much as make a nonsensical tirade! Then, most every attempt is made to conceal the site, visually at least. Just last month I watched a neighborhood near me show up at city hall with torches and pitch forks when they town announced it had already been working with a tower company for 2 years to install a Verizon tower at the edge of a secluded wooded park near the neighborhood.
I live in Brownbackastan KANSAS Those complaining most about visual aesthetics and their affects on property value most likely vote republican an think of themselves as conservatives. On I10 in Southern California, most of the cell towers are disguised as palm trees.. Many are pines, redwoods and such.
The problem with the flagpoles is their RF footprint. Having the antennas inside of the tower makes the distance and distance of the signal degrade. Not the case on a regular monopole, lattice or guy wire tower. The most hidden cell tower I have ever seen was inside an bell tower, the cell company removed the metal stairs, shaved the bricks to reduce attenuation. This has become a significant source of income for some inner city churches facing shrinking congregations.
I lived in a very pro-military community pretty much everyone was employed by the Navy or the plethora of companies that supported the Naval facilities in the area, so understandable. So a lot of the towers were disguised as giant mono-poles with no external equipment except for a pulley and rope to hang massive American flags on them The flags were at least 2. After a few years, you could see where the antennas were since they had plastic covers attached that discolored at a different rate than the painted metal pole.
Most cell towers also have a GPS antenna for clock discipline which is really important in getting connecting phones locked to the carrier and correcting their local TCXO drift. I love these articles. You mention that most cell sites have battery backup that will last for a couple of hours. Do they also usually have a generator to handle longer outages? It seems to me that those systems need to be able to run for as along as possible during emergencies as people rely more and more on cellular communication for everything.
This is for wireless shots for commercial broadband net fed by fiber. Previously hardened terrestrial MW relays have been or will be decommissioned leaving no redundancy. Depending on the actual fault, entire segments of the cell networks could be rendered inaccessible if not for power interruption, backhaul interruption could be just as critical.
The unspoken fact is the general public should NOT expect to have normal cell phone seric in the event of a major disaster. Government and responders get priority use of the cell phone network.
In fact the plan is to build first responder needs atop the cell phone infrastructure. Look up first net. While first net is about a broad band network, protocols for standard cell phone use have been in place for years again.
Government and first responders have priority. When the general public get access it wil be limited to time slots. The bad thing id that emergency management is telling the public this so the public cab prepare to make the best use of their time to inform distant family of their status and keep track of family within their area. Some of the early ones like those found along popular winding roads simply repeated the signal from one sector of a donor cell up and down the route. Typically, the donor site BTS was configured for 4 sectors, with the 4th sector being converted from RF to digital then distributed out to the repeaters over copper or fiber where it was converted back to RF and broadcast.
There were no provisions for pole-to-pole hand-off since each pole broadcast the exact same signal; the only hand-offs possible were either from the repeater closest to the donor BTS or the repeater furthest from the BTS to the nearest adjacent cell.
Later ones became micro cells of one or more sectors and acted like mini sites that could hand off calls from one to the next instead of simply broadcasting one signal from every location along the route. This increased the call traffic capacity on these roads since one pole only served the distance necessary to pick up or hand off a call to the next. These work more in line with what you might call a repeater, but there is channel conversion going on.
Now, when I hear DAS, I think of an antenna network in a high-rise building or such, where serving the building from external cell sites is impractical because of the size of the building or its construction. Since many antenna have a very limited vertical beam, it would take many antennae at multiple elevations to service the building from outside. DAS, in many ways, are similar to the micro cell concept: multiple sectors distributed around the building.
It also is typically carrier agnostic, though a carrier might initiate a build at a location. The equipment permits multiple carriers to share the same antenna system so whomever gets there first can lease the system to others. Her voice is a very effective human eradication mechanism. Uh, quite a bit actually. Was a broadcast engineer for roughly half of my four decade career.
Best sheild for roof tops is a layer of sidewall sllt tires to prevent water buildup covered with chain link fencing. Still gets your attention when a fifty pound hunk of ice falls feet and hits sheild. Four parameters were analyzed: microwave width , height , depth and interior space or capacity. First line for each type of microwave is imperial measurements. Standard dimensions of a microwave in inches and capacity in cubic feet. Second line is sizes in metric system.
Microwave dimensions in centimeters and capacity in liters. While exact specification not that important for countertop microwaves, over the range, build-in or microwave drawers typically made according to standard kitchen cabinets sizes. But even following standard dimensions actual measurements will depend on kitchen appliances manufacturer. Off-server Links Mike Jacobs' Coldwarcomms. Microwave Towers. Scipio, Utah.
