As much as we enjoy the convenience of mobile phones, an increasingly prominent issue is that of the dangers of cell phone towers. What are the possible health effects?
The history of cell phones goes back more than 20 years, but they were nowhere near as prevalent back then than they are today. The first mobile phones, largely manufactured by Motorola, were used by business people and other folks who absolutely had to stay connected with the office. But as the technology got more affordable, consumers started to get in on the cellular action and it just started to snowball.
In order to satisfy the needs of this growing demographic, cellular providers such as T-Mobile and Sprint had to erect more towers. Without more towers, they would not be able to offer decent reception and uninterrupted service. Early towers were only few and far between, but the number of cell “sites” has increased more than tenfold since 1994. At this alarming rate of growth, it is nearly impossible to gauge the possible dangers of cell phone towers. What was safe in 1993 may not be safe today, given the much higher level of radiation we are exposed to on a daily basis.
With this increasing need to stay connected, many of us are forgetting about the possible dangers of cell phone towers. There have been several reports of people who have suffered a variety of conditions, possibly as a result of living near cell towers.
Among the health concerns related to exposure to cell towers are:
Abnormal cell growth promotion
Reduced immune system competence
Sleeplessness, irritability, anxiety, depression
Weakened blood-brain barrier
Childhood and adult leukemia
Infertility and miscarriage
Attention span deficit and general memory loss
Sleep disturbance and chronic fatigue
And the health effects are not only restricted to humans. A study was conducted by the Institute of Pharmacology, Toxicology and Pharmacy of the Veterinary School of Hanover (Germany) which found that dairy cows were affected by their proximity to cell phone tower sites. The cows had reduced milk production and increased behavioral abnormalities. When the cows were removed from the area, the strange behavior subsided after five days but upon returning to the antenna site, the symptoms relapsed.
According to few studies, there is some evidence supporting the claim that there are significant dangers of cell phone towers, particularly affecting the health of residents in the area. If you live in a metropolitan area, there is a good chance that you are being exposed to the radiation on a continual basis and it’s hard to say for certain how significant are the effects of this exposure.
Airvana, a famous leader in small cell solutions enables mobile operators to deliver dramatically better service to subscribers in the most challenging and high-value environments. The environments include offices, public venues, and in the home. The company’s award-winning 4G LTE and 3G small cell solutions ensure “five bar” voice coverage, superior data performance, and expanded capacity for wireless services. Independent research firms consistently rank Airvana among the small cell market share leaders. Headquartered in Chelmsford, Mass., USA, Airvana is a founding member of the Small Cell Forum and has 15 years of experience providing commercial wireless equipment to over 90 operators globally.
OneCell C-RAN operates over standard Ethernet switches and cabling to deliver LTE in large venues at substantially lower cost than traditional distributed antenna systems (DAS). Nex-Tech Wireless, a mobile network operator in the west-central U.S.
The OneCell system proved itself equal to the task, delivering impressive performance statistics:
Peak 66 Mbps download speeds achieved consistently throughout the coliseum (in a 10 MHz LTE channel)
99.7% connection setup success rate
0.5% connection drop rate
100% macro handover success rate
As a small operator, they compete by using technology to provide superior service at competitive prices. Gross Coliseum’s installed DAS no longer met our capacity and performance requirements. OneCell provided superior performance at a much more attractive cost than upgrading the DAS. The entire qualification process, from first lab tests to live commercial use took just nine weeks. As a demanding use case, the graduation event exceeded the expectations and validated the advantages of this technology.
Since it was first announced in June 2014, OneCell has received wide industry recognition including being selected by mobile operator CTOs worldwide for the Outstanding Overall Mobile Technology CTO’s Choice award at the 2015 Mobile World Congress. In a recent study, independent analyst firm Real Wireless concluded that OneCell can provide the same or better service as DAS for up to 71% lower cost.
“Nex-Tech Wireless’s practice of leveraging technology innovation is a perfect match for proving the value of OneCell,” said Rod Gatehouse, vice president of marketing and product management, Airvana. “This deployment validates our C-RAN approach and OneCell’s commercial readiness, even in the most demanding of environments.”
It is not often that you face WiFi issues on the iPhone. Apple designed the smartphone to latch onto an ae network pretty good. But there are always exceptions. It is not hard to boost the Wi-fi signal reception/strength on the iPhone when it feels like things are slowing down.
Here are few point one can try and follow to enhance the signal quality: Restart Everything
Restarting a router is one of the first things you ought to try. As simplistic and silly as it sounds, restarting a router/Wi-fi modem clears a few clogs within the system. Restarting a router after letting it be switched-off for about a minute can actually work wonders if you have been facing intermittent WiFi issues. While you are at it, you might also want to restart Wi-fi on your iPhone. You just have to turn off the toggle, wait for a minute and then switch it on.
Have got a case on your iPhone. That could be interfering with the WiFi reception. No case is designed to block the Wi-fi – at least, not consciously. Since most cases are TPU, plastic or silicone rubber, they have no effect on the reception but if you’re using a case that goes a bit beyond these materials, it might cause an issue. The easiest thing to do, in this case, would be to remove the case-cover off your iPhone and test the WiFi reception
Setup DNS Manually on iPhone/iPad
Setting up a manual DNS in iPhone’s WiFi preferences is known to create a massive difference. Sometimes, it’s not about the Wi-fi reception at all. Technically, by altering the DNS setting, we’re not boosting the WiFi reception. We’re only going through some other DNS to fetch data from the internet.
Interference from Neighboring Signals – Change the Channel
One of the biggest issues in a neighbourhood with lots of WiFi networks is interference. It’s hard to exactly quantify or measure the impact of neighboring Wi-Fi signals but your iPhone’s Wi-fi latching technology works this way: it pings for the strongest signal and catches on to it.
The strong 2.4 GHz signal that most routers operate on a lot of channels. If you are in the US, you can pick a channel between 1, 6 and 11 or if you’re outside, pick from 1, 5, 9 and 13. There are softwares that detect Wi-fi signals from your neighborhood and tell you what channel these are on. You can then configure your WiFi to stream through another channel.
Get a New Router
Although the possibility of your router being the source of all WiFi troubles on your iPhone is very less, it does happen. A new router can fix this.
Routers usually don’t go berserk. In the off-chance that they do, it’s hard to figure out if it’s the router that’s causing the poor signal issue. One efficient way of finding it out is to use a spare router and test it for a couple of days. If WiFi strength is good and stable on the iPhone using the alternative router, you can say that your router has got problems.
This long omni-directional antenna is the best performing dual band antenna on the market.
The SC-100-L is a fiberglass, omni-directional antenna ideal for providing coverage for large buildings and warehouses. It is commonly used with SureCall dual band amplifiers. Provides 9 dB gain for 2G/3G coverage.
For best results, the antenna should be mounted in an upright position.
Mount the entire assembly to a 1 to 2 inch diameter pole (not included). The antenna should be mounted with the chrome tip pointing toward the sky (perpendicular to the ground). The white fiberglass portion of the antenna should be mounted above the roof line and unobstructed in all directions. The SureCall Dual-band Omni-directional Long Antenna (SC-100-L)is compatible with the following networks:
Wi-Fi is a fantastic new gadget, but its reach is only about 50 to 100 meters. Fortunately it is possible to build our own antenna cheaply (less than 10 US dollars) in an hour or two. Present days, more individuals, businesses and local governments are enjoying wireless internet access proliferating Wi-Fi hotspots, home, office, and public wireless networks. However, Wi-Fi users are rarely completely satisfied with the signal strength offered by the off the shelf Wi-Fi cards, routers, access points and USB adapters. Compounding to the coverage problems, many locate their routers, access points or desktop Wi-Fi cards in a closet, against the wall or under a desk, diminishing signal strength and limiting bandwidth. Wi-Fi signal booster antennas, also called Wi-Fi signal amplifiers are attached to routers or access points to boost the signal. Good quality and powerful Wi-Fi signal amplifiers can increase the signal strength threefold. Bidirectional Wi-Fi signal boosters increase the strength of transmitted, as well as received signals. That is, they work both ways. They boost signal strength by as much as 600%. They can be used as laptop Wi-Fi signal boosters and extend range of Internet access far beyond your home. The need for seamless, uninterrupted and reliable communication is one of the top priorities of every house. The wide access to some really useful information base, for every kind of user makes it extremely important to set up a repeater, which delivers high performance.
Repeater is a networking device which, as the name suggests, repeats the signal or increases the reach of the existing wireless network. Very often, it happens that a device has to be connected to an existing wireless network, but it is away in a remote place in the house or a building, where the signal strength is too low or unreachable. A wireless repeater is used in such cases to boost the signal strength or simply repeat the signal so that the said computer comes under the coverage area. Wireless signals are susceptible to a lot of data loss. When it comes to the wireless signal strength that will be received, the topography of the place where we stay is also a deciding factor. If a large number of trees or buildings come in between laptop and the router we are connecting to, the signal strength will be almost zero. Besides everything, the wireless network cards, that come inbuilt, have very limited power and range. The answer then lies in using a wireless signal booster. A simple solution is getting a wireless card with a higher power or attaching an external USB antenna to the laptop. Wireless signal boosters are simple devices and can simply be plugged into the USB port of your laptop. The taller the antenna of your wireless booster, the better the reception. The working of the wireless booster is pretty simple. It accepts strong signals from the router and amplifies them inside your network, thus increasing the signal strength to a great deal.
A wireless signal booster consists of two antennas – the transmitting antenna and the receiving antenna. The receiving antenna is connected to an intermediate amplifier. The other input to the intermediate amplifier is a radio signal source. The intermediate amplifier amplifies the difference between the two signals; the received signal and the radio signal, and passes it over to a low-noise amplifier. This is done to remove any unwanted signals. The low-noise amplifier is connected to the transmitter. The low noise amplifier further amplifies the received signal and sends it to the wireless card. The wireless signal antennas in the laptops are located internally. Generally, there are two parallel antennas located on the two sides of the LCD screen. The internal location of the wireless antennas causes bad reception of the wireless signals. So, the first problem that a wireless signal booster needs to solve, is to provide an external high gain antenna. This antenna needs to be directed to the access point. The biquad is defined as a high gain antenna with an exceptionally large beam width. The problem faced with high gain antennas are the beam width that the antenna is capable of.
The Aim is to design different Wi-Fi booster antenna and analyze the performance to improve the signal strength for long distance. To overcome drawbacks of existing technology such as
• Manually Designed Wi-Fi Cantenna and its Testing in Real-Time Environment
• The High Cost of booster Antennas available in the market
The booster antennas available in market costs very high in dollars and are easily available in foreign countries. This adds to the cost of travelling or shipping the product to the user destination. This aims at increasing the number of access points but in spite of these there are some hot spots or locations where the range is not available because of which we receive weaker signal strength. It provides us with improved signal strength. To achieve this, we need to study the various parameters of booster antenna available in the market, and increase the signal strength thereby improving the performance of our antenna.
The Work can be done on Real –Time basis by testing the performance of Booster antenna in the campus at locations where the signal strength is weak. The proposed plans of work for booster antennas include:
• To Design different booster antennas and then analyze their performance to increase the signal strength (Manual building and software based testing).
• To Implement Wi-Fi monitoring application.
• Test booster antennas for internet connectivity.

Need a more powerful solution than a Verizon Jetpack® for your residence or a small business
Don’t have Internet access
Have dial-up or low-speed Internet service
Need a router that can also be used as a backup solution when your existing broadband service is down
You can take advantage of high speeds from America’s fastest 4G LTE network at your home or small office. Access the Internet on up to four wired Ethernet-connected devices and over 20 Wi-Fi devices, like tablets, computers and gaming consoles.
You can connect over up to 20 devices via Wi-Fi at one time and up to four devices with a wired connection (Ethernet).
Actual range and speeds will vary based on the radio frequency conditions and obstructions within your home. Most devices should be able to connect within 150 feet of the router and may be able to connect at up to 300 feet unobstructed.
You can connect your devices to your router with Wi-Fi or with an Ethernet cable.
Connect with Wi-Fi
There are two methods of connecting your router to your Wi-Fi network:
Push ‘N’ Connect (also known as WPS or Wi-Fi Protected Setup)
Press the Push ‘N’ Connect/WPSbutton on the front of the router.
On your mobile device, go to the connection manager and select the WPS connection s
If prompted for a WPS PIN, enter in the WPS PIN found on the label on the back of the router.
o Wi-Fi Network Name and password
Note: Your Verizon 4G LTE Broadband Router comes with a unique Wi-Fi Network Name (SSID) and password located on a label on the router.
Ensure that your device supports Wi-Fi and that it’s enabled.
Using the device’s wireless connection manager, connect to the router using the SSID and password information provided.
Connect with an Ethernet cable
Insert one end of an Ethernet cable into the yellow Ethernet port on the back of the router.
Insert the other end of the cable into your device, such as a laptop or gaming console.
SureCall’s new TriFlex-V is a tri-band cellular booster solution that’s ideal for homes and small offices <a/>where cellular reception is weak due to distance from towers, topography, building materials or structural design. This kit is specifically designed for Verizon 2G, 3G and 4G voice and data reception. These competitively priced booster kit provide enhanced voice and data for all indoor environments, the kit is designed to provide the ultimate in cell reception. The TriFlex-V signal booster kits support up to 10 simultaneous users.
Inside the extender (under the hatch cover on top toward the rear) is the GPS antenna. This antenna has NOTHING to do with the strength of the cell signal or the quality of the call. GPS is there to properly synchronize calls to live cell towers. I bring this to your attention because the folks who sell aftermarket external GPS antennas occasionally will lead consumers to believe that their extender will work better and you will “get more out of your extender” if you buy an external GPS antenna. Poppycock. Very simply, if the GPS LED is solid blue you don’t need another GPS antenna. Repeat, if the GPS LED is blue you are good to go. See below if your GPS LED is red. In that case you may or may not need an external GPS antenna.
With that question hopefully settled what remains is; do you need a different cellular antenna? There are indeed aftermarket cellular antennas that can a) increase the range of your extender, and b) focus the signal in a specific area. The stock cell antenna is omnidirectional or just “omni”, meaning it covers a full 360 degree area. Replacement antennas may be omni as well or be directional to cover a specific area. Just remember in all these examples that unlike WiFi, you can’t password protect your extender! It’s open to whoever the signal reaches to.
A strong Wi-Fi Cell phone booster connection brings about a lot of benefits like fast internet browsing, reliable online video and audio chat, quick downloading, etc. Sometimes you just need to move only a few inches physically, or to change some easy configurations to boost the wireless signal so that you get a high speed connection.
