Miscellaneous Concerns Can a Cell Phone Case affect Signal? The farther away you are from a cell tower, the weaker the signal gets, which leads to the "fish tank" voice and the constant say-and-repeat moments. Obviously, this does not bode well for your cellular signal. They can disrupt the signals sent to and from a satellite, and produce changes in the Earth’s magnetic field. These so-called solar flares produce shock waves that travel through space. Cosmic Events: Solar Flares and Cell ServiceĮruptions on the surface of the sun send plumes of gas into the atmosphere, and have been known to disrupt mobile phone communications. If you live on one side of a mountain, and the only cell tower in your area is on the other, you’re not likely to get good reception.Ĩ. Geographic features are a common reason for cell signal obstruction. Hills and Valleys: Why is Cell Service Bad on Hills and Valleys? Just like other weather, snow can adversely affect cell coverage.ħ. You might also wonder if snow affects cell phone reception - it can. If your home is surrounded by large, coniferous trees, these can be causing a massive drop in your cellular reception. Mother Nature: Do Trees Affect Cell Phone Reception?ĭid you just walk into a grove of trees? The leaf canopy can block some cell signals and cause your call to fade or drop altogether. Now that you know where it is, you should have no trouble avoiding this issue.Ħ.
Where exactly your embedded antenna is depends on you phone model, but a little bit of searching, and you should be able to find it.
If you’re not careful how you’re holding the phone, you can block the antenna, and lose your signal. Today’s phones have antennas embedded inside the phone. That’s partly because of those exterior antennas. The phones were heavy and unwieldy, but their signal was pretty consistent. Sure, they were as big as shoe boxes, but they also had exterior antennas. Your phone needs energy to maintain a connection with a cell tower, and it may struggle when its battery is low.Ĭell phones transmit and receive electromagnetic waves, which can be affected directly by weather phenomenon such as humidity, heavy cloud cover, thunder, lightning, wind, rain, snow and ice.Ĭlose your eyes and picture the early days of mobile phones. If you’ve been putting off charging your phone battery, you may find yourself with a weak signal when you need it most. Low Battery: Does Low or Faulty Cell Battery Affect Cell Reception? Read more on the materials responsible here.ģ. If you routinely notice service fading in and out as you walk around your home, or if your signal improves when you stand near a window or door, it’s likely your signal is being blocked by metal construction material. Metal and new-fangled tinted, low-E glass are the two materials most responsible. The building material of your house, car, place of work, or run-of-the-mill shopping mall is the number one culprit for weaker signal in America. Building Materials: What Building Materials Block Cell Phone Signal? If your call is transferred to a tower that’s already full, your call could be dropped.Ģ. Once your phone has linked to a tower, you are unlikely to lose your call, but the more phone traffic that fights for a spot, the weaker your signal can become. Chances are, most if not all are doing the same thing you are: texting or talking on their phones.Īll those signals are fighting for space on the nearest cell phone tower.
Take a look at all the other parents sitting in their cars in front of the school, or all those other people caught in rush hour traffic. By exciting particles at their optimized sizes with the corresponding optimized laser wavelengths, we achieved a detection limit of roughly around 100 pM and 80 pM for NCs and NBs, respectively.You think to yourself, “I’ve got to change carriers.” Not so fast! Chances are your carrier is not at fault (well, not always). Our results clearly show that: (1) the excitation wavelength discriminated particle shapes regardless of particle sizes, and the maximized Raman enhancement was observed when the excitation wavelength approaches the SERS peak (provided there is significant local electric field confinement on the plasmonic nanostructures at that wavelength) (2) at the optimized laser wavelength, the maximum Raman enhancement was achieved at a certain threshold of particle size (or silver coating thickness). All these nanoparticles were used as SERS substrates for thiram detection, and the Raman intensities with three different lasers (514 nm, 633 nm and 782 nm) were recorded and compared. Monodisperse nanocubes (NCs) and nanocuboids (NBs) were synthesized and their Ag shell thickness was precisely adjusted from ∼1 nm to ∼16 nm. We systematically investigated the size- and shape-dependent SERS activities of plasmonic core–shell nanoparticles towards detection of the pesticide thiram.
