Mobile towers and Wi-Fi equipments are going through a lot of improvement and development day by day and the technology is continuously evolving to greater heights. Presently they are a focus area in contemporary business as the customers have already increased using these services and there is a large scope for increased customer base in the future. The detailed answers to the queries asked is as below -
a) What is the difference in Mobile tower signal vs WiFi signal? -
For making the mobile data available in every place the mobile towers are used to first receive the mobile data by its own antennae in it and then transmit it with the transmitters mounted on it. There are associated electrical and electronic circuits in it for that purpose. The mobile towers are generally mounted on raised structures like buildings or hillocks in a town or city. Depending upon the working capacity of these towers they will be able to provide the data within some range which is known a cell in technical terms. That is why they are called cell towers also. So, a network of these cells adjacent to each other would be able to give a good coverage in the area by erecting more mobile towers for more coverage in terms of the area.
On the other hand a Wi-Fi is a device used for accessing the mobile data within a limited area like we are using in our houses or offices. These devices are known as routers and provide good wireless signal within the specified area. These are password protected so that your neighbour cannot use your data.
b) Is the signal dangerous of both or any? -
The mobile tower emits Radio Frequency and if one stands very near to it then it could warm up the individual body with those radiation. But generally towers will be erected on raised structures and their radiation level at the ground level where we are standing is almost nil and there are so far no known studies which confirm their bad effect on health.
Generally the signal energy levels in Wi-Fi devices, Mobile phones and Bluetooth are kept at lower sides to avoid any undesired effect on human beings but there are many studies which suggest that people living in Wi-Fi/ Mobile/ Bluetooth environment for a long time can get some disorders like oxidative stress, sperm/testicular damage, neuropsychiatric effects including EEG changes, apoptosis, cellular DNA damage, endocrine changes, and calcium overload. That is why its continuous use is discouraged. It is also advisable to use earphones and keep the device away. There are many precautions which can be taken to avoid the harmful effects of these radiations. More research and studies are on the way and depending on those results new regulations would be prescribed.
c) What give better network or connectivity? -
Both have different purposes. Tower is for a bigger area that is the cell to which it has to cater. It is primary thing and it should give a good signal otherwise the connectivity in the whole area would be poor. Wi-Fi is for a small campus and it has to boost the signal and provide it effectively in the area to the user or users for a seamless experience of mobile data. If the tower is giving poor signal then Wi-Fi would also be of limited use. They are interrelated.
d) What is the range of each i.e. Mobile tower signal vs WiFi signal? -
The range of tower signal would depend on its power and design but the normal towers in our towns and cities are generally able to give signal up to a distance of 1.5 Km to 2 Km after which another tower needs to be placed.
On the other hand the Wi-Fi routers that we use in our houses or office complexes are able to give a signal up to 30-40 meters in indoor conditions and about 80-90 meters in outdoor situation.
e) What is the technology used in Mobile tower signal and WiFi signal?
There are combinations of technological features in these installations and right from the earlier Radio telephony to present day 4G/ 5G technologies everything is embedded in them in much modified form for better signal delivery and low noise to signal ratio. The concept of dividing the city in cells and feeding them with towers is already a technological breakthrough. Then there are some frequency spectrums used for different types of services. I am afraid that it is itself a big subject and we can only mention these main constituents here.
Knowledge is power.
