Do Satellite Phones Work Everywhere?

do cell phones use satellites

You must have been gone through the time when you were in the middle of nowhere but you were unable to contact someone due to the limited cell phone coverage. Since the cell phones do not provide a network in various parts of the world because of the limited range of the cell phone terrestrial towers, therefore your travel series to the Everest or Sahara desert is usually ruined when you roam here and there for one bar of a signal that your cell phone can catch. To deal with this complex situation, technology has come up with the best solution that is “satellite phones”. It uses the sat phone plan for connectivity.

Who doesn’t love technology? We all do, it is such a magical feeling when you can video chat with the one you love who is several miles away, or when you put a simple key in the ignition to travel through many places in your car or heating your favorite food in seconds through the microwave. Technology has eased our lives in many ways, one of which is the satellite or sat phones. The question here arises is that do satellite phones work anywhere as it promises or not? In order to understand the coverage that sat phones provide, one must know what is a satellite phone, how it works?

What Is A Satellite Phone?

A satellite phone is a type of mobile phone that connects with the satellite rather than the cell phone towers to which the cell phone connects. The network coverage can range from a particular area to the entire earth depending on the type of service. Do cell phones use satellites too? No, not really, this is the reason that sat phones reaches to areas where the cell phone can’t. They let you call from anywhere around the world because their structure is out of the world. They do not depend on the towers but they transfer data directly through the satellites which are orbiting the earth. This huge technological leap let the sat phones to connect freely without the earth-based restrictions. Therefore they are the preferred communication devices for the areas which are poor or densely populated where natural disasters have destructed the system or where governments have put cell and internet restrictions.  Though a little bulkier, satellite telephones have all the capabilities that a normal smartphone has. The important thing to understand is that how the Satellite phone plan works?

How Does Satellite Telephone Work?

A good answer about the satellite phones how it works is described here. The satellite telephones rely on satellites to operate until now we are aware of this. But they tend to work differently which depends on the satellite system that the company deploys. Some companies go for geosynchronous satellites while some opt for low earth orbit (LEO) satellite systems. Each system has its own configurations, constellations, pros, and cons. The geosynchronous also known as GEO orbit or high earth orbit satellites stay in the same position in the sky and follows the earth as it spins. They are high altitude satellites which maintain a 22000 miles distance from earth and always centered above the Earth’s equator. They are large powerful satellites and each of them can cover a large area on the earth. If a company has a constellation of three to four GEO satellites than it can provide the network for most of the globe. They are meant to cater large volumes of data which means that the sat phones cannot only be used for voice calls but also for watching videos, sharing files, texting messages and much more. Thuraya and Inmarsat are the two companies that use geosynchronous satellites.

On the other hand, LEO is the low orbits satellites which are 930 miles away and are operated by the companies Iridium and Globalstar. The LEOs are considered as mosquitoes as compared to GEOs, but they possess various qualities. As they are very small, light and low in orbits, a company may need at least 60 satellites to provide coverage for all of the Earth. You may be in the range of two or more satellites at a particular time because they travel around the planet at 1700 miles per hour. These low and fast satellites provide better services as compared to GEO satellites as they require more time to process data. LEOs provide superior call quality, dependability and lower delays. The LEO satellite telephones are the preferred devices when you are in the emergency and need immediate contact. Though the LEOs are not suitable for watching videos, they are portable as compared to GEOs. However, an important thing to know about how do satellite phone plans work is that you need to have a line of sight in order to operate the satellite telephone, which means if you are indoors then it will be difficult to have a connection. If you are in the area when someone is calling you desperately but the connection doesn’t seem to fit then you will get a pager alert that someone wants to call you, once you move to a better location.

To be precise, the satellite phone sends signals to the satellite which then transmits it back down to the earth and here the station will route the call to the telephone network. Some cases also call for transmitting a signal from one satellite to another in order to transfer it to the Earth. The outbound calls done from the sat phones on the ground are transferred to the satellite in the line of sight and then reaches the correct satellite by traveling through some of the satellites in between and then transferred to the appropriate station at the ground.

Conclusion

Do satellite phones work anywhere is the tension that anyone who wants to purchase the sat phone is considered about. The satellite telephones have the capability to work around the globe though the conditions vary. The sat phone has to be under the sky in order to make a contact. Do cell phone use satellites? No, it doesn’t hat is why the cell phones cannot provide the coverage that satellite telephones can.

Green Card and Traveling Outside the USA

travel outside us

Once you become a permanent U.S resident, or get а TN 1 Visa, traveling abroad and back is easier. The new status of Legal Permanent resident (LPR) makes things easier. You will no longer be worried about expiration issues. However, you should be careful to maintain your American immigration status.

Maintaining your U.S Residence

It may seem simple and obvious but maintaining your home in the United States is important when traveling out of the country. If there is any indication or evidence showing you might be settling outside the United States appears, you will lose your status as an LPR. This is easily detectable by how long you stay outside of the U.S. If, for example, you spend less than a year as prescribed, it may show you have come back home. However, this is not enough evidence of your intention to make the U.S your permanent home. You may lose your U.S residency immediately you leave any indication of moving to another country.

Losing your Green Card during Travel

As soon as your green card is lost while outside the U.S, you need to report to the nearest U.S embassy or consulate. You will obtain a U.S Government Transportation Letter. This document will serve as a temporal replacement upon reentry to the U.S. In case the green card was stolen, you should first, report to the local authorities to obtain a police report. This report will prove to the officers that you are acting in good faith and that; you may not have sold your card.

Your credibility was based on criminal records, health conditions, the likelihood of becoming a public charge and so forth. Under certain circumstances, the grounds for inadmissibility are revisited during reentry. Some of the issues taken into consideration are; your absence from the U.S for a period exceeding 180 days, engage in illegal activity outside of the U.S, traveled while in the removal of extradition proceedings, or abandoned your status as an LPR. Other issues including attempting reentry via an unrecognized entry point or time.

It is easy to lose your status as a resident after making mistakes about traveling outside the country and staying too long or losing your card.

Travels as the Biggest Inspiration for Architects

travel and work

Inspiration travels are not a new thing. The world is full of wonders. Hence, it is an endless source of inspiration for unique ideas. People often travel for work instead of just for leisure. It is like a two in one deal. You not only get to move out of your comfort zone, boring surroundings and freshen up, but you can be actually motivated to be more productive at your work. In this article, you will get all you need to know about traveling (mostly about the Amazon River trips) and its influence on architects’ productivity and inspiration.

Do Architects Travel?

Architects have an interesting job. Their work combines multiple elements. It is art and science at the same time. We have a fair amount of famous architects to be grateful for given some of the most magnificent structures in the modern world.

The architecture also has a rich history. It has been a part of many ancient civilizations. The art and science of ancient architecture have been incorporated into the latest studies. That is why we can see the inspiration from history in modern architecture. It is not about how a building looks, it is also about its strength, feasibility, and convenience.

For years, architects have traveled the world to inspire themselves. The greatest architectural structures of our world cannot be conceived without interesting inspirations. Inspiration does not always have to come from other physical structures. Nature itself provides interesting ideas, which we can incorporate into our infrastructure.

Amazon and Architecture

Architects from around the world travel for work to come up with unique ideas for their projects. This has taken many of them towards Amazon, which is the largest rainforest in the world. While it is shared by several countries, the biggest part is contained in Brazil.

It is often referred to as the heart of the Amazon and home of 2 million people. The city is in the depths of the jungle. Plane or the single highway into the town can only reach it.

The architecture of the city is quite interesting. While native Brazilians lived in the rainforest, the Europeans that came during the 1800s left their own architectural influence. They wanted to make Brazil look like the Paris of the Amazon and they made this possible in an Amazonian manner.

Brazil, and even other countries that share the Amazon River have plenty to offer to the architects who travel for work in order to find new ideas.

Overview of the Brazilian Architecture

Let us start with the Brazilian houses. Most of the houses crowd around the river. You will see boats scattered along the edge of the river, as it happens to be the livelihood for many living in the town. It creates this picturesque aura when viewed from afar. Architects would be interested in what materials the local people make use of.

The Sao Sabastio Square in Manaus features a stone floor that is more than just a stone. It is actually a motif representation of the Rio Negro and the Solimoes rivers, which make up the Amazon River.

When talking about some vintage-style architecture, Brazil will not disappoint you as you can experience the Amazonas Opera House. It was built in 1882 and its design can be credited to the Italian designer, Crispim do Amaral. He spared no expense when he mapped out a 701-seat theater. While it features Venetian glass blown chandeliers and Rococo furniture, it also contains the local Brazilian wood. The Italian designer sent the wood to be crafted in Europe. In one of the Palace’s private corners for the trompe l’oeil, you will find a floor of light and dark-colored wood. This is again another representation of the rivers meets.

Some of the city’s beauty is in a dilapidated condition now, but it does not take away the charm. Architects will still be able to find something during their inspiration travels. For example, you will witness Grand Art Nouveau atrium and regal neoclassical buildings combined with thatch roofs.

Taking the Amazon Boat Tours

In order to discover the Amazon and the town beyond in their full glory, an architect seeking inspiration should indulge in Amazon boat tours.

You can choose a tour that suits your preferences. Since the area in the Amazon is vast, you can always come back, taking a different type of tour to keep discovering. The essence of the Amazon in terms of architecture is that you do not just have to explore the cities and towns to find inspiration. The rainforest itself is an inspiration. Especially, when the architects of the world are moving towards greener ideas.

Amazon is history and nature combined in one package. An architect would simply love it. If you are one seeking to travel for work and gather new ideas, then you should definitely visit Amazon. It is a classic vacation on its own, where you can meet amazing tourists and local people, as well as motivation to make something great out of your latest project.

How to Travel to the Amazon River?

If you are planning to visit the Amazon region to seek ideas for your architectural project, then you will have to hire a cruise boat. These are river boats that offer varying tours through the Amazon. Depending on your budget and what places you would like to experience in the region, you can select the type of cruise and the itinerary.

Summary

Amazon River cruises will give you the time to appreciate the beauty of the Amazon Rainforest and the islands and towns that lay beyond. Travel for work and not only. Visit interesting places in Brazil and the other countries that share the Amazon, because they are worthy of note.
