A satellite telephone, satellite phone, or satphone is a type of mobile phone that connects to orbiting satellites instead of terrestrial cell sites. They provide similar functionality to terrestrial mobile telephones; …
Sat phones rely on a network of satellites that are either fixed above the Equator (Geostationary), or in Low Earth Orbit (LEO) anywhere from 500 to 1,000 miles above the earth. Sat phones are rarely affected by violent storms and, depending upon their system architecture, work virtually anywhere in the world. The devices weigh a few ounces and may be about the same size as your cell phone.
Traditional sat phones buyers are government and public safety agencies, energy companies, shippers, and search and rescue organizations. But an increasing number of private individuals are buying sat phones as an insurance policy against losing their capability to communicate with the world.
While you may never have considered buying a sat-phone, you may change your mind after learning a few key facts, especially when you consider the drastic reduction in the cost of equipment and airtime that has occurred in the past few years.
The primary satellite network infrastructure was built by Intelsat in 1965 and changed the way the world communicated. It spawned incredible capabilities, especially in the maritime world where one company now supplies communications to virtually every cruise ship in the world so its passengers and crew can talk, text, and email from sea.
In about 1997 the first low earth orbit satellite network was launched by Motorola to provide handheld service anywhere in the world. The system was called Iridium and consisted of 66 satellites that crisscrossed the globe on a continual basis. The constellation of satellites communicated directly with each other in space, and then to ground stations in thirteen different locations around the world. Handsets could communicate with any phone, anywhere through this infrastructure. Ultimately, Iridium went bankrupt due to inept marketing and unrealistic expectations of user demand, but the network survived and is now thriving.
At about the same time, GlobalStar launched a similar network, but with entirely different architecture, called bent-pipe. This system relied upon 48 satellites that were placed in orbit about 900 miles above the earth. Globalstar provided cellular-equivalent audio quality, unlike Iridium which has an extremely narrow bandwidth. This means that audio intelligibility on Iridium (and Inmarsat) is a bit more difficult to understand.
Globalstar went bankrupt in 2002. It has lost about half of its first generation satellites and is just trying to rebuild itself. Presently, its service is very limited and not entirely reliable on a 24/7 basis.
A regional network, Thuraya launched in 1997 and began operations in about 2001. Based in the UAE, it was designed to serve Europe, Africa, and the Middle East. Its handsets are dual-mode, which means that subscribers can roam on both GSM networks as well as talk via satellite. They now have sold more than 600,000 handsets.
The fourth and latest entrant into the satellite phone arena is Inmarsat.This company began operations to supply communications to the maritime industry in 1979. In 2010 they introduced their IsatPhone-Pro handset that talks through their global constellation that covers the planet except for the North and South poles.
The four satellite networks provide essentially the same services, but in very different ways, with different kinds of technology, coverage and quality. Which system is right for you depends on how and where you will make and receive phone calls, and what other services you may require.
How to Select a Satellite Phone
See my interview with Eric Verheylewegen, the General Manager of GMPCS, one of the largest satellite phone vendors in the United States and Europe. We discussed in detail the different satellite phone options and limitations. GMPCS sells and provides 24/7 technical support for Iridium, Inmarsat, Globalstar, and Thuraya.
If you purchase a sat-phone, expect to spend between $600 and $1700, depending upon the network. All of the phones are lightweight, small, and replicate the functionality of your cellular telephone. Some have Bluetooth and WiFi capabilities so you can use a remote headset, and wirelessly connect your computer for data access.
Satellite air time is not expensive in comparison to typical cellular roaming charges in foreign countries. This is especially important aboard a cruise ship where communications costs can be exorbitant. Read my article about the high cost of communicating at sea and how that is about to change
Airtime can be prepaid or obtained on a monthly service contract. Either pricing scheme can be very attractive and inexpensive in comparison to cellular roaming rates if you travel to Asia, Africa or South America, where calls can cost up to $6.00 per minute in some venues. The important thing to remember is that land-based cellular networks offer coverage anywhere there are population centers or routes. In contrast, satellite networks offer global service and do not require towers.
Selection of a satellite handset should be based upon a number of technical and user-criteria. These include:
- Cost of handset
- Economics of use
Airtime pricing plans, either prepaid or monthly postpaid, and rollover minutes, and the cost of calls to landline and other mobiles
- Ease of use
- Geographic coverage requirements: global or regional
- Where the phone will be used and special option and feature requirements such as GPS, phone tracking, GPS location transmission, and panic alarm
- Bluetooth and WiFi capabilities
- Ruggedness and compliance with military specification
- Data capabilities including email, text, and messaging
Satellite phones v. Cell Phones
All satellite phones have a number of common characteristics that you need to be aware of in order to select the one that will work the best for you. The most important point to understand is that sat-phones are not cell phones, and they work on an entirely different network architecture and radio propagation characteristics. There are certain inherent limitations as to how they operate, and where. While a satellite phone will work just about anywhere in the world, they will normally not work inside of buildings or any kind of structure that blocks their view of the horizon. There is no equivalent to Blackberries or iPhones in the satellite world andthey will never replace cell phones but are a good insurance policy against the failure of cellular networks.
- Antennas: Their antennas are external, not internal, which means they must be extended to function properly, both to send and receive calls. The phones generally will not work if the antennas are retracted because of the way radio waves are propagated, and the frequencies that are used. So, you cannot walk around with a sat-phone in your back pocket and expect to reliably receive phone calls.
- International phone numbers: Satellite phones generally have special international numbers, although some, like Globalstar, also have U.S. and Canadian numbers assigned. Most of the companies have what is called Direct Inward Dial capability, which means that you can get a U.S. number to call, then overdial(using touch tone) the actual number assigned to the handset.
- Calls to these phones can be very expensive from the public network, up to ten dollars a minute, depending upon the carrier and pricing plan. If you intend to receive calls on your satellite phone, be sure to select a carrier that has Direct Inward Dial, or overdial capabilities.
- Global coverage: While some of the satellite carriers provide global coverage, it is not absolute. Depending on where you are located there may be dead spots. This is a function of your surroundings, foliage and trees (like in a jungle), high buildings, mountain ranges or other obstructions. It is also dependent on how the satellite constellation is designed. Inmarsat does not adequately cover the North and South Pole, while Iridium does. See my interview with Pierre-Paul Tengwo, a Senior Supervisor at Inmarsat Operations Center in London for a description of their network and how they can dynamically optimize it for specific communications requirements.
- Voice quality: The voice quality on many of the networks may be a lot lower than what you are used to with cellular. That is because the bandwidth is severely limited to optimize power requirements. There may also be a delay, called latency, between when you talk and the other party talks. This can happen when you are talking through a system that has satellites in geostationary orbit, like Inmarsat.
- Handset design: All of the sat-phones are small and lightweight, some not much larger than cellular handsets. While they all function similarly to your cell phone, there are design differences in terms of antennas, displays, soft buttons and options. Inmarsat probably offers the least expensive and easiest to use phone, but it does not have certain options that Iridium provides, including truly global coverage. All of the systems, regardless of handset, now optimize the connection between you and the satellite by determining your exact position using GPS.
- Email and Text: All phones offer text messages, and most will also allow sending and receiving of email. In that regard they offer almost the same service as your cell phone.
What you need to know about the different satellite network
There are only two truly global and reliable networks: Inmarsat and Iridium. I have extensive experience with Globalstar and do not believe it is presently a reliable network, nor does it offer service worldwide. There are fundamental differences in the three networks that you are most likely to use: Iridium, Inmarsat, and Globalstar. Thuraya is a dual-mode handset (satellite and GSM) and does not work everywhere, but is very popular because of handset costs and size, and airtime rates. Unfortunately, Thuraya does not work in North America.

WhatsApp on Reliance Jio Phone? No, you may not see the app on 4G mobile soon
Want to know if the Reliance Jio Phone will support WhatsApp? Latest reports suggest that it is unlikely that the Jio Phone will get the popular messaging app anytime soon.
Want to know if the Reliance Jio Phone will support WhatsApp? Latest reports suggest that it is unlikely that the Jio Phone will get the popular messaging app anytime soon. When Mukesh Ambani launched the Reliance Jio Phone, everyone was curious about the features the 4G mobile will get. However, the biggest confusion was over the support for WhatsApp which is one of the most used apps, not only in India but globally too. The availability of WhatsApp may prove to be a crucial aspect of the success or failure of Reliance Jio. This is mainly because the Facebook owned app is one of the biggest all over the world and Indians are its highest users. But now, according to a report in The Indian Express, the JioPhone may not support WhatsApp, at least initially.
Recent reports, including the one in Factor Daily, claimed that Reliance Jio Phone will have a special version of WhatsApp. The report had suggested that both Reliance and WhatsApp had been in preliminary talks with an aim to come up with some form of WhatsApp on the 4G mobile. However, the IE report said that WhatsApp software engineer Alan Kao, who interacted with the media at an event in New Delhi, had said that he was not aware of any such plans to expand to platforms other than the ones it is already available on. Reliance Jio, meanwhile, runs the KaiOS, which is a Firefox operating system which does not support WhatsApp.

The interaction of Alan Kao and Indian media was targetted at discussions on end-to-end encryption and curbing the spread of fake news on the messenger. IE said that a question was raised around the encryption feature and the development going on if it launches a special version for a 4G feature phone. Interestingly Kao said that he is unaware of “plans to expand to other platforms”. He added that encryption was a priority even on Symbian OS in Nokia phones and BlackBerryOS too.
BSNL launches satellite phone service
Introduction Most of the software companies are running Load Testing on their products. Load testing is one of the most important testing types today. On the 6/6/2008 Amazon web site crashed …
Step 1 – Identify Objectives
The purpose of this step is to identify and write the performance objectives of your application. The key question you should ask yourself is:
“How should my application behave under load?”<o:p />
Throughput – The rate of successful message delivery over a communication channel. Example: the system must support 100 requests per second.
Resource utilization– A frequently overlooked aspect, Resource Utilization defines how much resource your application is consuming, in terms of CPU, memory, disk I/O, and network I/O.
Maximum User Load– Determine how many users can run on your testing hardware configuration.<o:p />
Step 2 – Identify Key Scenarios (or profiles)
Scenarios are anticipated user paths that generally incorporate multiple application activities.<o:p />
Key scenarios are those for which you have specific performance goals or those that have a significant performance impact. These scenarios represent business activity of users over time.<o:p />
Step 3 – Identify the workload
For an existing application this information can be provided from IIS log/counters as described in step 1.
For a new application this information can be based on market research, historical data, market trends and prototypes. <o:p />
Step 4 – Identify Metrics
Service level metrics: Service level metrics can help to measure overall application throughput and latency, or they might be tied to specific business scenarios.
Step 5 – Pick Load Test Tool
Step 6 – Create Test Cases
- What is a test case?<o:p />
- A group of activities involved in a scenario/user profile.<o:p />
- The test cases are created based on the scenarios and the profile mix identified in the previous steps.<o:p />
Test Case: Search phone owner
Example: 400 users for 1 hour<o:p />
And load test expected results for Test Case: Search phone owner :
Step 7 – PrepareUnderstand Your Load Environment
When CPU usage is 100% the computer is not creating the needed load and we will get false information so this is our first bottleneck.
Do you think 1Mbps is enough bandwidth for 10,000 users?
No! 10,000 users cannot work together on 1Mbps bandwidth, this is the second bottleneck.
Step 8 – Run It Step by Step
Incrementing the number of users slowly will make it easier to find the exact point/threshold where the system crashes or hangs due to load. Starting the tests with a large number of simulated users will prevent us from detecting that point/threshold efficiently.<o:p />
Step 9 – Run
Step 10 – Analyze and Evaluate the Results
Can you say that I say maybe…
That being said, I’m sure that for expert performance test engineers, the above rules of thumb are obvious – you have tried them in a trial and error situations. For all the other testers who would like to know how to start a performance and load test, and make things done, I hope I have explained in simple enough words, what are the basic step by step actions that I suggest to follow in order to create a good, precise and powerful Load Test suite. Good luck friends!
Best Practices Overview The purpose of this tutorial is to present some of the best practices we have developed at Web Performance. Through our Load Tester product development and load testing …
1. A reasonably accurate result right now is worth more than a very accurate result later. It is well understood that changes become more expensive later in the project. As a result, the quicker that performance problems are found, the more easily they are fixed.
2. Test broadly, then deeply. Testing a broad range of scenarios in a very simple manner is better than testing a few testcases very deeply. Early in a project, an approximate simulation of the real world is acceptable. Time spent getting each testcase to exactly mimic the predicted real world scenario or testing dozens of slight variations of the scenario is better spent testing a wide range of scenarios.
3. Test in a controlled environment. Testing without dedicated servers and good configuration management will yield test results that are not reproducible. If you cannot reproduce the results, then you cannot measure the improvements accurately when the next version of the system is ready for testing.
- Select the scenarios to be tested
- Pick a scenario and configure it
- Load test the scenario
- Repeat steps 2-3 until each scenario is ready, as schedule permits
- Combine the load tests and run a combined test
Once the scenarios have been rated on the Difficulty of Simulation and Importance, we order them. The scenarios that are easy to simulate and very important come first. Then we choose the scenarios that are either easy to simulate but only somewhat important or not as easy to simulate but very important. We usually alternate those – favoring the easy ones when schedules are tight. We favor the easy scenarios because experience has shown that the factors that cause performance problems are rarely related to the importance of the scenario. There is a lot of value in testing as many scenarios as possible very early in the testing effort. This gives the developers more time to troubleshoot and tune the application when problems are found.
- Ensure the testing hardware is dedicated to the testing effort. Testing on production systems that are being accessed by other users is a common mistake. Since it is generally impossible to tell what other users are doing, it will be difficult to determine if performance anomalies are the fault of the application being tested, the test configuration or the other users on the system.
- Ensure the application data (i.e. database) is in the same state for every test. As databases get populated with greater amounts of data, queries get slower. This may mask other improvements over time. In general, the database should be restored to a known state before every test. This can also make the testing effort much quicker – because it allows certain assumptions to be made in the testcase construction and configuration that can save a lot of time and effort.
- Change only one thing in the test environment at a time. Changing more than one factor at a time makes it difficult to assess the effectiveness of any of the changes.
Creating and customizing a testcase generally follows these steps:
- Record the scenario using a browser while the testing software records the actions.
- Configure the testcase to simulate multiple user identities (for any system with a login)
- Customize the testcase to supply different inputs (search keywords, for example)
- Replay the testcase to verify correct simulation
One of the ways we do this is to model variations of a scenario as separate testcases. For example, if some variations of a scenario require a user to visit a confirmation page while others do not, we would model these as two separate testcases. One reason is that modeling if-then logic in a testcase adds complexity and generally requires a script-based testing tool. Maintaining scripts is labor-intensive and increases the overall cost of testing. Second, unless measuring both variations is critical, we will generally only choose one of the scenarios earlier in the testing process to allow us to test more broadly. In later stages, we will come back to address the remaining variations.
2) HTML or XHTML validation
4) Ajax and JQeury functionality
5) Font size validation
6) Page layout in different resolutions
7) All images and alignment
8 ) Header and footer sections
9) Page content alignment to center, LHS or RHS
10) Page styles
11) Date formats
12) Special characters with HTML character encoding
13) Page zoom-in and zoom-out functionality
And obviously, you will have to repeat these tests on:
14) Different Operating Systems like Windows, Linux, and Mac
15) Different browsers (with different versions) like Internet Explorer, Firefox, Google Chrome, Safari, and Opera.
There are many free and paid cross-browser testing tools available in the market. You need to select the browser compatibility tool depending on your needs. If cross-browser testing is a critical part of your web project then you must allocate considerable time, resources and budget testing your website on different web browsers. Paid cross-browser testing tools can be also a good option for projects having browser dependent functionality. But for most of the projects, free cross browser testing tools are sufficient to verify cross-browser functionality
