For the very first time in Bangladesh, three members of an international Yaba tablet syndicate were arrested by rapid Action Battalion(RAB) in Bandartila area of Chittagong,Bangladesh. RAB-7 media ASP mentioned that the satellite phone is an indicator of their international counter parts. The satellite phone is from Iridium brand. People who are against humanity
use this type of phones to continue their crimes. However it is a matter of great regret that Bangladesh does not have any technology to track or monitor this system.

What is Satellite phone:
Generally, people are familiar with mobile network phones which get its connection from mobile company's own tower. However satellite phones get signal directly from satellite. So, it can be used in any place and there is no need of network tower. Thuraiya satellite mobile was a great advantage for Iraq and Afghanistan war.
Differences between Mobile and Satellite phone:
There is no such differences between satellite phone and mobile phone but only in network system. Terrestrial network is not used here but get connected directly with satellite. That is why this phone can be used in any place or in any weather. Specially for navy and army these phones are used in most of the cases.
Disadvantages of Satellite phone:
This technology started in 18th or 19th century along with mobile phones. Now-a-days these phones have become like smartphone size. However the disadvantages are-
1) Satellite reception rate is very poor without open field.
2) Satellite phone can not connect within home or offices that's why it is not renowned like mobile phones.
How does it work:
Satellite phone works in various ways. In some cases it uses Geosynchronous orbit. It means mostly 3-4 satellites are stable in the orbit of earth and connection in the whole world can be established by contacting those. Those satellites are very heavy (~5000kg) and very expensive to set in the distance of 22000 miles away from earth. That is why good connection is needed with which satellites are set in less distance with earth in low-earth orbit. These are set in only 400-700 miles away from earth and they usually move around the earth within 70-100 minutes. These satellites can give coverage within 2800 km and the speed of message passing in mobiles is from 2200 bit/s to 9600 bit/s.

Expenses of Satellite phone:
Satellite phone has become very expensive now-a-days. Sat-to-Sat call rate is $0.15-$2 but Sat-to-mob call rate iss $3-$14. Moreover many company offers upto $15. And pre-paid card of satellite phone is from $5000 to $10000.
Users of Satellite phone:
Iridium is the leading company which provides this service with the help of 66 low-earth orbits. Government offices, military, navy, Ministry of Disaster Management and Relief, foreign embassies, The recreational user that travels outside of cellular range, Recreational boaters that travel off the coast, Captains of chartered boats etc can use this phone with the proper permission of government. In the whole world only 7-8 companies provide this service. However this service is totally banned for North Korea, India, Cuba, Myanmar, libya.
Satellite phone for general people:
This phone was not available for general people in 18-19th century. However the company SPOT will provide this phone in 38000 BDT. This phone is called Spot Global phone which is kind of similar to old version Nokia phone. With the help of this phone one can call from any place.

Crimes with this technology:
Mobile phone can be easily monitored but because of high and expensive technology some country can not monitored satellite phone properly. That is why for smuggling drugs, golds, weapons etc they usually use this technology so that they can communicate from any rural place.
This useful technology can be a great help gor humanities to invent something necessary but now this technology is being harmful. And necessary steps should be taken immediatly to stop those activities against humanity.
Freelancing in Bangladesh
Bangladesh, despite of a low-income country has maintained an impressive track record on different sectors. For becoming a middle-income country youths are making great impact on country's economy. They are struggling with poverty, unemployment and nasty political corruption. Freelancing is their main weapon in this struggle.
Markets and business owners are now being interested about Bangladeshi freelancers because of the working ability, skillful tasks and cheap rate. According to BASIS(Bangladesh Association of Software and Information Services) more than 1lac Bangladeshi freelancers are adding 1crore BDT per day in Bangladesh economy. Lots of owners daily post their jobs to freelancing sites like oDesk, Freelancer.Com, eLance.com and so on.
Freelancing is all about how to efficiently, flexibly one can sell his/her skill. Some highly demanding freelancing jobs are- SEO (search engine optimization), Website development, Data entry, Blogging and Affiliate Marketing Expert, Article writing, Graphic design, Software Development, Mobile and Web apps development etc.
Experts and some political leaders' opinion about freelancing is- despite of having so many obstacles youth are carrying this sector very skillfully and Within 2021 we can change our Bangladesh as a middle-income country.
Freelancers opinion about this sector is- We are working hard and day by day we are improving but the obstacles which should be removed are,
1) Cost of internet should be minimized.
2) Various rules on Dollar should be stopped.
3) There should be some systems in Bank for freelancers only to take money on holidays.
4) Government should take more steps like seminar, workshop etc to improve this sector as well.
In Bangladesh not only single person but also many companies are doing freelancing which is not only removing unemployment but also increasing ability of our country to compete with developed countries.
New trend in cloud communications
"Clouds come floating into my life, no longer to carry rain or usher storm, but to add color to my sunset sky."-- Rabindranath Tagore.
Now cloud has floated into the technical world such as computing, communication etc. also but with vast differences. Cloud communications are Internet-based voice and data communications where telecommunications applications,switching and storage are hosted by a third-party outside of the organization using them, and they are accessed over the public Internet. Messy telecom hardwares are taken care of and Cloud APIs are introduced for the communication.One of those APIs I have a great experience to work with is "TWILIO" API.
Fig: Cloud communication working with Mobile
Twilio is a quick service provider to get connected with other party over phone or SMS. Different applications with whom an organization can work with and consumer can consume the facilities like appointment remainder, call tracking, moderated conferencing, SMS notification, audio recording, browser-browser call, browser-phone call etc.
Fig: TWILIO API
User has to buy one number from Twilio and they will authenticate that user with some necessary information. From user end, user will call to the customer. Initially call will be placed to the Twilio server and it will authenticate those informations and establish the connection between user and customer. And for this service they will cost a certain amount.
Fig: Twilio API with call and sms
I have developed two projects using this API.
1)Booking to barber/salon over phone or by SMS. IVR (interactive voice response) system has been also using to get
immediate response to accept/reject those requests.

2) Wishing people on their birthday with automated voice and mp3.

Leading companies also rely on Twilio for their quick service --- http://www.twilio.com/customers
Twilio has enhanced the telecommunication world with all its facilities and consumers are satisfied with the quick services of this API.
[Bangladesh Building Collapse] Woman workers attended the job with life risk in the morning
The 9-story building where garment factories were located is no longer seen by any single people. At the moment (2013.5.3), persons killed accounts for over 500in the devastated accident happend in Dhaka, Bangladesh.
Here is summarlalized report by a friend of mine, one of journalists from Banglaesh.
Photo: retrieved from cnn.co.jp
the Garment building name is Rana Plaza. 9th floor building. but it had permission till 6th floor from municipal authority . From our view, the guilty is the owner of RANA Plaza since he made 9th floor by violating permission of 9th floor. But our question why then Govt authority did not sue this owner due to his building code violation ? because Govt Authority has been managed by him somehow either politically or financially Rana had sat at the nexus of party politics and the powerful $20 billion garment industry that drives the economy of this deeply impoverished nation.. Whatever the reason, it means Govt authority is also liable besides Mr Rana. That is the first point . 2nd is that day before the accident , already it was seen building broken for which Brac bank withdraw their offices from there one day before the accident completely . But Garments owner did not shift. The owner told there will be no accident . they push all of their employees to come in the factory to attend office . for this all 3 garments owner pushed their workers either attend the office or fire from job. So you know the condition of workers. So they attend the job with life risk in the morning. after the collapse investigation says , there were many heavy machinery in the each floors for which extra load the capacity could not take. For this reasons , building collapse. also others say the land was not solid soil. it was muddy or something like pond area before building . Land filling was not properly for which building foundation was weak . From experts view, the guilty is the Govt Authority since they did not monitor from beginning of building construction and finally during collapse nobody monitor it had 6th floor permission but it is 9th floor. Rana is guilty, garments owner is guilty among all Govt officers & Politicians are guilty since they gave shelter them to build and maintain such building .
