Will Free Roaming hurt Dual sim phones

Recently all the blogs have been talking about the rise of Dual SIM technology in India and how some phone manufacturers have capitalized on this increasing demand of Indian phone users by making most of their phones supporting dual-SIM functionality.  Dual-SIM phones allow users to pick service providers of their choice and make best use of their offers. One can have a SIM for voice and text usage while another for data usage or even use two separate SIMs from two cities you visit frequently, and not spend much on roaming charges. All this is set to change. 

The opposition

After much pressure and huge delays, the Department of Telecommunications has finally announced that it intends to introduce free roaming for all mobile phone users by October this year. While this is a welcome move for all phone users who end up paying a fair share of their mobile bills as roaming charges, major service providers are opposing this introduction fearing loss of revenues. Introduction of free roaming is meeting strong opposition from telecom majors such as Airtel and Vodafone, who do not wish to lose such a large share of their income to the government’s decision. If enforced, these companies aim to recover revenue losses by increasing base tariff for all costumers, which would be unfair to bulk of the users who rarely using roaming facilities. Instead, both these players recommend the introduction of fixed price vouchers, just like SMS packs, ISD packs, that will allow users to enjoy free roaming for limited period of time. So, consumers who travel often can opt for these packs and enjoy free roaming while outside their home circles, without affecting the regular users in the circle. While this may seem like a win-win situation for telecom companies and users, it does fall flat on the government Telecom Policy. 

The opportunist 

Anil Ambani led Reliance - Reliance Communications though has quite a welcome approach to this government directive. Taking a leaf from similar policies implemented abroad, especially, the US, Reliance Communications believes that availability of free roaming will further boost telephone calls between roaming users and their home circles. This will increase average expenditure per user, which could make up for the losses companies might face if roaming charges are abolished. 

The present situation

Whether, these policies will affect dual SIM technology, depends largely on the number of users who use SIM cards from different circles on their dual-SIM compatible phones.  Dual SIM phones are also gaining popularity since they allow users to get maximum benefit out of a company’s offer for text messages and/ or data packs. As long as users stick such usage, Dual SIM technology is here to stay. Also, there are many users who opt to keep their business and personal life separate at all times. A few years ago, these were the people you would see carrying two-three phones at a time. With dual-SIM phones, it is now a rare sight to find someone carrying multiple phones. Such users take advantage of dual-SIM functionality to keep their personal and business life separate. You could be on vacation and still be reachable for important clients or choose to respond only to emergency situations, all thanks to your Dual SIM phone. 

Also, certain far-off areas such as agricultural fields, industrial areas do not have the privilege of multiple service providers. Hardly one or two service carriers connect these far off areas. People usually traveling to such areas regularly while residing elsewhere in the town or city tend to use dual-SIM phones to stay connected at all times. This is another set of users that will still continue to use Dual SIM Phones. 

The real dilemma 

As October approaches, the story of free roaming will slowly unfold. Whether the Government bows down to pressure from the service providers or stays committed to its announcement will only be known when October arrives. The introduction of Free Roaming will also bring about a much need unification of network circles. Whether it will kill Dual SIM technology or not, only time will tell, but unification of network circles and availability of mobile-number portability (MNP –meaning, the mobile number you are currently using might be the only one you will ever need) are a much welcome change. Again only time will tell whether or not these changes are here to stay.  It remains to see how Dual sim technology breaks into the Top 5 Trends in mobile industry.

Computer System and Network Security Management

Many of the critical security problems are caused by computer systems. The weaker security measures on a computer system can invite attackers to run malicious code on it. Very carefully follow the security policies and make sure that a new computer system is secure before you link it to a network. The security management tasks to be performed on a computer system may include the following:

• Install an operating system by using a secured file system.
• Create user accounts and assign privileges to the users based on the security policies.
• Use strong passwords for the user accounts.
• Remove the unused and unnecessary user accounts including the unnecessary default accounts and guest accounts.
• Turn off the unused and unnecessary services such as Telnet and anonymous access.
• Turn on the automatic security service.
• Restrict the access to the shared files, folders, and disks.
• Set the account lockout policy.
• Install the latest security packs, patches, and antivirus software.
• Distribute the latest security packs, patches, and antivirus software to students and faculty members.
•  Enable the security event auditing service and the log warning service.
• After the installation of a software package or a new hardware device, run security assessment software to see if there is security vulnerability. Not only do network administrators need to carefully enforce these security measures, users including students and faculty members also need to do the same. A list of security measure enforcement tasks should be available to everyone who is involved in an online computer lab project. Fix all the problems before you link computers to a network.

Network System Security Management

A network is another most vulnerable place that can cause disastrous damage. Once the network is infected, all the computers and network devices connected to the network will be affected. Extra  caution needs to be taken before the network is deployed and used by the public.

• Install the latest patches on routers and switches.
• Enable the security filters, monitoring service, notification service, and auditing service.
• Disable the unused services.
• Use strong passwords.
• Block all the vulnerable ports.
• Secure routers and switches.
• Encrypt the network traffic.
• Block the unused protocols by default.
• Configure the network not to receive or forward broadcast messages.
• Enable the firewall and configure it according to the security policies.
• Update the firewall with the latest patches.
• Enable IPsec on the firewall and configure it for encrypted communication.
• After the network equipment is installed, run security assessment software to see if there is security vulnerability.

The network security measures should be fully enforced while creating the network. Most of these tasks should be done by network administrators who have the security management experience and the knowledge.

Building A Computer Network

When you are looking to build new computer networks there are things that you must look out for and there are electrical supplies that you must have. Some of the things you will need are:

The first step you will undertake is designing the whole network so that you may have an idea of what you will need and how you will go about the process. This process includes the design estimate of what will be needed in terms of the voltage that will be needed, the voltage losses, a protection line in the event that a short circuit occurs, the supply mains that will be used must be checked that they will not overheat and if they will, more are installed or they are changed. The design process will also involve calculating and choosing the protective cut-out devices (PCDs) that will be used, current time characteristics of those protective devices, the earthing system calculation and the labour involved and the amount of time that the work will take.

Then there is the wiring stage where you will need to implement the design you have come up with. It is important to use quality materials and to use certified personnel for this part of the job so that your network system can last for long and you will not have your equipment and computers damaged by sub standard work which can prove to be very costly. You may also think about putting a standby generator or power supply so that when there is a power outage or power is interrupted, your machines are still running and you have a constant uninterrupted power supply. This is especially best for industries that are crucial such as medical facilities, emergency facilities and other similar operations.

If you are want to network all the computers in your home or in a small business setting then you can use power line networking as it is cheap since it uses the electrical wiring that already exists. You may also opt to use wireless routers if you are a small outfit. If you are doing a simple connection in your home, you can do the networking by yourself without getting a professional to do it. It is simple and as long as you follow the instructions, you will be able to do it. Put the router in a central room and then plug it in and turn it on. If you are connecting a shared internet connection then connect the Ethernet cord into the internet port on the modem and then to the computer, the associate lights should go on.

Put on your computer and then run the operating system's network configuration program depending on the system that you are using. Follow the instructions on the installation wizard and you will be able to network all computers so that you can share internet access, files and the printer. If you are looking to install for a large network then you ay need the services of a professional to do it correctly.
