VoIP and Its Increasing Impact on Mobile Networks

Posted by on Friday, 17 December, 2010 No comments

A report released in mid 2010 analyzed the impact of mobile VoIP on next gen cellular networks. Both mobile and wireless industry has unbelievable growth expectations as this technology becomes more accessible, whether through WiFi or 3G and 4G networks.

The question is, can voip wireless phone actually fulfill customer’s expectation for saving, or will mobile carriers carry on to block access to technology that many people think that it is an almost free of charge wireless solution?

The adoption of VoIP for mobile by some telecommunication leaders has effected the growth of better availability, better quality audio, and faster data connection. However, Flat rate mobile pricing continues to change wildly and each mobile start-up has its own restrictions and deals designed to get the most out of each client.

IP is expected to become the primary transport for future data access, and carriers are being forced to accept the fact that mobile VoIP will be the key player in integrated IP-based communications and also next gen wireless processes.

While smartphone vendors are including applications so users can download and use third-party VoIP clients over WiFi and broadband networks, many cellular operators keep on to prohibit the use of wireless voip on their cellular networks, or force hefty surcharges.

The primary argument that mobile operators use to fight the cost effective lure of VoIP is the claim that VoIP used on the cellular networks can’t offer good quality, reliability, and efficiency compared to that supplied by GSM network. 60% of European mobile operators restrict or prohibit the usage of VoIP on their mobile data plans, and the US is also no much better.

However, while high definition voice have become standard on all smartphones, the argument that mobile IP communications is udner standard will cease to hold water., Even though mobile carriers can be expected to keep on trying toblock access where possible, mobile VoIP is here to stay.

6 Reasons Why You Should Recycle Your Cellular Phones

cell phone recycling 224x300 6 Reasons Why You Should Recycle Your Cellular PhonesSome Not-So-Fun Facts

Cell Phones are environmental hazards! If not disposed of properly cell phones are damaging to our air, soil, and water:

1. One cell phone can pollute up to 132,000 liters of water.
2. Cell phones (and other electronic devices) contain toxic substances such as arsenic, lead, cadmium, and beryllium that can pollute the air when burned in incinerators and leach into soil and drinking water when buried in landfills.
3. Cadmium can damage the kidneys and it is transferred through the air and through our food.
4. Lead accumulates in landfills and can cause damage to the central and peripheral nervous systems.
5. Mercury gets into our water supply and accumulates in living organisms and travels up the food chain. The principle exposure pathway is through our food and it causes braid damage.
6. Cell phone recycle campaigns are good for our environment because all collected cell phones and electronic devices are either refurbished or disposed of using only the most ecologically sound methods.
Here’s a great idea. Why not take those used & unused wireless devices lying around in some box at your home of office and recycle them to the benefit of the environment and a selected Not-For-Profit (NFP) who needs your help. A little ‘GREEN’ initiative can go a long way.

This is how your mobile phone donation can help!

If only 10% of 5,000 donors send in just one cell phone… that would be 500 basic mobile devices at approximately $2.50 per device to the benefit of the selected NFP… which would equal $1,250.
Let’s say 10% of the devices where BlackBerry’s or smart phones… that would be 50 devices at approximately $20 a device and the NFP would receive… $1,000
Combined that would be $2,250 for this one major effort!

cell phone first History of Cellular Phones Part 1Cellular: A type of wireless communication that is most familiar to mobile phones users. It’s called ‘cellular’ because the system uses many base stations to divide a service area into multiple ‘cells’. Cellular calls are transferred from base station to base station as a user travels from cell to cell. – definition from the Wireless Advisor Glossary.

The basic concept of cellular phones began in 1947, when researchers looked at crude mobile (car) phones and realized that by using small cells (range of service area) with frequency reuse they could increase the traffic capacity of mobile phones substantially. However at that time, the technology to do so was nonexistent.
