Wireless technology that eliminates the need for wires and cables, and facilitates access to information in the easiest manner possible, is here to stay. It is being used in mobile phones, video games, home networks. Every personal computer operating system and game console supports Wi-Fi.
With so many advantages that it affords, it is no surprise that people overlook any drawbacks it may have, such as the security issues. Wi-Fi networks that are unencrypted or open can be easily monitored by others and used to view all the personal information transmitted over the network, unless some sort of security, such as a VPN or a secure web page is used.
In order to protect people’s interests and make them aware of the security aspect of Wi-Fi networks, the FBI has recently issued a warning that the Wi-Fi hotspots or the wireless internet networks are easy prey to hackers.
These wireless internet networks are found at airports, book stores, malls, supermarkets, school campuses, coffee shops and several such places. These networks are installed for the use of residents of different localities; however, security at these places is very low, with no registration or passwords required to use the service. Even emails and instant messages are not encrypted.
This sort of a setting is like a full-fledged feast to a hacker, who can access and steal this private information from anywhere in the world. Continue Reading →

The Role Of Wi-Fi Devices As Lifesavers!
04 June 2008no responsesHasan
Wireless technology has changed the face of communication and with the creation of Bluetooth; people felt they have seen it all.
However, the quintessential mobile has just become more endearing and turned our savior. From now on, it will also call the doctor in case of an emergency and its owner is unwell.
Latest research shows that the mobile technology has been given the capability to call the doctor when the owner of the phone is in danger. This works for patients with chronic health problems, such as people who are at risk for a diabetic collapse or a heart attack. With sensors implanted inside the bodies of such people, doctors will be able to monitor them remotely.
If the “in-body network” of sensors recorded that the person had suddenly collapsed, then an alert would be automatically sent to a surgery or a hospital nearby. These network sensors monitor the patients’ moves and pick up health signs that can prove to be dangerous, such as high blood sugar levels or an attack of asthma, and send an alert via a portable monitor or a home hub.
This research is being carried out at Portsmouth as well as many universities in the UK.
They say that these networks may use a spectrum that is allotted to be used by these sensor networks. The main belief behind this technology is that radio spectrum can be used in many ways to help people. Continue Reading →
