Facts About Wi-Fi Technology


Wi-Fi essentially is the technology that enables you to transmit information, images without the need for wires or VGA cables. It is the best option that enables you to get access to data of all kinds as well as images, videos without the need to put in place cabling, wiring, connectors and other paraphernalia normally associated with a wired service.

How does it work?

Wi-Fi makes use of a technology called as IEEE 802.11a or 802.11b. This means that speeds of 11Mbps or 54 Mbps can be harnessed as the network operates in a radio band that is unlicensed. This is the 2.4 – 5 GHz radio band.
This technology facilitates transmission of data almost ten times quicker than Bluetooth and has a much wider range as well. The technology enables you to connect many computers to each other seamlessly and with appropriate security. You can also use it to connect them to other wired networks.

What would you need to put in place a good Wi-Fi network?

The essential elements are an access point that is typically in the form of a LAN receiver and is also referred to as the base station. You then have Wi-Fi cards that can easily accept as well as relay signals. These cards can be fixed internally or externally to a laptop or desktop respectively. Certain safety features like firewalls as well as anti-virus programs need to be installed so that hackers are not able to get into the system and cause damage.

What are the limitations or disadvantages of this system?

Firstly, you could experience some interference in the airwaves that could reduce the performance levels. Secondly, the power consumption is much higher and that could push up your maintenance or operating costs. The limited range could also be something that may not appeal to many users.

However, considering that any Wi-Fi enabled gadgets like the PC, cell phone, MP3 player and the PDA can be connected to the internet at hotspots, the convenience of this technology is making it very popular. There are many hotspots that are being created by establishments like malls, cafes, restaurants, airports and other such public places so that users can do their work on the internet and do not have to depend on a wired connection.

It therefore appears that Wi-Fi technology will only become more and more popular in the coming years.

iPhone Security features

How to Set up a secure email for your iPhone
By default, your iPhone use SSL (Secure Sockets Layer) encryption for, IMAP, POP, e-mail and SMTP; SSL e-mail connections work same as secure web sessions:  iPhone’s e-mail software connections exchanges digital certificate information through the mail server, this creates an encrypted channel which can’t be broken even if using any well-known techniques. For, Gmail, Mac, Yahoo Mail and AOL accounts, which you have set up from your mail screen, SSL is set as the default option which shouldn’t be changed. But remember that you will not get this security when you login to your account through your web-mail interface at Safari. Mac and Yahoo unfortunately don’t provide SSL-protected web-mail access. Gmail offers, but make sure to use https://mail.google.com when you access it, gmail.com won’t work.

For additional accounts to the four service providers, you’ll have to confirm with your ISP to check if it’s supported by SSL connections. But if the ISP doesn’t offer you with a secure option, then you can work through this problem by simply setting the e-mail account to copy all incoming messages or forward automatically to secure service such as Hushmail (www.hushmail.com). Thereafter you can have a mail account set on you iPhone in order to retrieve your e-mails from Hushmail with complete confidence.

How to browse web securely on your iPhone
Even though Apple offers a few options meant for protecting different kinds of web traffic, regrettable not any of them are perfect. Set up secure web proxies one of the option is to use a secure web proxy service, like Secure-Tunnel (www.secure-tunnel.com). This secure proxy creates a SSL connection among the Secure-Tunnel’s servers and your browser representation your session’s unreachable to local Wi-Fi network snoopers. When you want to setup a secure proxy for your web access, and then go to your settings: Network: Wi-Fi. Regrettably, the setting only works on a per-connection basis. You will need to reenter the identical proxy data drearily every single time you have to connect to different networks, making it a somewhat impractical solution with most users. Use a VPN Another option you can use is a VPN. VPNs cover every data leaving an entering operating system on the network this includes, web data, widget communications and e-mail in a strong encryption.

Two popular software are supported by Apple for VPN client: these two are L2TP and PPTP (Point-to-Point Tunneling Protocol), frequently known as IPsec (IP Security) over L2TP (Level 2 Tunneling Protocol).regrettably, if the company requires you to the use your ISP this uses an unique port for the secure e-mail, you will be able to set the iPhone’s Mail program to accommodate this (Port numbers just like numbered cubbies in the mailroom: every cubby corresponds with a particular service, such as, FTP, chat or e-mail.) To have your account set up, click on Settings the Mail and Other. Instead of entering only a mail server address for example, pop.gmail.com, obtain the port number and a colon, like this: pop.gmail.com:995.
