# Smart Phones will play a major part in next generation Mobile Teachnology. The  wearable technology, such as smart watches, and other accessories, is the next big thing. Currently Wearable technology  is \$4- to \$5 billion market and could grow \$30- to \$50 billion. Wearable technology mainly be used on Medical, Sports, Engineering and Education applications. Wearable technology uses computer and advanced electronic technologies uses software, sensors and connectivity to enable objects to exchange data with a manufacturer, operator and/or other connected devices, without requiring human intervention. Wearable technology is related to ubiquitous computing. As an example a patient condition can be monitored by doctor remotely.

### How to redirect your website to its mobile version

Javascript window.location Method

Mobile phones typically have a small screen width. A simple trick is to redirect if the browser width less than or equal to 800 pixels. However when the mobile is horizontal the with can be increased 960 pixels or more. The tabs use larger with will still use the non mobile site.

<script type="text/javascript">
<!--
if (screen.width <= 800) {
window.location = "http://m.shilpasayura.com";
}
//-->
</script>

.htaccess URL rewrite redirects

Based on the MIME types browser support,  .htaccess can redirect visitors

RewriteEngine On
# Check for mime types commonly accepted by mobile devices
RewriteCond %{HTTP_ACCEPT} "text\/vnd\.wap\.wml|application\/vnd\.wap\.xhtml\+xml" [NC]
RewriteCond %{REQUEST_URI} ^/\$
RewriteRule ^ http://m.domain.com%{REQUEST_URI} [R,L]

This can check wap capability for wap apps which are no longer needed with smart phones

CSS3 media queries

Currently this is the best option as you can use different style sheets to render your web site on any device.

<!-- CSS media query on a link element -->

<link rel="stylesheet" media="(max-width: 800px)" href="device800.css" />

<!-- CSS media query within a stylesheet -->
<style>
@media (max-width: 600px) {
.shilpa_sidebar {
display: none;
}
}
</style>

A good method is to seperate general and device specific css into seperate css scafolds.

<style>
/*General CSS here*/
font-family:Arial, "Sans-Serief";
</style>

<style>
@media (max-width: 1300px) {
font-size:16px;
}
</style>

<style>
@media (max-width: 540px) {
font-size:12px;
}
</style>

### Forwarding Ports in a Broadband Router

Broadband routers keep track of all outgoing connections from the LAN side by maintaining an internal mapping table of which computer on the LAN is responsible for a given outgoing connection to a particular destination on the internet.  This allows two-way communication between computers on your LAN and computers on the internet.

When an unsolicited connection comes in from the internet, your router does not know what computer, if any, in the LAN should receive the connection, and will block it.

In order to receive incoming connections from the internet to your computer on the LAN side of the router, you need to change a setting in the router's configuration so that it forwards all incoming connections for a particular port number to your computer in your LAN.
