The two most popular wireless technologies (wireless) are the Bluetooth and WLAN (wireless local area networks) that means something like “wireless LAN” and is more commonly known as WiFi .
These technologies have proven to provide additional means wireless access to various applications.
Bluetooth is a wireless personal area network (PAN, personal area network) technology, which allows for short distances, the transfer of data between devices. Allows, for example, replace the USB cables between computers and peripherals, data synchronization for PDAs, wireless headsets and headphones, not to mention mobile phones and now the whole paraphernalia of a “toy” that comes with this technology incorporated.

In comparison, the WLAN technology, works as a replacement for an Ethernet cable, allowing the rapid transfer of data over much longer distances, creating wireless networks for data transmission, video and voice over IP (VoIP). In addition to home and installed in the office, Wi-Fi has grown recently with the installation of hotspots (access points) public. For example in airports, shopping centers, universities, etc. Does one really need a platform for mobile games have success? No, especially if it is as curious as that of WiFi Army, created for Android, the Google platform.

Lately we have seen the increase in supply of equipment with operating system Windows Mobile. Each day there are more brands and models, form factors (shapes), screens with different sizes and resolution, input options and diverse interaction, support for more wireless standards, different storage capacities, all combined with either distinguishing feature in some models. To help you in your choice, we introduce you to each feature on the options you can find, so they can make an informed choice. In the section of the equipment can then find a selection of equipment available in Portugal, where you can view the features of each item.

Development of WiFi technology

WiFi networks follow the 802.11 standard developed by IEEE (Institute of Electrical and Electronics Engineers) and approved in 1997, which is widely accepted by the international community. At the time of drafting the standard WiFi networks operate using the 2.4GHz frequency, which is license-free, and allowed a maximum bandwidth between 1 and 2Mbps. More recently, in 1999, approved the 802.11b and 802.11a standards, using frequencies of 2.4 GHz and 5 GHz and can achieve 11Mbps to 54Mbps, respectively.

Currently the most widely used standard is 802.11g which has the same specifications of the 802.11b standard, but offers speeds up to 54Mbps. There are several promising areas of standardization such as 802.11n is in final approval and will have their bandwidth reaching up to 104Mbps operating in the 2.4 GHz (free) and 5GHz (licensed). Some companies including Cisco, released a proposal for the IEEE 802.11s mesh networking specific you want to standardize the routing protocols and management of a mesh network. As defined by Professor Celio Vinicius Neves Albuquerque (UFF) Mesh networks are “wireless mesh networks that interconnect self-configuring a set of fixed nodes are able to route packets between them.”

Usually the nodes and network routers use technology WiMesh 802.11 Ad-hoc mode, where the access nodes to communicate without the need for a central AP controlling all communication, creating a mesh asim wireless data with low cost of deployment not due to the need for prior establishment of an infrastructure. Wireless networks increasingly have had an increasing involvement in our lives and many technologies have been created to explore this. Expected to have achieved the goal of making it easier to understand the operation of networks WiMesh, although not the intention of this material as a guide, but dilute, for academics and others associated with deploying and maintaining networks, the quest for technology that best fits your needs.

Looking for a better way Access the Internet using your Wi-Fi connection? The Toshiba Folio 100 may be the answer! The Folio 100 is Toshiba’s answer to the Apple iPod. While falling short of the iPad in many respects the price tag of about half of what it costs to buy an iPad does make up for some the minor short comings.
The Toshiba Folio 100 is more than just an eReader. This is a full hand held computer with onboard Wi-Fi (802.11), eMail and browser capabilities and full multimedia features.
It was very easy to connect the Folio 100 up to my network and some of the newer models even have the capability to use a SIMMs card to connect to an IP directly. I have found that the page load of the Folio is a bit slower than my laptop, but not enough to be an irritant.
One of the best features of the Folio 100 in respects to internet browsing is its voice recognition ability. Typing search words into the Google search bar works well with the touch screen keypad but the easiest way is to click the voice program button and simply state what you want in the search bar. So far I have been very impressed with the Folios ability to recognize spoken words. If there is any question it gives you a list of possibilities that you can quickly choose from.
The voice recognition also works for imputing data into test boxes. Click on the box, press the microphone button, state what you want in the box and it is added in automatically. Much easier that typing on the touch screen.
I also appreciate the ability to use the touch screen to zoom in on web page details. It even works very well with Google maps. The screen is bright and clear making it easy to read.
The Toshiba Folio 100. If you are in the market for an eReader or hand held tablet computer it’s well worth checking out the Toshiba Folio 100 Specifications before you spring for the much higher priced Apple iPad
