Wireless Mess Network #2

The first wireless mesh networks were mobile ad hoc networks – with wireless stations moving around and participating in a peer to peer network. Mesh is an attractive approach for wireless networking since wireless nodes may be mobile and it is common for a wireless node to participate in a network without being able to hear all of the other nodes in the network. Mobile peer to peer networks benefit from the sparse connectivity requirements of the mesh architecture; and the combination of wireless and mesh can provide a reliable network with a great deal of flexibility. The popularity of Wi-Fi has generated a lot of interest in developing wireless networks that support Wi-Fi access across very large areas. Large coverage access points (AP) are available for these scenarios, but the cost of deploying these wide area Wi-Fi systems is dominated by the cost of the network required to interconnect the APs and connect them to the Internet— the backhaul network. Even with fewer APs, it is v

Capacity of Wireless Mesh Networks Understanding Single Radio, Dual Radio and Multi-Radio Wireless Mesh Networks This post not a tutorial, just sharing knowledge about Wireless Mesh Network from many reference we have and from our experience on the field as a wireless internet sevice provider and computer network consultant. We focuses on wireless mesh infrastructure systems used for creating large Wi-Fi access networks, and examines three different approaches currently available for implementing them. It examines the strengths and weaknesses of each approach with a particular focus on the capacity that is available to users. Can wireless mesh infrastructure systems deliver enough capacity to support broadband services for a large number of users? Mesh is a type of network architecture. Originally, Ethernet was a shared bus topology in which every node tapped into a common cable that carried all transmissions from all nodes. In bus networks, any node on the network hears all tr

Free Portable Applications - The Best

A Portable Application is a computer software program that is able to run independently from  a hard drive, USB drive, or an iPod, without the need to install any files into the system. By using portable applications, you can take your “computer setup” with you, keeping all your favorite software in one suite. That’s a more intelligent approach than trying instead to minimize the number of programs you install, so their installation can be recreated on another device. There are thousands of portable applications available, many of them are versions of installable programs. Using the list below, you can build a very powerful suite with the best of the best portable apps for different software categories: Free Portable Anonymous Surfing Browser: xB Browser — Download “A portable version of Firefox with a well integrated Tor engine that uses the free Tor network. It’s easy to setup and doesn’t require advanced knowledge, but you will have to use it as a second browser for anonym

UberTwitter was Suspended by Twitter

Suspended since about 11 hours ago and in 4 hours after, UberMedia CEO already makes some movement to fix it, what a fast reaction *amazed*. UberTwitter now called UberSocial. Here is a Q&A from Bill Gross , Founder and CEO of UberMedia Twitter told us today that they suspended our applications for three reasons: Twitter said that in UberTwitter and Twidroyd we use a tweet-elongation service named tmi.me that allows people to write more than 140 characters, and that this service may post private messages on a public website.  At their request, we have removed this ability. Twitter said that in UberCurrent we change links that are part of an affiliate program to be our own links.  We don’t currently do this, but we removed all changing of links to eliminate any possibility of this. Twitter said that they would like us to change the name UberTwitter, and we have changed the name to UberSocial, effective immediately. Twitter also said that as soon as we made these cha
