Abstract

Until now the use of the internet disuatu agencies viewed from the initial planning, use and care, even long-term planning is still not optimal. The main factor lies in the existing human resources, especially in IT personnel and policy makers who do not understand or do not even know at all how your use of the Internet well, optimal, efficient, particularly associated with the consumption of Internet bandwidth. Internet bandwidth capacity greatly affect the speed of web access or other Internet applications. So we need a plan and maintance necessary to obtain good Internet bandwidth consumption efficiency and guaranteed QoS, such as by utilizing Tproxy and filtering methods. TProxy is a development of which has been patched Squid, a proxy to be able to pass traffic without NAT (Network Access Translation). Fitering a firewall system which is used for filtering data packets that do not want filtered dikendaki or akhirmya able to minimize traffic on bandwidth usage. Tproxy and filtering runs on the Linux platform. Linux distributions are often used to Tproxy is a variant Debian, Centos and then to use Mikrotik Filtering. At the end of each request or query from the client or the response of the proxy server does not have meaningful constraints, the bandwidth between the client and the proxy server does not happen limitation, bandwidth capable of running close to capacity including 10 Mbps Ethernet, 100 Mbps, and even a GPS (full speed).

Abstract

As a result of the release of ISM 2.4 GHz frequency for use in the field of wireless data communication through the media and the lack of clarity about the rules in the use of a frequency of 2.4 GHz to be one factor interference in wireless communication. Interference generally occurs in urban areas the level of use of wireless data communication through the media is very high. Wireless devices 2.4 GHz are easily available and inexpensive, making the user media data communications using wireless LAN as a cheap alternative compared to other data communication media, such as Fiber Optic, Radio Microwave Link.It is in fact the channel that is used in 2.4 GHz wireless communication is permitted only 11 channels starting from 2412Mhz-2462Mhz frequency, as more users make a frequency of 2.4 GHz increasingly crowded existing channels, resulting in wide bandwidth of each channel is also increasingly cramped. The width of the narrow bandwidth that clearly affects the quality of the process data communication, data sent or received experienced loss.One quick method to overcome these problems is to utilize the capabilities of wireless devices Superchannel. One of the wireless devices with Atheros AR5413 chipset which has a mini-PCI Superchannel is R52H which is the product of mikrotik. Superchannel frequency range starting from 2192Mhz - 2539Mhz. Indeed, in the frequency range is still illegal superchannel for some countries, like Indonesia, but many Internet access providers, or ISPs use this superchannel capabilities for data communication media, both for distribution to customers or to the ISP backbone network, although not used permanently.
