Adoptarea 802.11n va declansa noi tendinte in 2008

In 2008 retelele wireless pentru companii se vor re-inventa, cel putin pentru cele care mobilitatea este o necesitate, nu doar o solutie la moda.Schimbarile sunt produse de disponibilitatea echipamentelor pentru WLAN bazate pe prototipul al doilea al standardului IEEE 802.11n. Ele pot furniza rate de transfer a datelor de 300Mbps, cu viteze uzuale intre 150 si 180Mbps.Diferentele fata de solutiile conventionale, cu viteze maxime de 54Mbps si rate de transfer efective la jumatate, sunt substantiale, multe companii fiind dispuse sa plateasca in plus pentru astfel de echipamente si sa le foloseasca desi nu sunt pe deplin standardizate, bazandu-se pe premisa ca eventualele neconcordante fata de versiunea finala a 802.11n vor fi corectate prin actualizari de software.Un sondaj efectuat de Colubirs (o companie care comecializeaza astfel de echipamente) in vara anului curent pe 195 de profesionisti IT a aratat ca 44% dintre ei intentioneaza sa faca implementari bazate pe 11n, peste o treime fiind de parere ca ar putea inlocui chiar reteaua cablata pentru conectivitatea cu clientii.Pe langa vitezele de transfer superioare sunt importante si stabilitatea si consistenta conexiunilor, realizate prin tehnlogia antenelor multiple denumita MIMO.Sursa: IDG

Creating A Cheap Bluetooth Sniffer

Many papers and posts on internet forums have commented on the success of turning normal everyday bluetooth USB dongles ($10), into their more powerful counterparts that allow the capturing of packets from the airwaves. These more powerful USB dongles are usually sold at a much higher price ($10,000) together with the software to drive and control these devices. The problems associated with BlueTooth sniffing You cant simply just purchase the dongle with the alternate firmware. There is next to no real opensource packet capture program for the bluetooth protocol. Hardware & Limitations Chipsets: Whats the difference? The chipset of the Bluetooth USB Dongles are very important. Broadcom chipsets are cheap hardware and are deemed unsuitable devices for this paper. But unfortunalty nowadays, every manufacturer seems to prefer putting these chips in their products compared to the more reliable Cambridge Silicon Radio (CSR) chipset. If your lucky enough to find a dongle with a CSR chips...

ALFA-­AWUS036H & ALFA-­AWUS050NH INSTALLING/UPDATING DRIVERS RTL8187, r8187, RT2800usb on UBUNTU

NOTE: For surfing Internet with ALFA-AWUS050NH on Ubuntu Jaunty with rt2870sta driver, you must use the Kernel "2.6.28-11-generic #42-Ubuntu", without change or updates the drivers modules. NOTE: The tutorial is not related to Ubuntu karmic. Driver RTL8187/Stacks-­mac80211 (ref. ALFA-­AWUS036h) ­- These drivers, for surfing Internet, are more stable than r8187, and fully compatible with Network-Manager 0.7 installed by default on Ubuntu 9.04. Network-Manager 0.7 installed by default on Ubuntu 9.04. ­- Supports all encryption without problems. (OPEN, WEP and WPA/WPA2) ­- With Compat-Wireless, the "injection" working, but for support “Fragmentation attack” (opt. -5) you need to install one patch. - The RX sensitivity and packets injection is less, related to drivers r8187. Driver r8187/Stacks-ieee80211 (ref. ALFA-AWUS036h) - This driver is recommended for use with the Suite of Aircrack-ng, but not particularly suitable for Internet connections, as less stable and disc...
