Femtocell – un router GSM

Chiar daca semnalul GSM nu mai este asa o problema ca acum cativa ani, si antenele operatorilor se inalta de pe orice colt de bloc, semnalul nu este suficient de puternic pentru a penetra in toate cladirile. Fie din cauza peretilor prea grosi, fie datorita interferentelor cu celelalte dispozitive electronice, cand suntem in casa, avem parte de conversatii de calitate scazuta la mobil.
Ori sunt pierderi de semnal, ori se aude mai prost, cu artefacte auditive si tot asa. Insa operatorii de telefonie mobila au gasit solutia. Nu va bucurati inca totusi! Pentru ca rezolvarea lor nu tine de un semnal mai puternic sau ceva de care sa profitam pasiv.Ei au inventat un nou dispozitiv, denumit femtocell (inca asteptam traducerea in romana de la organismele autorizate).
Acesta este un fel de router personal, pentru semnalul GSM. Si poate fi cumparat si instalat in casa, pentru a imbunatati receptia. In plus, permite conversatiile directe intre doi utilizatori din aria sa de acoperire, fara a mai trimite la satelit si inapoi semnalul.
Dar cuvatul cheie aici este “cumparat”. Pentru ca un astfel de femtocell are un pret de 200 $. Deci ar trebui sa platim destul de mult pentru ceva ce intra in sfera operatorilor. In SUA, companiile de telefonie mobila vor subventiona aceste dispozitive, ajungandu-se la un pret de aproximativ 50 $. In plus, pentru alti 15 $ la abonament, utilizatorii aceluiasi femocell vor putea vorbi gratis intre ei.

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...
