VOIP pe telefoanele mobile

Programele de telefonie prin Internet (bazate pe tehnologia VOIP) investesc tot mai multi bani in crearea de software-uri destinate telefoanelor mobile. Astfel, folosind retelele GPRS, EDGE si 3G, utilizatorii pot beneficia de tarife scazute la convorbirile internationale sau chiar de apeluri gratuite. Aceste software-uri se pot instala pe telefoanele dotate cu un sistem propriu de operare, precum Windows Mobile sau Symbian, conexiunea la Internet fiind realizata prin reteaua GPRS, EDGE sau 3G a companiei de telefonie, utilizatorul urmand sa plateasca o serie de costuri suplimentare generate de traficul mobil de date. Una dintre solutiile destinate telefoanelor mobile este aplicatia Fring (http://www.fring.com/), care poate fi utilizata de toti cei care au un cont (si credit disponibil!) Skype. Programul este disponibil atat pentru telefoanele cu Windows Mobile, cat si pe cele cu Symbian. Utilizatorul descarca si instaleaza pe mobil programul, dupa care in "setari" introduce numele de utilizator si parola contului Skype si telefonul este gata sa efectueze apeluri la preturi reduse, precum 0,017 eurocenti/minut (plus o taxa de conectare de 3 centi la fiecare apel initiat). Cei care beneficiaza de sistemul de operare mobil de la Microsoft pot instala direct Skype Mobile (http://www.skype.com/).

Costul pentru un apel scade la jumatate, in cazul Orange, daca se activeaza optiunea "Mobile Internet" cu 5MB trafic inclus (1,5 euro), utilizatorul va beneficia si de un tarif redus/MB dupa consumarea celor inclusi in abonament, de 30 eurocenti. Am testat programul Fring, folosing un Nokia N70ME (cu Symbian). Pentru un apel de 10 minute s-au consumat aproximativ 0,6 MB. Presupunand ca lunar vorbim 200 de minute, vom avea nevoie de 12 MB, care ne costa 5,1 euro. Pentru un minut de convorbire internationala catre o tara UE, America, Canada si altele, in cazul apelarii unei linii fixe, pretul final este 4,5 eurocenti/minut. Clientii Vodafone si Cosmote platesc 0,3 dolari/MB, respectiv 0,8 euro/MB si 0,3 euro/MB (abonamente cu transfer inclus).

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...
