People of Mumbai should not lend its technological resources to the cause of crime beacuse the lead protagonist of attacks that have bloodied the capital recently used a wide deployment of technology, the messages of terror are often carried by networks and the are not adequately protected.
Mumbai police are now mobilizing themself to close the connectivity taps left open from individuals, businesses and institutions.
There are 80 agents ready to patrol the streets of Mumbai: trained by security experts, have learned to detect open WiFi networks using laptops, smartphones with every kind of air cards. They will soon be invested with the mission to close all the glimpses of connectivity recklessly made available.

India already has taken security measures to prevent the use of the not identifiable Internet: many Indian states have introduced the requirement to register with documents register citizens who use Internet in order to prevent that the Netcafe be exploited for purposes that are outside the law, Mumbai had predicted that the public Internet workstations must be equipped with systems that allow the police to monitor the online life of users and to reconstruct the navigation paths followed. If the Internet café does not offer a bad basis on which to build their strategies, private individuals, institutions and companies continue to provide bandwidth and anonymity to those who think of use the network as a tool to break the law.

For this reason, the police provide notifications and require passwords to anyone innervated the metropolis of connectivity. “Our men, equipped with laptops, air cards and mobile phones, will make random checks in shopping malls, cinemas and the areas occupied by offices – said a representative of local law enforcement – if they identify a connection not protected they contact you warning that your network could be used by criminals. ”
But India will not only raise awareness of the connectivity by cutting open nets. The security forces are preparing to infiltrate inside criminal organizations using the new version of the local law against cyber-crime. If they are softened the penalties for those who are guilty of crimes mediated by technology, is also given them by law the ability to monitor all communications that running online.

After about a year and a half of work, Bluetooth Special Interest Group (SIG) now seems close to the specification published Alternate MAC / PHY, which combine the advantages of Bluetooth such as the ability to rapidly establish connections peer (P2P) between multiple devices, with the high-speed data transfer of WiFi air cards.

To maximize battery life, the new specification requires WiFi to be used only when really necessary, for example, to transfer large files or to stream multimedia content. In practice, therefore, devices capable of supporting the new standard will continue to find and connect with each other using Bluetooth air cards: As soon as users start a transfer or playback of streaming content, the communication is passed to layer 802.11b / g, that will transfer data at maximum speed of 54 Mbps (802.11n support is likely to be added in future). Once the transfer or streaming is finished, WiFi is disconnected and the control returns to Bluetooth.

Bluetooth SIG says that Alternate MAC / PHY can be used, for example, to synchronize your library of music between PC and MP3 player, print photos directly from a camera or a TV to send a video stored on a mobile device.

The most interesting is that, as explained by a manager at Broadcom, some of its wireless chip already support Alternate MAC / PHY This suggests that some mobile devices on the market today can make use of the symbiosis between Bluetooth and WiFi with a simple firmware upgrade or the system software without the helping of any aircard.

The specific functionality provided by the Alternate MAC / PHY are made possible by the service Service Discovery Protocol of Bluetooth, which is able to negotiate with other wireless network protocols.

Being a sort of intermediary protocol, Bluetooth making it possible interoperability between different wireless technologies, significantly simplifying the communication between mobile devices. Some observers argue, however, that it would be more positive if the market converged toward a single standard, or at most two: the coexistence of several wireless technologies, although each optimized for a certain field of use, multiplies the radio circuits and integrated into aircards, consequently, their cost, their size and their energy consumption.
