Topic 1 “Cellular Base station - Femtocell”
Abstract:
In telecommunications, a femtocell is a small cellular base station,
typically designed for use in a home or small business. It connects to the
service provider’s network via broadband (such as DSL or cable); current
designs typically support 2 to 4 active mobile phones in a residential setting,
and 8 to 16 active mobile phones in enterprise settings. A femtocell allows
service providers to extend service coverage indoors, especially where access
would otherwise be limited or unavailable.
For a mobile operator, the attractions of a femtocell are
improvements to both coverage and capacity, especially indoors. Consumers
benefit from improved coverage and potentially better voice quality and battery
life. Depending on the carrier they may also be offered more attractive
tariffs.

Topic 2 “Flash Drive Security Provision by Partition Technique”
Abstract:
The biggest problem faced with the USB Flash Drive is the
security of data and the protection from infected viruses and malware that
corrupt the machines that are connected to it or when comes to data sharing.
The solution for this is now available with features like password protection,
encryption and anti-virus. As of passwords, its database itself is encrypted
and the encrypted database can be kept within the encrypted virtual drive.
In
order to make USB flash drives secure by adding the necessary encryption and
password authentication, manufacturers have added software…and this is the
problem. Software requires drivers and updates, along with being platform
dependent and accessible to hackers.
Partitioning the flash drive will create
several partitions similar to that of hard drives in the system. But the main
point is that, the partitions can only be seen on the system which was used to
partition the flash drive. This will protect the data present in the flash
drive from viruses and unauthorized persons.
