Cricket Communications is began selling new messaging mobile phone, namely Cricket MSGM8 II (message mate two). The handset is manufactured by Chinese company, ZTE Corporation.New Cricket MSGM8 II should be replacing previous model, the Cricket MSGM8. The Cricket MSGM8 II can packs a QWERTY keyboard, horizontally oriented TFT display with a resolution of 176 x 220 pixels, 1.3 megapixel camera, Bluetooth, 2.5mm audio connector, a microUSB port, and a 900 mAh battery that provides up to 300 minutes of talk time, up to 250 hours of standby time.The Cricket MSGM8 II phone is designed to work in CDMA2000 1x network. Size of Cricket MSGM8 II is 4.2 x 2.39 x 0.53 inches and weight 3.74 oz (with battery).

You know absolutely that you have switched off your mobile phone before going into the theatre / wedding / class / cinema and nothing could be more surprising or embarrassing than when your ringtone starts playing unexpectedly. In these circumstances it is ironic that most of us will suddenly have difficulty in fumbling for our phone in our pocket or bag and switching if off. Even if in reality we are able to react quickly and efficiently, in our panic it always feels that minutes have elapsed before the first sound and final silence.

So consider how much easier it would be if we only had to move our hand in a gesture in order to silence our phone. That is now becoming possible thanks to a new mobile phone innovation that is being implemented in Germany. Deutsche Telekom has developed software that will allow you to control your phone by moving around a small magnet that can be worn as a ring or attached to your wrist.

The magnet attracts the compass sensor on your phone; and nowadays a large number of smart phone models are equipped with compasses. This new system is continually scans the local magnetic field to see if there are any sudden changes and to establish wheter these changes are the result of deliberate gestures you are making.

For instance, if you are using your phone to read a book or a document, then you can turn the pages by movong your hand from right to left as though you were turning a real page; you can end a phone call by moving your hand sharply in a downwards direction; or you can use gestured to zoom in and zoom out of an image on your screen.

The technology still needs some further development and so far it still makes mistakes; only 90% of gestures achieve their desired results. However the device’s developers are confident that they will overcome their difficulties.

Another area that is receiving attention is the incorporation of touch sensitive pads on various parts of the phone, such as on the back and on the sides. Some of these sensors are becoming so sensitive that they are able to detect the angle of their users’ fingers as they touch the screen, so that different angles can have different meanings.

1G – The first mobile phones were based on what is known as the First Generation, or 1G system. This was an analogue system and was circuit switched. This is a way of creating a connection between devices by setting up a specific communications circuit and keeping it open until the communication is terminated. This system had a number of problems. Often the voice contacts were of poor quality and handover (or handoff) tended to be unreliable so calls could be lost when moving between cells. (Handover is the process of transferring the call between base stations.) The capacity of the 1G networks were very limited. As voice communications were handled by analogue radio signals, listening in to other peoples calls was very easy and could be done with a simple radio receiver – in fact there was no such concept as 1G security.

2G – The somewhat clunky 1G network was replaced by the first digital mobile phone network implementation the 2G, or second generation. 2G networks protocols employed digital encoding. Implementations included GSM, D-AMPS (TDMA) and CDMA:

• GSM was the standard in Europe and is one of the most important ones in the world accounting for 70% of of total digital cellular communications. It uses a time division multiplex (TDM) system over four frequency bands. These are 800 MHz, 900 MHz, 1800 MHz and 1900 MHz.
• D-AMPS (TDMA) is a Time Division Multiple Access digital transmission system which allocates a different time slot on a specific frequency to each individual user. This system is used in the USA, Asia Pacific, Russia and new Zealand.
• CDMA stands for Code Division Multiple Access. This makes simultaneous use of multiple frequencies in a spread spectrum.
  2.5G – The 2.5G system was based on the 2G system but with a few extra bolt-on goodies. In particular it introduced packet-switched connection (GPRS) along with HSCSD and EDGE technologies:
• GPRS stands for General Packet Radio Service which allows packet switching to be which provides more efficient ISP connections. It also allowed for data volume rather than connect time charging so permanent network connection was possible. Data transmission rates of up to 30 Kbps became available.
• HSCSD is high speed circuit switched data which allows data transfer of up to 57.6 Kbps.
• EDGE is Enhanced Data Rates for GSM Evolution which provided data transfer rates of up to 384 Kbps. This makes 2G networks almost as fast as 3G ones.

The one thing that we all want our mobile phones to have is a larger screen, and this concept looks like it is ready to give it.

This is the Flex Display Phone concept, with a 5-inch sliding screen for a lot more room on that screen. it also has a GPS device and a virtual keyboard.

College of southern California experts indicate us a more successful use of graphene photovoltaics

Can you imagine people powering their cell phone or music/video device while jogging on a sunny day?

A University of Southern California team has produced flexible transparent carbon atom films that may have great potential for a new breed of solar cells.

In a paper recently published by the journal ACS Nano, researchers stated that organic photovoltaic (OPV) cells have been proposed as an approach to create cost effective energy due to their ease of manufacture, lightweight, and compatibility with flexible substrates.

The new work indicates that graphene, a highly conductive and highly transparent type of carbon composed of atoms-thick sheets of carbon atoms, has high potential to fill this role. Read the rest of this entry »
