5 Pen PC Technology
P-ISM (“Pen-style Personal Networking
Gadget Package”), which is nothing but the new discovery, which is under
developing, stage by NEC Corporation. 5 Pen PC Technology is a gadget package including five functions: a pen-style
cellular phone with a handwriting data input function, virtual keyboard, a very
small projector, camera scanner, and personal ID key with cashless pass
function. 5 Pen PC Technology are
connected with one another through short-range wireless technology. The whole set
is also connected to the Internet through the cellular phone function. This
personal gadget in a minimalist pen style enables the ultimate ubiquitous
computing.
In fact, no-one expects much activity on 802.11n
installations until the middle of 2008. “Rolling out 802.11n would mean a big
upgrade for customers who already have full Wi-Fi coverage, and would be a
complex add-on to existing wired networks, for those who haven't. Bluetooth is
widely used because we can able to transfer data or make connections without
wires. 5 Pen PC Technology is very effective because we can
able to connect whenever we need without having wires. 5 Pen PC
Technology are used at the frequency band of 2.4 GHz ISM (although
they use different access mechanisms). Blue tooth mechanism is used for
exchanging signal status information between two devices.
5 Pen PC
Technology techniques have been developed that do not require
communication between the two devices (such as Blue tooth's Adaptive Frequency
Hopping), the most efficient and comprehensive solution for the most serious
problems can be accomplished by silicon vendors. They can implement information
exchange capabilities within the designs of the Blue tooth. The circuit diagram
for the 802.11B/G is given below. It is nothing but also type of Blue tooth.
Using this connectivity we can also connect it with the internet and can access
it anywhere in the world.
