Design and Research - General Wireless Properties

Hello all,

First of all I would like to apologize for not updating the blog for so long, but being honest, I was literally too busy in researching and studying the related information.
I have tried extracting much relevant information as I could to explain the concept to anyone from a scratch.

Starting with Wireless Technology

What is it ?
How does it influence our daily lives ?
What are the possibilities ?
How far have we come and how further can we get with it ?
.... and lot more

Well, Wireless Communication, in a simple language is anything that exchanges information without any physical medium of transport between them. For instance, cell phones, Bluetooth, TV remote and so on. If we look around, practically everything we see has turned wireless now.
Skipping directly to the technicality and nature of wireless, I would like to start with talking about some common wireless technology and their general properties

• Wireless Personal-Area Network (WPAN) 
• This type of network usually belongs to an individual or for group of people working in a small room.
• Enables exchange of data in small range.
• Example :Bluetooth -

• Follows IEEE 802.15 standard
• Signals can travel up to 100 m range.
• Speed up to 24Mbits/second.

• Wireless LAN (WLAN)
• This type of network is suitable for an building, office, company or home for internet access and exchanging information, in fact this is the most common and reliable mode of internet access these days due to its mobility and excellent throughput. 
• Example: Wi-Fi ( Wireless Fidelity) -

• Follows IEEE 802.11 standard
• Commonly ranges up to 300 m.
• Application : All devices for instance in a building are connected to the wireless Access Points and if someone wants to print a document from front reception to the printer located at 3rd floor, the front desk computer will send the information to the wireless access point which will then froward it to the central router and then router will look up for the destination printer and will send the document for printing to it.

  Wireless Router and devices connected to it

• A special Wireless NIC (Network Interface Card) must be installed in the host devices to access the wireless network.

• Wireless Wide-Area Network (WWAN)
• This type of network is generally used in cellular phones and pagers to access the mobile network (GSM/ LTE/ CDMA)
• Commonly ranges for few Kms.
• Uses Satellite and Radio Towers as mode of Network Access.
• Example: Worldwide  Interoperability for Mocrowave Access (WiMax) -

• Follows 802.16 standard
• It is WiFi on large scale to cover a wider area to provide network/ internet access to clients and uses special high range broadcasting Access Points(unidirectional and/or omnidirectional) for broadcasting.

Thank you all for reading this, more updates are coming soon talking about Radio Frequencies, Standards, WiFi certification, and much more. =)
