Welcome to the Journey to Science of Complexity, Chaos Theory & Non Linear System Dynamics:

Here is to the crazy ones, the misfits, the rebels, the trouble makers the round pegs in a square hole, the ones who see things differently. They are not fond of rules and they have no respect for the status quo.You can quote them, disagree with them, glorify or vilify them. About the only thing that you can't do is ignore them, because they change things. They push the human race forward, and while some may see them a s crazy ones, we see genius, because the people who are crazy enough to think they can change the world, are the ones who'll do it.

Netsol Technologies ; Netsol Akhter (Netsol Connect) the Broad Band Way

Here is first overview of Broad Band Technology, in order to enable layperson to better understand the hidden potential of Netsol Conect/ Akhter, a subsidiary of Netsol Technologies Ltd. The excellent summary has been prepared by my colleagues:


WIRELESS BROADBAND NETWORKS

Wireless broadband is a fairly new technology combining the two aspects i.e. “wireless” and “broadband”.

Communication channels (paths) are grouped into 2 basic categories- narrow band and broadband, depending on their transmission speeds:

Narrowband or baseband are used for handling low data volumes since they provide low speed transmission rates and hence are adequate for low-speed devices like telegraph lines and low speed terminals. Commonly used for telephone voice communications and for data communications by the modems of PCs and other devices.

Broadband or wideband channels are used when large volumes are to be transmitted at high speed. This data communication system handles high volume of data and can be used for high speed computer to computer communication or for simultaneous transmission of data to several different devices. There are different types of broadband access technologies, such as cable, DSL, powerline, satellite, and wireless.

Data can be transmitted through wired or wireless media. Wireless networks can cover wide geographic areas efficiently. Wireless is being adopted for many applications: to connect computers, to allow remote monitoring and data acquisition, and to provide a solution for environments where wires may not be the best solution. Wireless systems are typically slower than land-based, wire-line networks.

Broadband Wireless (BW)

Broadband means 'having instantaneous bandwidth’. This means that Wireless Broadband offers speeds roughly equivalent to wired broadband, such as that of DSL or a cable modem.

BW is an emerging wireless technology that allows simultaneous wireless delivery of voice, data, and video. It provides high-speed wireless internet and data network access over large distances. BW is considered a competing technology with Digital Subscriber Line (DSL). It is generally implemented in metropolitan areas and requires clear line of sight between the transmitter and the receiving end. What is "high" speed is always a changing number.

Through BW, networks of varying sizes can be deployed in places where it would be expensive to run wires. Because trenches do not have to be dug, there may be less overall disruption and visual impact to communities. Particularly for rural areas, wireless technologies may enable less burdensome service at lower cost.

BW falls into local and wide area categories:

Wireless Local Area Networks (WLANs), such as the Wireless Fidelity (Wi-Fi) that is a high frequency network, transmit their signals within several hundred feet. WLANs are implemented as an extension to wired LANs within a building and can provide few meters of connectivity between a wired network and the mobile user. A person with a Wi-Fi enabled device such as a PC, cell phone or PDA can connect to the internet when in proximity of an access point.

Wireless Wide Area Networks (WWANs) such as WiMAX span several miles ensuring interoperability between devices, networks, and regions. WiMAX is defined as Worldwide Interoperability for Microwave Access.

Besides BW, Bluetooth is another wireless technology for low-cost, short-range wireless links and transmission of digital voice and data between mobile PCs, mobile phones, and other portable handheld devices, and connectivity to the internet. Bluetooth is widely used for hands-free cell phone operation, including wireless headsets. It can also be used to transfer data between cell phones and computer.
