What is HSDPA ?

HSDPA, short for High-Speed Downlink Packet Access, is a new protocol for mobile telephone data transmission. It is known as a 3.5G (G stands for generation) technology. Essentially, the standard will provide download speeds on a mobile phone equivalent to an ADSL (Asymmetric Digital Subscriber Line) line in a home, removing any limitations placed on the use of your phone by a slow connection. It is an evolution and improvement on W-CDMA, or Wideband Code Division Multiple Access, a 3G protocol. HSPDA improves the data transfer rate by a factor of at least five over W-CDMA. HSDPA can achieve theoretical data transmission speeds of 8-10 (megabits per second). Though any data can be transmitted, applications with high data demands such as video and streaming music are the focus of HSDPA.

HSDPA improves on W-CD MA by using different techniques for modulation and coding. It creates a new channel within W-CDMA called HS-DSCH, or high-speed downlink shared channel. That channel performs differently than other channels and allows for faster downlink speeds. It is important to note that the channel is only used for downlink. That means that data is sent from the source to the phone. It isn't possible to send data from the phone to a source using HSDPA. The channel is shared between all users which lets the radio signals to be used most effectively for the fastest downloads.

Container ISO Codes

Sometimes we need to identify containers by looking at the ISO codes. I have listed mainly use ISO codes for Depot users/surveyors.

What happened to a Net Admin..

Few years ago I joined with a company as a Network Administrator and by the time I joined the company they describe my job’s main tasks as below;

1. Maintain the existing network infrastructure, evaluate, and recommend new technology to implement.
2. Maintenance and troubleshoot CISCO router, 2 ADSL connection and Windows 2000 server / workstation.
3. Introduce new technology to enhance productivity.

And there were some more IT related stuff. (You know all the rubbish you get in your Appointment Letter.: P) I work very coolly dooly for sometimes and had much spare time for myself.

New involvement after few months after joining;

1. Inspecting and estimating damage containers (ISO standard)
2. Lead the Operation of the container yard.
3. Train the staff
4. Set standard and procedures
5. Discuss /negotiate with our main Shipping line regarding IT / Operational issues
6. Follow up container repair (ISO standard)
7. Invoicing


This helped me to understand another industry (Container Depot / Shipping) which I didn’t have a clue. :)

HAPPY NEW YEAR..!!

CCNA

I started CCNA few months ago @ SLIIT and end of this month I'm hoping to do the final exam. Actually it is not a easy job to do, without the help from assignments, simulations (Router Sim, Boson)and some useful pass papers, especialy from pass4sure & Testking.

The content of the course is well organized by Cisco.It covers a vast area in Routing and Switching. Most of us have the theoretical background but we lack the practical aspect of it.

Wasgamuwa Trip

After a short meeting at Mahasen's place we decided to go to Wasgamuwa on Sunday morning. This became a last trip we go as a bachelors..!!
