Internet access Technologies in Sri Lanka

Broadband Technologies

ADSL - Uses typical twisted pair cable that come home. Maximum downstream up to 8 Mbps. Divide the voice and data signals on the telephone line into three frequency bands.

Internet Leased Line - Internet leased lines are usually available at speeds of 64k, 128k, 256k, and 512k, T1 or E1).

Optical Fiber - Technology which bring fiber step closer to the subscriber. In Sri Lanka vastly use in large organizations. Can go up to speed of up to 1 Gbps

HSPA - Supports data rates up to 27 Mbit/s in the downlink and 5.8 Mbit/s in the uplink. In Sri Lanka do not provide unlimited packagers.

Wi-Max - Can go for over a much greater range.  Point-to-multi point: last-mile internet access.  People can go up to 52 Mbps. Good solution for the people who can’t get ADSL connection due to long distance.

LMDS - LMDS offers a microwave solution with a reduced cost per link. It transmits in a point to multi-point fashion over a wide coverage area.  LMDS channel is capable of 45 Mbps downstream.

CDMA - Can achieve maximum capacity of 2Mbps. Popular as wireless internet access technology in Sri Lanka.

Wi-Fi - Based on the IEEE 802.11x standard and transmitting in unlicensed spectrum at 2.4 GHz. support data rates up to 54 Mbps.

Narrow Technologies

Dial-up - Uses the facilities of the public switched telephone network (PSTN). Use same frequency voice band of 0- 4 kHz. Few years ago very popular, but only can have 56 kbps.

ISDN - Much faster speed of 256 kbits/s. But not considered as broadband. Not popular because had to use separate equipments.

WAP - Most use of WAP involves accessing the mobile web from a mobile phone. People can’t go much capacity through this wireless mobile technology.

GPRS - Can achieve maximum speeds of up to 9.6 kbps. This is mobile wireless technology.  Mainly used   for web browsing.

Benefits of Bluetooth

Wireless - As you probably already know, there are many benefits and advantages to using wireless devices. Along with improving safety as a result of eliminating wires you don't need, wireless also offers you plenty of other advantages.

Standardized protocol - Bluetooth is standardized wireless, meaning that a high level of compatibility among devices is guaranteed. Bluetooth will connect devices to each other, even if they aren't the same model.

Low interference - Bluetooth devices almost always avoid interference from other wireless devices. Bluetooth uses a technique known as frequency hopping, and also low power wireless signals.

Low energy consumption - As a result of Bluetooth using low power signals, the technology requires very little energy and will use less battery or electrical power as a result. This is an excellent benefit for mobile devices, as Bluetooth won't drain the battery.

Sharing voice and data - The standard for Bluetooth will allow compatible devices to share data and voice communications. This is great for mobile phones and headsets, as Bluetooth simplifies driving and talking on your cell phone.

Instant PAN (Personal Area Network) - You can connect up to seven Bluetooth devices to each other within a range of up to 30 feet, forming a piconet or PAN. For a single room, you can also set up multiple piconets.

Upgradeable - Upgradeable is the standard for Bluetooth. There are newer versions of Bluetooth in the works, which offer many new advantages and backward compatible with older versions.

The technology stays - Bluetooth technology is a worldwide, universal wireless standard. With it being as popular as it is, you can count on it being around for years to come. As more and more devices start to use Bluetooth technology, more manufacturers will be eager to make their products compatible. A chain reaction will occur, making Bluetooth the standard for cutting edge wireless.

Webcam software senses motion, sounds alarm, captures snapshots, records video, and sends captured images by e-mail

Modern professional surveillance software works with any webcamera, Internet cameras, and major capture cards.

Security software has become so complicated that the typical user who has been busy minding his store instead of pouring over electronics and ip know-how articles can be easily overwhelmed when it comes time to setup or renew his surveillance system.
Luckily, there is modern professional security software that simplifies much of the decision making. You don't necessarily have to get rid of a working analog CCTV system in order to renew to a streaming video that can be watched from any ip connected computer or 3G phone. Video capture cards can digitally convert the pictures for broadcast. Until recently, there had been no real attempts to standardize the new IP cameras; every make and manufacturer functioned a tiny differently. And when you connect web cameras into the merge, using one software to rule them all was unwieldy.
Professional surveillance application is now available that will work for any webcam or Internet camera and for most capture cards as well. You can monitor whatever your movement sensors are picking up at your home or company while you can be half a world away. The software itself may not be easy, but it can make life simpler for you.

Webcams are usefull for more than just making ip communications more sensible. They can furthermore be an awfully effective device for use in residence or firm protection. Application is now available that can sense movement and use it as a trigger for different procedures.
The way that it works is to study the image sent by a webcam that is either connected by USB or using a video capture device for movement. Once it picks up that movement, it can then acquire any number of actions, including triggering an siren.
A more popular software, though, is to either send live shots of what is happening in the scene that is covered by the camera or to even webcast using live streaming accurately what is happening with both audio and picture. If installed secretly, this software could even be used for covert surveillance.

I can use this webcast for surveillance purposes, allowing me to watch what's going on in my room at any moment from a remote viewing station.
As long as I have the web camera running and a remote station with Internet access, I can view the apartment. With the software and the webcam, I can change the settings to capture picture, identify activity (if I don't want to keep the webcam running at all times), or use a combination of a live feed and recorded video to realize a protection system that takes full benefit of new know-how.
