What is bandwidth, how does it relate to the speed of the network, and how much bandwidth does LCSC have?
People often confuse bandwidth with the speed that bits of data travel over the network. In reality, all data travels at the speed of light (186,000 mile/second). Bandwidth is related to how close the "bits" of data can travel together while still being able to be read at the receiving end. So, the higher the bandwidth, the closer the data can travel together over the network, so the more data can be sent in a given amount of time.
An analogy would be that all cars can drive 55 mph, however, on a gravel/dusty road these cars must stay a long way apart to prevent damaged windshields, wrecks, etc. So only 10 cars might be able to travel down the road in an hour. If you have a group (file) of 50 cars, it'll take 5 hours to move them. On a super highway, paved with multiple lanes, the cars can travel closer together and side-by-side, so more cars can travel down the road in the hour (still going 55 mph). If 100 cars can travel in an hour, the group (file) can now move in only 1/2 hour. That's why higher bandwidth means a "faster" network.
LCSC has different bandwidth at different locations. The most important bandwidth measurements for our customers are:
- Each device on the network has a dedicated 100meg (100 Million bits of data/second) within their building.
- LCSC's network backbone (between the buildings and to the data center in SGC) is 1gig (1 billion bits/second).
- LCSC's connection to the Internet is three T1 lines (Each T1 is 1.544meg for a total of approximately 4.63 million bits/second). This is one area where increased bandwidth is needed at LCSC, but it is also the area where bandwidth is "leased" from a provider resulting in a substantial reoccurring cost.
Common bandwidth terms include:
T1 - a connection of 1.544meg
DS3 - a connection equivalent to 28 T1 lines
OC3 - a connection equivalent to three DS3 lines
CAT-V - (Category 5) Building wiring capable of 100Meg bandwidth
CAT-Ve - (Category 5 enhanced) Capable of 150Meg bandwidth
What is the wireless network coverage at LCSC?
If you have a laptop and want to go wireless on the LCSC campus, there are just a few simple steps to follow, and a small investment to make. Here is what you need to do:
1) Purchase a wireless LAN adaptor. The adaptor must support 802.11b or 802.11b/g protocol which is standard.
2) Install the card and the software that comes with it. Some will require no additional setup and will do everything automatically, while others may require some assistance. The type of wireless connection to select is "Access Point" which should be the default. The wireless network ID is [lcsc-wlan], although the system should find it automatically.
After this, if you need assistance on your LCSC laptop, please contact the IT HelpDesk at ext. 2231. Wireless is available in the SUB, Library, WCC, Reid Centennial Hall, Sam Glen Complex, Administration Building, Activity Center West, Wittman Complex, Meriwether Lewis Hall, and inside the Gym at the Activity Center. Outside Coverage area includes Harris Field and the Centennial Mall area. Sit back, and enjoy web surfing "unplugged".
How does the laptop checkout program work?
Wireless laptops are now available for checkout by all current LCSC students at the SUB and Library. There is no charge for usage, however late fees will be assessed if the laptop is not returned on time.
