DSL is usually the cheapest broadband option, albeit the slowest.
DSL – DSL (Digital Subscriber Line) is a form of broadband Internet that is transmitted over standard twisted pair copper telephone lines. DSL speeds range from 256 Kbps to 6 Mbps depending on distance from the telephone company and plan that you purchase. Http://en.wikipedia.org/wiki/Digital_Subscriber_Line
Standard DSL is rapidly being replaced by newer, faster technologies. DOCSIS 3.0 cable Internet has speeds up to a blazing 305 Mbps in certain areas. Fiber optic ADSL2+ and VDSL products are offered in excess of 100 Mbps.
Google and Time Warner even have 1 Gbps fiber being installed, that’s a whopping 1000 Mbps. Http://isp1.us/blog/time-warner-brings-1-gbps-fiber-links-to-new-york/
As far as wireless service go, There are some fast 4 G wireless services available. However you’ll not want wireless for your application for two reasons.
1.) Fair Usage Limits.
Most Internet providers impose limits on the amount of data you can download before they charge you overage fees or throttle your Internet speed to a crawl.
“Unlimited Internet” is a term often used to market Internet services.
Very seldom does it actually mean unlimited. What the providers do is add what is known as a “Fair Usage Policy” you’ll find it in the small print of the contracts. The effect is that you are either throttled to a crawl or charged extra for monthly bandwidth that exceeds the providers predetermined limit.
The worst are the cellular mobile broadband providers with under 5 GB per month, Satellite Internet is a close second with some providers throttling after 200 MB per day. Most cable and DSL providers allow 100-250 GB per month.
That being said, currently cable providers have the most liberal limits. However if you consistently download in excess of 250 GB per month you risk being canceled. Read this post for more info. Http://isp1.us/blog/comcast-usage-caps-ruining-families/
At&t DSL caps at 150 GB per month and I believe Comcast is 250 GB
2.) Latency (Ping Time)
Online gaming lag is usually caused by two things, latency and upload speed.
You can check these on a speed testing site. Http://speedtest.net
Latency is the delay (ping time) in milliseconds that it takes the signal to travel to the server and back. The lower the number the better, but you’ll definitely want a ping time of under 150 ms or you’ll have major problems.
Upload speed also plays a factor in updating your player position data to the gaming server. Slow upload speeds can cause your online game to lag. The faster the better, but at least 0.5 Mbps would be my minimum recommendation.
Another factor that comes into play is if you are using a wired (Ethernet) or wireless connection to your PC or gaming console.
Unfortunately any network without cables will have latency issues. This includes wireless mobile broadband and satellite systems, but also can be caused by wireless router connections.
By nature, interference in wireless systems causes problems with smooth, consistent speeds.
A lot will depend on what Internet providers are available in your specific area and what levels of service they offer in that location.
To compare your local competitors, go to a ISP comparison site that lets you input your address, http://isp1.us/find/ and compare the pricing and terms of the offers that are available in your area.
The physical address is needed because some services, particularly DSL, are very distance sensitive. For example you might be able to get a specific level of service while your next door neighbor can’t.
You’ll want to pick the fastest plan that fits your budget. In some areas this can be 300 Mbps+. But these high end broadband plans are expensive. You may find that something in the 5 to 50 Mbps range might satisfy your needs at a much lower cost.
