Remotely Connecting by Satellite To the Hospital - 2005
Hospital's and the Medical Professionals associated with them across America have discovered during the last few years that a great deal of efficiency can be accomplished by utilizing the World Wide Web to connect Doctors, Surgeons, Medical Transcribers and remote or mobile Clinics together. A specialist can instantly review an X-Ray or medical chart half way around the world or from a very remote area. Although most of this connectivity is accomplished utilizing high speed terrestrial internet connections like a T1, Cable or DSL connections, there are many areas in the U.S. where this type of internet connection isn't available. Satellite internet connectivity has advanced enough during the last year or so to allow a specialist to view highly detailed graphical information (x-rays or scans from MRI equipment) in a HIPPA compliant internet environment that can be deemed "high speed". The equipment needed to accomplish this is more expensive than a DSL or Cable connection and there are somewhat more complicated security measures needed; however, more and more medical group's are seeing the benefits from this type of connection and adding satellite internet "ground stations" at the remote homes of resident doctors, medical professionals like transcribers and smaller clinics they serve. The early efforts to provide satellite internet to this field were frankly miserable failures??either not HIPPA compliant or speeds so slow you could have gotten a courier to bring it faster! DirecWay and Starband solutions just don't have enough upload speed to handle this type of activity. When you add nearly 2 seconds of latency inherent in this type of satellite connection, you have a bunch of frustrated folks! The equipment which will be the standard for several years to come includes an outdoor dish (1.2 meter is now standard), coax cabling no greater than 200' to an indoor unit which handles routing, modem functions and provides the required security. The upload transmitters are much more powerful now??up to 4 watts (compared to 1 watt or less in earlier solutions). They are capable of instantly "ramping up" the wattage during inclement weather to all but eliminate rain fade and can provide sustained speeds in the T1 or better range if required. What does all of this magic cost? The costs have dropped precipitously during the last year as a result of two main factors: underutilized transponders on many Ku band satellites covering North America and good ole competition between the hardware manufacturers. In 2002 a .74 meter dish setup with a ˝ watt transmitter ran over $2,800 for equipment and upwards of $150 per month?..and did a miserable job! In 2005, the same basic cost will bring a 1.2 meter dish and speeds of nearly 1200 kbps download and a sustained 128 kbps or better upload??including a Quality of Service (QOS) guarantee of speed from the internet service provider! Higher speeds are available for additional cost (as high as 2040+kbps downloads and 1028+kbps uploads). These speeds combined with much lower latency (these internet providers use IP technology throughout the trip through space ? not Digital Video Broadcast translated into IP) provide a reliable, secure and fast experience. For the professional or clinic unable to obtain terrestrial high speed internet, it is a great solution. About the Author:

Time to Redefine Telecom Telecommunication, according to Wikipedia, is the extension of communication over a distance. In practice, it also recognizes that something may be lost in the process; hence the term 'telecommunication' covers all forms of distance and/or conversion of the original communications, including radio, telegraphy, television, telephony, data communication and computer networking. Searching for the Right ISP When searching for the right ISP there are a number of items to look at. How much is it going to cost me? What is the connection like? What are the Features?

Defining broadband can get complicated Wireless Network Hammerin The wireless network in my house went haywire. It worked on three PCs, one had a horrible connection, and one can't connect. Between Hubby and me, we spent a lot of time researching and trying to figure out the problem. We narrowed down the possibilities few by doing tests. Hubby is the network king in our house and I learned a bit in working with him. In fact, I solved the problem... temporarily. Why You Should Switch To A Fast Internet Connection With high-speed Internet access becoming available in more and more areas, perhaps it is now available in your neck of the woods. If it is, you might be wondering if it makes sense to upgrade from dialup. For most people, the answer is probably yes! Here are a few reasons why: How Peer to Peer (P2P) Works Peer to Peer (P2P) Technology- How it works: Business Satellite Internet Products Compared - 2005 There are a number of options available for Business Class Satellite Internet connectivity in the U.S. today. New offerings seem to launch every week in 2005 and it is becoming a bit confusing for the business owner who can't obtain traditional high speed internet or can't afford the expense of running a T1 line to a location off the beaten path. I've outlined below several options for business with the positive aspects as well as negative where applicable. Each company and heavy individual user has different needs, so no one platform is a "one size fits all".

Whois Protocol - TCP/IP Suite The Whois protocol is an information service not unlike the finger service. The Whois protocol provides the client or user with information about the owner of a domain or specific IP address.

How to Choose Best ISP for Your Needs Well, the Internet access industry is starting to shake its way out. The much-anticipated consolidation of access providers is nearing its end. In broadband, this means that most users have little or no choice of providers. Though many of the changes have been hard on user choice, this is not necessarily a bad thing. In some cases, it's better to have one stable and pricey provider than 100 unstable, cheap providers. The shakeout was painful for scores of users who often were left with no connection when they needed it most. And some providers left standing don't exactly have good track records, either. 3 Tips to Fix Unreliable Wireless Connections Generally speaking, wireless computer connections are reliable.
