The Motorola i1 is one such handset–it’s the first Google Android phone for Boost Mobile, and it’s also the first Google Android smartphone to run on Nextel’s iDEN network. It’s quite a rugged device–for a touch screen phone anyway–and it’s also the only Android phone to support push-to-talk, which is a big deal if you’re a Boost or Nextel customer. However, the i1 is saddled with Android 1.5, which is a relatively obsolete version of the operating system, and the iDEN network doesn’t have fast data speeds. However, Motorola may release a software update in the future, so we’ll keep hoping for improvements on that front. Overall, it’s certainly not the best Android phone we’ve seen, but it makes for a serviceable touch-screen smartphone, especially if you’re an iDEN die-hard. The Motorola i1 is available for 9.99, but bear in mind that price without a contract from Boost Mobile.
Dish Network, and other satellite TV providers didn’t just appear over night. The development of satellite television took years and its origins can be traced back to the 1950s and the space race.
The original concept of satellite television is often attributed to writer Arthur C. Clarke, who was the first to suggest a worldwide satellite communications system. Funding for satellite technology in the U.S. began in the 1950s, amidst the space race, and the Russian launching of the satellite Sputnik in 1957.
The first communication satellite was developed by a group of businesses and government entities in 1963. Syncom II orbited at 22,300 miles over the Atlantic; the first satellite communication was on July 26, 1963, between a U.S. Navy ship in Lagos, Nigeria and the U.S. Army naval station in Lakehurst, New Jersey.
Overloaded land based distribution methods had the telephone companies utilizing satellite communication way before the television industry even came into the picture. In fact, it was not until 1978 that satellite communication was officially used by the television industry.
In 1975, RWT’s co-founder and BBC transmitter engineer Stephen Birkill built an experimental system for receiving Satellite Instructional Television Experiment TV (SITE) transmissions, beamed to Indian villages, from a NASA geostationary satellite.
Birkill extended his system, receiving TV pictures from Intelsat, Raduga, Molniya and others. In 1978, Birkill met up with Bob Cooper, a cable TV technical journalist and amateur radio enthusiast in the U.S., who invited him to a cable TV operators’ conference and trade show, the CCOS-78. It was there that Birkill met with other satellite TV enthusiasts, who were interested, and ready to help develop, Birkill’s experiments.
Interest in Television Receive Only (TVRO) satellite technology burst forward. The American TVRO boom caught the attention of premium cable programmers, who began to realize the potential of satellite TV. Back in the mid-1970s, TV reception was the under the control of international operators, Intelsat and Intersputnik.
On March 1, 1978, the Public Broadcasting Service (PBS) introduced Public Television Satellite Service. Satellite communication technology caught on, and was used as a distribution method with the broadcasters from 1978 through 1984, with early signals broadcast from HBO, TBS, and CBN (Christian Broadcasting Network, later The Family Channel). TVRO system prices dropped, and the trade organization, Society for Private Commercial Earth Stations (SPACE), and the first dealerships were established.
Broadcasters realized that everyone had the potential to receive satellite signals for free, and they were not happy. But the Federal Communications Commission (FCC) was governed by its open skies’ policy, believing that users had as much right to receive satellite signals as broadcasters had the right to transmit them.
In 1980, the FCC established the Direct Broadcast Satellite (DBS), a new service that consisted of a broadcast satellite in geostationary orbit, facilities for transmitting signals to the satellite, and the equipment needed for people to access the signals. In turn, broadcasters developed methods of scrambling their signals, forcing consumers to purchase a decoder, or a direct to home (DTH) satellite receiver, from a satellite program provider.
From 1981 to 1985, the big dish satellite market soared. Rural areas gained the capacity to receive television programming that was not capable of being received by standard methods.
The Satellite Broadcasting and Communications Association of America (SBCA) was founded in 1986 as a merger between SPACE and the Direct Broadcast Satellite Association. But by this point, American communication companies had soured on the prospect of satellite TV. Broadcast cable was very successful at this time, and the satellite industry received a lot of negative press coverage. Fifty percent of all satellite retailers closed their businesses.
Business eventually recovered, but the illegal theft of pay television signals was still a problem. Ultimately, encryption has proven to be the ultimate salvation of the satellite industry as it has made the transition from a hardware to software entertainment-driven business.
Early successful attempts to launch satellites for the mass consumer market were led by Japan and Hong Kong in 1986 and 1990, respectively. In 1994, the first successful attempts in America were led by a group of major cable companies, known collectively as Primestar.
Later that year, Direct TV was established, and in 1996, the DISH Network, a subsidiary of Echostar, also entered the satellite TV industry. DISH Network’s low prices forced competing DBS providers to also lower their prices. And an explosion in the popularity of digital satellite TV ensued.
Two way radios are good news for your business. As contrary to cellphones, they provide you an even cheaper way to keep in contact with your employees and colleagues and organisation members. And more so if your job requires communication between on-field workers and in-house office workers, these devices can prove to be invaluable. Through these radios, you can always be in the loop as to what is required for the business proceedings to continue in an informed manner. So you have a cost-effective method for sustaining easy accessibility among your organisation members.

In the real world, businesses come in every size, from self-employed entrepreneurs like me to mega malls like Wal-Mart.
On the Internet, companies come in every size, too, from a stand-alone ebook sales page with webmaster and owner all in one, to 300 pound gorilla like Amazon, with over a million pages, who requires the entire population of a small country to serve as webmaster.
If your site is a single page, it is its own network. But if your site is any bigger, and you have plans to grow, it is a network or is fast becoming one. You need network monitoring.
Most ecommerce webmasters are at least somewhat familiar with website monitoring. Many use a website monitoring service or software to keep track of “uptime” and “downtime”.
At your local shopping mall, serious business requires more than just knowing when the front doors are open and when they are closed. Serious ecommerce needs to know more than just when the site is accessible. That is what network monitoring is all about.
What Network Monitoring Monitors
Chances are, your e-business owns one of the following, or uses one of the following remotely:
DNS servers: These are used to translate your site name, like www.URL.com, to the numbers called “IP addresses” that computers understand. If DNS servers are not working properly, end-users will not be able to find your site and will get an error. Usually only an external or remote monitoring service will detect such a problem.
An FTP server: File Transfer Protocol servers are used to help you
exchange files with remote users. If you use FTP, a monitoring
service can make sure it is always up and running.
POP3 and SMTP servers: These are used for exchanging emails. If you are using email, chances are you are using SMTP and POP3. If your SMTP server is down, everyone who sends you email will receive an error, stating that your mail server is down and cannot accept incoming email. To say that the impression this leaves your customers is bad would be an understatement. If your POP3 server is down, you will be unable to retrieve email from your mailbox. Once again, only external monitoring will prevent such a problem.
Firewalls: Many businesses use firewalls to protect their internal network from un-authorized traffic, such as spyware, viruses and sabotage by competitors. Furthermore, a firewall is your first line of defense. If your firewall goes down, your whole network may actually become inaccessible from outside. In other words, if you host your own web site and mail servers, those will become
inaccessible to the outside world if your firewall goes down. Once again, remote network monitoring is required to detect that a problem exists and quickly get it repaired.
Internet connections: Users come to your network from multiple backbones, depending on the company they use to connect to the Internet and their location. It is important to insure that your connection performs well for each user. A remote monitoring service can ping your networks from multiple locations around the world, thus testing most major routes to your web server or network. Before hiring a network monitoring service, check to see that they have both your customer geography and the Internet backbone layout covered.
Very few websites of any size and functionality are anything less than a complete network, and many networks rely on servers in different parts of the world.
A good network monitoring service can ensure, as a base, that all servers are properly functioning, that data can be sent to and received from each server, and that each function sharing the server responds as required. An advanced network monitoring service can even remotely monitor the temperature of your servers.
What you need to monitor depends on how extensive your network is. A network monitoring expert can help you determine what needs monitoring. If you own the servers, or are remotely hosted on dedicated servers, you most likely need everything monitored. If your site is hosted on shared servers, you might need fewer functions monitored.
