The Wireless Technology Behind US Cellular's Success

US Cellular is considered as one of the top Wireless phone service providers in the United States. It is a Chicago-based U.S. company that provides quality wireless service in 189 markets in 26 states and caters to more than 6 million customers. When it comes to offering a high level of customer satisfaction, this company is rated among the leaders. That can be expected in a company that emphasizes customer support, quality network coverage and comprehensive range of wireless products and services.

To improve its network and provide excellent wireless service, US Cellular has spent millions of dollars in technological enhancements. It is currently using CDMA-1X digital technology to add more voice capacity, high-speed data products and features, and expanded coverage areas to its ever growing network.

Let us examine the technology behind the success of US Cellular more extensively. CDMA or Code-Division Multiple Access is a term that describes any of several protocols used in so-called second-generation (2G) and third-generation (3G) wireless communications. IT is a form of multiplexing wireless technology. Numerous signals will be able to occupy a single transmission channel with the help of this invention thus allowing for optimal use of available bandwidth.

This wireless wonder also uses analog-to-digital conversion (ADC) in combination with spread spectrum technology. This combination digitizes audio input into binary elements. Then, the frequency of the transmitted signal is made to vary according to a defined pattern. This process ensures that the signal can only be intercepted only by a receiver whose frequency response is programmed with the same code. This means that the signal must follow exactly along with the transmitter frequency for a successful transmission. The result is enhanced privacy and less chance of cloning because there is an overwhelming number of of possible frequency-sequencing codes. US Cellular is using the latest CDMA technology which is called 1XRTT.

To break it down, let me give you the advantages that US Cellular's CDMA 1XRTT wireless technology can offer. The foremost benefit with the use of CDMA is the minimal number of blocked calls. The risk of disruption or blocked calls is minimized because of this technologies method of passing calls between cells.

CDMA technology also reduces background noise and interference during phone calls because it combines multiple signals and improves signal strength. Since this innovation has digitally encoded, broad spectrum transmissions that help reduce wireless eavesdropping, a wireless network that uses it will have improved security and privacy.

A network that uses a Code-Division Multiple Access will also benefit from greater capacity because a large number of customers to will be able to share the same radio frequencies. CDMA can provide up to 10 to 20 times the capacity of analog equipment and more than three times the capacity of other digital platforms because it uses a broad spectrum technology.

CDMA technology will also provide expanded coverage at a reduced cost to any wireless network. This is largely due to the broad spectrum signal that provides enhanced coverage. The wireless network can be establish built with fewer cell sites with the help of CDMA than is possible with other wireless technologies.

This technology is largely responsible for US Cellular's ability to provide excellent service and satisfaction to its millions of customers across the nation. As this company continues to pump more money into improving its wireless network, it will continue to do a stellar job of providing a high level of customer satisfaction and quality wireless service.

Save Money Through a Wireless Network

Do you know how to save money by using a wireless network? If you don't then let me tell you that you can route calls through the PBX phone system to a wireless network instead of expensive phone lines thereby reducing the cost of cell phone-to-office phone calls.

Businesses can now reduce reduce their telephone expenses by using Multi-Tech CallFinder CDMA wireless networks instead of normal PSTN (public switched telephone network) lines to connect cell phone callers to company offices. The cellular gateway makes all of these happen. Remote offices can also use this technology as a complete replacement for PSTN lines. Doing so will allow the office to use a desk telephone connected directly to the gateway.

This process is also possible for larger offices that use a PBX phone system. In this case, the cellular gateway connects to a PBX trunk line or PBX extension and routes incoming and outgoing calls through a CDMA wireless network. Then, the gateway connects a company’s PBX and CDMA networks. This allows calls between the two at no charge. Additionally, in the case of landline failure for normal calls and 911 calls it provides a reliable back up. Estimates project that by using cellular service through a CallFinder instead of PSTN lines, a business could save up to twenty percent on its telephone bills.

There is also very little configuration required to install the gateway except for a few AT-style commands issued through a serial port. A person who has PBX programming knowledge can set up the routing tables in the PBX. In fact, any companies on the IT department are now in charge of PBX. The CallFinder CDMA presently supports major wireless networks like Sprint and Alltel.
