PCS
Personal communication service (PCS) is a second-generation mobile communications technology also referred to as digital cellular. The digital service, which works over CDMA and TDMA interfaces, operates at the 1900 MHz frequency range.
4G mobile technology is the name for the next generation of mobile devices such as cell phones. It became available from at least one provider in the US in 2009.
The use of G, standing for generation, in mobile technology covers the major advances of the past 20-30 years. 1G technology involved the first widely available mobile phones. 2G technology, which began in the early 1990s, switched to a digital format and introduced text messaging. 3G technology improved the efficiency of how data is carried, making it possible to carry enhanced information services such as websites in their original format. The latest iPhone is the best known example of 3G and 4G technology.
4G mobile should use enhanced security measures and offer drastically faster speed. A second goal is to reduce blips in transmission when a device moves amongst areas covered by different networks. Within the United States, there are two major systems using 4G mobile technology. One is known as WiMax and is backed by Clearwire, a firm whose majority owner is Sprint Nextel. The competing system, Long Term Evolution or LTE, is backed mainly by Verizon. It was expected to be ready for testing in 2010 but not available for widespread use until 2012 LTE’s backers hoped to overcome this disadvantage by offering faster speeds and producing cheaper equipment.
Unlike previous generations of mobile technology, 4G mobile will be widely used for Internet access on computers as well as carrying cell phone communications. Customers in areas which have strong 4G coverage will be able to use it for a home broadband connection which doesn’t require any cabling to their household. It can also be used for accessing the Internet on the move without having to be in a wireless hot-spot such as those offered by some bakeries, coffee shops, airports and libraries.

Found this indie video about the Ace Hotel and wanted to share it with everyone. Harris Communications implemented a multi-carrier cellular repeater solution for the hotel prior to the grand opening.
Great question! Most likely, the trees between you and the tower have leafed out. We have had a few situations in which a clients reception was impacted by the trees around their office building.
A commercial cellular repeater or cellular booster is a type of bi-directional amplifier (BDA) as commonly named in the wireless telecommunications industry. The device is used for boosting the cell phone reception to a designated through the usage of an antenna for reception, an amplified signal and an internal rebroadcast antenna.
Bandwidth has several related meanings, for our purposes in the wireless industry there are two primary definitions:
Bandwidth (computer)digital bandwidth: a rate of data transfer, throughput or bit rate, measured in bits per second (bps).
Bandwidth (signal processing) or analog bandwidth, frequency bandwidth or radio bandwidth: a measure of the width of a range of frequencies, measured in hertz.
Bandwidth is a measure of available or consumed data communication resources. As technology grows and our desire for seamless connectivity grows, bandwidth use increases as well.
Our engineers custom design wireless solutions for our clients to suit specific needs.
This application is a cost-effective means of connecting multiple remote locations back to a central location to alleviate the need for expensive T1 or Fiber installations.
Each frequency range has a band designator and each range of frequencies behaves differently and performs different functions. The frequency spectrum is shared by civil, government, and military users of all nations according to International Telecommunications Union (ITU) radio regulations.
For communications purposes, the usable frequency spectrum now extends from about 3Hz to about 300GHz. There are also some experiments at about 100THz where research on laser communications is taking place but we won’t discuss this now. This range from 3Hz to 300GHz has been split into regions.
This is a data link protocol commonly used to establish a direct connection between two networking nodes. It can provide connection authentication, transmission encryption privacy and compression. Point to Point Connectivity is wireless can allows for the elimination of leased T-1 lines or redundancy of existing T-1 lines. This solution is available encrypted for sensitive data as well as unencrypted and has a variety of effective applications.
