What is LMD?

LMDS is an abbreviation for local multipoite distribution service. It is a type of high -speed wireless internet transmission that works using a microwave. Suddenly it was considered a potential solution for expanding domestic broadband services, especially in the United States. Today it seems somewhat outdated and is generally overtaken by competing technologies.

LMDS microwaves have a much higher frequency than radio waves. While most of the current wireless internet services broadcast at approximately 2 to 3 GHz frequencies, LMD uses approximately 26 to 31 GHz frequencies. Precise frequencies differ from location to location and ranges can be limited by local regulations and licenses. This means that information can be converted from one point, local station to multiple users. The information transmitted back by any user returns only to the local station than to all users.

Due to this ability, LMDS was once promoted as MOImporting solutions for obtaining high -speed internet access to homes. This was considered a way to bypass the high cost of transferring high -speed information from local telephone exchange to households. Since LMD can theoretically transmit a large amount of data at high speeds, the "wireless cable" was sometimes dubbed as a way to get through the concept.

There is an argument that LMD failed to take off because of unfortunate timing. At the beginning of the 21st century, many technological companies, whose stock prices were probably overestimated, suddenly began to get into financial problems. This has led to a sudden lack of confidence in this industry that could have caused some companies to leave or slowed down plans to develop LMDs.

Today is probably needed LMD. Many houses in areas that seemed to have the most fuges have the possibility of a fixed line for high -speed inTernet such as broadband ADSL or cable services. There are also competitive systems that are faster, more reliable and have better industry support. Internet users also now have more options for receiving Internet services via mobile phones.

LMD in the United States still exist and is regulated by the Federal Communication Commission. As with many regulated FCC technologies, the country is divided into 493 areas known as the basic trade areas, each based on the capital. In each area, two licenses are awarded for ten -year intervals through the auction system. Both licenses cover services working on two different frequencies.
