Your question: Why are there 12 subcarriers in LTE?

In the downlink, the subcarriers are split into resource blocks. This enables the system to be able to compartmentalise the data across standard numbers of subcarriers. Resource blocks comprise 12 subcarriers, regardless of the overall LTE signal bandwidth. They also cover one slot in the time frame.

How is LTE transmitted?

The LTE network is based on Internet Protocol (IP) standards, the kind that delivers Web pages to your computer, and adds voice data to the transmission streams [source: 4G Americas]. It uses a schematic called OFDMA, or Orthogonal Frequency Division Multiple Access, which is similar to the OFDM approach in WiMAX.

What is the difference between RB and PRB in LTE?

RB i.e. Resource block is a generic term looks like that you want to know the VRB virtual resource block and PRB physical resource block. In OFDMA, users are allocated a specific number of subcarriers for a predetermined amount of time. These are called PRB i.e. physical resource blocks.

Is LTE good or bad?

LTE is a very good, easily deployable network technology, offering high speeds and low latencies over long distances. … AT&T’s LTE service was much better than Sprint’s, but still bad with an average download speed of 7.6Mbps and an average upload speed of 2.4Mbps.

Is LTE better than Fibre?

LTE is not as fast as Fibre, but it moves house more easily. LTE at Home can achieve speeds of up to 50Mbps. It’s not quite as fast as Fibre, and because it’s airborne, a little more prone to external factors such as bad weather playing a part in the speeds you get.

Is LTE better than 4G?

In laymans terms, the difference between 4G and LTE is that 4G is faster than LTE. … Older LTE mobile devices launched right prior to 4G deployment cannot provide 4G speeds because they aren’t built to handle it. In 2020, all cellular carriers should now offer 4G service, if not offering 5G already.
