In practice, access points may not have an ideal implementation and may therefore not be able to achieve even It built on the performance and played a pivotal role in further establishing Wi-Fi as a major wireless standard. A Long Range For Wi-Fi systems the data packets sent over the radio interface can be thought of as consisting of two main parts:. Orthogonal Frequency Division Multiplex, OFDM is a form of signal format that uses a large number of close spaced carriers that are each modulated with low rate data stream.

Rates vary widely based on distance, obstructions, and interference.

It is customary for data packets to be split into different elements. By midmost dual-band Views Read Edit View history. Archived PDF from the original on C1 For Chinese regulation.

This enables the transmitting station to compute the Duration field in the MAC header. Even with such separation, some interference due to side lobes exists, though it is considerably weaker. The close spaced signals would normally be expected to interfere with each other, but by making the signals orthogonal to each other there is no mutual interference.

This article needs additional citations for verification. Details of making b and g work well together occupied much of the lingering technical process. Up to 6, [13] 6. iefe802

This page was last edited on 28 Decemberat Of the 52 OFDM subcarriers, 48 are for data and 4 are pilot subcarriers with a carrier separation of 0. Journal of ICT Standardization. It works in the 2. Despite this, the separation between different Wi-Fi access points means that interference is not normally too much of an issue. The advantages of using OFDM include reduced multipath effects in reception and increased spectral efficiency.

Unsourced material may be challenged and removed. To prevent interference, there are only three non-overlapping usable channels in the U. Supplier Directory For everything from distribution to test equipment, components and more, our directory covers it. This is the format into which data is converted jahg the PLCP for transmission. In turn this ensures that the NAV value of To provide the maximum capability while maintaining backward compatibility, four different physical layers are used – three of which are defined as Extended Rate Physicals, ERPs.
