New Wireless Data Transmission Protocols

Wireless Logo

Many devices and gadgets today are taking advantage of wireless networks to send and receive data more conveniently. But as the need for faster and larger data transfers increase over the years, current wireless data transmission standards may not be able to hold on much longer in terms of performance or may be considered a hindrance if it is not able to compare with the speeds achieved by wired protocols. But is may be slowly getting there with the development of new wireless data transmission protocols.

There are two new wireless data transmission protocols being developed and planned for introduction around 2012. the two new wireless standards, called 802.11ac and 802.11ad, will allow the introduction of wireless data transfers for up to 1 Gbps or faster. At this speed, people may be able to accommodate larger data transfers faster among multiple devices in a wireless network.

The 802.11ac protocol will be an update on the current 802.11n standard currently in use for WLAN. This new future standard will enable a leap of data transmission speed between 300 to 400 mbps, more than what is needed to carry multiple compressed video streams in a single channel. But this future standard won’t be able to carry the capacity needed for high definition streams.

In this case, the 802.11ad standard is being developed to accommodate the need for high definition video streams in the future over a wireless network. It makes use of the newly available 60GHz spectrum frequency band for data transmission, doing away with the current standard for today’s Wi-Fi networks in the 2.4 GHz and 5GHz bands. With the 60 GHz spectrum, devices may be able to use multiple channels to transmit 1 gbps worth of uncompressed video signal each.

But the disadvantage of the 802.11ad standard is that its signal waves may not be able to penetrate barriers such as walls and the energy waves may be readily absorbed. And because of this, the future for the 802.11ad standard is for use in transmitting large data packets in short distances such as between several devices found in the same room.
