Making the move to 802.11n? Though the rewards are significant, they come with a cost. The increased complexity of 802.11n can be a bit maddening, and it will definitely impact the way you design, monitor, and maintain your WLAN. MIMO? Channel bonding? Aggregation? If these terms aren’t currently part of your WLAN vocabulary, they certainly will be by the time you make the move. And even though the specification has been ratified for some time now, 802.11n hardware continues to evolve.
Join us as we explore the number of MIMO streams, channel bonding, guard interval lengths, and other characteristics that define your WLAN capabilities. We’ll also characterize the current state of commercially available 802.11n hardware, arming you with the information you need to determine if, when, and how you want to make the move.
In these slides, we will cover:
- Key technologies that are new to 802.11n
- The relative importance of each technology in contributing to increased performance
- The current “state of the art” of commercially available 11n equipment
What you will learn:
- What new 11n technologies are most important to you
- When to use the various 11n technologies

The document summarizes the development of the IEEE 802.11n standard for wireless LAN technology. It describes how the standard was developed through a working group process that included initial discussions, the formation of study groups to determine scope, and a task group that evaluated proposals and drafted the standard. Key technologies included in the 802.11n standard are MIMO and 40MHz bandwidth to increase data rates to over 100Mbps and the use of frame aggregation to enhance MAC throughput. Lessons learned from the development process included the need to limit new features and narrow the scope of amendments to speed up time to market.
The document discusses the history and status of the IEEE 802.11n standard for wireless local area networks. It began development in 2004 with the goal of increasing data throughput up to 540 Mbps. Two competing proposals were eventually merged. Key technologies included in the standard are MIMO and OFDM to improve throughput and range. The standard was finalized in 2006 and incorporated new technologies to support throughput up to 600 Mbps.
Main Differences between LTE & LTE-AdvancedSabir Hussain
LTE stands for Long Term Evolution.
In Nov. 2004, 3GPP began a project to define the long-term evolution (LTE) of Universal Mobile Telecommunications System (UMTS) cellular technology.
LTE systems have:
Higher performance
Backwards compatible
Wide application
Data Rate:
Instantaneous downlink peak data rate of 100Mbit/s in a 20MHz downlink spectrum (i.e. 5 bit/s/Hz)
Instantaneous uplink peak data rate of 50Mbit/s in a 20MHz uplink spectrum (i.e. 2.5 bit/s/Hz)
Cell range:
5 km - optimal size
30km sizes with reasonable performance
up to 100 km cell sizes supported with acceptable performance
Cell capacity:
up to 200 active users per cell(5 MHz) (i.e., 200 active data clients)
Mobility
Optimized for low mobility(0-15km/h) but supports high speed
Latency (delay)
user plane < 5ms
control plane < 50 ms
Improved broadcasting
IP-optimized
Scalable bandwidth of 20MHz, 15MHz, 10MHz, 5MHz and <5MHz
Co-existence with legacy standards (users can transparently start a call or transfer of data in an area using an LTE standard, and, when there is no coverage, continue the operation without any action on their part using GSM/GPRS or W-CDMA-based UMTS)
LTE Advanced is a mobile communication 4G standard approved by International Telecommunications Union (ITU) in Jan 2012.
LTE-Advanced (LTE-A) is an emerging and, as the name suggests, a more advanced set of standards and technologies that will be able to deliver bigger and speedier wireless-data payloads.
The most important thing to know is that LTE-A promises to deliver true 4G speeds, unlike current LTE networks. You can expect the real-world speed of LTE-A to be two to three times faster than today’s LTE.
To be considered true 4G (also known as “IMT-Advanced”), a mobile network must fulfill a number of benchmarks, including offering a peak data rate of at least 100 megabits per second (Mb/s) when a user moves through the network at high speeds, such as in a car or train, and 1 gigabit per second (Gb/s) when the user is in a fixed position.
The highest possible rates are never achieved in real world conditions. Actual rates will be variable, but we can expect LTE-A to be at least five times as fast as most LTE networks today, and that’s great news for video streaming.
LTE Advanced is supposed to provide higher capacity, an enhanced user experience, and greater fairness in terms of resource allocation.
It does this by combining a bunch of technologies, many of which have been around for some years, so we’re not really talking about the implementation of an entirely new system here.
Following the phenomenal global success of LTE, the stage is set for the foray of LTE Advanced. Industry leaders have already gotten a head start with its first step: carrier aggregation. Join us to explore the success factors behind LTE proliferation and an impressive lineup of enhancements that LTE Advanced is bringing.
