802.11 Dethrones King Ethernet
By Richard Noonan, Wireless LAN Systems Engineer
Cellular Specialties, Inc.

The real goal of fixed mobile convergence: Optimize transmission of all data, voice and video communications to and among end users, no matter where they are located or what device they are using.  To help fulfill the promise fixed mobile communications, 802.11n is quickly emerging as the Holy Grail technology — possibly as a replacement to Ethernet. That’s the word from the Burton Group, which predicts that improvements in 802.11n and its successor products will begin to erode the switched Ethernet market.

According to analyst Paul DeBeasi of Burton Group, "The 802.11n draft standard, although unfinished, is the beginning of the end for wired Ethernet as the dominant LAN access technology in the enterprise. Gigabit Ethernet provides better throughput, latency and jitter performance than 802.11n. But who cares? For many enterprises, 802.11n performance is good enough."

However, before you retire the Category 5 plumbing in the walls and ceilings in favor of ubiquitous wireless coverage facilitating “follow me” numbers to all your employees, there are several things to think about:

1. Implementing fixed mobile convergence often means interdepartmental project planning.  Let’s face it, today most IT projects take on a political-type atmosphere in the planning stages.  In large IT departments this can mean getting the network engineering and application support teams together to caucus.   In smaller organizations it may require pulling together multiple 3rd party vendors. 
2. Make sure the help desk is ready to support or provide the necessary support for your fixed mobile communications.  Don’t leave them out of the process until the end.  Planning, training and additional budgeting may be needed.
3. Standardize on a platform, but look for support of open standards and common technologies.  Keeping everyone on the same handset will greatly improve IT’s ability to support the technology, but make sure you’re positioned for future technologies by selecting products already using open standards like SIP or devices that can be upgraded easily e.g.  Windows Mobile. (e.g. Motorola TEAM)

In conclusion, the 802.11 infrastructure is no longer a single application platform and can be leveraged for a great deal more.  However, IT must also realize that solutions for VoWLAN and fixed mobile convergence may increase sales and customer service responsiveness, but may not necessarily reduce infrastructure or service expenses. Even if today you are only looking at WLAN for data, VoWLAN, in-building cellular, or campus paging, look to a future where all of these applications will be running over a consolidated radio infrastructure, but do your homework and plan accordingly.

Richard Noonan, Wireless LAN Systems Engineer at  Cellular Specialties, Inc., spent the past 13 years designing and implementing data networks for enterprise, industry, and research. Riding the trend toward ubiquitous, persistent connectivity he now focuses on wireless systems and the transformational effect they are having on modern communications.  He falls asleep every night dreaming of a fixed mobile convergence solution in every building

Choosing the Right Antenna for Your Wireless Application
By Gerardo Gonzalez, Pinyon Technologies, Inc.

When choosing an antenna for any wireless application, there are a number of factors to take into consideration and many options available.  One of the most popular choices today is the high gain antenna with strong horizontal and vertical polarization signal components. The commonly used antenna solutions like dipoles or F and inverted F antennas have a deficiency in multipath rich environments. Dipoles, F or inverted F antennas are, in most cases, vertically polarized radiating most of their energy in the vertical polarization while radiating a negligible amount of energy in the opposite polarization.

The dipole is the most commonly used antenna solution in wireless routers and gateways. The dipole is a weak option in high multipath indoor environments or in an outdoor urban or suburban environment with densely packed buildings. The dipole has a well known, donut shaped radiation pattern. It is vertically polarized, radiating most of the energy in the vertical polarization while radiating a negligible amount of energy in the horizontal polarization. The dipole, commonly used for WLAN AP’s, has a typical gain of about 2.1dBi.

In multipath environments, the dipole has an omni pattern. This pattern is of little help with multipath signals. Multipath signals commonly combine and form destructive or constructive interference. Compounding the problem is the horizontally polarized multipath signals are ignored by the dipole. In the case where the interference is constructive, it is beneficial only if it’s vertically polarized. What about the constructive interference multipath that is horizontally polarized?  Horizontally polarized multipath is surely ignored by the dipole.
  
An alternate approach is to find an antenna with an increased directivity and a good balance between the gain in the horizontal and vertical polarizations. These are positional polarizations as defined by the position of the antenna. If the dipole is rotated 90°, such that the antenna’s longest side lays parallel to the plane of a table, the radiating polarization is now horizontal, yet there is still no energy in the opposite polarization. Pinyon’s antenna technology is an example of an antenna providing good directivity and a balanced gain between horizontally and vertically polarized signals. The PCB antenna is based on a shorted resonant slot antenna technology. This antenna’s gain is specified at 3.2±1 dBi. The Pinyon antenna can be rotated 90° in the X-Y plane and still radiate on both polarizations.

The measured directivity for this antenna is 6.4 dBi. An antenna with both polarizations, like the Pinyon antenna, radiates equal amounts of energy in both horizontal and vertical polarizations and therefore has superior performance in strong multipath environments. Polarization diversity (both polarizations present) prevents signal fade by preventing polarization mismatches. This is a very desirable characteristic for an antenna since multipath is a result of signal reflections from the surrounding environment - walls, floors and ceilings.
 
This type of antenna design has another beneficial characteristic. It has gain in both horizontal as well as vertical polarizations.  The diagram of the antenna pattern first in the vertical polarization and then in the horizontal polarization shows a remarkably well balanced pattern with roughly equal gain in both polarizations.

The benefit of this balance speaks to the need to capture both horizontally as well as vertically polarized signals, especially in a multipath environment. As a result, this antenna is equally adept at receiving vertical or horizontal polarized signals. In a dipole, F or inverted F antenna the difference between the vertical and horizontal polarizations can be as much as 10 db. This makes it very difficult for a dipole, F or inverted F antenna to receive the strongest signal in a multipath environment, resulting in poor performance and eventually loss of connectivity.

To better understand the radiation pattern of this antenna, let’s look at a modeled pattern of it. Fig 2 shows a three-dimensional rendering of the antenna model. The antenna has two lobes emanating from each face of the PCB. The 3 dB azimuth beam-width is measured at 170° and the 3 dB elevation beam-width is 160° beam-width.  The beam width for this antenna is remarkably balanced.

Equipping a MIMO wireless router with antennas such as the Pinyon antenna is a way to give that router an increased chance of capturing the signals reflected from multiple directions and polarizations. 802.11n was specially geared toward achieving spatial diversity. Using dipoles, with their weakness receiving horizontally polarized signals, puts the AP at a systematic disadvantage. Horizontally polarized signals are practically ignored.  By using an antenna such as the Pinyon antenna, polarization diversity is realized when viewed from the point of view of the signal reflections due to the environment. This approach will increase the AP’s link stability and increase data throughput with better link stability.

The added flexibility of polarization diversity is helpful in multi-floor premises. AP’s will be more adept at transmitting a signal to multiple floors of a premise. With wireless devices increasingly used for the delivery of video such as IPTV, this approach introduces another way of providing additional link stability to a wireless system.

The introduction of MIMO technology-based wireless devices speaks to the industry acceptance of importance in systematically dealing with multipath. The antenna diversity that MIMO provides is the needed spatial diversity to effectively deal with multipath. Using dipoles , which cannot transmit or receive horizontally polarized signals, in a MIMO system, is a built-in weakness that can be effectively addressed. By using an antenna with good directivity that can deal with both vertically and horizontally polarized constructive signals with equal ease is the solution.
