1 What is ? The standards are a group of evolving specifications defined by the Institute of Electrical and Electronic Engineers (IEEE). Commonly referred to as Wi Fi the standards define a through theair interface between a wireless client and a base station access point or between two or more wireless clients. There are many other standards defined by the IEEE, such as the Ethernet standard. Why are standards important? Standards are a set of specifications that all manufacturers must follow in order for their products to be compatible. This is important to insure interoperability between devices in the market. Standards may provide some optional requirements that individual manufacturers may or may not implement in their products b In 1995, the Federal Communications Commission had allocated several bands of wireless spectrum for use without a license. The FCC stipulated that the use of spread spectrum technology would be required in any devices. In 1990, the IEEE began exploring a standard. In 1997 the standard was ratified and is now obsolete. Then in July 1999 the b standard was ratified. The standard provides a maximum theoretical 11 Megabits per second (Mbps) data rate in the 2.4 GHz Industrial, Scientific and Medical (ISM) band g In 2003, the IEEE ratified the g standard with a maximum theoretical data rate of 54 megabits per second (Mbps) in the 2.4 GHz ISM band. As signal strength weakens due to increased distance, attenuation (signal loss) through obstacles or high noise in the frequency band, the data rate automatically adjusts to lower rates (54/48/36/24/12/9/6 Mbps) to maintain the connection. When both b and g clients are connected to an g router, the g clients will have a lower data rate. Many routers provide the option of allowing mixed b/g clients or they may be set to either b or g clients only. To illustrate 54 Mbps, if you have DSL or cable modem service, the data rate offered typically falls from 768 Kbps (less than 1 Mbps) to 6 Mbps. Thus g offers an attractive data rate for the majority of users. The g standard is backwards compatible with the b standard. Today g is still the most commonly deployed standard. IEEE a/b/g/n Wi Fi Standards and Facts Page 1

2 802.11a Ratification of a took place in The a standard uses the 5 GHz spectrum and has a maximum theoretical 54 Mbps data rate. Like in g, as signal strength weakens due to increased distance, attenuation (signal loss) through obstacles or high noise in the frequency band, the data rate automatically adjusts to lower rates (54/48/36/24/12/9/6 Mbps) to maintain the connection. The 5 GHz spectrum has higher attenuation (more signal loss) than lower frequencies, such as 2.4 GHz used in b/g standards. Penetrating walls provides poorer performance than with 2.4 GHz. Products with a are typically found in larger corporate networks or with wireless Internet service providers in outdoor backbone networks n In January, 2004 the IEEE task group initiated work. There have been numerous draft specifications, delays and lack of agreement among committee members. Yes, even in the process of standards development, politics are involved. The Proposed amendment has now been pushed back to early It should be noted it has been delayed many times already. Thus n is only in draft status. Therefore, it is possible that changes could be made to the specifications prior to final ratification. The goal of n is to significantly increase the data throughput rate. While there are a number of technical changes, one important change is the addition of multiple input multiple output (MIMO) and spatial multiplexing. Multiple antennas are used in MIMO, which use multiple radios and thus more electrical power n will operate on both 2.4 GHz (802.11b/b) and 5 GHz (802.11a) bands. This will require significant site planning when installing n devices. The n specifications provide both 20 MHz and 40 MHz channel options versus 20 MHz channels in a and b/g standards. By bonding two adjacent 20 MHz channels, n can provide double the data rate in utilization of 40 MHz channels. However, 40 MHz in the 2.4 GHz band will result in interference and is not recommended nor likely which inhibits data throughput in the 2.4 GHz band. It is recommended to use 20 MHz channels in the 2.4 GHz spectrum like b/g utilizes. For best results of n, the 5 GHz spectrum will be the best option. Deployment of n will take some planning effort in frequency and channel selection. Some 5 GHz channels must have dynamic frequency selection (DFS) technology implemented in order to utilize those particular channels. Another consideration of n is the significantly increased electrical power demand in comparison to the current b/g or a products. This is primarily due to multiple transmitters. The Wi Fi Alliance is testing and certifying compatibility of n radio draft 2.0 specifications. There are several realities to consider. They are only testing against some basic criteria and interoperability points. Also the number of devices being tested against each other is low. This certification does not provide any protection against changes to the n standard prior to ratification. IEEE a/b/g/n Wi Fi Standards and Facts Page 2

3 VHT An IEEE working group has been working on efforts for the successor to n in the last one year. This effort is known as Very High Throughput (VHT) and focuses on changing to support 1 Gigabit per second (Gbps) wireless LAN standard. Which wireless standard, b, g or n should I buy? Today, you will find the stores full of draft n products. The estimates show that 94% of the buyers of these products are consumers or small businesses, who frankly don t know about standards issues. The majority of enterprise or corporate users are not investing into these draft products. At issue is both the possibility of these products not being compliant with any final standards and the desire not to suffer potential headaches until the technology is fully ready. Interestingly technical writers for trade journals or the press tend to promote heavily n despite the fact that AIR802 has polled its customers in the USA and in other countries with over 98% reporting that they have no interest in n until the standard is ratified and the technology and products have been proven. For reference, the majority of AIR802 customers are government agencies; value added resellers, computer networking companies (installing wireless products in both residential and small business environments), consumers and distributors. Therefore, it appears that most buyers have taken a very cautious wait and see approach despite optimistic editorial articles. For the majority of residential and small and medium size business users, the single largest concern among users is to provide the desired signal coverage followed by reliability. For these users current b/g products with high RF power output would provide the most desirable results. The common consumer equipment found in retail stores have between 30 to 65 mw of RF output power. However, within the same general price range, equipment with 250 mw of RF output power or higher can be purchased. In comparison tests, high power b/g routers provide significantly greater distance and coverage and as a result higher throughput than any typical lower powered b/g or n draft product in the market. For most users more data throughput is not a critical decision factor. If the wireless network is being used for Internet access and the DSL or cable modem service, which is typically less than 1 Mbps to 6 Mbps depending on the service provider or plan, the typical 25 Mbps data throughput on a high RF powered b/g device is more than sufficient. In fact today, thousands of networks supporting IP video surveillance are being put into place where streaming compressed video is carried over g or a networks. The reality is that b/g equipment will be in use for many, many years. Today, the bulk of equipment manufactured and sold to wireless professionals is still b/g. IEEE a/b/g/n Wi Fi Standards and Facts Page 3

4 For those few who in the near future absolutely need higher data throughput for a particular application, then n might be a consideration. The n standard has been expected to provide data throughput of 100 Mbps or greater. However, real world tests, where building materials and existence of other wireless signals in the frequency band have resulted in data throughput rates of as low as 26 Mbps. There is also the risk of the product being outdated in a year should the specifications change through the IEEE working group. Thus the actual performance just might not be any better or much better than a high RF powered b/g device. If frequency interference and congestion is a significant factor, then a should be considered. However, not all client cards in computers, etc. have a capability and this should be evaluated carefully. In summary, most consumers or small businesses would be better off without any doubt with an high RF powered b/g device for the foreseeable future. Comparison of LAN Standards Standard Maximum Data Rate (Mbps) Typical Throughput (Mbps) Operating Frequency Band Maximum Non Overlapping Channels (Americas) b GHz g 54 8 (Mixed b/g) 2.4 GHz 3 *1 3 *1 25 (Only g) a GHz 24 (20 MHz channels) 12 (40 MHz channels) n *2 2.4 GHz & 5 GHz *3 *1 Channels 1, 6 and 11 are the three non overlapping channels in the Americas. Each channel is 20 MHz wide. *2 Actual throughput will depend upon various factors such as the manufacturer and model, environmental factors, whether 20 MHz or 40 MHz channels are utilized, if security is enabled and whether all clients are n or a mix of a/g/n. *3 For n, in the 2.4 GHz band, there are three non overlapping 20 MHz channels or one 40 MHz channel. The use of 40 MHz is not desirable or practical in the 2.4 GHz band. However, a single 20 MHz channel could be used with lower throughput, largely defeating the gain of using n. In the 5 GHz band, twenty four non overlapping 20 MHz or up to twelve 40 MHz channels exist. IEEE a/b/g/n Wi Fi Standards and Facts Page 4
