About This GuidePreface This guide was created to help you understand the philosophy behind Motorolas Enterprise Wireless LAN (EWLAN) products. This guide is intended for those interested in familiarizing themselves with the Enterprise wireless offerings available from Motorola. Additionally, once familiar with Motorola’s solution set, this guide also explains how to plan and assist in the deployment of your wireless network in respect to emerging standards and technologies. Once you have thoroughly reviewed the content of this Enterprise WLAN Design Guide and applied it theoretically to the new 802.11n standard (as described within 802.11n), you will have all the pre-requisite knowledge required to plan the replacement of an existing wired network and deploy an Enterprise-class wireless network. NOTE: Please keep in mind, successfully deploying a wireless network is directly related to successfully defining the user requirements, physical obstacles, growth expectations and emerging technologies both impacting your deployment now and in the future. The guidelines set forth within the guide will help prepare you to ask the right questions when faced with these decisions. The graphical interfaces of Motorola’s Enterprise WLAN products are designed intuitively. With just some basic knowledge of 802.11 wireless technology, you can plan, deploy and manage your infrastructure. All of Motorolas EWLAN products follow this philosophy of keeping things simple to optimize your deployment. Motorola has observed that trying to push through your own Command Line Interface (CLI) is not really the best thing to do when you know there is a very strong CLI becoming a standard in the industry. Therefore, Motorola is moving its products to this type of CLI. To date, the WS5100, RFS6000 and RFS7000 are already using Motorola’s proprietary Wireless Next Generation (Wi-NG) technology.Document Conventions The following conventions are used in this document to draw your attention to important information: NOTE: Indicate tips or special requirements.

Additionally, once familiar with Motorola’s solution set, this guide also explains how to plan and assist in the deployment of your wireless network in respect to emerging standards and technologies.A good wireless system design entails the following:• A site survey • Channel mapping • An understanding of the construction of the building • An understanding of where RF coverage is required • The esthetical position (corridors, isles and coverage area blockages)• The number of users per AP• The required throughput per user• The distance from an AP to the LAN’s entry point• Power supply options• Security options• The location of the Radius Server (acceptable RTT yes/no)• Understand if the applications are wireless ready NOTE: Many protocols are designed for a wired environment where there is almost always a connection between the terminal and the server, whereas in a wireless environment the terminal can go in and out of RF coverage or go into sleep mode and loose its connection with the server.A proper site survey is much more involved then just measuring RF coverage. That is why a more appropriatedescription might be system design.

WLAN Reference Architectures2.1 History and Innovation No entity has a stronger heritage in wireless than Motorola, and with the acquisition of Symbol Technologies, no one else can claim as much experience, innovation, or intellectual property in wireless communications. Motorola has been involved in RF for over 75 years, significantly longer than any of our competitors have been in business. • Motorolas wireless communication systems were used by the Apollo astronauts when man first stepped on the Moon • Motorola is chosen more often than any other vendor for large scale, secure mobile communications systems at international events like the Olympics, NFL games and NATO Summits • Motorola was the 2006 winner of the National Medal of Technology - Americas highest honor for innovations • Motorola is a two time winner of Malcolm Baldrige Award - US Governments highest quality award • Motorola is a leading provider of mobile data communications in the State & Local and Federal Markets Symbol Technologies was the leader in WLAN innovation, with a long list of industry firsts and contributions: • 1989: Brought to market the first commercial WLAN - the Spectrum 1 • 1993: founding members of the IEEE 802.11 committee • 1998: Introduced the first wireless VoIP handset - the NetVision phone • 1999: Founding member/chair of the Wi-Fi Alliance • 2002: Invented the WLAN switch (controller) architecture • 2007: Began shipping the industrys first RF switch (the RFS7000)2.2 WLAN Market Leadership Motorola is the best kept secret in WLAN infrastructure solutions. Many of our prospective customers are not aware of our position in the marketplace. If we have a weakness in our past, it certainly isnt technology, but rather our focus on marketing it. Motorolas customer base includes many of the world’s largest retailers, health care institutions, transportation companies, and manufacturers - to name a few - all of whom rely on a Motorola backbone for their mission-critical mobility needs. Billions of dollars in business is transacted across our networks every
2-2 WLAN Design Guide year. If the stores or distribution centers of just one of our largest customers were to go down, there would be a very real material impact on the world economy. A few facts: • Over 100,000 WLAN switches sold - 2 times more than Cisco, the next closest competitor • #1 or #2 in WLAN revenue in many key vertical markets: retail, health care, manufacturing, transportation and logistics. Bottom line: we win where we play. • Largest WLAN deployment in the world with 100,000 APs and over 10,000 switches • Largest wireless VoIP deployment with 40,000 Spectralink phones on our WLAN 2.3 End-to-End Motorola provides the most comprehensive end-to-end Enterprise mobility solutions available in the market. Why is this important? CIOs increasingly like to buy from fewer and fewer manufacturers. They want fewer vendors in their account - thus, fewer necks to squeeze when there is a problem. Additionally, they want solutions that work well together, and thus are more easily managed and secured. Solutions sourced from a single vendor are far more likely to work together seamlessly. Motorola offers solutions that span the entire range of Enterprise mobility. From where the network cable terminates, to the palm of the hand and beyond, from wireless infrastructure indoors and out, private networks and mesh technology, to mobile computing, advanced data capture, RFID, and management and security software, Motorola provides complete end-to-end Enterprise mobility solutions that no other single vendor can match. Our competitors can easily be reduced to one-trick ponies or simply blue wire or plumbing. No one offers the industry expertise, or the breath of solutions and technology to provide true mobility. Motorola is a leader in the various aspects of mobility: #1 in mobile computing, data capture, RFID, wireless broadband, two-way radios, and push email. 2.4 Edge Versus Core Imagine for a minute the entire ecosystem of IT investments that one of your prospective customers will make to mobilize their business. The list is long, but it minimally includes: IP Core Access Networks Clients, Switches, WLANs, Mobile Computers, Routers, Cellular, Rugged Laptops, Firewalls, WiMax and Wireless VoIP Handsets Motorola focuses on wireless networks and client devices. We have tremendous experience in mobility and our portfolio includes a strong set of solutions focused on the network edge. Our competitors, on the other hand, tend to focus on the core, or even worse, only a single element in the ecosystem. To provide true mobility, a vendor must understand every piece of the mobile edge. How will your devices roam - between APs, indoors to outside, or from WLAN to WiMax? Can you manage your WLAN network and point-to-point broadband network seamlessly? How will you secure your mobile infrastructure and devices to ensure regulatory compliance and protect sensitive information? Motorola coined the phrase Enterprise mobility by being the first to truly unwire the Enterprise and enhance productivity for the mobile worker. Doing so, required enormous amounts of innovation and expertise. A mobile environment requires a unique level of management, security, and control. Through a broad portfolio of wireless infrastructure solutions (not just WLAN), as well as market leadership in mobile devices, only Motorola truly understands mobility throughout the mobile edge.
