Wireless Lan Connecting People, Space and Technologies to Evolve the Federal Workplace What Is Wireless LAN? U.S. General Services Administration ALL ABOUT . WIRELESS LAN connecting people, space and technologies to evolve the federal workplace what is wireless LAN? A wireless local area network (WLAN)—a key element of any mobility strategy— is part of the IT infrastructure that enables mobile connectivity. With WLANs, users can connect to mobile devices such as laptops and cellular phones wirelessly to the agency Local Area Network (LAN) and access corporate and Internet-based applications whether they are in their office, a conference room, or any other location inside their agency’s workspace. Wireless access points within a federal office complex allow employees to disconnect from their desks and be more productive. Having a robust wireless network enables employees to be mobile with all their wireless devices. It can improve utilization of common space and meeting rooms and lead to enhanced collaboration among coworkers. what equipment is required? Wireless LAN equipment is divided into two categories: wireless access points and wireless LAN controllers. ● Wireless access points connect the user devices to the local area network. Typically, these provide users a 5Mbps connection based on the IEEE 802.11x standard. To ensure a 5 Mbps connection per device, one access point is needed for every 10 wireless devices. ● Wireless LAN controllers provide the configuration management for each wireless access point. Depending on the features of each access point and controller and the performance requirements of the network, one controller may manage as few as 10 access points and as many as 100. WIRELESS LAN . FEATURES what are some wireless LAN implementation options? Before buying anything, federal agencies must consider their existing infrastructure base, user communities, and capabilities to effectively operate wireless LAN infrastructure. Four implementation options include: ● Extension of existing LAN: This adds wireless LAN infrastructure to an existing LAN. The LAN is operated and maintained without a change in operating model, and this is the most typical model. ● Deployment of a new LAN: This could be for new locations, new organizations, or building expansions. Operating model can be either government or contractor owned/operated. ● Leased Equipment (Government Owned): A contractor leases the equipment to a federal agency. As part of the lease, engineering, installation, and operating may be included. ● Service Purchase: Rather than buying or leasing equipment, a federal agency buys a service and is not concerned with the equipment or operation; instead, a service-level agreement is maintained. what are wireless LAN security features? When implementing WLAN, security policies and procedures must be addressed: Who can access the network? Will there be a separate guest network access? What type of Internet and local network access will users have once access is granted? How will the guest network be filtered? Will some Web sites be blocked, and if so then how? Security for LANs encompasses these three areas: ● Authentication: The mechanism that identifies devices and/or users before access is granted. Since most devices can pick up the signal of wireless access points, authentication is the first gate to prevent unauthorized access. ● Encryption: The mechanism that protects the confidentiality and integrity of data. Generally, wireless access devices use a mechanism called Wi-Fi Protected Access 2 (WPA2) to encrypt data in WLANs. ● Intrusion detection and prevention: The mechanism that detects and blocks unauthorized users attempting to access a WLAN. Typically, authentication is built into the existing LANs but intrusion detection and prevention systems often must be purchased separately. Sometimes, these purchases are from vendors different than the equipment suppliers. GSA can help you secure the right levels of encryption and any engineering services needed to assist with the wireless design, procurement and implementation. 2 WIRELESS LAN . PROCUREMENT VEHICLES which GSA procurement approach is best? WorkPlace+ specialists can guide you through the GSA resources and procurement options to acquire components of a wireless LAN. Typically, four factors are considered: ● Cost of the good or service, including acquisition transaction cost ● Speed of the acquisition ● Flexibility of the acquisition ● Access to competent suppliers GSA will help you create the contract, reviewing both “full and open” acquisition and pre-competed contract options. GSA studies have shown that “full and open” acquisition is a longer process. Even among the smallest acquisitions, several months are required for task order completion. By comparison, pre- competed contracts produce task orders in a matter of weeks, while also minimizing the risk of a contract protest. Pre-competed GSA acquisition solutions for wireless LAN are available through Connections II or IT Schedule 70, depending on your agency’s needs. For agencies that are in need of end-to-end support through the full LAN development cycle, Connections II is best. Schedule 70 is best suited for agencies that have pre-existing LAN infrastructure. See the chart below for the pros and cons of each option. ACQUISITION ACQUISITION ACQUISITION ACQUISITION BEST USED FOR SUPPLIER POOL VEHICLE COST SPEED FLEXIBILITY Full System 21 suppliers; Connections II Development Cycle; Competitive High High all focused on “Green fields” WLAN WLAN components; Most federal either equipment or Supplier suppliers; Competitive Medium Schedule 70 professional services; Dependent focused broadly security on IT 3 WIRELESS LAN . ACQUISITION what should you consider in acquisition? Regardless of how the LAN will be implemented and operated, GSA’s WorkPlace+ team will help you evaluate four important factors in the procurement process. They will assist your agency in evaluating solutions that Contact Us: best meet the current and future workplace needs: Sharon Wall ● User Experience: Includes per user performance, user categories, 617-565-5760 applications required by the user, and where connectivity is required. [email protected] ● Wireless Environment: The physical environment where the wireless signals will be propagated. ● Wired Connectivity: The wireline connectivity to the wireless access points. ● Network Application Services: The most important factors to consider as part of the decision to implement a wireless LAN infrastructure are network management, configuration management, accounting, performance and security. ● Other: Site surveys, service level agreements, and equipment or service agreement upgrades. Resources: gsa.gov/schedule70 why move ahead with acquiring a wireless LAN? gsa.gov/connectionsii Incremental investments in technology such as WLAN can enable employees to be more productive by not being tied down to a desk location. Facility managers can build collaborative work locations and employees can work, online and in real time, without necessarily being at an assigned desk. As work spaces are expensive and many current workplace utilization averages are low, mobility is a key factor to allow for fewer work spaces and greater utilization of existing ones. Wireless LAN is comparatively inexpensive. GSA estimates that the capital investment in wireless LAN equipment can be as low as $33/ device/per year, assuming a three- year equipment life. This is far less expensive than the cost of inside wiring to connect each desktop computer and telephone. 4 .

  • Analysis of Wifi and Wimax and Wireless Network Coexistence
    International Journal of Computer Networks & Communications (IJCNC) Vol.6, No.6, November 2014 ANALYSIS OF WIFI AND WIMAX AND WIRELESS NETWORK COEXISTENCE Shuang Song and Biju Issac School of Computing, Teesside University, Middlesbrough, UK ABSTRACT Wireless networks are very popular nowadays. Wireless Local Area Network (WLAN) that uses the IEEE 802.11 standard and WiMAX (Worldwide Interoperability for Microwave Access) that uses the IEEE 802.16 standard are networks that we want to explore. WiMAX has been developed over 10 years, but it is still unknown to most people. However compared to WLAN, it has many advantages in transmission speed and coverage area. This paper will introduce these two technologies and make comparisons between WiMAX and WiFi. In addition, wireless network coexistence of WLAN and WiMAX will be explored through simulation. Lastly we want to discuss the future of WiMAX in relation to WiFi. KEY WORDS WiMAX, WiFi, wireless network, wireless coexistence, network simulation 1. INTRODUCTION With the development of multimedia communication, people need wireless broadband access with higher speed, larger coverage and mobility. The emergence of WiMAX (Worldwide Interoperability for Microwave Access) technology met the people's demand for wireless Internet to some extent. If wireless LAN technology (WLAN) solves the access problem of the "last one hundred meters", then WiMAX technology is the best access solution of the "last mile". Though WiMAX is an emerging and extremely competitive wireless broadband access technology, the development prospects of its market is still unknown. Hybrid networks as a supplement to cell based or IP packet based services, can fully reflect the characteristics of wide network coverage.

  • Wireless LAN/MAN Modem Product Directory
    Wireless LAN/MAN Modem Product Directory Compiled by Barry McLarnon, VE3JF. Please send comments, corrections and additions to [email protected]. Introduction After a long hiatus, I've started working on updating these pages again. Currently I'm concentrating on checking the vendor info and URLs, and then I'll get more into the product data and other stuff. I've dropped the color coding to highlight changes, as it was too much of a headache to maintain. Instead, I'm keeping a in which I'll record the changes as I make them. This is a survey of currently available wireless RF modem products suitable for wireless LAN and MAN applications. At the moment, this survey includes only those products which are suitable for unlicenced operation in the ISM bands: 900 MHz (902-928 MHz), 2.4 GHz (2400-2483.5 MHz) and 5.8 GHz (5725-5850 MHz). Some of these products are intended for very short range wireless applications, while others are designed to be used as longer-haul point-to-point wireless bridges, and some can be used in either role. No attempt has been made to differentiate between these usages in this survey. Also, I don't necessarily list every product in each vendor's wireless product line. Some product lines have many different variants, and the tables would get too unwieldy if I tried to list them all, but I try to include some representative products from each manufacturer. I tend to omit the "access point" products, and products in which the WLAN modem is integrated into something else, such as a portable computer.

  • 87.35 Wireless Local Area Network (LAN)
    BUSINESS POLICIES AND PROCEDURES MANUAL INFORMATION SECURITY 87.35.1 New 7-20 Information Technology Services 509-335-4357 Wireless Local Area Network (LAN) Management OVERVIEW Wireless networks allow for accelerated delivery of network connectivity at a lower cost than traditional wired networks. Because of this, wireless networks have overtaken wired networks in terms of total data transmitted and have become a cornerstone of digital service delivery. Wireless networks present unique challenges in their administration, including the following: • Shared Spectrum – Wireless data networks using the IEEE 802.11 specification operate in the 2.4 GHz or 5 GHz radio spectrums. Both frequencies must be shared by all applications utilizing them in the same coverage area. This can be a problem if adjacent departments in the same building or area independently operate wireless local area networks (LANs). Problems may also be caused in the 2.4 GHz spectrum by other competing applications, such as microwave ovens or some cordless telephones. • Nonoverlapping Channels – Both frequencies are limited by the number of nonoverlapping channels that are available with the 2.4 GHz frequency limited to only three nonoverlapping channels and the 5 GHz frequency limited to 23 nonoverlapping channels. • Security – Wireless networks have unique security requirements to prevent rogue devices from connecting to, or interfering with, the WSU network. For the above reasons the following requirements are necessary. See BPPM 87.01 for definitions related to this section. Purpose The wireless LAN policy (BPPM 87.35) provides assurance of the security and operability of the wireless LAN segments thought out the University. Scope This policy applies to all institutional business units, workforce members, and institutional information systems that collect, store, process, share, or transmit institutional data.

  • Wireless Communications PURPOSE the Purpose of This Policy Is to Define Connection to the District’S Network Through Wireless Networking
    Effective Date: 10/23/2019 Fifth Judicial District Authorized By: Department of Correctional Services Policy and Procedural Manual Jerry L. Evans, District Director Fifth Judicial District Division: Administration Policy Code: Department of Correctional Services Unit(s): District Wide Public Access Policy Number: A021 Subject: Wireless Communications PURPOSE The purpose of this policy is to define connection to the District’s network through wireless networking. These standards are designed to minimize the potential exposure of the District from damages which may result from unauthorized use of District resources. Damages include the loss of sensitive or confidential data, intellectual property, damage to public image, damage to critical District internal systems, etc. SCOPE This policy applies to all District employees, contractors, vendors and agents with a District issued computer and other equipment used to connect to the District network. BACKGROUND With the Institute of Electrical and Electronics Engineers (IEEE) ratification of the 802.11b standard for wireless networking in 1999 and the subsequent proliferation of interoperable, affordable products that support that standard, wireless LAN technology (WLAN) has established itself as an important complement to the traditional wired data network because of the mobility they provide. 802.11b WLAN technology is also beneficial for gaining network access in locations that are difficult, expensive, or inconvenient to wire. Examples include outdoor areas, conference rooms, rooms with solid walls (to avoid running cables in unattractive surface-mounted conduit), and structures with asbestos, and historical buildings with strict regulations governing modifications. Despite these advantages, 802.11b WLANs have their limitations. For example, they are an order of magnitude slower than wired LANs.
