Top Adding - WiMax, VoIP, and the Metropolitan Area Network
The emerging IEEE 802.16 standard, commonly known as WiMAX, promises to deliver last mile wireless broadband internet access capable of carrying data intensive applications, such as VoIP and streaming video, to Metropolitan Area Networks, as well as sub-urban and rural communities. WiMAX is considered a disruptive technology, designed as an alternative According to USFDA, a combination product is one composed of any combination of a drug and device; biological product and device; drug and biological product to fixed line DSL and coaxial technologies, and with its 802.16e revision, the cell phone networks as well. Worldwide Interoperability for Microwave AXcess will operate over licensed and non licensed frequencies using non line of sight (NLOS) and line of sight technologies, extending broadband coverage to cities and towns wirelessly via a metro area network. Additional ; or drug, device, and biological product and fixed dose combination would include two or more combinations of drug. Examples of combination products may in , because of it’s far reaching capabilities and ease of implementation, wimax is the one technology likey to bridge the Digital Divide, connecting underdeveloped regions and sparsely populated rural areas much more cost effectively than deploying a wireline infrastructure. WiMAX and WiFi Compared The widespread adoption of the wireless LAN in the bus lude drug-coated devices, drugs packaged with delivery devices in medical kits, and drugs and devices packaged separately but intended to be used together. ness community, as well as the emergence of WiFi hotspots in public areas, airports, hotels and cafes, has been of tremendous significance in providing mobility to business people and consumers alike. Thanks to the open standards guided by the 802.11 committee and the WiFi Alliance, WiFi technology is becoming ingrained in our society. WiMAX plans to take WiFi a step fu here is enormous increase in the number of combination products entering the market in the recent years. Combination products have proven advantages but fixe ther. While the two technologies may sound the same, they are from their conception designed for totally different applications. WiFi is a short range standard that was designed primarily as an extension of the local area network (LAN) to provide mobility for the end user. It operates over unlicensed frequencies and has a range of about 100 meters, depending on obstruc d dose combinations are still in the process of convincing regulatory authority on their advantages over the single ingredient formulations. Combination pro ions. Typically one access point will be connected to a fixed line network, either a wired LAN or a DSL/cable broadband connection, and the range can be extended by adding more access points at appropriate distances. WiMAX, on the other hand, is designed to function as a carrier network, or a wireless Internet service provider (WISP), blanketing whole cities and region ucts have become life saving products for the pharmaceutical companies who doesn’t have many innovative molecules in their product pipeline and have been inc s with broadband Internet access comparable to DSL. Coverage in optimal conditions could reach 50 kilometers, but in reality are more like 5 km for users with NLOS customer premise equipment (CPE), or up to 15 km with a CPE connected to an external line of sight antenna. As the older more established technology, the 802.11 WiFi has been used in a mesh topology to cover easingly used in the product life cycle management. Even the companies having product patents are trying to extend their product life cycle through the combi larger areas such as college campuses and municipalities, for example to connect the terminals in police vehicles to their database. The emerging 802.16 WiMAX will be better suited for larger deployments, and will in fact compliment the private WiFi networks by offering a cheaper and more secure Internet access for data and voice applications. The WiMAX Standar nation products and maximize the revenues. But the companies involved in this practice are overlooking that they are burdening the patients both economically s: Fixed, Nomadic, and Mobile The 802.16 standard developed by the IEEE envisions a fixed wireless broadband network operating in the spectrum range of 10 GHz to 66 GHz. Originally, only the licensed spectrum was addressed in this range, and line-of-sight multipath technology was dealt with by adopting OFDM as the standard. Subsequent revisions added the 2 GHz and physically. They need to rightly judge the benefits of the combination products and they have to even look at the risks involved when combining the produ to 11 GHz band to the spectrum, and incorporated support for non-line-of-sight technologies and Quality of Service (QoS) techniques, a prerequisite for such time sensitive applications as voice and video. The revision known as 802.16-2004(d) rolled up all the previous revisions and then added some. Most of these original issues dealt with the Physical and Media Access ts. Some of the combination products were well accepted by physicians while others suffered. Companies involved in development of combination products are fi ontrol layers, and resulted in a standards list of optional and mandatory elements by which vendors could design their products. The resulting fixed WiMAX standard has a data rate of up to 40 Mbps, support for half and full duplex transmission, improved QoS, and the incorporation of multiple polling techniques, ultimately reducing packet collisions and overhead. Base ding difficulty in defining their combination products and facing various challenges from selecting a combination to marketing it. Following aspects would a stations are to support several different topologies, such as wireline backhauling, microwave point to point connections, and the ability for the WiMAX base station to backhaul itself by reserving a part of the bandwidth for that purpose. By design, 802.16d would cater to the residential and small business markets offering wireless broadband access with speeds comparab dd to the challenges in developing combination products: Which markets to tap where the combination products can do fairly well? Which combination prod e to DSL. Enterprise markets could be served at T1/E1 data rates. While this version of WiMax is called fixed, it is in all actuality nomadic. Users on a private WiFi network indoors could be passed off seamlessly to the publicWiMAX network when moving outdoors, their hardware determining the best network available. Devices on the WiMAX data network would include lapto cts are meaningful and rational? Which therapeutic categories to select? Which Combinations can address unmet needs of the patients? Do combin s, PDA’s, and smart phones equipped with an on board WiMAX capable chip or PC card, utilizing the spectrum for voice, data, video, and music transfers. Nomadic WiMAX provides for limited mobility in that the range of coverage is handled by the same base station. WiMAX Goes Mobile With the adoption of the 802.16e revision in late 2005, all the hype ha tions increase the patient compliance? What would be the developing cost? How to tackle the risks encountered during combination product developmen been on Mobile WiMAX, a technology designed to compete with the cellular networks.
With major support from manufacturers like Intel, Motorola, Siemens, and Nokia among others, mobile WiMAX is built on open standards and is purported to be 4 times faster than the cellular 3G technologies (EVDO, HSDPA). Significant cost savings can be achieved for voice applications b t? As combination products don't fit into the traditional categories of drugs, medical devices, or biological products, the USFDA is in the process of devel placing calls over the Internet through VoIP. 802.16e provides for fast and seamless handoffs between base stations, with a cell radius of about 3 miles, similar to cellular networks. The standard was ratified in late 2005, and real world applications are beginning to show up in 2007, with more robust development expected throughout 2008. Because this technology is s ping new procedures for reviewing their safety, efficacy and quality. Professional from academic institutions, pharmaceutical industries, health care indust uch a threat to the legacy telecommunications industry, it is no surprise that Sprint Nextel will be deploying WiMAX as opposed to EVDO in its 4G network. Sprint has been buying up much of the WiMAX spectrum, and has recently announced a partnership with Nokia to deploy WiMAX to four Texas cities by mid 2008. This is not their first WiMAX network, and telco’s around th y and representatives from various regulatory agencies are working out to design the regulatory requirements for manufacture and sale of combination products globe have been doing the same. The 802.16 standards are a work in progress, and as such, are subject to changes and revisions. As the standards committee works on the technology, the WiMAX Forum hopes to do what the WiFi Alliance did for the 802.11 standards, by promoting interoperability between components through testing, and offering WiMAX certification to vendors . As there is an increasing trend of the combination products companies manufacturing such products should be able to tackle the problems involved in the de that conform to the 802.16 standards. It should be noted that many of the WiMAX implementations at the time of this writing are proprietary, and thus do not necessarily follow the recommendations of the IEEE or the WiMAX Forum. The broadband wireless ISP Clearwire Communications has over 200,000 subscribers in 375 cites, and calls its service a “WiMAX-class solution, u elopment. They need to be wiser in analyzing the market trends and the regulatory requirements. Companies that provide selfless information through particip ilizing next-generation, non-line-of-sight wireless technology.” Other early adopters of pre-WiMAX technology are forging ahead, providing wireless broadband access to residential consumers and the small business market, with many companies climbing aboard the evolving standards bandwagon to assure interoperability and backwards compatibility of devices and applications tion in industry events and feedback to regulatory authorities would be able to face the challenges and will be successful in developing combination products
