Achieve a pragmatic realizing of the underlying innovations of the 802.11n general and the methodologies for finishing a winning instant community installation
Practical, start-to-finish suggestions for profitable deployment of 802.11n instant LANs
With the ratification of the 802.11n instant LAN general, millions of businesses are relocating swiftly towards implementation. even if, 802.11n is particularly diverse from legacy 802.11a, 802.11b, and 802.11g instant criteria, and winning deployment calls for new wisdom and strategies. during this booklet, major instant professional Jim Geier systematically offers the entire info and suggestions that community architects, engineers, directors, and executives have to maximize the functionality and enterprise worth of latest 802.11n networks.
Drawing on large event with real-world 802.11n deployments, Geier publications you thru the total undertaking lifecycle: making plans, layout, set up, checking out, tracking, and aid. each one section of instant LAN deployment is equipped into basically outlined steps, and a number of case stories and hands-on routines express the way to practice each one procedure.
You’ll locate sensible information for deploying in corporations with no current instant infrastructure, in addition to migrating from legacy 802.11a, 802.11b, or 802.11g networks. For handy reference, Geier additionally offers an intensive, updated instant networking word list.
Jim Geier based Wireless-Nets, Ltd., and serves as its important advisor. His 25 years of expertise comprise research, layout, implementation, install, and aid of instant network-based suggestions for towns, companies, airports, brands, warehouses, hospitals, and different amenities around the globe. he's writer of greater than a dozen books, together with instant Networks - First Step and Deploying Voice over instant LANs (Cisco Press) and imposing 802.1X defense suggestions. He has been energetic with the IEEE 802.11 operating workforce constructing overseas instant LAN criteria, and chaired the IEEE foreign convention on instant LAN Implementation.

Some cellular phones incorporate VoWLAN capability, which allows users to make calls over traditional cellular networks when no WLAN is available and then switch to a WLAN seamlessly when the user roams onto the Wi-Fi enabled network. Figure 1-1 illustrates the basic usage models of a VoWLAN system. The optimum approach depends on user requirements and existing telephone hardware. Facility (a) (b) Internet (c) PSTN Figure 1-1 VoWLAN Usage Models: (a) Local-Only, (b) Telephone via Internet, Telephone via PSTN Case Study: USC University Hospital At the USC University Hospital, as with other hospitals, doctors and nurses must have immediate contact with each other to quickly implement solutions for patients.
Hospitals were one of the first users of wireless IP phones, mainly because of the significant needs for effective communications among high-valued medical staff. The ability for doctors and nurses to respond quickly with verbal instructions is crucial for saving the lives of patients. Patients receive a higher level of care, which leads to faster recovery. Wireless IP phones allow hospital staff to not waste time looking for a phone to use. An issue with deploying voice over wireless solutions in hospitals, however, is the difficulty in providing adequate WLAN coverage.
In addition, an LBS enables hospital staff to track the whereabouts of patients, and if they go astray or anything adverse happens to them, an alarming system will alert the closest doctors and nurses. For example, some homes for the elderly implement LBSs over WLANs to trigger an alarm when patients try to leave the facility. Hospitals also need to track expensive equipment that is often required to save lives. An LBS enables hospital administration to know the exact location of this equipment for accountability and usability purposes.
