Re: Question for designers (WLAN) [7:59216]
There is another wireless technology instead of Aironet. Aironet use 2.4 Ghz band. The other technology is Canopy, made by Motorola. It uses 5.3 Ghz or 5.8 Ghz band, and it is 802.11 too. Check it. It4s no expensive and works good. http://www.motorola.com/canopy/html/equip.html Regards, Ing. Joseba M. Izaga K|hn Gerente de Operaciones Alfanumeric, S.A.

RE: Question for designers (WLAN) [7:59216]
If your not going to run 802.11a then there might not be a significant advantage to going with the 1200 series AP. However, hospitals normally have a lot of long hallways that are perfect for using a patch antenna. (A lot of times you can cover an area with one diversity 6.5dBi patch that might take 2 1100 series APs to cover otherwise.) The external antennas would probably be the biggest advantage of going with the 1200 series vs a 1100 series for you. Other than that... there aren't very many differences.

Forgot to ask... what country are you from? I know some countries put restrictions on the power and antennas that are available.

It's a godsend given how badly some of the Docs write. MikeS Have you looked at the new DEA requirements for electronic prescribing of controlled substances? Now, I'm not saying these apply to a simple system that just prints the prescription at the front desk, but those that electronically transmit things that will go to an outside pharmacy. Extensive security requirements, including PKI, time synchronization, audit, etc., that may be marginal for a Palm. In some respects, it's even more challenging to be more than just an electronic prescription pad. There are great numbers of medical variables, even if you've got the drug name straight. I've been working on some expert systems for prescribing cardiac drugs, and it isn't a simple process. Yet other challenges come from the influence of insurers and other third-party payors, who may have a formulary of which drugs in a class they will allow, or allow under certain circumstances. There are quite a few plans that first require the doctor to certify either that over-the-counter NSAIDs (nonsteroidal anti-inflammatory drugs, such as ibuprofen and many prescription drugs) have been used, or there is medical necessity for a specific prescription NSAID. There are six chemical families of NSAIDs, and the insurer may want you to use only one in each family -- and different insurers have different requirements. Other insurers have requirements such as allowing the prescribing of the much more expensive angiotensin-2 receptor blockers for high blood pressure, only if three separate (and cheaper) angiotensin converting enzyme inhibitors have been tried and failed. In other words, real-world prescribing is going to start needing lots of data base interactions. Howard C. Berkowitz wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]...

Re: Question for designers (WLAN) [7:59216]
Be prepared for alot of *fun*... more so when you get near the Cathlab or any type of MRI imaging. These things generate ALOT of noise. So do your site audit when they are running. Also, some monitoring equipment can be interfered or cause interfence.. neo-monitoring comes to mind with the wireless strip recorders. Some facilites use an inhouse phone/intercom system that can interfere. Some surgery suites now have wireless links for video and/or data. Not to mention the odd rogue AP that some decided was a good idea to add more workstations when they ran out of cable. I think you see the pattern of audit EVERYTHING and do it during the day when things are running. If you plan to run some in the basement (why is it the IS dept is always in the basement?) be prepared to have lousy coverage unless you overbuy the antenna count. Structual steel in the columms wreak havoc with the signals and not to mention all the rebar in the walls. You can get around some of this with doing some simple mods to the antennas of the APs. A simple mesh reflector can help punch through a wall.. or focus the signal down the hall to skip a AP in the middle of the hall. This is just an example. You will probably end up with an assortment of antennas.. patch, dipoles and the normal AP mounted antenna. Buy good equipment. The cheapo stuff has alot of troubles with the radiated noise, not to mention the lack of support. These are my opinions.. your milage will vary ;) MikeS -- Tutorials - Whitepapers - Security - Wireless- News Find me at www-dot-packetattack-dot-com David j wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]...

Re: Question for designers (WLAN) [7:59216]
Yeah, of course, the same here, this is one of the reasons why money is not a problem (well, at least not a big problem). We already have a data network and now that we're thinking about wireless we want a robust, very secure and useful solution. I have been studying MikeS response and I can conclude that it's better to spend money in good quality devices, but the only remarkable difference between Aironet 1200 1100 that I can found is antennas, the 1200 series has several options and 1100 only has only an omnidirectional integrated antenna. If I'm not going to use 802.11a, I can see any reason to spend more money buying 1200 or 350. What do you think?
