The Salisbury Zoo & Wireless Internet Access


My source tells me that the ethernet cable has degraded due to the elements. It sounds like somebody didn't install the cable properly (probably buried it in the ground), and it's gone to hell and no longer serves the purpose of passing data traffic between buildings (you've seen info on "slow uploads" which confirms this). The right way to do this would be to use conduit to provide all weather protection. Obviously, this would have been a lot more expensive to do the job right. Once again, the region's desire to do things cheap costs more money in the long run. Was it cheap in house labor with no technical supervision, or the lowest bid? Who knows...

There is a chance that the cable was run a long time ago, and was CAT5 and not the CAT5e cable that is typically used today. If that's the case, upgrading the infrastructure is probably a good idea. I'm not sure what was done, with what cable, or how. These are just guesses on my part.

To avoid the expense of properly running the cable (and perhaps to offer additional functionality in the future), somebody made the decision to make wireless connections between the buildings. Whether this is also supposed to provide wireless throughout the zoo for staff, I'm not quite sure. My guess is no, because I'm told the equipment proposed would operate on the 802.11a standard. This standard operates on a less polluted frequency (good thing), but typically a notebook would only have a range of about 50' in a typical office environment. Some newer notebooks don't even have 802.11a radios in them to save a few dollars for the manufacturer.

I was told that this system is *not* intended to provide Internet access to visitors. And using the 802.11a standard, I doubt that employees would really cover a lot of ground using this system.

It seems a shame to spend this kind of money for wireless networking, and not give the zoo keepers "anywhere" access to zoo records that might assist in improving standards of care for the animals.

The fact that the Zoo already purchased the equipment before going to the City Council clearly shows Alessi's arrogance and disregard towards the rules. I'm probably going to ask for the actual bid process and figures because they didn't bid this out either. Not through the Newspaper and so forth. Time will tell once again.

How did I do Mr. Micciche?

Actually Cat6 would be used today between buildings, if not fiber. Cat5e would have been used a few years ago.

I should add, the equipment they are getting works on A, B, and G. So old equipment they have that is A will still work, and new G equipment will work. Really wireless is better in a situation where employees are out in the field with laptops at the different cages and buildings. It's cheaper than running wire to each different building.

Also, the router they are using is the cheapest they can go, so they arn't spending as much money as they could. If they wanted to spend a ton of money, all the equipment would be Cisco.

And about the bidding it out, it looks like it has, as those prices are in line with other internet prices.

I agree Anon, but what have you to say about the radius? How many routers would be needed to create wireless access over the entire zoo area? Since I don't know this stuff, I'm not trying to be smart, just trying to get educated and get the facts.

Indoors you should be able to get 200 feet with 802.11a and 450 feet with 802.11b/g.

Outdoors you would be able to get 450 feet with A and 650 feet with B/G.

All the above are in optimal situations.

Placing the radios in the Zoo would really depend on what A/B/G equipment is where. Some may be placed closer than others.

I'm not sure where Joe's 50' came from. The outdoor equipment proposed runs on A/B/G, while the indoor router runs on B/G.

From personal experience I have no problem with B at 200' through 2 concrete walls. And G at 100' through about 4' of reinforced concrete.

Since when has doug church been an expert at pulling cable? he leaves his equpment dangling from the ceiling.

slow uploads are from over crowded temporary files & "cookies".
if the cable is bad, uploads won't occur at all

I thought I understood that the Zoo had cable, therefore they have high speed access, so what's the problem?
