Solution:

The Solution:
Osicom was able to provide a reliable, cost-effective solution by
implementing Optivision video networking equipment, operating on a
Gigabit IP backbone using existing fiber between the cities. The installation
is comprised of a main broadcast facility located in the city of Tangshan.
Coming out from the Tangshan is two fiber rings connecting each of 12
cities. The Northern ring is made up of the cities of Fengrun, Yutian,
Zhunhua, Qianxi and Luanxian. The Southern ring connects the cities of
Qianan, Fengnan, Tanghai, Leting and Luannan.

Re: IEEE 802.11xx, Wireless Data, Private Networks

Hi Scott,
Thanks for that informative post. At present I am limited to one puter, Medusa, which has 3 monitors, 3 video cards and one cable connection. I've been considering a laptop and your discussion of using 802.11 gear has just now completely turned me around on my plan, which was to use an Ethernet hub and cable system. What is the form factor on your laptop radio connection? PCMCIA? I'd love to get something internal if possible. The PCMCIA cards are just too fragile for a wild man like me, (or was that klutz?) Oh, whatever.

The reason I was curious about the 802.11a devices is to try to sort out Wi-Lan's niche in the spec battles. It appears to me that Cisco will be able to do its flavor of OFDM without paying a royalty to Wi-Lan. Comments welcomed.

Re: I live in a pretty rural area and so I'm actually looking at some point-to-point wireless radios for the link from my house to my office ... they are 900Mhz and have a range of 20 miles ... ~128kbps ...
I've looked at the Aironet line, and Breezecom. I'm curious as to which radio manufacturer you have chosen and what prompted your choice. TIA

Ciao, Ray

Scott, Ray re 802.11a vs 11b

I think you need to examine your understanding of the specifications. The 11a spec takes you to 54 Mbps...
and when it is placed underneath the ieee 1394 multimedia spec you get the philips multimedia set top boxes ( dual streaming audio/video (2 way videophone, or two concurrent "movies" , plus additional 2Mbps channels for further voice i.e. 3g cell phone bandwidth.)

They demo'd this last year ,and again in Jan at the consumer electronics show in vegas. These were reference designs - similarly avialable for a relatively small licence fee.

If you like the above description, then you need to (re)visit the Wi-lan site, and learn a bit about their strategy(s).

I frankly don't follow the intellectual property view that you were discussing. ( I don't understand exactly what you guys were saying).

The economic world does work well on the basis of core intellectual property being cheaply shared. This is true in cell phones, most printers since the laser printer, automotive components (bosch has a "lock" on fuel injection systems), and many kitchen appliances. To think otherwise is (imho) a bit bizarre.

On the cell phone in particular, qualcomm has the patent / ip rights on "cdma". It is very interesting to compare the
stock charts for qcom and WIN esp. since Dec when Cisco and Win had their litle dustup.

It sure looks like some big money moved out of QCOM. when they looked at the details.

Here is a link where I last saw this discussed:

eng.stockhouse.com.hk

Then this...

eng.stockhouse.com.hk

When you look at these you'll see that the qcom line (purple) touched the WI-LAN line right at the time of the whole Cisco / wi-lan takeover "our ofdm is better than yours" fracas in December. Since then Qcom has been soft, and if you read SI:qcom you'll see a lot of shareholders saying "what's going on?".

The bollinger bands are relevant because they define standards of deviation from a trailing price. QCOM went out the sidedoor a month or so ago...

If the logic of patents holds no weight for you, perhaps the associative synchronicity of these events will catch your eye.

Cheers!
