Superconducting Filters In Base Stations And Other Network Optimization Td’s Role

0 Introduction Superconducting technology is considered of strategic importance in the 21st century high-tech one, in energy, information, transportation, instrumentation, defense and other aspects important applications. Currently active in the world are in the application technology of superconductivity.

Superconducting filter using conductor at very low temperatures (-200 or so) when the conductor made of resistance similar to the principle of zero band-pass filter, used in mobile Communicate Base station receiver front end, significant improvements Mobile base stations Uplink performance, improve base station receiver sensitivity and lower band, the band all kinds of interference, thereby improving the signal transmission quality, extend coverage up to enhance signal transmission rate.

Of superconducting filter in TD-SCDMA base stations and other network optimization in the role of China is actively developing TD-SCDMA system and the 2G network optimization system is important.

1 mobile communications uplink and downlink analysis

1.1 Mobile communication is mainly limited by the uplink

Mobile phone base station transmit power is much greater than transmission power, and mobile phone base station receiver sensitivity and receiver sensitivity is almost the same. Therefore, mobile communication is mainly limited by the uplink, uplink coverage area are often less than the downlink coverage area.

In addition, as users continue to increase, mobile communication network is bound to increase the number of base stations. This allows access to the base station receiver interference and noise growing and increased the burden on the uplink.

1.2 to improve the general approach to the uplink

General approach to improve the uplink are: installation of the base station transmitter output cavity RF filter to suppress the base station transmitter spurious radiation. Base station receiver uses diversity reception mode, and also used in the RF input of the cavity filter to improve the receiver sensitivity and inhibit a variety of band interference.

However, the filter cavity Q value can only be reached around 5000, relatively large passband loss, stop-band attenuation is not enough, the transition zone are not steep. Therefore, this method can not effectively solve the problem uplink interference, the base station receiver in-band interference and background noise is still relatively high, the base station receiver sensitivity and capacity utilization is not high.

2 superconducting filter is the best way to solve one of the base station interference

Superconducting filter is to use conductor at very low temperatures (about -200 ) resistance is approximately zero when the surface characteristics of the filter is made, the Q value of up to 10 million, higher than the filter’s Q value cavity nearly 20 times. Therefore, the superconducting filter passband with minimal insertion loss ( 60dB) and very steep transition zone (-100dB/400KHz). After the superconducting filter

with the same working conditions in the ultra low-noise low-temperature release (LNA) (Gain: 12dB), with very low noise figure (

Did You Know That Drinking Water Stations Can Endanger Your Health?

While there has been concern over tap water for many years, it has become apparent that what comes out of the faucet is contaminated and often, very dangerous. Obviously, with water containing a variety of dangerous chemicals and parasites, many people are now choosing drinking water stations. These systems are commonly found in businesses, schools, medical facilities, and even homes. However, what you need to know is that these systems are actually contributing to the problem.

Unfortunately, most stations are unsafe. The reason is that the water is actually contaminated, coming straight out of the tap. Unfortunately, unsuspecting people take a nice, long drink as an alternative to tap water, believing they are taking steps to a healthier life. However, unless the station is from a reputable company, one that guarantees that only 100% filtered or mineral water is used, chances are people are drinking nothing more than tap water that is loaded with chemicals, parasites, and other dangerous contaminants.

The only filter these drinking water stations have is the basic carbon system. Yes, this type of filter can eliminate some of the harmful chemicals found in standard tap water but the truth is, they are not sophisticated enough to filter out everything. That means harmful chemicals, parasites, and other contaminants are being consumed, such as chlorine, lead, parasites, and more.

Even worse, these special water systems are designed with polycarbonate containers. This means in addition to the carbon filter eliminating only some of the dangers, the plastic container itself promotes additional health risks. New studies have shown that plastic, which is made from chemicals, can be very hazardous. For instance, when food is heated in a plastic container in a microwave, chemicals are released into the food. The same is true for these stations in that water being stored within plastic containers only further promotes contamination.

Okay, if you are like other people, you want to know how to eliminate dangerous chemicals, parasites, and other contaminations altogether. The answer is actually quite simple. The key is to avoid water from stations and choose only what has been filtered at home with an installed purification system. In this case, you could easily take fresh, clean, and safe water to work, while also having confidence that you and the entire family are consuming something at home that is pure and safe.

The good news is that filtration systems on the market today are beneficial for purifying contaminated water. Of course, you want to choose the right system, not one that uses a simple carbon filter. These systems come in three primary options that include the faucet system, the countertop system, and the under-counter system. Choosing a filter system that uses a high-density ceramic filter ensures that even the smallest contaminates are trapped. That way, contaminated water is a problem solved. You should take time to learn about the actual dangers found in what comes from the tap, as well as details on the top of the line filtration systems so you stop the danger!

Chilling Out in Nepal – Hill Stations, Lakesides and Much More

Most people associate Nepal with trekking, rafting and the likes, but for those relaxed travelers that don’t take a fancy to trudging through the mountains or getting their heart pounding in Nepal’s adventure sports, don’t forget there is also a tranquil side to this Himalayan paradise as well. Yoga, meditation, Buddhist tours, festival tours, golfing holidays, Thangka Painting schools, romantic honeymoons, Nepal is certainly much more than an adventure play ground. Spend a week or two here chilling out in some of the Hill Stations like Daman, Chisopani, Bandipur and Nagarkot or Pokhara’s tranquil lakeside and you will soon find that life here runs to a very different tune. If you want a more relaxed holiday or retreat get in touch with us today and let us arrange your own very special chilled out tour of Nepal.

Chill out destination’s in Nepal

Nagarkot – A popular tourist destination that people use as a quick stop off to view the spectacular Himalaya. There is a lot more to this magnificent Hill Station than just that. You can enjoy secluded retreats and hotels where you can get away from it all, enjoy revitalizing massage, rekie, mediation or just spend your time exploring the hillside villages. Nagarkot is within easy reach of Kathmandu, Nepal’s thriving capital city, in facts it’s an ideal place for a weekend city escape. In Nagarkot, there is also much more to do than just admiring the Himalaya, take a guided off road motor bike tour to experience the rich culture of the Tamang people, pony ride or hike to some nearby villages, go bird watching in the jungle or tackle and exhilarating downhill on mountain bike.

Bandipur – Half way between Kathmandu and Pokhara you can find this sleepy hill station high up on a ridge above the Marsyandi River and the orange growing regions. This one time isolated town is one of the finest examples in Nepal of how eco and social responsible tourism can work to create a wonderful experience for visitors and a profitable one for the villagers. Here you can explore the biggest caves in Nepal, see silk making first hand or just soak up inspiring views of the middle Himalaya. Visits to Bandipur can be arranged on the way to or from Pokhara and they can be combined with trips to Manakarmana, one of the holiest temples in Nepal and the only cable car ride the country has to offer. In Bandipur accommodation varies from first class mountain retreats to basic yet rewarding village home stays.

Bhaltali – Yet another example of tourism working for improved villages in Nepal. This hidden valley is a remarkable place, hemmed on one side by a river gorge and pine forests and on the other side by hillsides terraced with rice and millet fields. It’s a fantastic destination for photographers or people who want to just spend time in a typical Nepali village. Home stays can be arranged or you can spend your evenings in the hilltop resort soaking up the village and mountain views. In close proximity is the breathtaking Namobuddha, a famous Buddhist Monastery and Pauntie an ancient Newari Town (Newars are an ethnic group of Nepal), so you can easily spend a few days here and it’s only an hour’s drive plus two hours walk to get there from Kathmandu.

Chisopani – A 16km trek through the Shivapuri National Park takes you to Chisopani, a small village and trekker’s outpost on the valley rim. From here the views rival those from Nagarkot. One can easily spend a few days chilling out here, relaxing, getting to know the villagers, visiting the local cheese factory, explore the Dhaps “wetlands” or just use it as a stopover on treks to Nagarkot, into Langtang and Helumbu or down to Melamchhi. Chisopani is fast become one of the Kathmandu Valleys most popular Hill Stations and its eco and culturally friendly theme make it an ideal destination for those visitors after a taste of what trekking in Nepal is all about.

Pokhara – Not just a starting point or finishing point for trekkers but an unbelievably beautiful and chilled out place to partake in Rekie or Yoga course, or do some meditation in a retreat. Pokhara also has a world class golf course if that’s your cup of tea! It also boasts a stunning 5 star resort, with manicured gardens, tennis court an pool, if you want to do it in style, or just kick back in one of many cozy road and lakeside hotels lining the main strip, packed full of shopping, restaurants and chilled out night spots. Pokhara is the kind of place that one goes to and never wants to leave.

Laptop Stands and Docking Stations, What is the Difference?

If you are a laptop owner, you are probably familiar with the egg frying heat that can accompany extended use of your laptop. This common issue is caused by poor air circulation beneath a laptop. Or perhaps you can feel the ache of your hands after typing on a level keyboard for hours at a time. There is one remarkably simple invention that can solve both the overheating and ergonomic issues many laptops face. It is the laptop stand.

Laptop stands are exactly what they sound like, a small stand that you can set your laptop on. They are normally angled so that the rear of the laptop is higher than the front, much like the effect you get from the legs on a keyboard. This angling is important because the less you have to extend your wrists to reach the keys, the lower the chance of a repetitive strain injury is. But this is more of a by-product of this invention than the driving force behind it.

The impetus behind laptop stands is the overheating issues that many people face when using their laptops. As a friend once said of his new laptop; “You don’t use it on your lap if you want to have kids.” He loved the laptop, but the heat generated by its use was incompatible with the basic function of the computer, something portable enough to place in his lap and use.

Most laptop stands are made to be as portable as the devices they serve. They collapse, fold up, and can stow easily inside a laptop’s carrying case. One product, designed for Mac users, comes with pads that can be used when the stand is on your lap, and can be taken off when using the stand on a desktop.

If you have a dedicated place for using your laptop, you may want to consider upgrading from a laptop stand to a docking station. Where a stand supports a laptop, a docking station is a little bit more elaborate. They feature attachment points for an external monitor, mouse, and keyboard, as well as Ethernet, phone, and USB ports. The docking stations are a step up in utility, but also in price. Where a stand can be found for $ 20 or less, you’ll be hard pressed to find a good docking station for less than $ 90.

Or, if you’re feeling truly handy, a laptop stand can be made from household materials or other equipment retrofitted for use with your laptop. CD racks, towel holders, door stops, binders, and corks are just a few of the materials that have been used to form a do it yourself stand. These stands are generally less stable than a commercially produced one, but if you are just looking for something to use at your desk, they are an inexpensive option.

Drinking Water Stations – How to Avoid Bad Water at the Office

Most public places are required by law nowadays to have drinking water stations readily accessible for people who work or visit there. In attempts to fight potential dehydration, companies place those fountains throughout their building so that people can take a quick sip before they head off somewhere. The problem is that these stations are actually just portals for contaminated drinking water. There are over 2,100 toxins in today’s tap water, and with no filtration on those systems, big companies are basically providing cold toxins for people to take with them during the work day.

Fortunately, there is a little concept called bringing your own bottles of water to work that can help you avoid those nasty drinking water stations. The key to doing this is to get the right containers and the right water to bring along. When it comes to the water itself, you need to make sure that you have a filtration system at home so you don’t just bring contaminated drinking water in a special bottle to work. What would be the sense in that? You can find a good filter to use just on your kitchen sink, or you could go as far as getting one for your entire water supply. Just make sure that whatever you get won’t leave you with contaminated water.

Then you have to pick the bottles to avoid the drinking water stations. Instead of using a classic plastic bottle, you really need to consider glass as your best option. Believe it or not, plastic will actually leach harmful chemicals into your water the longer it sits in the bottle. Glass never has that problem. You’ll never get contaminated water from a glass bottle unless it was contaminated before it got there. Sure these glass bottles may seem heavier than plastic ones and a bit of a hassle to carry around, but they are heavy because they are durable, thus saving you money in bottles that you would normally throw away.

If you bring a bottle of clean drinking water, don’t be tempted to just head to those drinking water stations to fill it back up. If you feel that thirsty, bring multiple bottles to work. Don’t resort to drinking contaminated water just because you think you’re thirsty. Try to plan ahead of time. Bring a whole case of water from home if you’d like. Just be sure that you keep your health in mind at all times and you’ll make the right decisions for your body time and time again.

for Yorkville; see notes…I’m pointing out a few must see sculptures in the area…

This is a very distinguished chunk of downtown Toronto real estate, uptown Rosedale I guess you could call it, though it’s actually north of Summerhill (officially, it’s Yonge and St. Clair, but that sounds so banal). The CHUM city radio building is the major landmark you’ll notice when driving up Yonge Steet.

10 and 20 Avoca Avenue do look quite handsome with the clean lines of their continuous balconies and matching proportions. Overlooking David A Balfour Park, both 19 storey buildings were built in 1971, and according to Emporis at some point they won a Canadian Housing Design Council award of merit. If the Puglyawards were good for one thing, it was introducing me to these two buildings, which are on the top of my list of things to see if I ever go back to visit TO. I’m not sure if architects Seligman and Dick created anything else so wonderful in their careers; I can’t find much more about them aside from this local library.
