WLAN is becoming increasingly popular in enterprise applications. Like all new technologies, the demand for performance improvement has become increasingly urgent. At present, most WLAN applications use a GHz frequency band, and the penetration and diffraction capabilities are still flawed. However, construction and large-scale operating equipment in the enterprise environment can easily cause blind spots of WLAN coverage. To extend the

Now we have more and more mobile phones, tablets, laptops and other wireless devices, how to get a better WiFi experience has become our focus. However, in the face of large or complex house structure of the room, wireless signal often become unstable, WiFi coverage effect has become very unsatisfactory, "wireless corner" is more people do not want to see the situation. So, when we step into the computer city and start thinking about provisioning a ne

In a sentence:code coverage tells your what you definitely Haven ' tTested, not what have. Part of building a valuable unit test suite is finding the most important, high-risk code and asking hard of it. You are want to make sure the tough stuff works as a priority. Coverage figures have no notion of the ' importance ' of code, nor the quality of tests. In my experience, many of the most important tests yo

Before doing statistical code test coverage, generally with cobertura. Previously statistical test coverage, generally only unit test, or close the eyes of the unit test and integration test together.However, we have gone through the age of superstition UT: UT does not support large-scale refactoring, and if the refactoring of classes and methods is split, UT loses the function of ensuring that ref

Early in the morning, a young programmer asked the master: "I'm going to write some unit test cases. How much code coverage should be achieved ?" The master replied: "Do not consider code coverage. Just write some good test cases ." Young programmers are very happy to bow and leave. Not long afterwards, the second programmer asked the master the same question. The master pointed to the boiling water i

What is coverage? The coverage data model originated from ArcInfo, the first commercial GIS software launched by ESRI in 1981. Also known as the georelational data model, it is a model of the second generation of spatial data models. Coverage spatial data Topological Relationship Model Coverage uses "arc segments" as

Although 4G is commercially available for half a year, the base station has poor network coverage and weak mobile phone signals, but there are still situations where the base station cannot be online or make phone calls. However, if the carrier uses a superconducting link system, mobile phone users do not have to worry about this. Recently, reporters from a third-party detection agencies to a test results report that the use of superconducting lte rf

Extending network coverage using wireless access points as repeaters because it has been encountered many times and is very representative (and will save a lot of money), so I decided to release the solution here. The situation is this: if you need to use a wireless network, but the scope is too large, a wireless router can not achieve full coverage of the situation. And, because the price is too expensive,

In reality, cable broadband has encountered bottlenecks in many places, such as the decline in the delivery of various ISPs and the extraction of landlords, resulting in lower profits. At this time, WiFi coverage is a brand new drive. In the case of Wi-Fi coverage, you can search for Wi-Fi signals to know your network. You do not need to post advertisements on the street and reduce the maintenance intensit
