11n vs. 150M and 300M internal battle cost the king

If the wireless network in the world is divided into two halves, half of which must be as bright as the example of clashes between 3G, while the other half is as quiet as the water gently WiFi. Compared to high-profile 3G, WiFi in the world is always so calm, so the alarm, but that calm does not mean that WiFi in silence, it is ready, waiting for overnight success.

Then in 2009 what the world highlights WiFi? The answer is the 150M, as the IEEE 802.11n standard rate under a standard, it appears not only broke the WiFi world peace, to break the monopoly of 300M. 150M capabilities then what? It is not a lot of people in the "non-mainstream" speed standards? We will duel it 300M to tell you the answer, to tell you who is the king of cost-11n world.

Rectification of names for the 150M it is definitely not "non-mainstream"

150M really is a "non-mainstream" it? Is not true, although many users of traditional values, 802.11n represents the 300M, 300M also represents the 11n, but this is not true, according to IEEE official description, 11n standard was actually For four speed grades, that is, 150M, 300M, 450M and 600M, 150M so that is definitely not "non-mainstream."

150M has been the rectification of names, it's the actual performance of what? It how big the gap 300M? 150M and 300M Who is more worth buying? The answer will duel in the following test revealed for you 11.

Sets or returns the regular expression search mode.

object.Pattern [= searchstring]

Parameter
object

Required. Is always a RegExp object variable.

searchstring

Available options. By regular string expression search. It may contain some form to set the regular expression in a variety of characters.

Set up

In writing the regular expression pattern used special characters and sequences. The following table describes the characters and sequences can be used, and gives examples.

Character Description
Will be the next character is marked as a special character or literal. For example, with the character n n match. n with newline matches. Sequence \ and match, (and (match.
^ Matches the beginning of the input.
$ Matches the end.
* Matches the preceding character zero or a few times. For example, zo * matches z, zoo.
+ Matches one or more times the previous character. For example, zo + can match the zoo, but does not match the z.
? Match the previous character zero or one. For example, a? Ve? Can never match the ve.
. Matches any character other than newline.
(Pattern) and pattern matching and remember the match. Matched substring can be as a result of the Matches collection using the Item [0 ]...[ n] to obtain. To match parentheses characters (and), use (or).
x | y matches x or y. For example, z | food can match the z or food. (Z | f) oo match the zoo or the food.
(N) n non-negative integers. Match exactly n times. For example, o (2) can not be matched with Bob in the o, but can foooood o in the first two matches.
(N,) n non-negative integers. Match at least n times. For example, o (2,) does not match Bob's o, but the match foooood all of the o. o (1,) is equivalent to o +. o (0,) is equivalent to o *.
(N, m) m and n non-negative integers. Match at least n times, at most m times. For example, o (1,3) matches fooooood in the first three o. o (0,1) is equivalent to o?.
[Xyz] A character set. And one of the characters in parentheses matching. For example, [abc] matches the plain in a.
[^ Xyz] A negative character set. This does not match any character in brackets. For example, [^ abc] can match the plain in the p.
[A-z] that a range of characters. Within the specified range matches any character. For example, [az] match between a and z any lowercase characters.
[^ M-z] in the negative range characters. And not in the specified range of characters matched. For example, [mz] m to z and not on any of the characters between the matches.
b and the word boundary matching, that is, the location between the words and spaces. For example, erb er and never in the match, but does not match the verb in the er.
B and non-word boundary matching. ea * rB and never early match in the ear.
d with a number of character match. Is equivalent to [0-9].
D matches with non-numeric characters. Is equivalent to [^ 0-9].
f and page breaks match.
match n with newline characters.
r and carriage return characters match.
s matches any white characters, including spaces, tabs, page breaks and so on. Is equivalent to [fnrtv].
S and any non-blank character match. Is equivalent to [^ fnrtv].
t match with the tab.
match v with vertical tabs.
w matches any word character including underscore. Is equivalent to [A-Za-z0-9_].
W matches any non-word character. Is equivalent to [^ A-Za-z0-9_].
num num match, of which num is a positive integer. Reference back to remembered matches. For example, (.) 1 matches two consecutive identical characters.
n match n, where n is an octal escape value. Octal escape values must be 1, 2 or 3 digits long. For example, 11 and 011 are matched with a tab. 0011 is equivalent to 001 and 1. Octal escape values must not exceed 256. Otherwise, only the first two characters are treated as part of an expression. Allows the use of regular expressions ASCII code.
xn match n, where n is a hexadecimal escape value. Hexadecimal escape values must be exactly two digits long. For example, x41 Match A. x041 is equivalent to the x04 and 1. Allows the use of regular expressions ASCII code.

Explain

The following code illustrates the use of Pattern attributes:

Function RegExpTest (patrn, strng) Dim regEx, Match, Matches''to establish variable. Set regEx = New RegExp''to establish a general expression. regEx.Pattern = patrn''set the pattern. regEx.IgnoreCase = True''settings are case-sensitive. regEx.Global = True''set the global availability. set Matches = regEx.Execute (string)''Repeat match set RegExpTest = regEx.Execute (strng)''perform a search. for each match in matches''Repeat match set RetStr = RetStr & Match found at position RetStr = RetStr & Match.FirstIndex &. Match Value is''RetStr = RetStr & Match.Value &''.& vbCRLF NextRegExpTest = RetStrEnd FunctionMsgBox (RegExpTest (is., IS1 is2 IS3 is4))
