随着无线网络标准和技术以及成熟设备的快速发展，越来越多的企业已经开始选择无线设备建立企业内网，这样除了传统有线LAN网络外无线内网也越来越得到企业青睐。不过由于无线技术传输标准的差异，在实际数据的无线传输过程中或多或少因为标准的不统一而影响传输效率。今天笔者就根据自己经验为各位IT168的读者介绍两个小技巧，通过这些技巧我们可以让企业的无线内网事半功倍。
技巧一：限制无线传输标准让“大家”向高标准看齐
众所周知我们日常使用的无线标准都是由IEEE协会制定的，从早期的802.11b到后来的802.11g，再到目前如火如荼的802.11n。不同标准在无线传输上的效率是不一样的，速度方面的差异也非常大。不过由于这些标准之间都是相互兼容的，这也是为什么在由多个不同无线标准组成的网络内大家还是可以正常传输的原因。不过正是这种相互兼容的特点让设备之间的传输速度受到了影响，各个无线设备都将以“向低标准看齐”的策略来完成无线通讯，从而拖慢了企业内网数据的传输效率。
这种标准之间互相兼容且“向低标准看齐”的特点很容易造成“一马勺坏一锅”的恶劣后果，也就是说企业内部可能有很多802.11g标准的设备，也有部分802.11n标准设备，那么在实际传输过程中802.11n设备会相应的减低速度到54M和802.11g设备通讯。然而当企业网络内突然出现一个更低速度的设备――802.11b产品，那么由于他连接到了网络中，原本按照54M速度传输的所有设备都要降低速度到11M传输，这样就严重的影响了企业内网传输效率。
这种降低速度情况与现象并不仅仅发生在802.11b产品与802.11g,802.11n设备的通讯上，由于无线网络的核心是无线路由器，网络中的各个设备都会同他先进行通讯，所以802.11b产品将直接影响无线路由器的速度，让无线路由器降低为802.11b标准进行传输。当无线路由器降低到802.11b标准后网络中的其他设备也无可奈何的降低速度到802.11b标准传输了。这样的结果就造成了原本工作在54M速度下的各个设备都不得不因为网络内出现一台802.11b设备都全部降低速度到11M了。

MySQL BLOB: how to optimize BLOBs requestsMay 13, 2025 am 12:03 AMOptimizing MySQLBLOB requests can be done through the following strategies: 1. Reduce the frequency of BLOB query, use independent requests or delay loading; 2. Select the appropriate BLOB type (such as TINYBLOB); 3. Separate the BLOB data into separate tables; 4. Compress the BLOB data at the application layer; 5. Index the BLOB metadata. These methods can effectively improve performance by combining monitoring, caching and data sharding in actual applications.
Adding Users to MySQL: The Complete TutorialMay 12, 2025 am 12:14 AMMastering the method of adding MySQL users is crucial for database administrators and developers because it ensures the security and access control of the database. 1) Create a new user using the CREATEUSER command, 2) Assign permissions through the GRANT command, 3) Use FLUSHPRIVILEGES to ensure permissions take effect, 4) Regularly audit and clean user accounts to maintain performance and security.

MySQL: String Data Types and Indexing: Best PracticesMay 12, 2025 am 12:11 AMBest practices for handling string data types and indexes in MySQL include: 1) Selecting the appropriate string type, such as CHAR for fixed length, VARCHAR for variable length, and TEXT for large text; 2) Be cautious in indexing, avoid over-indexing, and create indexes for common queries; 3) Use prefix indexes and full-text indexes to optimize long string searches; 4) Regularly monitor and optimize indexes to keep indexes small and efficient. Through these methods, we can balance read and write performance and improve database efficiency.
