无线上网技术(WiFi)，在中文里又称作“行动热点”，是一个创建于IEEE 802.11标准的无线局域网技术。
2.4GHz是一种全世界公开使用的无线频段，5GHz也是一种全世界公开使用的无线频段。这两种频段适用于短距离无线传输技术，在家用及商用领域中具有广泛的应用。然而，5GHz频段中数据的传输速率高于2.4GHz频段中数据的传输速率。通常，当工作站(station，STA)通过接入热点(access point，AP)接入无线网络时，AP可以设置STA接入2.4GHz频段，也可以设置STA接入5GHz频段。当STA接入一个通信频段之后，可以通过AP与其他设备进行网络通信。
现有的AP设置STA接入无线网络时，一般会默认将STA接入至2.4GHz频段。STA会在2.4GHz频段通过AP与其他设备进行网络通信。这样，STA接入无线网络后数据传输速度慢，使用STA的用户上网体验差。

具体实施方式
下面结合附图，对本申请的实施例进行描述，显然，所描述的实施例仅仅是本申请一部 分的实施例，而不是全部的实施例。本领域普通技术人员可知，随着技术的发展和新场景的出现，本申请实施例提供的技术方案对于类似的技术问题，同样适用。
本申请的说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便这里描述的实施例能够以除了在这里图示或描述的内容以外的顺序实施。此外，术语“包括”和“具有”以及他们的任何变形，意图在于覆盖不排他的包含，例如，包含了一系列步骤或单元的过程、方法、系统、产品或设备不必限于清楚地列出的那些步骤或单元，而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。
本申请实施例中，2.4GHz是一种全世界公开使用的无线频段，5GHz也是一种全世界公开使用的无线频段。这两种频段适用于短距离无线传输技术，在家用及商用领域中具有广泛的应用。然而，5GHz频段中数据的传输速率高于2.4GHz频段中数据的传输速率，5GHz频段中数据传输的抗干扰能力也会优于2.4GHz中数据传输的抗干扰能力。通常，当工作站(station，STA)通过接入热点(access point，AP)接入无线网络时，AP可以设置STA接入2.4GHz频段，也可以设置STA接入5GHz频段。当STA接入一个通信频段之后，可以通过AP与其他设备进行网络通信。
现实生活中，5GHz频段中传输信号的频率较高，5GHz频段中传输信号的波长相对于2.4GHz频段中传输信号的波长较短。因此5GHz频段中传输信号的穿透性比2.4GHz频段中传输信号的穿透性差，且5GHz频段中传输信号的覆盖范围比2.4GHz频段中传输信号的覆盖范围小。现有的AP设置STA接入无线网络时，一般会默认将STA接入至2.4GHz频段。STA会在2.4GHz频段通过AP与其他设备进行网络通信。这样，STA接入无线网络后数据传输速度慢，使用STA的用户上网体验差。
针对现有的无线网络的接入技术存在的上述问题，本申请实施例提供了一种无线网络的接入方法及相关设备，在某些场景中能够提升STA的数据传输速率，提升用户上网体验。
图1是本申请实施例提供的无线网络的接入系统的应用场景示意图。
请参阅图1，本申请实施例中，工作站STA以及接入点AP组成无线网络的接入系统。
本申请实施例提供的无线网络的接入系统包括：AP101，STA102,STA103以及STA104。
其中，STA102与AP进行数据交互，STA103与AP进行数据交互，STA104与AP进行数据交互。
本申请实施例中，仅以一个AP和三个STA为例进行说明。实际应用中，可选的，本申请实施例的应用场景中可以包括多个AP，以及比图1实施例中所提供的更多或者更少的STA。
STA在无线网络的接入系统中一般为客户端，STA可以是移动的，也可以是固定的，是无线局域网的最基本组成单元。可选的，STA可以是装有无线网卡的计算机，STA也可以是有WiFi模块的智能手机，STA还可以是其他网络相关设备，具体此处不做限定。
AP是无线局域网的一种典型应用。AP是无线网和有线网之间沟通的桥梁，是组建无线局域网的核心设备。AP主要是提供无线工作站和有线局域网之间的互相访问，这样，在AP信号覆盖范围内的STA可以通过AP进行相互通信，没有AP基本上就无法组建真正意义上可访问网络的无线局域网。可选的，AP可以是无线路由器，AP可以是无线网关，AP还可以是其他网络相关设备，具体此处不做限定。
本申请实施例中，当使用STA的用户有接入无线网络的需求时，则用户使用STA在第一频段向AP发送探测请求。第二频段中数据的传输速率高于第一频段中数据的传输速率。AP 根据该探测请求判断用户是否具有接入第二频段的能力。如果AP确定STA具有接入第二频段的能力之后，AP会在第二频段向STA发送探测响应。这样，STA就可以根据该探测响应接入第二频段。进而，STA接入无线网络后数据的传输速度快，使用STA的用户上网体验好。
