What is WiMAX and it IEEE? - ANSWER✔✔--Worldwide Interoperability for Microwave Access
-IEEE 802.16 WWAN
In cellular broadband there are two types of cellular networks, what are they? - ANSWER✔✔-
Global System for Mobile (GSM) and Code Division Multiple Access (CDMA).

What are Controller-based APs? - ANSWER✔✔--These devices require no initial configuration and
are often called lightweight APs (LAPs).
-Also called thin APs
-Centralized management, configuration, encryption, updates and policy settings through a
centralized controller

What is infrastructure mode in WLAN? - ANSWER✔✔-A wireless router or AP connects wireless
clients to a wired distribution system.
What is API and what does the acronym stand for as well? - ANSWER✔✔-Application
Programming Interface (API)
An API is software that allows other applications to access its data or services. It is a set of rules
describing how one application can interact with another, and the instructions to allow the
interaction to occur.
Data formats shared between smart devices often use an Application Programming Interface (API
There are four types of web service APIs - ANSWER✔✔-Simple Object Access Protocol (SOAP)
Representational State Transfer (REST)
