Core Technology
At the core of WiMAX is the WiMAX radio. A radio contains both a transmitter (sends) and a receiver (receives). It generates electrical oscillations at a frequency known as the carrier frequency (in WiMAX that is usually between 2 and 11 GHz). A radio might be thought of as a networking device similar to a router or a bridge in that it is managed by software and is composed of circuit boards containing very complex chip sets.
WiMAX architecture, very simply put, is built upon two components: radios and antennas. Most WiMAX products offer a base station radio separate from the antenna.
The chief advantage of this is that the radio is protected from extremes of heat cold and humidity, all of which detract from the radio’s performance and durability. In addition, having the antenna outdoors optimizes the link budget (performance of the wireless connection) between transmitter and receiver especially in line of sight scenarios.
WiMAX antennas, just like the antennas for car radio, cell phone, FM radio, or TV, are designed to optimize performance for a given application. The three main types of antennas used in WiMAX deployments are an omni directional, sector, and panel antenna,where each has a specific function.
Given that WiMAX reception is not impeded by walls of concrete or brick, RF blocking glass or steel in the building's walls, WeWi Telecommunications will mostly be focused using Indoor CPE. As Outdoor subscriber stations offer only slight improvement over indoor stations but cost more due to measures necessary to make them weather resistant.
The most significant advantage of the indoor over outdoor CPE, is that it is installed by the subscriber. This frees WeWi Telecommunications from the expense of "truck roll" or installation. In addition, it can be sold online or in our planned retail facility thus sparing the service provider a trip to the customer site. Indoor CPE also allows a certain instant gratification for the subscriber in that there is no wait time for installation by the service provider.
An instant delivery of service is very appealing to the business subscriber in the event of a network outage by the incumbent service provider.
