What is Wimax repeater
Post by Jawad Ahmad Riaz
Introduction: Wimax repeater is a booster that is basically used to amplify the weak Wimax signals. This device amplify the signals and then retransmit these signals so that the coverage of the base station can be expanded up to 20km to 6miles, depending on the device capability. This device is also used when you are in the coverage area but because of obstacles Wimax signals get weak. This repeater is consisted of two transceivers; these transceivers are basically designed to omit the use of cable with the antennas of both ends.
Wimax repeater use ALC (Automatic Level Control) circuit which provides stable output signals regardless of changing natural conditions. For the connection of Wimax repeater the only thing that is required from outside is electric power.
Benefits of wimax repeater: The benefit of using this device is that user can access fixed broadband services beyond the Wimax coverage area. Wimax repeater makes sure that high speed and fixed connection rate is provided. The output and input of signals are upgraded with the help of this device. Remotely Wimax repeater device can be controlled via SNMP. This repeater provides better in-building coverage and programmable frequencies. With the use of this repeater, cost effectively base station footprints can be extended for additional users. Wimax repeaters give an edge for the battery issues, because the battery can help you to run this device for next 3 to 4 days without giving any external power supply to it. These repeaters ensure that frequency of the system is offset and with that they improve the working stability. One to one system or one to many systems can work easily in the broadband network if Wimax repeater is used for connection to internet.
Latest modifications: Wimax repeaters are not only designed for desktop computers or laptops. In the next step of evolution of Wimax repeaters, this service is also covering the wireless broadband on mobile phones. In the recent times Wimax will be able to provide high speed internet service to mobile users. This repeater will make it sure that users can access all the services and information on their mobile devices faster then the Wi-Fi system. The new modified Wimax repeaters would be based on IEEE 802.16e standard aimed at providing the benefits of both Wimax’s fixed and mobile capabilities.
One new thing that is introduced in the world of Wimax repeaters is a repeater with 5GHz bands. These are new non-regenerative repeaters which allow transparent coverage extension in adverse scenarios and are fully interoperable with IEEE 802.16-2009 compliant Base Stations. These repeaters not only amplify the signals but with that these repeaters provide space and frequency diversification options replicating signals of base station at any other channel. This new type of repeater gives us cost effective benefit, which is that with increased frequency there is no need for expensive high-power Base Stations.
Models and Types: Most easily available models of Wimax repeaters range form (10dbm, 13dBm, 1w, 2w, 5w), with frequencies 2.4GHz~2.7GHz , 3.4GHz~3.7GHz. Communication systems that these repeaters use are Dual Band, CDMA, WCDMA, GSM,DCS, PCS and TETRA. The maximum out-power of these repeaters vary between 10dBm,15dBm, 20dBm, 23dBm, 27dBm,1W,5W,10W,20W,40W. All these Wimax repeaters provide high speed internet to users on mobile devices. This speed can be ten times faster than HSCPA or traditional connections. With the help of this repeater the cost of signal coverage can se reduced easy as we add more BTS sites for the extension of coverage.
Types in which Wimax repeaters are offer to customers are Fiber Optic Repeater, Microwave Repeater, Dual Band Repeater, Band Selective Repeater, Frequency Shift Repeater and Pico Repeater.
With the passage of time new and modified types of these repeaters are coming in the markets. All of those are giving us a new experience of using repeaters, because they are increasing the range in which we can use our device.
