Hardware Device of Wimax Technology

WiMax products:

WiMAX technology is new therefore its products are not as well known as products of technology Wifi known to every one. This does not mean WiMAX is not popular enough that no products are yet launched. There are several products for WiMAX subscribers which are available in market with limitations because not many subscribers demands for it. All the products which are used for WiMax deployment are installed with WiMAX chip and they are mostly certified by WiMAX forum, WiMAX forum is one of the pioneers in promoting and setting standards in WiMAX technology and its deployment.

WiMax products can be categorized into two parts, Indoor products and Out door products.

Indoor WiMax products:

WiMAX indoor products which are basically used at the subscribers end.

• WiMax indoor subscriber unit(SUI):
  This device is indoor wireless subscriber access product which is designed on protocol IEEE 802.61-2004 standards. This device compatible to MPM equipment PMP is point Multipoint. Device has multiple Ethernet ports interface including (VoIP). SUI have LED installed on its front side which shows the strength of the signals. This is third generation device (3G). SUI uses technology called Orthogonal Frequency Division Multiplexing (OFDM) and non-line-of-sight (NLOS) technology enables handling rural and urban obstacles like trees, building even mountains to keep the connection to the link

 

• WiMAX External antenna:
  This external antenna is used to improve the signal strengths of WiMax subscribers from base station. WiMax external antennas are mostly required when subscriber is located in middle of populated or dense area; it can also be used where high mountains, and tree creates obstacles within base station and subscriber location. Antenna is connected with wire to indoor subscriber unit SUI to strengthened the signals

 

WiMAX Outdoor products:

• Outdoor Subscriber Unit (SU-O):
   This outdoor subscriber unit (SU-O) works exactly like SUI. The only different this product is its outdoor usability. It forms connection to WiMax base station to provide broadband access to WiMax subscriber. Its way of functionality is no different than SUI.

 

• WiMAX Certified Base Station:
   The world’s first WiMAX forum certified base station is Redlines’ RedMAX AN-100. This device works and base station for WiMax, it is easy to install and very cost effective for deployment. Its low latency makes sure that it provide delivery of good quality and sensitive services, including voice traffic, voice over ip (VoIP), video and data traffic.An-100 designed architecture assures over-the-air facility with help of software. It also has dynamic ability of on-the-fly services.

 

AN-100 base station can be used in cluster of 60 degree sectors; this supports many unique data flows and many subscribers simultaneously per sector. It synchronizes its time with GPS system for spectrums and available channels. Its hardware is easily upgradable in field by software downloads.

Future Products:

There are other products which are important in normal use for general public. These are Wimax cards for laptops and desktop computers with WiMax chip install in them. Pdas and other handsets with Wimax ability. This is the future deployement of WiMax products. They are very rare in market or under testing process. The WiMax chip is not feasible to be install in such products as it has high cost. We will have to see how soon WiMax technology deployment takes over older technologies like WiFi and how soon these products comes with WiMax chip built in with in cost of range for normal user.
