WIMAXRURAL – II PROJECT Review Meeting TN

IM

VGR-SSA INDEX for Meeting

• Wireless PANs (Bluetooth – IEEE 802.15)– very low range– wireless connection to printers etc

• Wireless LANs (WiFi – IEEE 802.11)– infrastructure as well as ad-hoc

networks possible– home/office networking

• Multihop Ad hoc Networks– useful when infrastructure not

available, impractical, or expensive– military applications, emergencies

Wireless MANs (WiMAX-802.16)– Similar to cellular networks– traditional base station

infrastructure systems

Wireless networks

 WiMAX is a short name for Worldwide Interoperability of Microwave Access. WiMAX is described in IEEE 802.16e Wireless Metropolitan Area Network (MAN) standard. It is expected that WiMAX compliant systems will provide fixed wireless alternative to conventional DSL and Cable Internet.

Typically, a WiMAX system consists of two parts:

•A WiMAX Base Station: Base station consists of  indoor electronics and a WiMAX tower. Typically, a base station can cover up to 10 km radius (Theoretically, a base station can cover up to 50 kilo meter radius or 30 miles, however practical considerations limit it to about 15 km or 11 miles). Any wireless node within the coverage area would be able to access the Internet.

•A WiMAX receiver - The receiver and antenna could be a stand-alone box or a PCMCIA card that sits in your laptop or computer.  Access to WiMAX base station is similar to accessing a Wireless Access Point in a WiFi network, but the coverage is more.

Several base stations can be connected with one another by use of high-speed backhaul microwave links. This would allow for roaming by a WiMAX subscriber from one base station to another base station area, similar to roaming enabled by Cellular phone companies.

What is WiMAX

BSNL Spectrum & Frequencies

1. Frequency Band Allotted For the BSNL WIMAX Project is 2.5 Ghz.

2. Spectrum For the BSNL Wimax Project is 2635 to 2655 Mhz (20 Mhz Channel).

3.Frequencies used in the Project

* ALPHA Sector : 2637.5 Mhz - Channel Bandwidth : 5 Mhz

* BETA Sector : 2642.5 Mhz - Channel Bandwidth : 5 Mhz

* GAMMA Sector : 2647.5 Mhz - Channel Bandwidth : 5 Mhz

* Spare Frequency : 2652.5 Mhz - Channel Bandwidth : 5 Mhz

WiMAX Speed

• As Per WIMAX Forum WiMax Technology Theoritically Supports the Speed up to 50 to 55Mbps/s with the 20 Mhz Channel Bandwith.

• Practically it will support up to 40 to 45 Mbps/s in the 20 Mhz Channel.

• In BSNL we are using the 5 Mhz Channel bandwidth in all the Three Sectors.

• We will get 14 Mbps/s in all the three Sectors.

• This is also like Wired Broadband, If no of Connections per Sector increases the bandwidth will be shared by the connections.

Mention Realm as “bsnl.in”

Status Tab

The following important parameters are show in the tab1) State2) RSSI 3) CINR4) TxPwr5) BSID

State: There are three types• Scan• Network Entry• Operational “Scan “ indicates the CPE is searching the BTS signal “Network Entry” Indicates the CPE is not getting authentication “Operational” Indicates the CPE got authenticated .

RSSI( Receiver signal strength indicator ) : This parameter indicates the signal strength of the CPE

CINR( carrier interference Noise ratio ) : This parameter indicates the carrier to noise ratio . If the CPE is having the good signal the CINR will be high.

TxPwr ( Transmitted power): This parameter represents the transmited power of the CPE

BSID(Base station MAC id): This parameter displays the MAC id of the base station to which CPE is latched

Types Of Mounting

• On a Pole on Roof Top• Direct on wall /window grill

Two types of installations are visualized

CPE installation on pole

• Recommended pipe :3m to 12 m length• To be installed along the walls of the terrace or building. Make sure that----

(i) That there is a safe access to the pipe, free of any obstacles (ii)That the CPE positioned on the pole cannot be crossed by any body waking on the roof

How to do pole Installation

Secure the pipe to the wall or lift room or any other suitable place with “C” clamps . Make sure that pipe do not rotates in the “C” clamp

C- clamp

Direct on wall /window grill

Directly mount the CPE to the window grail or to the wall

Cabling & Connector Preparation

• The CPE connects the to the POE (Power over Ethernet) box with cad5/cad6 cable with RJ45 connecters on both side

• Support cable length is 100m

• It is important to check the connectivity of the cable before plugging in to the POE and CPE

POE boxCad5/cad6 cable with RJ45

TROUBLE SHOOT

Not able to brose through CPE

• Check the “State“ parameter which is present in the status tab

• If the Scan parameter shown as Scan then the CPE is not getting the BTS signal

• If the Scan parameter shown as Network entry then check for the BSNL user name & password is correct or not
