DD-WRT : Linux based Alternative OpenSource Firmware

1.   After we have heard and seen over last few years the rise of Open Source and their imminent threat to Mac and Windows!!!!,now I read about  , a Linux based alternative Open Source firmware suitable for a great variety of WLAN routers and embedded systems.

2.    This open-source firmware was developed for specific router models and is used as a replacement for the factory default firmware. This modification lifts restrictions built-in to the default firmware, providing advanced capabilities to make Internet and Home Network more controllable and versatile.Manufacturers develop routers for non-technical users in mind, making them simple and easy to use, while limiting their effectiveness as a web-access gateway. DD-WRT transforms a personal-class router with limited functionality into a powerful, multi-use, business-class router. With DD-WRT, a router's enterprise potential can be unlocked at a home user's price.

3.    The advantages offered are bought out below :

    - Stability of running a linux-based, non-proprietary firmware.
    - VPN (Virtual Private Network) passthrough capabilities.
    - Software support for the SD-Card hardware modification.
    - Advanced QoS (Quality of Service) controls for bandwidth allocation.
    - NAT (Network Address Translation) support.
    - Cycle router from the Administration settings.
    - Built-in DNS caching
    - Configure the router as a Wi-Fi hotspot using the integrated Chillispot          
    - Radius Authentication for additional wireless security.
    - VLAN (Virtual Local Area Network) Support.
    - Create unique SSIDs (service set identifiers) when using multiple routers.

4.   But it is not a win win situation always,while flashing a router with DD-WRT is highly beneficial , the risks that are involved can sometimes outweigh the benefits . Flashing a router with DD-WRT can be risky and when done improperly, it may "brick" the router. For devices mainly used for private purposes, DD-WRT is freely available. Platforms used for commercial purposes require a paid license. Compared to the freely available version, the professional version also allows for configuration of the WLAN parameters, thus opening up the opportunity of creating e.g. reliable and powerful network infrastructures. Special demands can be fulfilled by specifically tailored versions of DD-WRT.

4G drives to Indore in Cars and Motors via BSNL

1.   Indore is keeping its surfing grounds ready to welcome the 4G speed @ courtesy BSNL.Likely to be launched in some time May 2013......this will also be the first time some thing known as WiFi based "Internet on wheels" will be launched...but that is scheduled slightly later.

2.   Key features about the same :

 - 8 Mbps speed

-  Wi-Fi-based internet facility to motorists on move

-  Rough payment plans :
   
-   "BSNL's internet-activated car kit would be available in three ranges of one time payment plans that include : 
      - Rs 6500, 
      - Rs 27,500 
      - Rs 29,500

-  This will come along with a standard dial-up plan of Rs 250 per month.

3.  Here you go Indore'ites....all the best....but at the same time what props up is how will the gadgets handle this 4G speed....will the already held 3G mobiles and Tabs be able to take on the new G or are we awaiting new advertisements to lure us buying 4G devices!!!!

WiMAX - THE POWER

For so long ....may be about two weeks I have not been able to upload any posts on this blog...courtesy an opportunity to slightly dig deep into WiMAX...and I am really happy to have finally got deeper into this.I got to know about various Wireless Technologies and terms viz OFDM, MMDS, LMDS, Blue tooth,WiFi,EVDO, the 'G' family, HSPA, 802.16M, 802.20, Cable modem, broad band over power line, LTE, FTTH, spectrum bands, base stations, CPEs, NOCs, EDGE,Gateways,Back haul links,Security aspects of WiMAX.....a lot of learning...gr8888...will share brief on all these aspects in days to come....
