Making your home a Wi-Fi Zone – Part 2
In our previous article posted on 2nd January, we introduced the concept of Wi-Fi in your home. Today we are presenting the two options in detail which you can adopt in making your home a wireless hotspot.
If you are about to take a new internet connection from your ISP (internet service provider), then option 1 is just the one for you. Most ISP in India like Airtel, BSNL offer the consumers with the option of either hiring or purchasing a wireless modem/router. This is a single device which not only makes high speed internet possible but also gives out the required wireless signal which can be accessed by laptops and desktops having wireless capabilities. The rough block diagram for the same is given below.
For consumers who are already a broadband customer, you could consider option 2 if you haven’t purchased your modem in the first place. You have an option of getting your modem changed and renting a wireless modem instead. Please note that the monthly rental rates for a wireless modem is typically higher than that of the regular modem.
However, if you already own the modem, then you can purchase a wireless router from the electronic stores and connect it to your modem creating a wireless network in your home. The block diagram for the same is shown below. Note: In addition to creating a wireless network in your home, the router also tends to add upto 4 LAN ports. This means you could connect more than one PC to your network and all of them can share the same internet connection. This is an added advantage in purchasing an external wireless router.
In option 1, the wireless modem allows you to connect only one wired device. The number of wireless devices which can connect to the router is not really defined. Here again the wired and wireless devices can use the same internet connection easily.
Common brand names in the wireless router space are Netgear and Linksys. OEM versions in option 1 can be supplied from companies such as Beetel, Huawei, UT Starcom etc.
The wireless standards that exist today are:
The first one gives a speed of upto 54 Mbps with limited range. 802.11b improves the range but the operational speed is 11 Mbps instead. The last one encompasses both “a”and “b” standards giving consumers the best of both worlds.
Some more details can be found here. The most recent development in the wireless space is the 802.11n version. This offers almost twice the speed with improved coverage. Devices complying to this are still expensive. Just to let you know that the broadband speeds in India are the bottleneck today and not the speed at which your router operates !
