Why Your Home Wi-Fi Is Lousy

Wi-Fi at home should look at the following consideration :-Reply
(1) Internet gateway - what is the bandwidth subscribe to? 10 Mbps, 100 Mbps or 1 Gbps?
If wireless LAN is 54 Mbps from IEEE802.1g - then the bottleneck for video downloading from Internet will be 10 Mbps - if subscribers subscribe to 10 Mbps Internet with its ISP.
(2) Is 1 Wireless LAN gateway cum access point (AP) sufificent to support the wireless access in every part of the house? Sometimes, wireless may not able to get through a wall into a bedroom - due to poor signal strength. When this happen, a hi-power long range anternnae for the AP will be required o boost the wireless signal strength. But this mean human brain will subject to higher power antennae and radio frequency bombardment.
(3) This article even proposed "wireless mesh backbone" - by putting more APs eg. 1 in the hall, 1 each in the bedroom to boost the wireless signal strength. Then the installation will require high-tech system integrator class of technical expertise to implement the "wireless mesh backbone" - eg. using IEEE802.1ac (1.2Gbps) configure as wireless backbone and IEEE802.n as end-device wireless adapter access (as iEEE802.1ac - does not have an end-device wireless adapter access yet). When this happen, the backbone and the end-access will have to run at different radio frequency to prevent wireless interference - where for eg. backbone running at 2.4Ghz and the end-access at 5 Ghz.
