What is the channel bandwidth used by our wireless equipments?
A. Channel bandwidth is the amount of spectrum space a particular wireless product occupies in a band. WPC has allocated multiple spots of 6 MHz in 2.7 to 2.9 GHz band to HCL Infinet. The equipments installed, uses upto 5 MHz of channel frequency. The extra one MHz is used as the guard band to prevent interference from other service provider’s links operating in the consecutive frequency spots. The requirement of 5 MHz channel size, enables HCL to commission interference free links in free band of 2.4 or 5.8 GHz band. This is done by choosing the 5 MHz spot with least interference from the 80 Mhz spectrum available in 2.4 GHz or 50 Mhz spectrum available in 5.8 Ghz band.
