Transferring wi-fi suppliers to the 5.6GHz band because of the upcoming 5G spectrum public sale on the three.6GHz band might impression climate satellites throughout a lot of the nation, the Bureau of Meteorology (BoM) has stated.

“The Bureau of Meteorology is worried the reallocation of Wi-fi Web Service Suppliers (WISPs) to the 5.6GHz band might intervene with present radars and constrain future growth and reconfiguration of its radar community,” the BoM stated in response to Senate Estimates Questions on Discover.

The 5.6GHz spectrum is at the moment used for BOM’s 47 C-Band climate radars.

Doubtlessly affected C-Band climate radar areas proven on BOM’s map embrace Sydney (Kurnell), Melbourne Airport, Melbourne (Laverton), Adelaide (Sellicks Hill), Perth Airport, Perth (Serpentine), Hobart Airport, Hobart (Mt Koonya), Cairns, Townsville (Hervey Vary), Wagga Wagga, Kalgoorlie, Mildura, Geraldton, NW Tasmania (West Takone), Yarrawonga, Broadmeadows, Mt Gambier, Moree, Woomera, Ceduna, Bairnsdale, Warrego, Longreach, Mackay, Bowen, Weipa, Albany, Esperance, Newdegate, South Doodlakine, and Watheroo.

Unaffected C-band climate radars are restricted to Darwin (Berrimah), Darwin Airport, Alice Springs, Broome, Norfolk Island, Katherine (Tindal), Port Hedland, Mornington Island, Willis Island, Warruwi, Wyndham, Halls Creek, Dampier, Learmonth, Carnarvon, and Giles.

In keeping with the BoM, the Australian Communications and Media Authority (ACMA) had consulted BOM immediately, through e mail, and through its public session course of on the spectrum reallocation earlier than reaching the choice to shift WISPs and satellite tv for pc suppliers over to make approach for cellular broadband.

The ACMA had launched its five-year plan for spectrum allocation in October alongside “a spread of mitigation measures” for incumbent customers within the three.6GHz band, together with “a dedication to creating preparations for site-based wi-fi broadband providers within the 5.6GHz” band, help for ongoing entry to spectrum, and figuring out earth station safety zones on Australia’s east coast.

This adopted arguments from incumbent wireless ISPs and satellite groups that the spectrum shouldn’t be taken away from them and given to cellular telcos.

In March, Communications Minister Mitch Fifield then introduced that present services in the 3.6GHz band will have up to seven years to vacate in regional areas, and solely two years in most capital cities

“I’ve fastidiously thought of the implications for regional Australians in making this determination, and the declaration supplies protections for incumbent customers within the band whereas guaranteeing Australia is well-positioned to make the most of 5G know-how in years to return,” Fifield stated on the time.

“The ACMA’s advice supplies for an unprecedented seven-year reallocation interval in regional Australia. This can permit incumbents, similar to regional fixed-wireless broadband operators, to proceed to ship providers till the center of subsequent decade — and this might proceed past the reallocation interval if agreed with a brand new spectrum licence holder.”

This adopted the discharge of the federal government’s 5G policy paper, which stated the ACMA would carry the three.6GHz spectrum band for 5G use to public sale in 2018.
