The first “online” form of telecomHall Community was an e-mail list, using Yahoo! Groups.
The name was Celld-Group and it was a very famous group in Brazil.
Almost every Brazilian telecom professional was a member.
Although the group is “not active” anymore, URL is still working: https://br.groups.yahoo.com/neo/groups/Celld-group
Celld-Group needed a website.
So, we’ve partnered with a great website managed by Helio Rosa: the Wireless BR Community.
During years, all good information from Celld-Group was transcripted by Helio Rosa to the WirelessBr site.
Although “not part” of telecomHall anymore, Wireless BR Page is also still working: http://www.wirelessbrasil.org/
