This guidance provides access patterns for automatic joining or roaming of all government owned and managed devices with a standard service set identifier SSIDcontrolled guest access to government workplace wifi. It describes how to retrofit these patterns to existing wifi and public key infrastructures PKI. Follow this wifi technical specification. Access. Devices should access government wifi networks by either one of automatic joining of trusted networks using certificatesuser initiated sign in with minimal staff management overhead. Service providers must use cross government authentication solutions to allow clients to roamminimise the intervention required by users trying to gain wifi accessstandardise the process by which access is provided to a specific set of SSIDsprovide an acceptable use policy AUP for users, where they have not already agreed to one as part of the sign in processensure that logging and auditing of wifi network use is in line with the current legal requirements and the organisations security policybe prepared to answer official requests for informationlimit the SSIDs broadcast, documenting exceptions. Network separation. Network separation is required to share government wifi resources. You must put mechanisms in place to isolate wireless wifi traffic by SSIDcertificate authority CA, identified by a device certificate. Service providers must provide a mechanism for separating wifi network traffic belonging to users of particular classes such as guests and different organisations, using one of the following methods connecting to separate virtual local area networks VLANs at the wifi access point AP where they are standalone or cloud managedseparating traffic at a central point like a wireless controller traffic should be securely tunnelled from the AP to the tunnel termination point where it can be more easily separated from different VLANs or interfaces, or tunnelled to a different controlleremploy separate IP addressing, routing and access controls for each wifi networkprioritise and manage the competing bandwidth requirements of the different classes of userisolate wifi clients from one another to prevent a compromised device attacking others on the network where a wireless client provides services, you should move it to a different VLANService providers should deploy guest wifi on a workplace network using the separation methods aboveconsider complementing wifi with remote access solutions, like client VPNs, to provide end security for devices connecting back to home organisation networks or platformsconsider using encrypted tunnels between access points and controllersconsider the benefit of providing home organisation users access to corporate resources and local breakout to cloud servicesconsider implementing location based restrictions like geofencing tools to restrict access to back end systems to specific locations. Bandwidth and access. Users expect wifi to be as good as they have at home. For most locations, the cost of commodity bandwidth is low enough for organisations to over provide it cost effectively. By doing this, organisations allow for a wide variety of media rich applicationsavoid complex systems and policies to curb user requirements which push them to alternative methods, like mobile data. Service providers should provide an internet connection with a basic content filtering service to all wifi users filtered domain name system DNS is an appropriate solutionprovide a suitable amount of bandwidth for the planned number of users using commodity internet servicesavoid restricting sites or applications in an attempt to reduce bandwidth requirements in most locations its cheaper to over provide bandwidth. Service providers should consider the most cost effective way to improve user experience at a site, which may include transparent caching technologies to minimise the impact of software updatesquality of service Qo. S however, this is not a long term solution to inadequate bandwidthupgrading bandwidth using commodity internet services. Coverage. When deploying workplace wifi, service providers should manage channel selection radio frequency and reduce power if necessary, to minimise contention and overlapping ideally use the automatic channel selection features present in enterprise wifi management systems rather than manual configurationdeploy centrally managed AP hardware, each with at least 5 GHz frequency band and 8. MIMO supportensure theres sufficient uplink bandwidth from APs to the building switch infrastructureuse 8. GHz band which should only support 8. Serial Web Utility 3Com Phones. GHz bandconfigure a high minimum basic data rate and disable lower data rates this encourages clients to roam to APs with stronger signals, and increases capacity for all clientsplan for 5. AP vendors recommended client device count per AP radio stay well under the vendors published maximum figure you could provide one access point per block of 2. SSIDs per band per site each SSID will use up some bandwidth with beaconing, probe requests and probe responses. Service providers should consider selectively disabling SSIDs at places and frequencies they are not requiredselectively disabling 2. GHz radios on APs in large open plan areas with more than three APs to reduce interference between APs on the same frequency 5 GHz has considerably more channels and is better at providing non contending overlapped coveragemanaging channel width GDS recommends designing 8. MHz width channels wider channels channel bonding may be enabled on a best effort basis for 8. First, because you cant.

Service providers must ensure all users on any network have agreed to an AUP assume government users on government devices have already done soobtain user consent to use any non anonymised data, through an AUP or individual agreementprovide remote monitoring to manage usage and support the provider should handle all alerts and detect trends in usage which might require future upgrades.
