Connected everywhere

Citywide WLAN networks provide Internet access everywhere for everyone.
In today's world there are end-user devices available in vast ranges of prizes and forms.
Almost everyone owns or has access to netbooks, notebooks or mobile phones like the iPhone.

A seamless integration of well-known services like you find in hotels, restaurants and airports nowadays can be implemented with our solution almost effortless also in open areas, e.g. in urban space and public places.

Mesh networks

Meshed networks consist of multiple network nodes. Every single node is connected with one or more network nodes, thus building a meshed structure. Data to be transmitted is forwarded from node to node until reaching the next interconnection point and therefore without the need for additional backbone infrastructure.

City-WLAN meshed networks span whole premises with only a very limited number of wired access points. These networks provide a cost-efficient and highly available connection that is rapidly implemented.


City-WLAN-Networks offer an extraordinary variety of possibilities:

  • City internal data & communication network
  • Mobile Internet for visitors und citizen
  • Interactive city guide
  • Mobile payment and advertisement systems
  • Smart metering
  • Video surveillance
  • Providing information services:
    • Public transport info
    • Availability of parking lots
    • City maps
    • Hotels
    • Museums
    • Restaurants
    • Fun and recreation areas
    • Opening hours
    • Weather information


Security of your data is important. Therefore we are using the latest encryption mechanism and security features to protect each transmission.

SSL encryption is used when a customer authenticates at the gateway and additionally a VPN connection is established from the access gateway to the authentication server.
The radio links of the wireless backhaul use WPA2 encryption to ensure highest security.


Our Integrated Radio Masts blend extraordinary well into their environment and thus draw no unnecessary attention to them. All system components are mounted inside of the Integrated Radio Mast and invisible from the outside.

Multiple antennas inside the Integrated Radio Mast allow to separate the backhaul and access networks. There is no additional cabling necessary. The created meshed network topology offers two big advantages: high availability and load balancing.

brown-iposs' offer:

  • Turn-key WiFi networks
  • based on Integrated Radio Masts
  • Planning, design, site-survey
  • Integration with existing networks
  • Monitoring, 1st & 2nd level support

5G/LTE-A measuring campaign

An extensive measuring campaign about parameters for radio propagation modeling in LTE-Advanced and 5G has been run in behalf of a German Mobile Network Operator. 

The measuring campaign contained: 

  • Measurements in 4 cities at 9 sites
  • at antenna heights between 4 to max. 74 meter
  • constant output power: 40 dBm.

With the used measurement configuration, different radio conditions have been tested in 3,5 GHz domain as well as 900- and 1900 MHz bands. The evaluation of the measurements was done with the - among others - brown-iposs software WiMAP-4G.
