IP- and DECT-based Wireless Local Loop System IP- and DECT-based Wireless Local Loop System with IEEE 802.11b/g Broadband Internet Access

 
The RTX IP-DECT Wireless Local Loop (WLL) system, which was described in some detail in the December 2005 issue of RTX News, has now been rolled out in Romania, with several thousand base stations now being in operation in cities and rural areas. One of the optional features of the system; the ability to provide a WLAN service in the city deployments, has turned out to be very popular. This large-scale proof of concept is very encouraging and shows that the system is very cost-effective – both when used in rural areas as a means of providing basic telephone service, but also when used as a provider of limited mobility and broadband Internet access at a cost point much lower than the cost of similar cellular services. Based on this success, RTX is now ready to promote this system into other markets with a long list of benefits for the key players:
 

Benefits for governments/authorities

  • Very fast roll-out of voice and data service s to the general population: Large areas and a very large number of subscribers (millions) can be serviced by setting up base stations and base station clusters in a matter of days. It is not necessary to run copper wires to each individual subscriber.
  • Closing the Digital Divide1 at optimum cost: This system provides voice, mobility, and broadband Internet access and future upgrade opportunities at a fraction of the cost of cellular access.
 

Benefits for service providers

  • Expanded business opportunities: This system allows service providers to enter new markets and create new business opportunities by offering very fast roll-out of landline services and by offering broad-band Internet access and limited mobility services without the huge costs and political hurdles of acquiring cellular (GSM/CDMA/W-CDMA) spectrum licenses.
  • Additional revenue sources: Traditional landline services are nearing saturation in terms of service usage, leading to a stagnation of ARPUs2. This system offers two benefits. First of all, it attracts more users by offering one line per user rather than one line per household. Secondly, it generates new revenue streams through value-added services like broadband Internet access, text messaging service (SMS) etc.
  • Accelerated ROI: Service providers choosing the RTX IP-DECT WLL system, either as a supplement to landline or as an alternative to cellular, can realize significant cost savings and a faster ROI when it comes to network deployment and service provisioning costs.
  • Low-cost system management using advanced tools: The ability to monitor and upgrade the software in all system blocks, including the subscriber equipment, from a control center will significantly lower the cost of system management. One control center can monitor/manage several systems and it can be located anywhere in the world (with a connection via VPN over the Internet). The IP core of the system is based on standard IP elements that can be purchased from many suppliers.
  • Future-proof investment: Again, because of the unique software upgrade possibility, new features and new services can be offered to the market when the opportunity occurs – even without upgrading the hardware of the system.
  • Simple and easy deployment: Since the DECT standard uses Dynamic Channel Allocation, an IP-DECT WLL system requires significantly less network planning when compared to cellular networks. This helps to reduce complexities in network planning and helps accelerate deployment schedules, further accelerating ROI by decreasing the time lag from cash outflow on capital to inflow from subscribers.

Benefits for end users
  • An alternative to landline telephony service (or no service): In relatively underdeveloped regions that lack a basic telecommunications infrastructure and access to landline telephony services, the RTX IP-DECT WLL system offers end users a telephony solution that is inexpensive and effective. In addition, the system provides many of the features of a cellular service, such as network roaming and other value-added services.
  •  Value-added services, broadband Internet access: The value-added services offered by the Softswitch will be available to the end user – e.g. Call Forwarding, Conference Calls, Telephone Answering Functions and text messaging service (SMS). An Internet connection is available either via a modem connection (WTLU) or via WLAN.
  • Flexible subscriptions: The end user can benefit from the ability of the service provider to offer both low-cost low-feature subscriptions, and high-cost high-feature subscriptions.
  • A cost-effective alternative to traditional cellular: One of the key benefits of the RTX IP-DECT WLL system is that it offers end users a limited mobility and cost-effective alternative to cellular voice and data services.

The DECT standard is recognized in most countries in all parts of the world in various frequency ranges (1880-1900 MHz in Europe and most of Asia/parts of Africa, 1910-1930 MHz in the Americas). The RTX IP-DECT WLL system can operate in both frequency ranges.
 
Our customer base within our IP-DECT WLL system is growing steadily, and new features are continuously being added to the system. These new features can be made available to new systems as well as existing systems already in operation. This is possible due to the
unique capability to update software on all system elements (even the subscriber terminals) from the control center.
