Talk:Radio resource management

Review

The intro sentence definition could be clearer. It would be good to have a simpler introduction for the less technical reader.

The article seems to have a strong focus on cellular systems, with less on the other systems such as defence, administrative and wireless network aspects.

Static radio resource management and Dynamic radio resource management sections are mainly list. Each dot point could be expanded to a sentence to explain how the idea achieves its management objective.

<Some schemes are centralized, where several base stations and access points are controlled by a Radio Network Controller (RNC). Others are distributed, either autonomous algorithms in mobile stations, base stations or wireless access points, or coordinated by exchanging information among these stations.>

This (RRM) is a very under-emphasized field of developments. Much time, personnel, funding and attention must be paid to wireless link standards, computability and industry development that is necessary to fashion deployments that it tends to overshadow the growing importance and impact of RRM. Particularly as wireless is becoming broadband and based on IP protocols, network density, reuse factors, and distributed back haul and network resources are forcing greater consideration of RRM and corresponding distributed wired network topologies. Besides being a necessary and growing aspect of wireless network deployments, it is also where the most gains can be achieved.

The smart antenna and cognitive & adaptive radio methodologies are developing both for their own sake to limit device and base station interference and allow use of randomly (un)available spectrum. These technologies can further be harnessed to fashion more adaptive mesh, grip, tiered and virtual base stations with adaptive management capabilities. So, the groundwork of developments in wireless link technologies combined with the so-called 'smart' antenna technologies plus cognitive and adaptive spectrum resource capabilities can be organized into higher level schemes to provide what I call 'smart distributed wireless broadband networking'. Elements of this broad vision are showing up now in patents and proposals to standards groups and, in a preliminary way, in WiFi Mesh and femtocell deployments. From the number of patents and other groundwork activity, this looks to become a fast paced area of development and commercialization.

A note: the pace of development in wireless technologies and more directly in RRM and networking has accelerated over the past 2 years. The MIMO and AAS areas have ben extremely active. More recently smart and distributed wireless network technologies and management have ramped. While segments of patents have historically taken up up to several years to turn up in available products, the time frame has been compacting. Recent developments in 802.16j (WiMAX) MMR and related standards have seen patents filed almost simultaneous to proposals and adoption.

Survey: bit/s/Hz, (bit/s)/Hz or bit·s⁻¹·Hz⁻¹ as Spectral efficiency unit?

Please vote at Talk:Eb/N0#Survey on which unit that should be used at Wikipedia for measuring Spectral efficiency. For a background discussion, see Talk:Spectral_efficiency#Bit/s/Hz and Talk:Eb/N0#Bit/s/Hz. Mange01 (talk) 07:21, 16 April 2008 (UTC)
