The optimum method of delivering the Vintage radio service is by the use of an Internet radio receiver and a broadband connection. The bandwidth used is minimal (about 30 kbps) and given a three hour a day usage there should be no exceeding of the standard offering (15 Gbyte) for usage allowance. I estimate that at 40 kbps the download size will be around 13 Gbyte for a 3 hr day 30 days a month. If O2 is chosen for service delivery there is no download limit anyway. Other providers do the same depending on the tariff selected. http://www.o2.co.uk/broadband

It is strongly suggested that in the case of residential homes that any “friends of the residents group” is involved as part of the process as a way of helping with any equipment and service financing. The “friends” are normally the offspring of the residents.

The following paragraphs look at the various options for infrastructure and radio equipment. It will be seen that the options below are progressively more complicated and with the exception of option 1 (and possibly 2), the solutions involve interaction with the office LAN setup in the premises with the risk of disruption at installation time and at the time of any malfunction. This aspect needs to be considered in the overall strategy. A possible solution here is the installation of a separate broadband service which will need a new phone line.

It is strongly suggested that a survey is carried out as part of the “sign up” process, this to include items such as:

a) Broadband status ( exist/not exist/type of existing connection)
b) WiFi workability (distance etc)
c) Any existing audio distribution system that can be utilised


Budget costs are hardware only.

All broadband supply is subject to supplier survey in respect of deliverability. O2 uses BT copper cabling with ADSL2 technology (higher speed).

1. Infrastructure

There are various configurations that can be experienced when an investigation is made into how the Internet can be used to deliver service. These notes only refer to delivery of broadband over standard exchange lines, not “cable”. In all cases the plan is to use WiFi to link the broadband to the Internet radio to enable the Vintage radio service radio to be deployed to best effect.

(a) No broadband present.

This is the simplest situation and in many respects the most ideal one.There will be a phone line in the office which can be “broadband enabled” provided the premises is within working range of an Exchange. It is suggested that a standard broadband kit is ordered which will contain the necessary wireless router and telephone filters. Additional filters may be needed (you normally get two but more can be bought from the likes of B&Q for about £3) depending on phone outlets. It is suggested that the O2 offering (uses BT copper cables) is considered as it is at a low cost and comes with a free wireless router. Also no download limit.

Even with this “simplest” solution a survey is recommended as a residential home can be large and there may be some distance between the WiFi router and the communal lounge. It is worth noting that a WiFi router can normally provide coverage around a standard house provided the signal does not have to traverse through too much brick as it attenuates the signal.

Budget costs

Suggest O2 service at £7.50/month inc wifi router


(b) Broadband on site and with wireless router.

Again ideal as the Internet radio can be easily added to the network on receipt of the encryption key from the office manager.

Budget costs

Zero


(c) Broadband on site with router but no wireless

The router will invariably be an ethernet-based device with office PCs connected by Ethernet cables. With this configuration we will need to add an access point by using one of the spare Ethernet connection sockets. If none are available then another hub will need to be “slaved” from the original one at extra cost.(est £50)

Budget costs

Add WiFi access point £60


(d) Broadband on site but single office PC connected by a broadband modem

This configuration will need the replacement of the simple broadband modem by a WiFi router. With a modem the logon details are held in the PC whereas with a router the sign in data is held in the router. Instances like this are less common than they were.

Budget costs

Contact existing broadband supplier about upgrade to WiFi (which will include a router)


(e) New broadband service

To avoid any “commercial” complications related to disruption

Fit new phone line and ADSL wireless router

Budget costs

BT line connection £125, rental £11.25/month (£135/annum). Suggest ban outgoing calls to avoid abuse.

Suggest O2 broadband service at £7.50/month (£90/annum) inc wifi router


2. Internet Radios.


Prime selection criteria should be.

(a) WiFi enabled…we don’t want cables around the floor (Health and Safety etc)

(b) Decent speaker set that will enable enough volume to cover a (say) residential home lounge. The O2 Joggler shown below is more for small bedside room use.

This link can be used to see what is available in the market. Two products are shown below.

Budget cost around £160


Sample Products

Pictured below are two possible products that could fulfil the requirement. The Roberts radio WM202 is listed at £153.27 and the O2 Joggler ( a combined radio and digital photo frame) is around £100 budget. None have been tested as yet but are offered as proof of product availability. Follow the hyperlinks for more information.
